Figure 2

Fluorescent image of chondrocytes dyed with Fluo-8 AM in cartilage explant cultured in (A) chemically defined serum-free medium and (B) serum-supplemented medium. (C) Cell density (/mm2) in two different medium groups based on fluorescent calcium images of all samples. No significant difference was detected between two groups at the same time point. Cell density in both groups decreased with culture time (Mann-Kendall test, confidence factor > 95%).
