Abstract
The correct functioning of Sertoli cells (SCs) is pivotal for successful spermatogenesis. They are major targets for hormones, endocrine disruptors, and other substances that men are subjected to every day. One of the main SC functions that quickly responds to a deleterious stimulus is proliferation. This is directly related to the in vivo capacity of these cells to sustain a good number of developing germ cells. The protocols in this article can be tested on SCs of different origin. For the case of human SCs from small human testicular biopsies, a short and simple protocol to isolate and culture these cells is provided. The other protocols discussed herein represent two different procedures, somewhat complementary, to assess SC proliferation. In brief, the sulforhodamine B assay allows the investigator to dye healthy fixed SCs maintained in culture. In the MTT assay, on the other hand, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) is reduced by live SCs. These methods are mostly used to evaluate how SC proliferative activity responds to exposure to compounds such as toxicants or hormones. © 2019 by John Wiley & Sons, Inc.
