5.Allogeneicversus heterogeneous bone marrow mesenchymal stem cells for laryngeal cartilage repair
Chinese Journal of Tissue Engineering Research 2016;20(7):966-971
BACKGROUND:Because chondrocytes have no regeneration ability, to select suitable seed cels is the primary problem to repair cartilage defects.
OBJECTIVE:To investigate the effect of alogeneicversus heterologous bone marrow mesenchymal stem cels (BMSCs) in repairing laryngeal cartilage defects after chondrogenic induction.
METHODS:BMSCs from human and rabbits were isolated and cultured. Passage 3 cels were cultured in chondrogenic induction medium containing transforming transforming growth factor beta 1 and bone morphogenetic protein, and then were dropped onto a poly(lactic-co-glycolic acid) (PLGA) scaffold. Thirty New Zealand rabbits were randomly assigned into three groups: blank control group, human BMSCs group, rabbit BMSCs group. Animal models of laryngeal cartilage defects were made in the three groups. After modeling, saline-soaked PLGA scaffold, PLAG scaffold with human BMSCs or with rabbit BMSCs were implanted respectively into the rabbits in the normal blank, human BMSCs and rabbit BMSCs groups. The expression of type II colagen in the larynx and its surrounding tissues was detected by immunohistochemistry at 4 and 8 weeks postoperatively.
RESULTS AND CONCLUSION: The animals in each group breathed normaly with no presence of wheezing, and their eating and activity were good. Moreover, there was no purulency or infection in the three groups. At 4 and 8 weeks after operation, the positive rates of type II colagen in the two BMSCs groups were significantly higher than that in the blank control group (P < 0.05). There was no significant difference between two BMSCs groups (P > 0.05). These results show that both alogeneic and heterologous BMSCs have good therapeutic effects on the repair of laryngeal cartilage defects in rabbits.
