Scaffolds without growth factors were used for week 0 analysis. Values represented are averages + standard deviation of n = 3, P < 0.05.
a
Statistically significant difference from week 0 PLGA samples.
b
Statistically significant difference from the respective raw material supplemented group at week 0.
