OBJECTIVETo observe the effect of transplantation of allogeneic adipose-derived stem cells (ADSCs) on serum biochemical indicators and sporting ability in highly endurance-trained rats from a fasciological perspective.

METHODSThe ADSCs were cultured in vitro. Forty male Wistar rats were randomized into 4 equal groups, namely the blank control group, overtraining (model) group, transplantation without training group and overtraining plus transplantation group. The rats in the two overtraining groups were subjected to exhaustive swimming for 1 week, and in the two transplantation groups, cultured allogeneic ADSCs (2×10(6)/ml) were injected via the tail vein. The exhaustion time in swimming and the serum levels of BUN, LDH, BLa, and Hb of the rats were recorded after the treatments.

RESULTSThe rats in the model group showed significantly increased serum BUN, LDH and BLa levels and decreased Hb level with a extended exhaustion time as compared with those in the blank control group (P<0.01). The BUN, LDH and BLa was significantly lower, Hb level higher and the exhaustion time significantly longer in the overtraining plus transplantation group than those in the model group (P<0.01).

CONCLUSIONSADSCs can effectively prolong the exhaustion time of rats during exhaustive swimming and enhance their sporting ability.
