Notes: Vin = vinculin; OP = osteopontin; Col I = type I collagen; (0) = not significantly different than TCPS; (−) = significantly lower than TCPS; (+) = significantly higher than TCPS; (−−) = much lower than TCPS; (++) = much higher than TCPS; 0/−, 0/+ = modestly lower or higher.

^*: p < 0.05;

^**: p < 0.01, respectively. Integrin and Vin was measured by immunoblotting. OP and Col I measured by RT PCR.
