Ingression or immigration is a cell movement of gastrulation and thus constitutes an embryonic developmental step. In this process, cells of the prospective endoderm, i.e., those of the outer cotyledon, migrate into the blastula. Errors in cell movements during the early development of the cotyledons lead to miscarriage in most cases. What is ingression? Ingression … Ingression: Function, Tasks, Role & Diseases
Epiboly is a cell movement of gastrulation that corresponds in principle to invagination. In this process, the prospective endoderm is overgrown by the prospective ectoderm. Disturbances of epiboly occur, for example, when there is a loss of function of the molecule fibronectin and can cause miscarriage. What is epiboly? Epiboly is a cell movement of … Epiboly: Function, Tasks, Role & Diseases
Theca cell is a type of connective tissue and is found in the ovarian follicle, where it plays important roles in follicle maturation. Under the influence of LH, the cells become thecalutein cells through luteinization, as they are in the corpus luteum. Theca cell tumors and granulosa theca cell tumors are the best known diseases … Theca Cell: Structure, Function & Diseases
A transdetermination in biology represents the reprogramming of a differentiated somatic cell. In general, the process of differentiation of somatic cells from the fertilized egg to the fully formed organism is irreversible. However, under certain conditions, a cell determined in its differentiation can be reprogrammed. What is transdetermination? In general, the process of differentiation of … Transdetermination: Function, Tasks, Role & Diseases
