摘要: Tissue engineering may be defined as the science of persuading body to heal or repair tissues that do not so spontaneously. This is a relative new and exciting field has experienced tremendous growth in past decade. In our current understanding, which developed over 10-15 years research, most common strategy for tissue fill defect with spongelike highly porous material. sponge scaffold carry cells and/or biomolecular entities such factors. Needless say, then critical regeneration process because it provides threedimensional framework attach produce extracellular matrix form tissue. As basic foundation this approach, its various properties need carefully designed optimized. an earlier paper we have outlined essential [1]. Briefly, should:
