Figure 1.
Flow cytometry analysis of human chondrocytes (HCH). After the identification of single cells by exclusion of debris (upper-left panel), staining for chondrocyte (CD44, CD73, CD90 and CD105) markers confirmed cell identity. Bone marrow stromal cell-specific (CD271) marker resulted negative, confirming absence of subchondral bone marrow contamination. Absence of hemato-endothelial (CD31, CD34, and CD45) markers staining further supported HCH identity. Representative plots are shown, unstained in black and stained in red.
