Growth factors and wound healing.

If one looks at the development of most drugs, it becomes evident that an extended period of time is necessary before the proper use and full range of activities of the drug in treating human disease become apparent. In many cases, initial treatment failures are due to faulty expectations as well as inadequate dosing and delivery systems. It is my opinion that growth factor therapy will follow a similar course but that it ultimately will have a role in the modulation of wound repair.
