Reduction of grafted BM-MSC death by PRCR preconditioning in vivo. (A) Optical in vivo imaging showing enhanced intensity and durability of GFP signals in PRCR group (group 1) compared with control group (group 2). (B, C) Representative figures of TUNEL staining at day 7 showing that PRCR preconditioning before transplantation significantly reduced the number of TUNEL-positive grafted cells. (Scale bar=25 mm). (n=4), #P<0.01 versus group 1. (D) Quantification of the number of surviving grafted cells at 22 days after transplantation and injury. PRCR preconditioning significantly increased the survival of grafted MSCs (n=4); *P<0.05, #P<0.01, &P<0.001 versus group 1.
