Human Fetal Chondrocytes

Description

Human Fetal Chondrocytes are primary cells isolated from healthy human fetal cartilage tissue. As primary cells, they exhibit limited proliferative capacity and are not suitable for long-term passaging. As the principal cell type in cartilage, fetal chondrocytes play a critical role in cartilage development, growth, and extracellular matrix production. In monolayer culture, they undergo de-differentiation into a fibroblast-like phenotype, which can be reversed in semi-solid gels. These cells exhibit the typical polygonal morphology of chondrocytes and express key cartilage-specific markers including collagen type II, aggrecan, and SOX9. Their clonal growth is strongly stimulated by IGF-I and IGF-II, but not by insulin or growth hormone. Due to their high proliferative capacity and enhanced matrix synthesis compared to adult chondrocytes, they are valuable for studying cartilage formation, repair, and developmental biology. These cells are important in research on cartilage-related diseases such as osteoarthritis and congenital cartilage defects.
