FORMATION OF APPENDICULAR LYMPHOID NODULES IN RABBITS IN PRENATAL AND EARLY POSTNATAL ONTOGENESIS

Аннотация

The research results show that the lymphoid nodules of the appendicular process of the rabbit embryo first appear on the 21-24th day of embryonic development in the form of clusters of mesenchyme under epithelial cells and dome-shaped eminences. After birth, the appearance of antigenic structures and the need for immune protection stimulates the formation of immune defense organs and immune structures of the body in postnatal ontogenesis.
