title: [Update of the researches on the niche for spermatogonial stem cells].
abstract: Spermatogonial stem cells are a population of immortal cells, capable of self-renewal and multi-directional differentiation. The theory of the "stem cell niche" was originally proposed for the hematopoietic system, and niches also exist in testicular tissues. The niche for spermatogonial stem cells is a semi-isolation system, characteristic of specific number regulation and changing with the age. The self-renewal of spermatogonial stem cells is regulated by two endogenous factors, nanos2 and Plzf, as well as by the niche cell-excreted factor, glial-derived neurotrophic factor (GDNF).
