A new study appearing in STEM CELLS Translational Medicine (SCTM) demonstrates the potential of a subset of stem cell called CD34+ in treating hard to heal bone fractures.
While most patients recover from broken bones with little or no complication, up to 10 percent experience fractures that won’t heal. This can lead to a number of debilitating side effects, from infection to bone loss, and it can require extensive treatment involving multiple operations and prolonged hospitalization as well as long-term disability.
Regenerating broken bone using stem cells could offer an answer. Adult human peripheral blood CD34+ cells have been shown to contain an abundance of a type of stem cell called endothelial progenitor cells (EPCs) as well as hematopoietic stem cells, which give rise to all types of blood cells. As such, they could be good candidates for this therapy.
