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…

New Cell That Keeps Stem Cells in the Bone Marrow
Chow et al. J Exp Med. When a bone marrow transplant is performed, the bone marrow cells of the donor are injected intravenously into the recipient and somehow find their way back into the bone marrow of the recipient. The mechanism known to be responsible for this has always been cited as being SDF-1 (also…

Arteriocyte gets FDA approval to begin critical limb ischemia clinical trial
Medcity News Critical limb ischemia is an advanced form of peripheral artery disease that causes hundreds of thousands of amputations per year. This condition is attractive to stem cell intervention because even a marginal improvement in circulation may be enough to prevent amputation. Previous work from Japan and Mike Murphy’s group at Indiana has demonstrated…

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…

Differences between Stem Cells from the Placenta and Bone Marrow
Fazekasova et al. Mesenchymal stem cells were historically isolated from the bone marrow as an adherent stem cell population capable of “orthodox” differentiation, meaning that they have ability to become bone, cartilage, and fat. Further research revealed that these cells are also capable of “non-orthodox” differentiation, that is, becoming neurons, hepatocytes, insulin producing cells, and…
