Fig. 4From: Chondrogenic induction of mesenchymal stromal/stem cells from Wharton’s jelly embedded in alginate hydrogel and without added growth factor: an alternative stem cell source for cartilage tissue engineeringRelative expression of specific cartilage-related genes evaluated by quantitative RT-PCR during 28 days of chondrogenic induction. All results are expressed as mean ± standard error of the mean (n ≥ 3). *p < 0.05, **p < 0.01 and ***p < 0.001, day x vs day 3 for a same cell source. ### p < 0.001, WJ-MSC vs BM-MSC for a same culture time.
