Figure Legend:
E results for cell-seeded nonwoven 50:50 PGA/PLLA scaffolds plotted versus collagen concentration (mean±SEM, n=6) (a). Adapted from Engelmayr (see Ref. ) with permission by Elsevier Inc. Structural model predicted dependence of E on the fiber interbond arc length (b). Note that as the number of rigidly bonded fiber-fiber cross-over points increases (such as with P4HB dip coating or collagen accretion), the fiber interbond arc length decreases and the fiber effective stiffness (Ef)′ increases. Values of E for unseeded (short dashed line) and 9-week mesenchymal stem cell-seeded (long dashed line) nonwoven 50:50 PGA/PLLA scaffolds are indicated for comparison.
