FIG. 3.
Chondrocyte characterization using flow cytometry following passage 1. Chondrocytes cultured in hPL either in the Quantum bioreactor or on TCP were not differentially immunopositive for chondropotency or MSC markers. CD49a was higher following culture in hPL on TCP cf. in the Quantum® bioreactor (p < 0.05; paired t-test). Chondrocytes cultured on TCP in either hPL or FBS were not differentially immunopositive for chondropotency or MSC markers. Immunopositivity for CD49b, CD49c, and CD151/61 was higher following culture in hPL cf. FBS on TCP (p < 0.05; paired t-test). MSC, mesenchymal stromal cell.
