In addition, Lai and Doe found that introducing similar pulses of Prospero into cells experimentally can drive proliferating embryonic neuroblasts into premature quiescence.
Dr. Lorenz Studer at Sloan-Kettering converthe thembryonicicellsls into brain cells.
He was investigating how cells specialize in a developing embryo when he and a colleague, Dr. Robert W. Briggs, devised a delicate microsurgical technique of transplanting the nucleus from a single advanced embryonic cell into an egg whose nucleus had been removed.
Go past the embryonic bar into the impressive velvet-lined, 1,900-seater auditorium and you discover the stage set for a fantasy from Old Peking, and Widow Twankey's Laundry.
Researchers in Israel have converted human embryonic cells into heart muscle, and other groups are working out ways to drive the cells down paths of development that lead to brain and pancreas tissue.
We then coax a cell line made from an embryonic kidney into taking up the Trojan horse plasmid.
The feasibility of transforming embryonic endoderm into different cell types is tightly controlled by mesodermal and septum transversumal signalings during early embryonic development.
The molecular and morphogenetic mechanisms that pattern and subdivide the embryonic cloaca into these different epithelial structures are still unclear.
Accordingly, the window of developmental vulnerability to chlorpyrifos is likely to extend from the embryonic period into postnatal life.
Sex determination and development begin early in gestation, with the differentiation of the embryonic gonad into either testes or ovaries.
