1. Scientists find approach to enhance and prolong immune attack against tumor cells Investigators have identified a new class of human immune cells that behave like stem cells. These cells, a subtype of T lymphocytes, which comprise a small fraction of white blood cells, may prove more effective than any previously reported type of T cell for treating tumors. The study, by scientists at the National Cancer Institute […]...

MedicareCard.com – NIH Study Confirms Location of Stem Cells Near Cartilage-Rich Regions in Bones Working with mice, a team of researchers has pinpointed the location of bone generating stem cells in the spine, at the ends of shins, and in other bones. The team also has identified factors that control the stem cells’ growth. The research was conducted at the National Institutes of Health and other institutions....
3. Uterine stem cells used to treat diabetes in mice Researchers funded by the National Institutes of Health have converted stem cells from the human endometrium into insulin-producing cells and transplanted them into mice to control the animals’ diabetes....
4. Researchers design a light therapy that targets and destroys cancer cells in mice Researchers have designed a light-based therapy that allows the selective destruction of tumor cells in mice without harming surrounding normal tissue. This method of cancer therapy could theoretically work against tumors in humans, such as those of the breast, lung, prostate, as well as cancer cells in the blood such as leukemias, say scientists from […]...

6. NIH researchers discover new method to label cells for tracking by MRI Researchers have developed a method to label transplanted cells so they can be tracked by magnetic resonance imaging (MRI). In the future, as cell therapies become a more integral part of regenerative medicine and tumor treatment, there could be increased need to measure how many transplanted immune or stem cells reach their target....

Medicare Card, Scientists Identify Markers, Human Breast Cancer Cells, Linked to Development of an Aggressive, But Less Common Form of Breast Cancer Scientists have identified a group of surface markers on cells linked to an aggressive type of breast cancer called estrogen receptor-negative cancer. In this preliminary study, estrogen-negative breast cancer developed when three markers, CD44+, CD49fhi, and CD133hi were present simultaneously on the surface of human cells taken from breast cancer patients and transplanted into a […]...

Rao, M.D., Ph.D. as the director for the new NIH Intramural Center for Regenerative Medicine (NIH-CRM). The NIH-CRM is an initiative to create a world-class center of excellence in stem cell technology on the NIH campus, including induced […]...
9. New model of ALS is based on human cells from autopsied tissue By isolating cells from patients’ spinal tissue within a few days after death, researchers funded by the National Institutes of Health have developed a new model of the paralyzing disease amyotrophic lateral sclerosis (ALS). They found that during the disease, cells called astrocytes become toxic to nerve cells — a result previously found in animal […]...
10. Delayed stem cell therapy following heart attack is safe but not effective Stem cells obtained from bone marrow, known as BMCs, can be safely injected into people 2-3 weeks following a heart attack, reports a new clinical trial supported by the National, Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health. However, while safe, the BMCs did not improve heart function six months […]...

12. Cells’ energy factories linked to damaging inflammation Scientists have discovered that molecules called reactive oxygen species (ROS) produced by the energy factories, or mitochondria, in cells, may play a role in a rare inherited disorder in which uncontrolled inflammation damages the body’s tissues. Their research in human and mouse cells suggests that blocking these molecules could reduce inflammation in TNF receptor-associated periodic […]...
