Abstract
Recently, the new interdisciplinary studies of the tissue engineering are progressing remarkably. These technologies are expected as a breakthrough to overcome the defects and the disadvantages of artificial organs and organ transplantations.
The strategy of the tissue engineering is divided to two groups. One is the in vitro method, and the other is in vivo method.
In the in vitro method, the living cells are picked out and cultured to make some tissues and organs. After that, the tissue or organs are implanted into patient's body.
In the in vivo method, the extracellural matrix which cells can use to make their own environment is settled in the internal body. At that time the stem cells, the precursor cells, and the DDS of cell growth factors to acceralate the growth speed are administrated into the artificial extracellural matrix. Regeneration of almost all of the tissues and organs have already been studied and some of them are tried to apply in clinical patients.
Applying this new technology, the medical therapy will be able to progress and change the thought of the medical therapeutology.
