The main goal of this study was a comparison of biological properties of mesenchymal stromal cells (MSCs) obtained from bone marrow, adipose tissue and umbilical cord with respect to articular cartilage regeneration. MSCs were isolated and expanded in vitro up to the third passage. The kinetics of proliferation was analyzed by cell analyzer CEDEX XS and expression of selected markers was assessed by flow cytometry. The morphology was analyzed by inverted microscope and TEM. Pellet culture system and chondrogenic medium containing TGF-β1 was used to induce chondrogenic differentiation. Chondrogenesis was analyzed by real-time PCR; the expression of collagen type I and type II was compared. MSCs from all sources showed similar kinetics of proliferation and shared expression of CD73, CD90 and CD105; and were negative for CD14, CD20, CD34 and CD45. Observation under inverted microscope and TEM showed similar morphology of all analyzed MSCs. Cells from all sources underwent chondrogenic differentiation - they expressed collagen type II and acid mucopolysaccharides typical for hyaline cartilage. On the basis of obtained results it should be emphasized that MSCs from bone marrow, adipose tissue and umbilical cord share biological properties. They possess the chondrogenic potential and may be utilized in cartilage tissue engineering.
