Abstract: © 2018 In this study, composite scaffolds consisting of mineral ion-loaded hydroxyapatite derived from fish scale (mHAFS) in a poly(lactic acid) (PLA)/chitosan (Chi) matrix (mHAFS@PLAChi) were fabricated by an in situ blending technique. Mineral ion loaded HAFS was successfully converted into mHAFS via the hydrothermal heating of HAFS in a SBF (simulated body fluid) solution. The composite mHAFS with PLAChi showed a compressive strength of 20 MPa and a compressive modulus of 539.88 MPa with a microporous structure. In vitro investigation showed that the UMR-106 cells adhered well and proliferated on the mHAFS@PLAChi surface. Most importantly it improved the cell viability and alkaline phosphate (ALP) activity. These findings suggest that these synthesized materials have great potential for use in bone tissue engineering.
