Tissue Engineering and Regenerative Medicine
Tissue engineering is emerging as a significant potential alternative or complementary solution, whereby tissue and organ failure is addressed by implanting natural, synthetic, or semisynthetic tissue and organ mimics that are fully functional from the start or that grow into the required functionality. Initial efforts have focused on skin equivalents for treating burns, but an increasing number of tissue types are now being engineered, as well as biomaterials and scaffolds used as delivery systems. A variety of approaches are used to coax differentiated or undifferentiated cells, such as stem cells, into the desired cell type. Notable results include tissue-engineered bone, blood vessels, liver, muscle, and even nerve conduits.
Regeneration is the process of renewal, restoration, and growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. Every species is capable of regeneration, from bacteria to humans. Regeneration can either be complete where the new tissue is the same as the lost tissue, or incomplete where after the necrotic tissue comes fibrosis. Now a day its market is quiet high.
