Production of Sertoli Cells
Once fully differentiated, the Sertoli cell is unable to proliferate. Therefore, once spermatogenesis has begun, no more Sertoli cells are created.
Recently however, some scientists have found a way to grow these cells outside of the body. This gives rise to the possibility of repairing some defects that cause male infertility.
It has been suggested that they may derive from mesonephros.

Famous quotes containing the words production of, production and/or cells:
“It is part of the educator’s responsibility to see equally to two things: First, that the problem grows out of the conditions of the experience being had in the present, and that it is within the range of the capacity of students; and, secondly, that it is such that it arouses in the learner an active quest for information and for production of new ideas. The new facts and new ideas thus obtained become the ground for further experiences in which new problems are presented.”
—John Dewey (1859–1952)
“... this dream that men shall cease to waste strength in competition and shall come to pool their powers of production is coming to pass all over the earth.”
