| studies on tail regeneration and homeotic transformation in anuran tadpoles. | anuran tadpoles are excellent models for regeneration studies. the tail, an organ essential for swimming for the aquatic tadpole, regenerates completely following injury or amputation. however, treatment with the morphogen, vitamin a or retinoic acid inhibits normal tail regeneration and induces homeotic transformation of tail to limbs. this phenomenon was discovered for the first time in the indian marbled balloon frog uperodon systoma in the developmental biology laboratory of utkal university ... | 2020 | 32659020 |
| introduction of developmental biology at utkal university, (odisha, india). | the paper deals with the background and the establishment of a developmental biology laboratory in utkal university in odisha state. it describes the process from a humble beginning with limited facilities into a leading research centre, initially for amphibians and later for the endangered olive ridley (lepidochelys olivacea) turtle. starting from the biology, reproduction and development in many anurans, the laboratory took up research on regeneration, especially on super-regeneration in tadpo ... | 2020 | 32659019 |
| limbs generated at site of tail amputation in marbled balloon frog after vitamin a treatment. | niazi and saxena first observed that vitamin a has an inhibitory and modifying influence on tail regeneration in bufo andersonii tadpoles. a positive relationship was later found between the inhibiting influence of vitamin a and the developmental stage of the regenerating tail in the same species. there have been several subsequent reports on the effects of vitamin a and its derivatives on limb development and regeneration. thus in regenerating amphibian limbs, application of retinoids produces ... | 1992 | 1731249 |
