To treat a complicated,
non-healing bone defect, surgeons often use an implant with living cells to promote bone repair, but the implanted cells have a small chance of surviving because they are not prepared for a lack of oxygen and nutrients at the fracture site.

with bone defects, the osteoblasts formed new bone tissues in vivo without any signs of teratoma formation.
Ata has a range
of bone defects that led to wild speculation that we had discovered an extraterrestrial.
However, the need for the rapid point - of - care clinical application of BM stem cells for
bone defect repair will not allow for the purification of hMSCs from the BM, and so, the authors assessed the effect of transient BIO exposure to whole BM samples.
A team of New York Stem Cell Foundation (NYSCF) Research Institute scientists report today the generation of patient - specific bone substitutes from skin cells for repair of large
bone defects.
While severity varies,
bone defects and injuries are currently treated with bone grafts, taken either from another part of the patient's body or a donor bone bank, or with synthetic substitutes.
In future research, we will examine whether this technique also works in even larger
bone defects and by using human cells.»
These encouraging data suggest that transient BIO treatment may represent a safe and rapid strategy to enhance the osteogenic potential of patient BM stem cells,
a bone defect repair approach that the authors believe is a faster path to clinical translation than the treatment of purified and ex vivo - amplified hMSCs.
