Researchers at Hospital De San Jose in Colombia have utilized autologous (the patients’ own) stem cells to regenerate bone in children with cleft palates, greatly improving their quality of life by replacing an often arduous, surgically invasive procedure with a stem cell graft.The children partaking in the study were born with cleft palates, which typically require surgery and extensive grafting with bone from elsewhere in the body to create enough bone matter to support future teeth. When the children were born, their parents made the wise decision to bank their children’s powerful cord blood stem cells, which became vital to the success of this later treatment. This groundbreaking study used the patients’ own stem cells and a biological scaffold to allow the stem cells to grow into bone and fill the cleft. The ability to use autologous stem cells posed no risk of rejection to the patients, and in 5 and 10-year follow ups, the patients showed healthy bone development and experienced no adverse effects.
The National Heart, Lung and Blood Institute has recently invested $11.6 million into stem cell based regenerative research being conducted at the Temple University School of Medicine. Given the increased incidence of heart disease in recent years, stem cell based treatments are emerging as an optimal method of treatment, though there are still a few hurdles these treatments must overcome in order to be at their optimal effectiveness. Many of the challenges with current stem cell treatments for heart disease are due to the age of the patients and their age-related ailments. Obtaining stem cells for treatment at an older age reduces the stem cells’ efficacy - compared to younger cells, and also impacts the yield; often resulting in an insufficient number of cells for treatment.
