CD146 on focal osteochondral samples from DL and OCD. (a) Representative CD146 immunostained section of focal osteochondral lesion from DL and OCD. Bars 100 μm. (b) Percentage of CD146-positive cells in cartilage and bone compartment of DL (number of fragments/sections = 21/21) and OCD (number of fragments/sections = 22/22). Data are expressed as median with 10th–90th percentile (whiskers). . (c) Percentage of CD146-positive cells in cartilage associated with histological score level (low, medium, and high). Data are expressed as median with 10th–90th percentile (whiskers). n.s. = not significant; ND = not detected. (d) Percentage of CD146-positive cells in bone associated with histological score level (low, medium, and high). Data are expressed as median with 10th–90th percentile (whiskers). ; n.s. = not significant.
