VIDEO: Shrinky-Dink Hanging Drops: A Simple Way to Form and Culture Embryoid Bodies
This video outlines the protocols for the most common method of creating embryoid body aggregates; using the hanging drop method.
On A ‘Roll’: Researchers Devise New Cell-sorting System
Capitalizing on a cell’s ability to roll along a surface, MIT researchers have developed a simple, inexpensive system to sort different kinds of cells – a process that could result in low-cost tools to test for diseases such as cancer, even in remote locations.
Researchers Control Growth Rate of Replacement Blood Vessels, Tissues
Researchers have discovered a way to control the growth rate of replacement tissue and the formation of new blood vessels, which solves one of the vexing problems of growing replacement tissue to treat injuries and trauma in humans.
Post Brain Injury: New Nerve Cells Originate from Neural Stem Cells
The study group of Prof. Dr. Magdalena Götz is able to show that after injury, reactive glial cells in the brains of mice restart their cell division. They then become stem cells from which nerve cells can form yet again under favourable cell culture conditions.
Injection of Human Umbilical Cord Blood Helps Aging Brain
When human umbilical cord blood cells were injected into aged laboratory animals, researchers at the University of South Florida found improvements in the microenvironment of the hippocampus region of the animals’ brains and a subsequent rejuvenation of neural stem/progenitor cells.
In Novel Strategy Against AIDS, Einstein Researchers Genetically Engineer Immune Cells Into Potent Weapons for Battling HIV Infection
By outfitting immune-system killer cells with a new pair of genes, scientists at the Albert Einstein College of Medicine of Yeshiva University transformed them into potent weapons that destroy cells infected with HIV, the virus that causes AIDS.
Long-term Muscle Improvements Shown In Gene Therapy Study In Mice
Injecting a gene responsible for making a specific protein into a mouse that’s used as a model for muscular dystrophy can lead to long-term improvements in the animal’s muscle size and strength, a new study shows.
Gene Therapy Could Save Kids From A Lifetime Of Eating Cornstarch
A gene therapy treatment that restores a missing liver enzyme in test animals could provide a cure for a rare metabolic disorder in humans, according to Duke University Medical Center researchers.
Gene Therapy Success Raises Hope of Huntington’s Treatment
Scientists are a step closer to curing a severe inherited brain-wasting disease using gene therapy. The illness is in the same family as Huntington’s disease, raising hopes that a similar approach could also be effective in that case.
Amazing Recovery Attributed to Cord Blood
A toddler diagnosed with cerebral palsy has shown remarkable improvement.
ABSTRACTS, REVIEWS AND SPECIAL REPORTS
Characterization of Adult Prostatic Progenitor/Stem Cells Exhibiting Self-Renewal and Multilineage Differentiation
These studies are the first to report a reproducible system to assess adult prostatic progenitor/stem cells.
Human Dental Pulp Stem Cells Improve Left Ventricular Function, Induce Angiogenesis, and Reduce Infarct Size in Rats with Acute Myocardial Infarction
This study suggests that dental pulp stem cells could provide a novel alternative cell population for cardiac repair, at least in the setting of acute myocardial infarction.
Banking on the Future of Stem Cells
Representatives of 21 stem cell funding agencies from 19 countries – members of the International Stem Cell Forum – met in San Francisco at the end of February to discuss collaborations and how to coordinate cell banks and registries. Among them was Leszek Borysiewicz, head of the UK Medical Research Council, who spoke to Nature about the effort.
