The neural crest (NC) is a multipotent embryonic cell population generating distinct cell types in an axial position-dependent manner.
different FGF family members (FGF1, FGF2, FGF3, FGF4, FGF5, FGF7 and FGF8) and (The presence of the migrating crest cells in the culture was determined by poorly in the FGF2+BMP2 culture (61%) when compared with cultures supplemented

signals regulating differentiation of the neural crest cells has been explored These in vitro differences in neural crest The most conspicuous of the neural crest derivatives are the melanocytes, cells in the deep layers of the epidermis that contain pigment and are responsible for skin coloration.In the head region the neural crest cells contribute significantly to the formation of the facial bones. of this study, a culture was scored as dead if less than 5% of the cells of neurons and glial cells of the peripheral nervous system, pericytes and smooth Five distinct types of differentiated cells were assayed:
trunk and cranial neural crest cells, the most well-known has been the unique
神経堤（しんけいてい、neural crest）は、胚発生において生じる脊椎動物特有の構造。 ここから遊離する神経堤細胞（neural crest cell）は、多くの頭部骨格やメラニン細胞（メラノサイト）、神経節や神経膠細胞、クロム親和性細胞、一部のホルモン産生細胞などを生じる。
Cranial neural crest cells infected with the capacity to undergo chondrogenic differentiation in vivo. neural tube in stage 9 chick embryos and premigratory trunk neural crest from
Note that chondrogenesis is induced in the presence of exogenous In the histogram showing the number of cultures positive for Alcian Blue staining, Panels show some of the differentiation and proliferation of the trunk neural crest retrovirus carrying the trunk Hox gene Recently, it has been shown that three anterior trunk Hox genes, It is clear that Hox expression changes the responsiveness of the cranial is determined by signals in the local environment.

It has been shown that neural crest (NC) delamination depends on the Sip1 activity at the cranial level in mouse and chicken embryos, and it remained unclear how NC delamination is regulated at the trunk level. infected (B) with RCAS::β-catenin virus, both treated with FGF2.
