The TV news media is reporting the latest “break-through” in cosmetic medicine science. Evidently for a mere $4,000 one can take a punch biopsy of a patient’s skin, send it to a lab where fibroblasts are isolated, cultured and expanded. This results in millions of fibroblasts which are then re-injected into the face to rejuvenate the tissues as fibroblasts are known to synthesize the protein collagen which is lost in the aging face. This clearly is a break-through in cell biology albeit an expensive one and not a popular alternative since it doesn’t last longer than 6 months.
A different technology has been available for several years and achieves pretty much the same thing at a fraction of the cost, and it lasts forever. Adipose derived stem cells are isolated from liposuction aspirate and then re-introduced into the areas requiring rejuvenation. The stem cells are more basic precursor cells to fibroblasts thus are thought to transform into fibroblasts as well as other cell types that increase vascularity and provide many of the trophic growth factors that help rejuvenate skin. Depending on their environment, stem cells can be encouraged to form cartilage, even re-create osteoblasts that form bones. Therefore, stem cells have been used for a wide variety of clinical problems including skin rejuvenation, joint cartilage re-growth and healing, wound healing and even re-growth of cardiac muscle tissue.
All of these new technologies whether or not they are “FDA approved” need to be evaluated through the prism of overall scientific advances. It seems that the imprimatur of the FDA allows the science to be exploited for marketing gain by the few. Regardless, FDA involvement with these new scientific advances has not been well defined and tends to allow for marketing adulteration of the product in question often misleading the consumer regarding other available options
