Useful notes on the Origin of Primordial Germ Cells ! Gametogenesis is arbitrarily designated as the first stage of embryonic development. In embryology, the gametes are usually discussed first, as they provide both the blue print and the raw material from which the embryo is formed. Gametogenesis i.e. formation of gametes in the sexes is tailored to their future roles [...]
Read this article to get information on Immunoglobulins , it’s structure and classes! Antibodies are specific glycoproteins produced by В-cells and constitute main components of humoral immunity. Antigen or immunogen present in the foreign body (microorganism or parasite) are mainly protein molecules which are responsible for the production of specific antibody or immunoglobin in the host. Some antigen molecules have [...]
Spermatogenesis: Notes on Spermatogenesis! Mammalian spermatogenesis is a highly synchronized, regular, long and extremely complex process of cellular differentiation by which a spermatogonial “stem-cell” is gradually transformed into a highly differentiated haploid cell ‘Spermatozoon.” This differentiation involves three distinct classes of germinal cells—the spermatogonia, the spermatocytes, and the spermatids, which usually are arranged in concentric layers in the seminiferous tubules.
