“We believe stem cells are always trying to repair tissue, but they don’t do it well — not because we lack stem cells but, rather, the signals that regulate our stem cells are impaired,” said lead author Marc Penn, M.D., Ph.D., research director at Summa Cardiovascular Institute in Akron, Ohio.
The materials, including the biomedical implantable material polycarbonate plastic, which is a versatile plastic used in things from bulletproof windows to CDs, offer an accessible and cheaper way of culturing hESCs and present new opportunities for future medical research in this area.
In the study “REDDSTAR” (Repair of Diabetic Damage by Stromal Cell Administration), led by researchers from Queen’s Centre for Vision and Vascular Science (QCVVS), stem cells are being isolated from donors, expanded in a laboratory setting and re-delivered to patients in an attempt to repair the
At the same time the team is testing an innovative new treatment regimen designed to prevent rejection of the limbs. During the transplant procedure Marrocco was given an infusion of the donor’s bone marrow cells.
The study looked at the $1.5 billion in grant awards committed by July 2012, and the one-time economic impact they will have through 2014. These awards represent half of the $3 billion CIRM was allotted through the passage of Proposition 71 in 2004.
"We're finding that the effect of stem cell therapy is indirect. It stimulates proliferation of dormant surviving host heart tissue, and it attracts stem cells already in the heart.
