Silk fibroin material in a form of waterinsoluble film was used as a stabilization and sustained release matrix to incorporate neutraceuticals, such as curcumin from Curcuma longa. Curcumin release kinetics, distribution, and biological activities to regulate cell growth and differentiation were examined. It was found that curcumin was stably released at a low level for more than 4 weeks from silk matrix, which promoted adipogenic differentiation of human mesenchymal stem cells (hMSCs).
