Antiapoptotic signaling. Immunoblotting showed a significant increase in concentration of anti-apoptotic Bcl-2-associated death promoter (pBAD) in the hypoxia-conditioned extracellular vesicle group (HEV, n = 7) compared with saline control (CON, n = 6). Phospho-B-cell lymphoma 2 (pBcl-2) showed a trend towards an increase in HEV treatment, and B-cell lymphoma 2 (Bcl-2) was significantly decreased with HEV treatment compared to CON. This resulted in a significant increase in the pBcl-2 to BCL-2 ratio in the HEV group. Graphs represent data points with mean with standard deviation. Immunoblotting data are -fold change normalized to average control. Data points greater than 2 standard deviations from the mean are excluded from analysis.
