Tissue Engineering combines biology (tissue), with mechanics (engineering), to give us a functional substitute for all sorts of bodily responses. It most often combines some type of non-living material with living biological cells. These cells have usually been extracted, and multiplied in a growth-inducing medium. So instead of altering the interior of the cell, tissue engineering typically replicates or multiplies the cells. There are many applications already in development, with many more still yet to come. Some of the applications of current interest are nerve regeneration, structural tissue repair, artificial skin, new bone growth, artificial organs, and cornea replacements. It is not our intention to explain these applications in any kind of detail, but merely to inform you that they exist, and that it is a very exciting field, in which more than likely, we have just skimmed the surface as to what will ultimately be available. Hair Multiplication is an outgrowth of Tissue Engineering, in that hair cells are multiplied outside of the body, and then injected back into the scalp. |
