tissue engineering is Biomaterials have been created to elicit specific cellular functions ,conduct tissue regeneration and support cell transplantation. This studies present to the fabrication of PVA based scaffold by salt leaching method. the result show Porosity of PVA scaffolds derived from calculating porosity,which porous size is depend on salt particle size and salt distribution in PVA solution ,if the salt particle has large size render to increase size porous of PVA scaffolds increasing as cause good properties suitability for tissue engineering application.
