Biological Influence of Nonswelling Microgels on Cartilage Induction of Mouse Adipose-Derived Stem Cells

Figure 6

The induction of chondrogenesis by the microgels was measured by RT-PCR. The expression of the housekeeping gene 18S was used to normalize all the other gene expression. Data represented mean  SD; Asterisks indicate statistical significance compared to TCP or PEI group (**Compared to TCP group, ; ##Compared to PEI group, ). The error bars indicate the standard deviations of three independent assays ().
