Physical Properties and Biocompatibility of a Core-Sheath Structure Composite Scaffold for Bone Tissue Engineering In Vitro
Figure 1
(a and b) Morphological comparison observation by SEM of the core-sheath structure composite scaffold and the PLGA/β-TCP skeleton (×50,50). (c and e) Magnified view of the white rectangle frame from (a) (×90,150). Note: the arrows point to the collagen wrapped the PLGA/β-TCP. (d and f) Magnified view of the white rectangle frame from (b) (×100,150). (g) Morphological observation by SEM of the core-sheath structure composite scaffold (×1 k). Note: the arrows point to the interface of the PLGA/β-TCP and the collagen. (h) Morphological observation by SEM of the PLGA/β-TCP skeleton. (×1 k).
