Morphology and adhesion proportion of human synovial MSCs 10 min after placement on the porcine meniscus. a SEM images. b Proportion of cells adhered to the meniscus. Six cylindrical menisci were examined once per donor, and the results from five donors are shown independently. The proportion of adhering cells was 33 ± 3% for the cultured MSCs and 36 ± 3% for the thawed MSCs. *;p < 0.05 by paired t-test. c Association between the proportion of adhered cells and the proportion of cells with microspikes in suspension
