“This must be taken into consideration when grafting stem cells,” Dr. Papaccio continued. “Their behavior may be quite variable and, consequently, their differentiation fate in some cases may be affected more by their specific origin than by the local signals of the treated area.
“Although the bone regenerated at the graft sites is not of the proper type found in the mandible,” he added, “it does seem to have a positive clinical impact. In fact, it creates steadier mandibles, may well increase implant stability and, additionally, may improve resistance to mechanical, physical, chemical and pharmacological agents.”
“Dental pulp is an interesting source of ready-to-use stem cells to treat bone defects,” said Anthony Atala, M.D., Editor of STEM CELLS Translational Medicine and Director of the Wake Forest Institute for Regenerative Medicine. “The finding that these cells regenerate compact bone in the mandible indicates a potential role in the treatment of oral cancer.”
