FIG. 3.
nLacZ+ cells among C + MDSC and C + MDSC + TM groups. (A) After 5 weeks, the C + MDSC + TM group showed a significant increase in the number of nLacZ+ cells when compared with the C + MDSC group. *Significantly different when compared with C + MDSC 5 weeks (p = 0.02). ΦSignificantly different when compared with C + MDSC and C + MDSC + TM 1 week (p = 0.00 and 0.01, respectively). (B) Schematic representation of nLacZ+ cell distribution in four MDSC transplanted groups. (C) Histological representation of nLacZ+ cells (blue) in contused muscle tissue (20 × objective). c, contusion; nLacZ, nuclear-localized LacZ; TM, treadmill. (Insets represent 10 × magnification).
