Regeneration of mouse skeletal muscles which received control hADSCs or hADSCs pretreated with IL-4 and SDF-1. (A) Localization of CD45+, CD68+, or CD163+ cells in regenerating skeletal muscles which received control ADSCs or ADSC pretreated with IL-4 and SDF-1 assessed at day 7 of regeneration. CD45+, CD68+, and CD163+ cells (green), nuclei (blue), bar = 20 µm. (B) Expression of mRNAs encoding human CXCL2, CXCL14, IGFBP5, TGFb, CCL2, and BNDF. Expression was normalized to mRNA encoding HPRT. For each experimental group n ≥ 3. Data are presented as mean ± SD. Data have been analyzed using Kruskal-Wallis test.
