Tissue engineering involves using cells, biomaterials as scaffolds, and signaling molecules to create living tissues and organs. It can be used to repair or replace damaged tissues like bone, cartilage, blood vessels, skin, and bladder. The goal is also to produce better organs for transplantation. Biomaterials serve as scaffolds that encourage cell growth and tissue regeneration by providing a structure similar to the body's native extracellular matrix. Cells, scaffolds, and signaling molecules are the key components in tissue engineering.

2.  The process of creating living, physiological, three
dimensional tissues and organs utilizing specific
combinations of cells, cell scaffold and cell signals, both
chemical and mechanical.
(OR)
 Tissue engineering covers the wide range of applications
that repairs or replace the portion of damaged tissues like
bone, cartilage, blood vessels, skin and bladder.
 Producing better organ used for transplantation.

3.  Biomaterials serve as an integral component of tissue
engineering.
 They are designed to provide architectural
framework reminiscent of native extracellular
matrix in order to encourage cell growth and
eventual tissue regeneration.

4.  To induce cellular migration or tissue regeneration
 To encapsulate cells and act as an immuno- isolation
barrier
 To provide a matrix to support cell growth and cell
organization.

5.  Cells- by means of stem cell culture.
 Scaffold- metals, ceramics, polymer
◦ Growth and development of cells provides mechanical
strength. Scaffold is of 2 types,
 Synthetic scaffold,
 Natural scaffold.
 Signaling molecules- growth factors, hormones,
morphogenetic proteins
