Fig. 5. Effect of RGD-alg gel elastic moduli on TPC gene expression.

Fig. 5

Tendon marker genes expressed by 10 M/mL HH 37 TPCs cultured in RGD-alg gels for 7 days. RGD-alg gels of nanoscale elastic moduli from 3.4 to 20.1 kPa represented embryonic tendon from < HH 28 to HH 43. Elastic modulus significantly influenced the expression of (A) scleraxis, (C) Col I, and (E) Col XII, but did not significantly influence expression of (B) tenomodulin or (D) Col III. n = 6 gels per condition; * p < 0.05; ** p < 0.01; *** p < 0.001.
