As the sperm formation was not observed in vitro and also in severely damaged tubules, it might point to the significance of the well-preserved niche for the differentiation MSCs into sperm.
Together these effects are restrained by preserving the hypoxic niche (Figure 9).

Because composers did not write down their works, it was not until the first decades of the 20th century, when the nascent record industry identified Jewish immigrants as a niche market, that the sound of klezmer was preserved.
Several growth factor- and chemokine-receptors expressed by HSCs that bind soluble or membrane-bound ligands produced by niche cells have been shown to be crucial for inhibiting HSC division by retention within the niche, thus preserving their dormancy and progressive lost by exhaustion [ 13, 14].
We now find that the glial cell niche also preserves neuroblast proliferation under conditions of hypoxia and oxidative stress.
We have recently described a 3D culture system that allows long-term expansion of adult small intestine, stomach and liver cells without the need of a mesenchymal niche, while preserving the characteristics of the original adult epithelium (Sato et al, 2009; Barker et al, 2010; Huch et al, 2013).
