Sertoli cells What are tight junctions? proteins which link Sertoli cells together and separate the seminiferous tubules into the basal compartment and adluminal compartment Where is the basal compartment? nearer the basal lamina and blood vessels Where is the adluminal compartment? nearer the centre 1/2 What do tight junctions do? form a blood-testes barrier to prevent sperm cells from leaking into the blood stream and activating the immune system What are adherens junctions? proteins which mediate cell-cell adhesion Where are spermatogonium stem cells found? basal compartment What is the first thing that happens to they split into two identical daughter cells spermatogonium stem cells in spermatoduring mitosis genesis? What are the daughter cells produced from spermatogonium stem cells called? type A type B come back up to the basal lamina to What happens to type A daughter cells? become the next spermatogonium and continue replicating What happens to type B daughter cells? moves out of the basal compartment and into the adluminal compartment What allows type B daughter cells into the adluminal compartment? chemicals tell the Sertoli cells to open the tight junction and allow type B cells through 2/2
