Abstract

The invention provides a three dimensional (3D), porous, biodegradable and biocompatible tissue engineering scaffold, wherein at least 25% w/w of the scaffold is particulate egg shell membrane (ESM) distributed substantially uniformly therein and the scaffold is essentially dry. Methods for preparing the same by freeze-drying and cryogelation and the use thereof in methods of tissue engineering and to promote the healing of wounds are also provided.
