Abstract
This article presents a method for making highly porous biodegradable scaffold that may ultimately be used for tissue engineering. Poly(L‐lactic‐co‐ϵ‐caprolactone) acid (70∶30) (PLCL) scaffold was produced using the solvent casting/leaching out method, which entails dissolving the polymer and adding a porogen that is then leached out by immersing the scaffold in distillated water. Tensile tests were performed for three types of scaffolds, namely pre‐wetted, dried, and UV‐irradiated scaffolds and their mechanical properties were measured. The pre‐wetted PLCL scaffold possessed a modulus of elasticity 0.92±0.09 MPa, a tensile strength of 0.12±0.03 MPa and an ultimate strain of 23±5.3%. No significant differences in the modulus elasticity, tensile strength, nor ultimate strain were found between the pre‐wetted, dried, and UV irradiated scaffolds. The PLCL scaffold was seeded by human fibroblasts in order to evaluate its biocompatibility by Alamar blue® assays. After 10 days of culture, the scaffolds showed good biocompatibility and allowed cell proliferation. However, the fibroblasts stayed essentially at the surface. This study shows the possibility to use the PLCL scaffold in dynamic mechanical conditions for tissue engineering
