Abstract
A biocompatible bone graft for implanting into a bone wound site or screening a bone disease drug, comprising a porous scaffold structure made from a tannin-hydroxyapatite resin, a population of osteocompetent stem cells, and a growth medium. Methods of synthesis and physical characterization of the porous scaffold structure are described, as well as biological testing of the osteocompetent stem cells of the bone graft.
