... that are essential for ionocyte specification,differentiation, ionoregulation, acid–base balance and the number of cells expressing these genes increased. For instance, epithelial Ca 2+ channel (EcaC; an ionoregulatory protein) mRNA increased in parallel with the level of Ca 2+ influx, revealing a functional...

... is well adapted to its burrowing life style. We demonstrate that there is a trade-off between regeneration in length and functional recovery for feeding (differentiation index). The amount of tissue lost (length lost), which represents the quantity of tissue needed to completely regenerate an intact arm...

...Daisuke Uchida; Michiaki Yamashita; Takeshi Kitano; Taisen Iguchi SUMMARY Large numbers of apoptotic early diplotene oocytes were observed during the transition from ovary-like undifferentiated gonadal tissue to testes during sex differentiation in presumptive males of the zebrafish ( Danio rerio...

... that the differentiation of fast muscle commences in the medial domain of the somite before the differentiation and migration of the slow muscle precursors. Later, as the differentiation of fast muscle progressively spreads from the inside to the outside of the myotome, slow-MyHC-expressing cells become visible medially...

...Kiyono Shiraishi; Junya Hiroi; Toyoji Kaneko; Manabu Matsuda; Tetsuya Hirano; Takao Mori SUMMARY To examine the functional differentiation of chloride cells in the yolk-sac membrane of tilapia ( Oreochromis mossambicus ) embryos, we developed a ‘yolk-ball’ incubation system in which the yolk sac...

... regenerating antler cartilage as a site of osteoclastogenesis in vivo . An in vitro model was then developed to study antler osteoclast differentiation. Cultured as a high-density micromass, cells from non-mineralised cartilage supported the differentiation of large numbers of osteoclast-like multinucleated...

..., following exposure to platelet-derived growth factor (PDGF), a factor important in the lineage progression of oligodendrocytes, or in the presence of dibutyryl cyclic AMP at 39 °C (the non-permissive temperature), the cells underwent morphological and antigenic differentiation to cells characteristic...

... GS/B variant of the papovavirus JC. The proliferation and differentiation of two clonal cell lines have been studied. The cells of these lines display the morphology of primary Schwann cells and express Schwann cell differentiation markers such as the S-100 protein, laminin, the low-affinity receptor...

... epithelia have been studied by transport physiologists, most work has been focused on identification and description of the differentiated transport exhibited by cultured epithelia. Epithelia formed by a continuous line of cells derived from pig kidney (LLC-PK 1 ) exhibit sodium-coupled glucose transport...
