The gastrointestinal tract (GIT) is a complex system, which changes in response to requirements of the body. GIT represents a barrier to the external environment. To achieve this, epithelial cells must renew rapidly. This renewal of epithelial cells starts in the fetal life under the influence of many GIT peptides by swallowing amniotic fluid (AF). Development and maturation of GIT is a very complex cascade that begins long before birth and continues during infancy and childhood by breast-feeding. Many factors like genetic preprogramming, local and systemic endocrine secretions and many trophic factors (TF) from swallowed AF contribute and modulate the development and growth of the GIT. GIT morphogenesis, differentiation and functional development depend on the activity of various TF in the AF. This manuscript will review the role of AF borne TF in the development of GIT.
胃肠道(GIT)是一个复杂的系统,会根据身体需求发生变化。胃肠道是对外界环境的一道屏障。为实现这一功能,上皮细胞必须快速更新。上皮细胞的这种更新始于胎儿期,在许多胃肠道肽的影响下,通过吞咽羊水(AF)来完成。胃肠道的发育和成熟是一个非常复杂的级联过程,早在出生前就开始了,并在婴儿期和儿童期通过母乳喂养持续进行。许多因素,如基因预编程、局部和全身内分泌分泌以及来自吞咽羊水的许多营养因子(TF),都对胃肠道的发育和生长起到促进和调节作用。胃肠道的形态发生、分化和功能发育取决于羊水中各种营养因子的活性。本手稿将综述羊水中携带的营养因子在胃肠道发育中的作用。
