Researchers from University of Connecticut have discovered a population of stem cells having the ability to generate new bone. These stem cells reside along the vascular channels which stretch across the bone. These vascular channels connect the inner and outer parts of the bone.
Lead investigator Dr. Ivo Kalajzic, said, “”This is a new discovery of perivascular cells residing within the bone itself that can generate new bone forming cells,”
“These cells likely regulate bone formation or participate in bone mass maintenance and repair.”
Earlier scientists consider that Stem cells are present within bone marrow and the outer surface of bone. However, recently scientists have discovered the existence of a network of vascular channels. These vascular channels facilitate distribution of blood cells out of the bone marrow. But none of the research has proved the existence of cells within these channels that have the ability to form new bones.
Now in this revolutionary study, Kalajzic and his team informed about the existence of these progenitor cells within cortical bone. These progenitor cells can produce new bone-forming cells called osteoblasts, which can be used to help remodel a bone.
