The bHLH transcription factor Ascl1a is essential for the specification of the intestinal secretory cells and mediates Notch signaling in the zebrafish intestine.

abstract：:Previous studies have shown that cultured Schwann cells secrete platelet-derived growth factor (PDGF) and express PDGF receptors which transmit a mitogenic response particularly when their levels are upregulated by elevation of intracellular cAMP. In this study the expression of PDGF and PDGF alpha- and beta-receptors...
