Not exact matches
Looking further into the intestinal crypts of both the transgenic and wild - type mice, the research team
made what they consider a surprising finding: Not only was HMGA1 causing the stem
cells themselves to self - renew or proliferate more rapidly in the transgenic animals, but it was also increasing the number of Paneth
cells, a type of
niche cell known to support intestinal stem
cells.
If these
niche cells can not
make Wnts, mice do not develop adult intestines, and if these
niche cells can not
make RSPO3, mice can not repair the intestine after injury.
Stem
cells are encapsulated into
niches made from materials designed to mimic the natural extracellular matrix.
In an earlier study, Jones had shown that the hub
cells secrete the self - renewal factor upd, which signals neighboring stem
cells to maintain stem
cell fate,
making hub
cells an essential component of the stem
cell niche.
