C1q/tumor necrosis factor-related protein-3-engineered mesenchymal stromal cells attenuate cardiac impairment in mice with myocardial infarction

a, b Surface marker molecules expressed in passage 4 MSCs were analyzed by flow cytometry and quantified by image analysis of positive cells. Data are means？±？SEMs (n？=？4). c Representative image of MSCs morphology (passage 4) and multilineage differentiation capacity into osteoblasts and adipocytes, Images were at original magnification, ×100. d RT-PCR was used to evaluate CTRP3 mRNA levels in MSCs exposed to serum deprivation and hypoxia (n？=？4). e, f Western blotting and quantification of CTRP3 in MSCs (n？=？6). g RT-PCR analysis for MSCs treated with serum deprivation plus 400？μM H2O2 for 24？h (n？=？4). h Western blotting and quantification of CTRP3 in MSCs cell lysates (n？=？6). i Western blots and quantification of CTRP3 in conditioned medium (CM) from MSCs treated with serum deprivation plus H2O2 (n？=？5). Data are means？±？SEMs. *P？<？0.05; **P？<？0.01; ***P？<？0.001 versus the contro
