Pellet size of chondrogenic induced cells. Box plot showing pellet size (µm) of chondrogenic induced bone marrow (BM)- and adipose tissue (AT)-derived mesenchymal stromal cells and dermal fibroblasts (DF) in five different age groups (n = 4, N = 60). All pellets were generated from 5 × 105 cells and cultured in chondrogenic induction medium for 21 days. Cell types within the same age group not labeled with the same letter are significantly different from each other (p < 0.05)
