Abstract:

BACKGROUND: Adipose-derived mesenchymal stem cells are more appropriate as seed cells for cartilage induction in patients who have unsatisfied repair after articular cartilage injuries, but how to induce the cartilage function need to be studied.
OBJECTIVE: To induce the chondrogenic differentiation of human adipose-derived mesenchymal stem cell microspheres using three-dimensional culture system.
METHODS: Adipose tissues were extracted after liposuction under sterile, to isolate and culture human adipose-derived mesenchymal stem cells. The third passage cells were analyzed by flow cytometry and identified by osteogenic induction and adipogenic induction, and meanwhile, cells were cultured under three-dimensional culture system for chondrogenic differentiation. Then, cells were observed by Alcian blue staining for identification of glycosaminoglycan synthesis as well as hematoxylin-eosin staining for histological analysis. Expression of collagen type II was detected by immunofluorescence method. Cartilage stiffness was determined by mass measurement.
RESULTS AND CONCLUSION: Isolated human adipose-derived mesenchymal stem cells highly expressed CD105, CD44, CD29, but showed low expressions of CD45, CD34. After osteogenic and adipogenic induction, cells were positive for alizarin red staining and oil red O staining. Under the three-dimensional culture, chondrocytes could greatly express glycosaminoglycans and collagen type II. The results suggest that under the three-dimensional culture, human adipose-derived mesenchymal cells differentiate into chondrocytes and have the characteristics of chondrocytes.
