Scientists seeking new ways to fight maladies ranging from arthritis and osteoporosis to broken bones that won’t heal have cleared a formidable hurdle, pinpointing and controlling a key molecular player to keep stem cells in a sort of extended infancy. It’s a step that makes treatment with the cells in the future more likely for patients.
Controlling and delaying development of the cells, known as mesenchymal (pronounced meh-ZINK-a-mill) stem cells, is a long-sought goal for researchers. It’s a necessary step for doctors who would like to expand the number of true

AUGUSTA, Ga. – Medical College of Georgia researchers are conducting the first FDA-approved clinical trial to determine whether an infusion of stem cells from umbilical cord blood can improve the quality of life for children with cerebral palsy.
The study will include 40 children age 2-12 whose parents have stored cord blood at the Cord Blood Registry in Tucson, Ariz.
Umbilical cord blood is rich in stem cells, which can divide and morph into different types of cells throughout the body, said Dr. James Carroll, professor and chief of pediatric neurology in MCG School of Medicine and principal investigator
A particular type of stem cell transplantation using the patient’s own cells led to short-term freedom from insulin injections in 20 of 23 patients newly diagnosed with type 1 diabetes participating in an experimental protocol in Brazil.
One patient even managed to go four years without needing outside sources of insulin, although the average was 31 months, said the authors of a report in the April 15 issue of the Journal of the American Medical Association, a themed issue on diabetes.
The patients also kept their blood sugar under control, which is key to preventing complications from diabetes. And, the authors
Research led by Charles Cox at the University of Texas Health Science Center has shown that stem cell therapy given during the critical time window after traumatic brain injury promotes lasting cognitive improvement.
These experiments, which were published in the latest issue of the journal Stem Cells Translational Medicine, provide a pre-clinical model for experiments with larger animals.
After the brain has suffered a traumatic injury, there are few treatment options. Damage to the brain can be severe, and can also cause ongoing neurological impairment. Approximately half of all patients with severe head injuries need surgery to remove or repair ruptured
Bone marrow stem cells self transplant can reduce Multiple Sclerosis (MS) symptoms, and make the disease regress in some cases.
These are the hopeful results from a research on 21 patients diseased by MS, made by the Chicago Northwestern University School of Medicine and published on Lancet Neurology. “Since 3 years from self transplant all the patients watch their conditions better.”
Since these results, doctors decided to make a bigger research involving more MS diseased people and comparing new therapy’s results with olds’ ones.
The experiment is about taking marrow stem cells and then treating them to remove ill lymphocytes which attack
