BFGF immunoreaction was detected at 3-weeks' embryonic neuroepithelium, and remained positive throughout various development a l stages examined, whereas NGF immunoreaction appeared after 4-weeks. The expres sion varied gradually with the development of embryos. There was no specific EGF immunoreaction in all tissues and stages examined. The occurrence and distribut ion of FGFR, NGFR and EGFR were similar, and their expression altered with the development.

结果显示bFGF和NGF的表达时序不同，b FGF阳性细胞出现较早，在所检测的各个发育阶段均呈阳性表达，而NGF出现较晚，随着胚龄增加，免疫阳性着色逐渐增强，bFGF分布较NGF广泛，而EGF在所检测的各个发育阶段均呈阴性。flg、TrkA、EGFR表达时序和分布相似，三者在所检测的各个发育阶段均呈阳性。
