| 摘要 |
This invention relates to a porous ceramic sphere comprising a particulate micro-porous bioinert material, in the form of spheres or scaffolds, having interconnected pores. Pores on the surface of each sphere are connected to pores inside such sphere via blow-holes and the internal pores are in turn interconnected, so that in addition to a high porosity, the spheres have a high permeability to gas and liquid, thus contributing to the creation of an artificial vascular system in which cells will proliferate, migrate and differentiate into the specific tissue while secreting the extracellular matrix components required to create the 3D tissue and organs.
