| difference of the in vivo responsiveness to thyrotropin stimulation between the neotenic and metamorphosed axolotl, ambystoma mexicanum: failure of prolactin to block the thyrotropin-induced thyroxine release. | basal and tsh-induced plasma concentrations of t4 have been measured by radioimmunoassay in the neotenic and metamorphosed male axolotl ambystoma mexicanum both before and after an ovine prolactin pretreatment. all injections are made into the vena abdominalis. basal levels of t4 are low in neotenes (85 +/- 19 pg/ml) and somewhat higher in metamorphosed ambystoma (171 +/- 39 pg/ml), but are increased during metamorphosis (1094 +/- 138 pg/ml). following injection of 5 mu bovine tsh circulating le ... | 1984 | 6510692 |
| [nuclear behavior of embryonic cells and growing oocytes from the clawed toad in the cytoplasm of maturing axolotl oocytes]. | the behaviour of the nuclei of the x. laevis vitellogenic oocytes was studied by their transplantation into the cytoplasm of the axolotl maturing oocytes. after the germinal vesicle breakdown, in the case the transplanted nuclei were located close to each other a common giant spindle united the chromosomes of all transplanted nuclei. a mosaic spindle united sometimes the chromosomes of the two amphibian species. the embryonic nuclei transplanted in the cytoplasm of the maturing oocytes formed, a ... | 2006 | 6504501 |
| regeneration of surgically created mixed-handed axolotl forelimbs: pattern formation in the dorsal-ventral axis. | the regeneration of surgically created mixed-handed limb stumps is examined in the axolotl. operations were performed in the lower arm and upper arm regions and grafts were allowed to heal for approximately one month prior to amputation or were amputated immediately. in the lower arm group both anterior and posterior limb halves were inverted, whereas only posterior halves were inverted in the upper arm group. almost all the limbs regenerated were normal in the anterior-posterior axis, whereas a ... | 1984 | 6491582 |
| the pigmentary system of developing axolotls. ii. an analysis of the melanoid phenotype. | the melanoid mutant in the mexican axolotl (ambystoma mexicanum) is analysed with respect to the differentiation of pigment cells. pigment cells were observed with the transmission electron microscope in order to determine any unusual structural characteristics and to determine what happens to each of the cell types as development proceeds. chemical analysis of pteridine pigments was also carried out, and changes in pteridine biosynthesis were found to correlate well with changes in xanthophore ... | 1984 | 6470606 |
| the pigmentary system of developing axolotls. i. a biochemical and structural analysis of chromatophores in wild-type axolotls. | a biochemical and transmission electron microscopic description of the wild-type pigment phenotype in developing mexican axolotls (ambystoma mexicanum) is presented. there are three pigment cell types found in adult axolotl skin - melanophores, xanthophores and iridophores. both pigments and pigment cells undergo specific developmental changes in axolotls. melanophores are the predominant pigment cell type throughout development; xanthophores occur secondarily and in fewer numbers than melanopho ... | 1984 | 6470605 |
| cellular contribution to supernumerary limbs resulting from the interaction between developing and regenerating tissues in the axolotl. | the relationship between limb development and limb regeneration is considered with regard to the mechanisms by which pattern is established during limb outgrowth. in a previous paper (muneoka, k. and bryant, s. v. 1982 nature (london) 298, 369-371) the interaction between cells from the developing limb bud and the regenerating limb blastema was found to result in the production of organized supernumerary limb structures. in this paper the relative cellular contribution from developing and regene ... | 1984 | 6468758 |
| cellular contribution to supernumerary limbs in the axolotl, ambystoma mexicanum. | using the triploid cell marker, the cellular contribution from graft and stump to the supernumerary limbs which result from controlateral grafts of limb buds and regeneration blastemas in the axolotl has been analyzed. grafts were made so as to appose anterior and posterior limb positions. overall, the contribution from graft and stump tissue was found to be approximately equal although the position of the boundary between the two was variable from limb to limb. this result is consistent with mo ... | 1984 | 6468757 |
| accumulation and localization of troponin-t in developing hearts of ambystoma mexicanum. | troponin-t (tn-t) expression in developing hearts of axolotls, ambystoma mexicanum, was studied with the use of polyclonal and monoclonal antibodies and sds-polyacrylamide gel electrophoresis. in precontractile hearts (stage 32/33), tn-t was present in addition to myosin, actin and tropomyosin as evidenced by the presence of the protein bands in sds-gels and by indirect immunofluorescence. tn-t was localized in amorphous collections at the peripheries of these precontractile cells. hearts of nor ... | 1984 | 6442732 |
| effects of trh, bovine tsh, and pituitary extracts on thyroidal t4 release in ambystoma mexicanum. | circulating levels of t4 are measured by radioimmunoassay after intravenous injection of trh, bovine (b) tsh, and pituitary extracts in the mexican axolotl (ambystoma mexicanum). very low control levels of t4 are found (53 +/- 3 pg/ml (n = 27), but they are increased sevenfold following injection of 1/2 pars distalis extract or 1/2-1/10 iu b-tsh. increased levels following these injections are found in plasma up to 48 hr after the injection. an in vitro assay also indicates that a 1/2 pars dista ... | 1983 | 6413295 |
| [formation of the gray crescent, induced in axolotl oocytes during maturation, depends on factors of nuclear origin]. | inhibitors of protein synthesis can elicit the precocious appearance of a grey crescent (gc) in in vitro maturing ambystoma mexicanum oocytes. this treatment however fails to induce gc formation when the oocytes are enucleated before initiation of maturation. the ability to form a gc is reestablished in enucleated oocytes by the injection of nucleoplasm from a normal oocyte, either before or after injection of the inhibitor. in the latter case, the gc appears even though the protein synthesis le ... | 1983 | 6412990 |
| the distribution of marked dermal cells from small localized implants in limb regenerates. | numerous experiments have demonstrated that skin has a profound influence on the pattern of limb regeneration in urodeles. in this investigation, the fate during regeneration of marked cells derived from narrow strips of skin inserted into different positions around the limb circumference has been followed. skin strips were taken from triploid axolotls and transplanted into diploid sibling animals. the distribution of trinucleolate cells was determined at the site of amputation and in the regene ... | 1984 | 6389219 |
| distribution of desmosomal components in the tissues of vertebrates, studied by fluorescent antibody staining. | in previous work we used immunofluorescent staining with specific antibodies to study the distribution of five desmosomal antigens in the epithelia of different vertebrate animals. we showed that all five antigens were present in all epithelia studied in human, bovine, rat, guinea pig, chick and frog (rana pipiens) tissues. it was concluded that desmosomes are highly conserved structures. this paper extends those studies: by including three other species, a lizard (lacerta viridis), the axolotl ... | 1984 | 6378940 |
| positional information in the forelimb of the axolotl: properties of the posterior skin. | two series of experiments were carried out to investigate the properties of the positional information carried by posterior skin of the axolotl forelimb. the skin was assayed by grafting it to the anterior side of a normal limb and then amputating through the graft region. the formation of a double posterior regenerate indicates that the grafted skin carried the posterior coding. in the first series, double posterior limbs were created by grafting posterior half limb rudiments to the flank of ta ... | 1983 | 6348201 |
| maturation of transplantation antigens in ambystoma mexicanum. | both juvenile (14-16 week) and adult (18 month) ambystoma mexicanum reject skin allografts from adult ambystoma more speedily than they reject such grafts from juvenile axolotls. donor-specific histocompatibility antigen, prepared from splenocytes, is more effective in inhibiting adult host splenocyte migration when the antigen is prepared from spleen cells from adult, rather than from juvenile ambystoma. the thymus is fully developed in juvenile ambystoma, suggesting that the delayed kinetics o ... | 1983 | 6341109 |
| anchoring filaments of the amphibian epidermal-dermal junction traverse the basal lamina entirely from the plasma membrane of hemidesmosomes to the dermis. | an electron microscopical study of the epidermal-dermal junction in the axolotl and adult rana pipiens has been carried out. this shows that filaments of about 12nm in diameter, known as anchoring filaments, pass from the hemidesmosomes at the base of the epidermal cells across the basal lamina to the dermis. there they may unite to form broader fibres, known as anchoring fibrils, or may simply form bundles. in the axolotl, particularly, the anchoring fibrils or bundles of anchoring filaments, e ... | 1984 | 6335885 |
| axonal pathfinding in the absence of normal pathways and impulse activity. | retinal axons were challenged to grow to their targets both along abnormal pathways and in the absence of impulse activity. eye primordia were first transplanted from normal to ectopic sites in axolotl embryos. most of the hosts were genetically eyeless, others were enucleated normal embryos. these axolotl embryos were then parabiotically joined to california newt embryos. both operations were completed by stage 28, which is before axons have left the eye. the result of the parabiosis was a para ... | 1984 | 6325605 |
| ribosomal 5s genes in relation to c-value in amphibians. | we have measured the amount of 5s-ribosomal dna in the genomes of xenopus laevis, triturus cristatus carnifex and ambystoma mexicanum, three species of amphibians which have widely different c-values. our best estimate is that these organisms have about 24,000, 32,000 and 61,000 5s-genes per haploid genome respectively. a trend to increasing 5s gene copynumber with increasing c-values in amphibians is apparent, probably linked to the need to supply more ribosomes to the larger cells which are as ... | 1983 | 6304650 |
| hormonal control of glycogenolysis and the mechanism of action of adrenaline in amphibian liver in vitro. | in in vitro cultures of liver from ambystoma mexicanum glycogenolysis was stimulated by adrenaline, glucagon, and vasopressin in a dose-dependent manner. maximum activity was seen at 10(-6) m hormone while 10(-9) m was without effect. dibutyryl cyclic amp (10(-3) m) stimulated glycogenolysis maximally although 10(-5) m had no effect. the glucose release brought about by adrenaline was blocked by the beta-adrenergic antagonist propranolol but not by prazosin or yohimbine which are alpha 1- and al ... | 1983 | 6301936 |
| suppression of sprouted synapses in axolotl muscle by transplanted foreign nerves. | 1. the supracoracoideus (s.c.) muscle of the axolotl shoulder is innervated by two nerves, the anterior and posterior s.c. nerves. the posterior nerve was induced to make synapses outside its normal territory in the muscle by removing a segment of the anterior nerve. intracellular recording indicated that the efficacy of transmission from posterior nerve terminals outside their normal territory increased over several weeks prior to the return of the anterior nerve. 2. the anterior nerve reinnerv ... | 1980 | 6259337 |
| equilibrium properties of a voltage-dependent junctional conductance. | the conductance of junctions between amphibian blastomeres is strongly voltage dependent. isolated pairs of blastomeres from embryos of ambystoma mexicanum, xenopus laevis, and rana pipiens were voltage clamped, and junctional current was measured during transjunctional voltage steps. the steady-state junctional conductance decreases as a steep function of transjunctional voltage of either polarity. a voltage-insensitive conductance less than 5% of the maximum remains at large transjunctional vo ... | 1981 | 6259274 |
| [effects of exogenous tsh on the thyroid activity of adult or neotenic amphibians]. | in adult anuran and neotenic urodela, bred in laboratory conditions, the levels of plasma thyroid hormones are undetectable (t3 less than 50 ng/100 ml, t4 less than 5 ng/100 ml). thyroid function can be reactivated after ovine tsh treatment. under those conditions, metamorphosis is induced in the axolotl and t4 plasmatic levels reaches 0,53 +/- 0,13 micrograms/100 ml and those of t3 9 +/- 2,64 ng/100 ml. in adult anuran, thyroid reactivation under thyrotropic treatment determines an increased se ... | 1982 | 6220788 |
| improved techniques for use of the triploid cell marker in the axolotl, ambystoma mexicanum. | techniques for using the triploid cell marker for studying cell lineage during the development and regeneration of the axolotl limb are described. triploid animals possess cells with three nucleoli while diploid animals possess cells with two nucleoli. we have developed a technique for isolating the limb dermis as a sheet of cells for whole-mount analysis of cellular ploidy. whole-mount tissue preparations as well as paraffin-embedded sectioned tissues were stained specifically for nucleoli with ... | 1984 | 6205921 |
| the genes coding for 4 snrnas of drosophila melanogaster: localization and determination of gene numbers. | four small nuclear rnas (snrnas) have been isolated from drosophila melanogaster flies. they have been characterized by base analysis, fingerprinting, and injection into axolotl oocytes. the size of the molecules and the modified base composition suggest that the following correlations can be made: snrna1 approximately u2-snrna; snrna2 approximately u3-snrna; snrna3 approximately u4-snrna; snrna4 approximately u6-snrna. the snrnas injected into axolotl oocytes move into the nuclei, where they ar ... | 1983 | 6191277 |
| expansion of the visual projection to the tectum of axolotls during metamorphosis. | during artificially induced metamorphosis in axolotls, the indirect visual projection from the ipsilateral eye develops followed by the expansion of the contralateral direct projection to occupy most of the tectal surface. during expansion the ipsilateral input is temporarily lost indicating the functional interdependence of the two projections. final stabilization of the projections and congruence of the ipsilateral and contralateral inputs is achieved a month after arrival on land. | 1982 | 6185185 |
| has prolactin an intermedin-like activity on the integument of the axolotl? | skin explants of the neotenic form of ambystoma tigrinum (axolotl) have been kept in culture during several days. when alpha-msh or prolactin are added to the medium, a dispersion of melanin in melanosomes is observed. the reaction is reversible in the case of prolactin when the explants are transferred in the medium without hormones. furthermore with prolactin, expansion of melanin in dermal melanophores is a more permanent and highly reproducible phenomenon, compared with the action of alpha-m ... | 1981 | 6176199 |
| the alveolar-lining layer in the lung of the axolotl, ambystoma mexicanum. an electron-microscopic study using heavy metal complexes. | lungs of neotenic larvae of ambystoma mexicanum were prepared for maintaining the air-tissue boundary during aldehyde fixation. four methods of postfixation were applied: 1) osmium tetroxide followed by en-bloc staining with uranyl acetate and phosphotungstic acid, 2) ruthenium redosmium tetroxide, 3) osmium tetroxide-ferrocyanide, and 4) tannic acid-osmium tetroxide. three types of cells line the inner surface of the axolotl lung: 1) pneumocytes, covering the capillaries with flat cellular exte ... | 1982 | 6174238 |
| is the na+,k+-atpase symmetrically distributed in the neuroepithelium of the vestibular system in the axolotl (ambyostoma mexicanum)? | this study was undertaken to assess the localization of the na+,k+-atpase in the neuroepithelial cells of the macula sacculi. in vitro perilymphatic (basolateral) perfusion with ouabain produced a significant drop in the membrane potential. endolymphatic (apical) application of ouabain had practically no effect on membrane potentials. this suggests that na+,k+-atpase is asymmetrically distributed in the neuroepithelial cells. | 1984 | 6151945 |
| the effects of adenyl compounds on the heart of the axolotl (ambystoma mexicanum). | in the spontaneously beating axolotl atrium, adenosine 5'-triphosphate (atp) produced initial excitation followed by inhibition and then by a secondary excitation. this third phase of the atp response was only seen in electrically driven preparations in the presence of 8-phenyltheophylline (8-pt), an adenosine receptor antagonist. alpha,beta-methylene atp (apcpp), a stable analogue of atp, produced only excitatory effects, while adenosine and beta,gamma-methylene atp (appcp), a slowly degradable ... | 1983 | 6140115 |
| enzyme clusters during the metamorphic period of ambystoma mexicanum: role of thyroid hormone. | enzyme activities and dna content have been measure in axolotl liver during the metamorphic period (4-8 months after spawning). three different types of enzyme activity profiles were observed. in the type i profile (carbamoyl-phosphate synthase, arginase, ornithine transcarbamoylase, and glutamate dehydrogenase) enzyme activity is high in the youngest animals studied, and shows a minimum at 5 months followed by a maximum at 8 months of age. thereafter activities do not change or slightly decreas ... | 1982 | 6128371 |
| off-pathway synaptic transmission in the outer retina of the axolotl is mediated by a kainic acid-preferring receptor. | intracellular recordings were made from off-centre bipolar cells and horizontal cells in the superfused axolotl retina eyecup preparation. bath-applied (+/-)cis-2,3-piperidine dicarboxylic acid (pda), gamma-d-glutamylglycine (dgg), l-glutamic acid diethyl ester (gdee), (+/-)2-amino-5-phosphonovaleric acid (2-apv) and magnesium ions were assessed as antagonists of the actions of the photoreceptor transmitter. the rank order of antagonist efficacy was pda greater than dgg greater than greater than ... | 1984 | 6093015 |
| a voltage-gated hydrogen ion current in the oocyte membrane of the axolotl, ambystoma. | membrane currents in the immature oocyte of the urodele amphibian ambystoma were studied using the two-micro-electrode voltage-clamp technique. a current carried by h ions (ih) constituted the major portion of outward current activated by depolarizations from the resting voltage (about -60 mv). net inward current was not observed at this developmental stage. the reversal potential for ih measured from tail currents obtained in two step voltage-clamp experiments shifted by 54 mv per unit change i ... | 1984 | 6086909 |
