Howard Hughes Medical Institute (HHMI) scientists have discovered that endothelial cells, the building blocks of the vascular system, keep blood stem cells dividing healthily in a lab dish much longer and more effectively than previous methods of growing the cells. The new advance dramatically improves scientists’ ability to manufacture large quantities of authentic adult blood stem cells, which may help revolutionize the field of bone marrow transplantation.

A leading specialty hospital has demonstrated that bone marrow stem cells can cure blood disorders like leukemia, thalassemia and aplastic anemia, a bone marrow failure.
“Bone marrow transplant has emerged as an effective cure for cancerous and genetic blood diseases through transfusion of its stem cells from a healthy donor to an affected patient,” Narayana Health City consultant hematologist Sharat Damodar told reporters here Tuesday.
The corporate hospital in the city’s southern suburb claims to have performed about 300 bone marrow transplants with over 80 per cent success rate.

Scientists have pioneered a unique delivery system to administer therapeutic stem cells to the brain, by way of a simple nasal spray. Once the droplets containing the stem cells are snorted through the nose, the solution breaks through the blood-brain barrier, seeding the brain with the stem cells (…)
Scientists from the University of Minnesota and the University Hospital of Tuebingen, Germany conducted the research. The researchers administered the nasal spray containing rat stem cells to mice and within an hour, the rat stem cells were visible in the mice brains. The researchers then repeated the experiment

A study published this week reinforces the potential value of stem cells in repairing major injuries involving the loss of bone structure.
The study shows that delivering stem cells on a polymer scaffold to treat large areas of missing bone leads to improved bone formation and better mechanical properties compared to treatment with the scaffold alone. This type of therapeutic treatment could be a potential alternative to bone grafting operations.
“Massive bone injuries are among the most challenging problems that orthopedic surgeons face, and they are commonly seen as a result of accidents as well as in soldiers returning
Stem Cell Research Treats First Patient With Stem Cells From His Own Heart
The song “Take another little piece of my heart” by Janis Joplin has new meaning today as doctors in Los Angeles have taken Adult Stem Cells directly from a heart attack patient’s heart and used those stem cells to treat the patient in […]
