机体内网状内皮系统细胞(巨噬细胞)的吞噬活动,是重要的防御机制之一。经典方法多是利用它的吞噬特性,通过注射染料以研究其形态和功能。对于这类细胞在个体发生中的细胞分化情况,过去清野(1928),Perez Del Castillo(1957)及 Kent(1961)氏等曾在鸡胚中进行过观察,但对鸡胚肝脏巨噬细胞的发生时间及分化规律,意见尚不一致。至于在哺乳动物,对其巨噬细胞发生的系统性研究,仅见一些零星的报导。张作干氏
The body’s reticuloendothelial system cells (macrophages) phagocytosis, is one of the important defense mechanisms. The classic method is to use its phagocytic properties, by injecting dyes to study its morphology and function. For the differentiation of such cells in the development of individuals, Ching Ye (1928), Perez Del Castillo (1957) and Kent (1961) have been observed in chicken embryos, but in chicken embryo liver macrophages Occurrence of time and differentiation, the views are not consistent. In mammals, only a few sporadic reports have been reported on the systematic study of its macrophages. Zhang made dry
