The spermatogonial stem cell niche

Open access
De Rooij, Dirk G.·2009·Microscopy Research and Technique

Abstract

Spermatogonial stem cells (SSCs; A s spermatogonia) and their direct descendants (A pr and A al spermatogonia) are preferentially located in those areas of the seminiferous tubules that border on the interstitial tissue. Fewer of these cells are present in tubule areas directly bordering on another tubule. Therefore, the SSC niche is related to the presence of interstitial tissue. The somatic cells within the seminiferous tubules, the Sertoli cells, are able to produce growth factors that stimulate self‐renewal (GDNF, FGF2) and differentiation (activin A, BMP4, and SCF) of the SSCs. As Sertoli cells are everywhere on the basal membrane of the tubules, other factors coming from outside the tubules must determine, either directly or indirectly via Sertoli cells, whether in a particular area self‐renewal of SSCs will be preferred or differentiation in the form of A pr formation. Self‐renewal will be preferred in the stem cell niche and differentiation outside of the niche. Factors that could link the niche to the interstitial tissue are CSF1, produced by Leydig cells that stimulate stem cell proliferation and FSH, the concentration of which will be highest near blood vessels and that stimulates GDNF production by Sertoli cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
