Enhanced adipose mesenchymal stem cells proliferation by carboxymethyl-chitosan functionalized polycaprolactone nanofiber

Abstract

Background: Through combining two synthetic and natural polymers, scaffolds can be developed for tissue engineering and regenerative medicine purposes. Methods: In this work, CMC (20%) was grafted to PCL nanofibers using the cold atmospheric plasma of helium. The PCL scaffolds were exposed to CAP, and functional groups were developed on the PCL surface. Results: The results of FTIR confirmed CMC (20%) graft on PCL scaffold. The MTT assay showed a significant enhancement (p < 0.05) in the cell affinity and proliferation of ADSCs to CMC20%-graft-PCL scaffolds. After 14 days, bone differentiation was affirmed through alizarin red and calcium depositions. Conclusion: Based on the results, the CMC20%-graft-PCL can support the proliferation of ADSCs and induce the differentiation into bone with longer culture time.
