Abstract： 目的研究磷脂酶C-γ1在胚胎及新生小鼠脑组织的表达.方法制备胚胎及新生小鼠脑组织标本,进行石蜡包埋并切片,采用免疫细胞化学方法检测磷脂酶C-γ1的表达情况,并进一步利用Western blot技术对磷脂酶C-γ1的表达进行初步定量.结果免疫组织化学的结果表明,在胚胎脑组织中磷脂酶C-γ1的表达比较广泛,各种细胞均有表达,没有细胞特异性;而在出生后5 d的脑组织,磷脂酶C-γ1特异地表达于大脑皮质层及神经核团内的神经元,周围的神经胶质细胞不表达.Western blot的结果表明,在胚胎各个组织(脑、四肢、心、肾、胃、胰等)中脑的表达最高,脑内的表达又随胚胎发育过程胚胎第11天(E11)、E14、E18、出生后5 d逐渐降低.结论磷脂酶C-γ1相关信号通路对于小鼠胚胎脑的发育具有重要生物学作用,可能对于脑神经元发育、生长、分化等具有重要作用.
