Fig. 5From: Autologous mesenchymal stem cells or meniscal cells: what is the best cell source for regenerative meniscus treatment in an early osteoarthritis situation?Comparison of collagen II (Col2) ELISA results of aggregates from human meniscal cells (black) (three pellets at each time point of each patient (n = 14)) and mesenchymal stem cells (MSCs; gray) (three pellets at each time point of each patient (n = 6)) after 21 days of culture in chondrogenic media. Meniscal cells from non-refixable meniscal tears show no chondrogenic potential. *P < 0.005Back to article page
