Figure 4. Mechanical testing of random and aligned ES PLA scaffolds.

Figure 4

(A) Young’s modulus (MPa) for random, aligned (along fiber orientation), and perpendicular to fiber orientation. (B) Young’s modulus (MPa) of random & aligned electrospun PLA scaffolds over time in culture with or without cells (one week and three weeks). (C) Stress/strain curve for each condition and (D) random PLA scaffold. (E) aligned PLA scaffold (F) perpendicular oriented PLA scaffold. (G) Ultimate stress readings (MPa) for each condition. (H) Ultimate stress (MPa) for random & aligned electrospun PLA scaffolds over time in culture with or without cells (one week and three weeks).
