We aimed to explore the mechanism by how LX4211 affects bone marrow mesenchymal stem cells (BMSCs) during ischemia-reperfusion (I/R). BMSCs were extracted and treated with LX4211 followed by analysis of cell proliferation and migration by CCK-8, Transwell assay and wound healing tests, cell apoptosis and cycle by flow cytometry, exosomes and VEGFA secretion by immunoenzyme-linked adsorption. BMSCs treated with LX4211 or DMSO were administrated into mice with blood perfusion and capillary or arteriolar density was detected. Treatment with LX4211 significantly inhibited BMSCs proliferation, increased apoptosis and activated AMPK/ACC signaling along with reduced the number of exosomes and VEGFA level and impaired physiological functions. In vivo experiments determined that LX4211 alleviated I/R of lower limbs by inhibiting the muscle retention of BMSCs and paracrine. In conclusion, LX4211 treatment can delay the blood recovery of ischemic non-diabetic mice by reducing the proliferation, migration and impairing paracrine of BMSCs.
