WebThus, Shh is involved in maintaining the appropriate number of cells in the LC. While elevated levels of bone morphogenetic protein 4 (BMP4) did not attenuate tyrosine … The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. FGF-8 is important and necessary for setting up and maintaining the midbrain/hindbrain border (or

WebAccordingly, the FGF8, SHH, WNT, and BMP signaling pathways play crucial roles during the development of the mDA neurons in the mammalian embryo. Moreover, these morphogens are essential for the generation of stem cell-derived mDA neurons, which are critical for the modeling, drug screening, and cell replacement therapy of PD.
