Abstract

Tissue engineering knowledge is a step towards the treatment of irreversible damages to human beings. In the present study, PCL/Gel, PCL/Gel/nHA, PCL/Gel/Vit D3 and PCL/Gel/nHA/Vit D3 (Polycaprolactone/Gelatin/Nanohydroxyapatite/Vitamin D3) composite scaffolds were successfully constructed using electrospinning method. The proliferation and differentiation of hADSCs into the bone phenotype were determined using MTT method, ALP activity, Von Kossa and Alizarin red staining, and qRT-PCR test. The simultaneous presence of nHA and vitamin D3 led to the increased activity of ALP in the early stages (on the 14th day) and increased mineralization in the late stages (on the 21st day) in differentiated hADSCs. Further, it was found that the use of nHA and vitamin D3 resulted in increased expression of BGLAP and COLL I and reduced expression of ALP and RUNX2 in hADSCs for 21 days. The results indicated that nHA and vitamin D3 have a synergistic effect on the osteogenic differentiation of hADSCs. © 2018 Elsevier B.V.
