摘要: This study examined the effects of intermittent hydrostatic pressure (IHP) and transforming growth factor-β3 on chondrogenesis adult human mesenchymal stem cells (hMSCs) in vitro. Chondrogenic gene expression was determined by quantifying mRNA signal levels for SOX9, a transcription factor critical cartilage development matrix proteins, aggrecan type II collagen. Extracellular production weight histology. IHP applied to hMSCs pellet culture at level 10 MPa frequency 1 Hz 4 h per day periods 3, 7, 14 days. responded addition TGF-β3 (10 ng/mL) with greater than 10-fold increase (p < 0.01) each, collagen, during 14-day period. Applying presence further increased these proteins 1.9-, 3.3-, 1.6-fold, respectively, 14. were just exposure IHP. Extracellul...
