Pellet cultures with cells from immature and mature cartilage.
Pellet cultures were performed with cells from immature and mature bovine cartilage (n=12) and collected after 2 and 14 days and stained with safranin O (A–D) and STRO-1 (E–H). Pellets with immature chondrocytes showed stronger staining with safranin O and contained more STRO-1+ cells (B, F) as compared to pellets composed chondrocytes from mature cartilage (D, H). Bar = 100µm in large and 25µm in small images.
