These findings show the co-existence of G-like and I-like substances in rat embryo pancreatic endocrine cells between the 13th and 17th days of gestation, after which the I-like cells proliferate rapidly, and undergo definitive differentiation from the G-like cells....
Cellular differentiationis at present interpreted in terms of the theory of variable gene activity, one of the most potent unifying theories to develop in the biological sciences during this century. This theory proposes that cell specialization results from the function of the appropriately selected g...
The postovulatory rise in ovarian progesterone induces profound remodeling and differentiation of the estradiol-primed endometrium. This change, termed decidualization, is crucial for embryo implantation and maintenance of the pregnancy. To date, activation and crosstalk of cAMP- and progesterone-mediated ...
We next focus on identifying genes that control hypothalamic regionalization and neurogenesis in the early embryo, and integrate these findings to generate a Hypothalamic Developmental Database (HyDD), which identifies selective markers of each region of the developing hypothalamus and prethalamus. We ...

Segmentation is a fundamental feature of the vertebrate body plan. This metameric organization is first implemented by somitogenesis in the early embryo, when paired epithelial blocks called somites are rhythmically formed to flank the neural tube. Recen

Cell DifferentiationDyesEmbryoHepatocytes metabolism细胞培养细胞分化染料胚胎吲哚花青绿Background and Aims. Embryonic stem (ES) cells have a pluripotent ability to differentiate into a variety of cell lineages in vitro. We have recently found the emergence of cell clusters that show the cellular uptake ...
Cells of the embryo-surrounding region appear to coordinate development of the embryo and endosperm. As the seed matures, SE cells assimilate starch and protein stores, undergo DNA endoreduplication, and finally undergo programmed cell death. In contrast, aleurone cells follow a maturation program ...
Cell DifferentiationEmbryo, NonmammalianTwo recent large-scale genetic screens in zebrafish have identified many mutations that affect differentiation in a variety of organ systems, particularly the notochord, the neural crest and the blood. The combination of these newly identified mutations and well ...
