FIG. 6.

Biochemical analysis of sGAG deposition and DNA content in (A) MSC and (B) NC pellets, cultured for 14 and 21 days in the three conditions tested: BM (white bars), chondrogenic (CM, bars with dots), or CM supplemented with γ-PGA (CM+γ-PGA, bars with stripes). Results are represented as box plots (MSC: eight pellets/condition, three independent donors; NC: five pellets/condition, three independent donors). Statistical significance was set at *p<0.05, (**p<0.025), using the Friedman paired test followed by the Dunn's multiple comparison post-test.
