Coculture of NK-MSCs results in the inhibition of phosphorylation of NK cell Stat5. Protein lysates were produced identically to those in Figure 4. Protein lysates from NK-MSCs cocultured at 1:1 and varying ratios (B) were run in the Western blot. The data are representative of 3 independent experiments. β-Actin was used as an internal control to confirm equivalent protein loading.
