Between the tubules are strands of interstitial cells. superimposed over one another. The lumen is in all tubes distinct and relatively large. The lining epithelium, or the seminal cells, differ in the adult in ditferent tubules, and even in different parts of the same tubule, being dependent on the state of secretion. 324. Before puberty all tubules are uniform in this respect, being lined with two or three layers of polyhedral epithelial cells, each with a spherical.
