Cyclic Tensile Strain Induces Tenogenic Differentiation of Tendon-Derived Stem Cells in Bioreactor Culture

Figure 3

Expression of type I collagen (a), tenascin-C (b), tenomodulin (c), and scleraxis (d) of TDSCs cultured in control group and different experimental groups for 7 days. The expression levels, quantified using real-time RT-PCR, were normalized to those of housekeeping gene (GADPH). TDSCs in the control group served as controls (the expression levels of tendon ECM genes were treated as 1 in this group). The data were expressed as mean ± SD. The samples indicated with asterisk () had a significant difference between experimental groups and control group () ().
