Bone tissue engineering is a rapidly developing area. This form of therapy differs from standard drug therapy or permanent implants in that the engineered bone becomes integrated within the patient, affording a potentially permanent and specific cure of the disease state. The problem with putting man-made materials in the body is that they are subject to fatigue, fracture, toxicity, and wear, and do not remodel with time. In tissue engineering for the bones, you make the cells in a culture and then place them into the patient. Cells in the body are constantly receiving mechanical, electrical, structural and chemical cues to what they should be doing. So it is important to place the cell in back into the body so that can get the cures so go in the shape and form that they are needed to be in. Bone tissue engineering can possibly for a substitute in the bone instead of using man made materials.
