Consistent with previous findings [10, 11], BM-MSC improved poststroke survival (Fig. S1D), enhanced neurological (Fig. S1E), reduced cerebral infarct volume (Fig. S1F), preserved white matter integrity (MBP staining, Fig. S1G), and mitigated inflammatory cell infiltration (Fig. S2). The gene discussed is MBP; the disease is brain infarction.
