| Abstract: | Implantation growth of nephrogenic tissue of a 17-day rat embryo and of the epithelium from the nephron of animals aged 1 month was compared. Nephrogenic tissue in implantsin vivo showed appearances characteristic of its histogenesis. The tubular epithelium from the nephron of month-old animals showed manifestations of tissue growth and formed atypical kidney structures, reflecting its ability to undergo tissue and organotypical differentiation. It is concluded that the epithelium of the renal nephron has a wide range of reactive and plastic properties and is capable of organotypical determination.Department of Histology and Embryology, Tyumen' Medical Institute.
