|Bone marrow-derived cells can acquire renal stem cells properties and ameliorate ischemia-reperfusion induced acute renal injury.|
; Background: Bone marrow (BM) stem cells have been reported to contribute to tissue repair after kidney injury
model. However, there is no direct evidence so far that BM cells can trans-differentiate into renal stem cells.
Methods: To investigate whether BM stem cells contribute to repopulate the renal stem cell pool, we transplanted
BM cells from transgenic mice, expressing enhanced green fluorescent protein (EGFP) into wild-type irradiated
recipients. Following hematological reconstitution and ischemia-reperfusion (I/R), Sca-1 and c-Kit positive renal stem
cells in kidney were evaluated by immunostaining and flow cytometry analysis. Moreover, granulocyte colony
stimulating factor (G-CSF) was administrated to further explore if G-CSF can mobilize BM cells and enhance transdifferentiation efficiency of BM cells into renal stem cells.
Results: BM-derived cells can contribute to the Sca-1+ or c-Kit+ renal progenitor cells population, although most
renal stem cells came from indigenous cells. Furthermore, G-CSF administration nearly doubled the frequency of
Sca-1+ BM-derived renal stem cells and increased capillary density of I/R injured kidneys.
Conclusions: These findings indicate that BM derived stem cells can give rise to cells that share properties of renal
resident stem cell. Moreover, G-CSF mobilization can enhance this effect.
