Fig. 5From: Chm-1 gene-modified bone marrow mesenchymal stem cells maintain the chondrogenic phenotype of tissue-engineered cartilageNumber of vessels in the specimens 1 month and 2 months post transplantation were statistically analyzed: a chondrocyte–coral composites; b chondrocytes and MSCs coseeded into natural coral scaffolds in a ratio of 1:1; c MSC–coral composites; and d T-MSC–coral composites. Vascular numbers of each specimen were counted per time point as the mean ± SD. Each bar represented four specimens (*P < 0.05)Back to article page
