Figure 1 A Diagrammatic Representation of the Vascular/Interstitial Niche for the Undifferentiated Spermatogonia in Mouse Testes Portions of three neighboring seminiferous tubules (gray) are shown with the surface in contact with the vascular/interstitial zones shaded in light yellow. The interstitial space (yellow) contains the blood vessels (red) and interstitial cells (orange). The peritubular myoid cells (blue) surround the tubules, which contain undifferentiated type A spermatogonia (green), differentiated spermatogonia (violet), spermatocytes and spermatids (not colored), and Sertoli cells (tan).
