that have the ability to produce the needed cell products to the desired area of the body where therapy is needed. This application can also be used in wound healing, where increased numbers of fibroblasts and keratinocytes aid in wound re-granularization, thus decreasing overall healing time. In regard to prosthetics, making the prosthetic device incorporate successfully with the tissue is a challenge. When the prosthetic’s surface is coated with haptotactic materials, the prosthetic is aided in forming covalent bonds with the cells and becomes securely attached to the cell layer. While haptotaxis may not be occurring in this process, it demonstrates the diversity with which this knowledge about haptotaxis can be used.
