Fig. 5. Humoral immune responses against injected human MSCs in C57BL/6 mice. Mice were injected twice with naïve hUC-MSCs or hAd-MSCs on days 1 and 31, and blood samples were drawn on day 38. (A) Sera were obtained and subjected to ELISA for total Ig and each Ig isotype. (B) hUC-MSCs or hAd-MSCs were stained with the sera from mice injected with hUC-MSCs or hAd-MSCs, respectively, and subjected to flow cytometric analysis. *p<0.05 and **p<0.01 vs. the control.
