  • ComparisonofEnzymaticandNonEnzymaticMeans3

    MTT Assay on Reattached CellsAs seen in Fig. 2 , the proportion of viable MSC that re-attached was significantly higher (p = 0.0004) upon dissociation with trypsin (82.1% ± 2.0%) compared to enzyme-free dissociation buffer (5.0% ± 0.2%). The same trend was observed after the dissociated MSC were subjected to freeze–thawing (68.4% ± 3.8% versus 2.8% ± 0.4%, respectively, p = 0.002......閱讀全文
