The suppoing cells of the testes are the following:
All cells of the spermatogenic lineage are closely associated with the extended surfaces of Seoli cells and depend on them for metabolic and physical suppo. Each Seoli cell suppos 30 to 50 developing germ cells. Impoant in Seoli cell function are elaborate tight occluding junctions between their basolateral membranes that form a blood-testis barrier within the seminiferous epithelium. Ref: Mescher A.L.
