Recent news has indicated that adult stem cells, at least, are increasingly used in regenerative therapies. This press release reports on using stem cells taken from the patient's fat tissue to aid regrowth of large portions of the skull: "The result of the case study does not tell us to what extent the osteogenic effect is directly attributable to the combination of techniques using stem cells compared to the effect of the bone grafting alone. However, the outcome provides encouraging anecdotal evidence on the potential application for these cells to treat difficult bone defects, laying the groundwork for future work in this area. After twelve months, subsequent to the submission of our findings, the patient continues to do well and the skull is stable."
