早期对哺乳动物小肠粘膜发育的描述，例如Hilton（1902）对大鼠的描述和Johnson（1910）对人类的描述，主要关注该器官的组织发生，而细胞学发育很少受到关注。另一方面，最近使用现代技术的研究仅限于相对有限的细胞学问题，忽略了更普遍的方面。因此，Behnke (1963 a, b) 研究了发育中的大鼠肠道中的核糖体和多核糖体； Overton & Shoup (1964) 观察到雏鸡刷状缘的自生； Moog (1961) 对细胞进行了组织化学检查。 Bonneville (1963) 和 van Lennep (1964) 对一般分化的唯一解释。本调查旨在对大鼠从妊娠第 13 天到出生期间空肠吸收上皮细胞的发育进行一般描述。
Early descriptions of the development of the mucous membranes of the mammalian small intestine, such as those of Hilton (1902) in the rat, and Johnson (1910) in the human, were largely concerned with the histogenesis of the organ, and cytological development received little attention. On the other hand recent investigations using modern techniques have been confined to relatively circumscribed cytological problems, ignoring the more general aspects. Thus ribosomes and polysomes in developing rat intestine have been studied by Behnke (1963 a, b); Overton & Shoup (1964) have observed the autogeny of the brush border in the chick; and Moog (1961) has examined the cells histochemically. The only accounts of general differentiation have been those of Bonneville (1963) and of van Lennep (1964). This survey aims to give a general description of the development of the jejunal absorptive epithelial cells in the rat, from the 13th day of pregnancy until birth.
