Figure 10. Schematic model of hyperproliferative crypt formation in Hsp60Δ/ΔIEC mice.

Figure 10

Intestinal crypts loose stem cells and the proliferative capacity in response to HSP60 loss. WNT-related factors are produced by HSP60-deficient IEC including Paneth cells to compensate diminished proliferation. This epithelial microenvironment causes HSP60-positive escaper stem cells to hyperproliferate and form HSP60-positive crypt nodules, finally leading to tissue reconstitution. In contrast, HSP60 deficiency in Lgr5-positive stem cells causes transient loss of stem cells without alterations in tissue morphology.
