Aggrecan is an integral component of the extracellular matrix in cartilaginous tissues, including the growth plate. Heterozygous defects in the aggrecan gene have been identified as a cause of autosomal dominant short stature, bone age acceleration, and premature growth cessation. The mechanisms accounting for this phenotype remain unknown. We used ATDC5 cells, an established model of chondrogenesis, to evaluate the effects of aggrecan deficiency. ATDC5 aggrecan knockdown cell lines (AggKD) were generated using lentiviral shRNA transduction particles. Cells were stimulated with insulin/transferrin/selenium for up to 21 days to induce chondrogenesis. Control ATDC5 cells showed induction of Col2a1 starting at day 8 and induction of Col10a1 starting at day 12. AggKD cells had significantly reduced expression of Col2a1 and Col10a1 (p |
