Higher number of residual hMSCs is quantitated from the parenchyma of BALB/c nude mice at Day 7. (A) Via IHC staining, STEM121-positive cells are identified as brown signals from representative tissue sections of both C57BL/6 (n = 5) and BALB/c nude mice (n = 5). (B) The number of residual hMSCs persisting in the parenchyma of both C57BL/6 (n = 5) and BALB/c nude mice (n = 5) is assessed via ALU qPCR. MSC persistence is higher in BALB/c nude mice. Statistical significance is defined as **P < 0.01 vs. C57BL/6 mice; mean ± SEM (t-test). Scale bar = 50 µm.
