Effects of administration of conditioned medium from NormBM-MSC and IschBM-MSC on infarct volume and functional behavior in MCAo rats. (A) The right lateral view of MCAo rat brains showing the stroke outcome from different treatments, (B) The infarct volumes of MCAo rat brains evaluated at 7 days postinjury using TTC staining analysis (C) Quantitative results of TTC staining of MCAo rat brains from different treatment, These results were taken as the mean ± S.D. from 8 ~ 15 rats/group (Control n = 8, NormBM-MSC Cm n = 15, IschBM-MSC n = 9), (D) Grip strength of left forelimbs (g) assessed using grasping power test on stroke-affected side (#p < 0.05 versus pre-MCAo, *p < 0.05 versus Control), (E) Grip strength of right forelimbs (unaffected side). Data were given as the mean ± S.D. from 6 ~ 7 rats/group (7 rats for control, 6 rats for NormBM-MSC Cm and 6 rats for IschBM-MSC Cm).
