| cultures of skin fragments of salamandra salamandra salamandra (l.) larvae. | as part of a study on the pigmentary system of salamandra salamandra salamandra (l.), we cultured skin fragments of 7-10-day-old larvae in order to examine the expression of molecules implicated in cellular adhesion and migration and in regulating cell-cell relationships. keratinocytes, fibroblasts, leydig cells, xanthophores, and melanophores migrated from the fragments and were observed in the outgrowth. keratinocytes and fibroblasts organized into an epidermal layer and an underlying "dermal ... | 1998 | 9585248 |
| xanthophore migration from the dermis to the epidermis and dermal remodeling during salamandra salamandra salamandra (l.) larval development. | during larval development of salamandra salamandra salamandra chromatophores organize to form the definitive pigment pattern constituted by a black background with yellow patches that are characterized by epidermal xanthophores and dermal iridophores. simultaneously the dermis undergoes remodeling from the larval stage to that typical of the adult. in the present study we ultrastucturally and immunocytochemically examined skin fragments of s. s. salamandra larvae and juveniles in order to invest ... | 2003 | 12519125 |
| cytochemical and immunocytochemical investigations on epidermal mitochondria-rich cells in salamandra salamandra salamandra (l.) larvae. | in the present study we set out to investigate the expression of e-cadherin, n-cadherin, beta 1-integrin, fibronectin and vitronectin in the mitochondria-rich cells (mrc) of the skin of salamandra salamandra salamandra. moreover mrc were stained with five lectins (triticum vulgaris; dolichos biflorus; glycine max; arachis hypogaea and canavalia ensiformis). larval mrc expressed both adhesion molecules and extracellular matrix glycoproteins and bound all lectins tested. juvenile mrc did not react ... | 1997 | 9467926 |
