Abstract (original English)
Type II collagen is reported to have the capability of guiding adipose-derived stem cells (ADSCs) to differentiate towards a nucleus pulposus (NP)-like phenotype. So this study aimed to establish a three-dimensional (3D) collagen scaffold using N,N-(3-dimethylaminopropyl)-N'-ethyl carbodiimide and N-hydroxysuccinimide (EDAC/NHS) to increase the efficiency of ADSC differentiation into NP-like cells. Physical properties, such as porosity, biodegradation, and microstructure, and biological characteristics such as cytotoxicity, cell proliferation, and expression of relevant genes and proteins were measured to evaluate the efficacy of different scaffolds. Collagen scaffolds cross-linked with EDAC/NHS exhibited higher biological stability, better spatial structure, and higher gene and protein expression of functional markers such as aggrecan, SOX9 and COL2 than those of other groups. Based on the results, freeze-dried type II collagen cross-linked with EDAC/NHS formed the best 3D scaffold, for inducing ADSC proliferation and differentiation toward a NP-like phenotype. © 2016 Wiley Periodicals, Inc.
