Differences in soluble receptor secretion by ex-vivo expanded stromal cell populations. BMSC-CM and ASC-CM was concentrated 25-fold, to a formulation that represented the collection of 2x106 cells per ml of CM. Control samples are basal media that was not conditioned by cells. Shown are ELISA analysis of CM for soluble receptors, including (a) sTNFR1, (b) sVEGFR1, (c) sTNFR2 and (d) sVEGFR2. There was non-specificity of the sVEGFR2 antibody pair when analyzing CM samples. BMSCs uniquely expressed high levels of sTNFR1 and sVEGFR1.
