摘要:
Fibroblast growth factors (FGFs) are structurally related mitogens that can regulate the differentiation of a wide variety of cells. As a step towards elucidating the developmental roles played by one of these factors, we have used in situ hybridization methods to examine expression of the murine Fgf-5 gene during embryogenesis. Fgf-5 RNA was detected at seven distinct sites in the developing mouse embryo: (1) postimplantation epiblast (embryonic day 5 1/4-7 1/2), (2) lateral splanchnic mesoderm (E9 1/2-10 1/2), (3) lateral somatic mesoderm (E10 1/2-12 1/2), (4) myotomes (E10 1/2-12 1/2), (5) mastication muscle (E11 1/2-14 1/2), (6) limb mesenchyme (E12 1/2-14 1/2), and (7) acoustic ganglion (E12 1/2-14 1/2). At several of these sites, expression is spatially restricted within the tissues. We offer several hypotheses regarding the roles of FGF-5 in murine development.
