Still, I m worried that before such welcome changes are made, considerable funds and resources may be wasted on data systems required to meet rules that later change. The rules may dramatically increase health care costs and liability. The rules provisions on parental access erode the privacy of children. Considerable funds may be wasted on systems meeting rules that later change. A large number of stem cells were isolated from liposuctioned fat.
Fetal tissue provides the largest number of stem cells with the least risk of rejection.
As controversy continues to swirl around the use of embryonic stem cells to treat disease, it appears that adult stem cells typically found in very small numbers in the brain and bone marrow may be at least as effective as their fetal counterparts. And there was more good news about adult stem cells this week. Once isolated, the stem cells were converted into bone, cartilage, and muscle cells after being exposed to a mixture of chemicals and growth factors. The authors of the Tissue Engineering paper, Mark Hedrick, MD, of the University of California, Los Angeles, and Adam J. Katz, MD, of the University of Pittsburgh, suggest that one of the first applications of this technology could be cartilage implants to repair joints such as the knee, since the supply of laboratory-grown cartilage cells currently used for this is limited. Autologous fat cells transformed into cartilage have the additional potential advantage of little or no transplant rejection.
