Stem Cell Science and Fat Transplantation
Cytori Therapeutics, Inc, a regenerative medicine company has developed an effective procedure of breast implantation in women by using the stem cell science in combination with the company’s procedure known as Celution 800. Latter is used in Europe and other parts of the world since year 2007 but the procedure is still waiting to be approved by the Food and Drug Administration (FDA) in the United States.
The company has successfully combined stem cell science and fat grafting which may significantly improve the outcome of breast implantations in women both for therapeutic and aesthetic purposes. The procedure which has also great potentials in cosmetic and reconstruction surgery is still being developed and bases on enlargement of fat cell density before being implanted. The fat stem cells may be used by the surgeon to stimulate the fat tissue that is a part of the operation and is believed to induce growth of blood vessels and enrichment of transplanted fat cells. In addition, the structure of the cells within the transplanted fat tissues becomes sturdier which reduces the risk of complications and improves the overall success rate of re-growth of the missing tissue.
Intermediate results of the procedure were presented at the 32nd Annual San Antonio Breast Cancer Symposium in December 2009 and have shown that over 70% of women and over 80% of physicians were satisfied with the results of the procedure involving stem cells 6 month later. The company also underlined that the procedure involving stem cells may not result in improvement of fat transplantation in patients with breast cancer that underwent radiation therapy after mastectomy (partial or complete breast removal) and lumpectomy (surgical removal of the tumor). Lesser success rate of the procedure in patients with breast cancer that underwent radiation therapy can be assigned to the breast tissue damage that was caused by the radiation therapy and difficulties in grafting.
