Skin-cell spray gun drastically cuts healing time for burns
In the past, the most common way to treat first to second degree burns is with skin grafts, a process that includes taking pieces of skin from uninjured parts of the patient’s body or grafting artificial skin and grafting them over the burned area. This treatment was somewhat effective, however resulted in a recovery period…

UW Researchers Make Stem Cell Breakthrough
Seung Park, Badger Herald Researchers at the University of Wisconsin have made a breakthrough in stem cell research. Igor Slukvin headed the team that has successfully reprogrammed bone marrow cells into induced pluripotent stem cells (iPSCs). “This is important because blood banks have huge amounts of samples of bone marrow,” he said. “You can select…

New Stem Cells Found in Ovary
Parte et al. Stem Cells Dev. Very small embryonic like cells (VSEL) are a type of stem cell that appears to be found in bone marrow and other tissues of the body, presumably as a remnant of embryonic or embryonic-like cells left over from development. In a recent paper it was demonstrated that these cells…

Injured Liver Calls in Bone Marrow For Help?
Li et al. Cells Tissues Organs It is known that administration of bone marrow cells into patients with liver failure has the ability to improve enzyme function and overall health http://www.youtube.com/watch?v=DdH6Mm4w98I. Additionally, numerous animal models have demonstrated that injection of various types of stem cells can result in regeneration of injured liver tissue. For example,…

Scientists look to stem cells to mend broken hearts
Cardiac medicine has traditionally been associated with innovative procedures that sometimes where considered heretical to the present day dogma. For example, the first heart transplant, the use of the balloon catheter, the introduction of thrombolytics, all met substantial resistance from the “establishment” in their time. It appears that the next revolution in cardiac medicine is…

Limb Transplants Facilitated by Bone Marrow Stem Cells
Kuo et al. Plast Reconstr Surg. 2011 Feb;127(2):569-79. Composite tissue allografts are usually transplants of anatomical structures that contain multiple types of tissues. We have seen numerous high-profile examples of human composite tissue allografts such as whole hands, faces, and arms. While advancement of surgical techniques have made such transplants a reality, immunologically-mediated rejection remains…

Nine Patients with Crohn’s Disease Treated by Intravenous Administration of Mesenchymal Stem Cells
Marjolijn et al. Gut 59:1662 Mesenchymal stem cells are known to be suppressive to immune cells such as T cells, dendritic cells, and natural killer cells. Studies have demonstrated that patients suffering from the immune disease graft versus host enter remission after administration of donor or third party mesenchymal stem cells. One of the manifestations…

Male-Pattern Baldness Found Rooted in Stem Cells
Amanda Chan, MyHealthNewsDaily Staff Writer A new discovery regarding the presence of stem cells in males with androgenetic alopecia (male-pattern baldness) has led to hope that the disease may be treatable. It was previously believed that people who suffered from baldness also had a depleted number of hair follicle stem cells, meaning that new hair…

Study Shows Patient’s Own Stem Cells Help Stroke Recovery: 16 Treated Patients Improve in Comparison to 36 Controls
Lee et al Stem Cells 28:1099 Stroke is caused by blocked circulation to parts of the brain usually as a result of a blood clot. Outcomes of stroke are generally proportional to the length of time the circulation was blocked and to the amount of brain tissue injury and death. Although the introduction of “clot…
