Morphology of P, PR, PT and PRT scaffolds degraded in vitro. (Scale bars: 50 μm in A–D, 10 μm in E–H. P: poly(d,l-lactic acid); PR: poly(d,l-lactic acid)/RGD peptide modification of poly{(lactic acid)-co-[(glycolic acid) -alt-(l-lysine)]}; PT: poly(d,l-lactic acid)/β-tricalcium phosphate; PRT: poly(d,l-lactic acid)/RGD peptide modification of poly{(lactic acid)-co-[(glycolic acid) -alt-(l-lysine)]}/β-tricalcium phosphate).
