Researchers seeking a cure for Type 1 diabetes may be a giant step closer to the prize. For most people with this chronic condition, the immune system goes awry, destroying insulin-producing (islet) cells in the pancreas. When a substantial number of these cells are wiped out, little or no insulin is produced. With no insulin to...

In the fall of 2010, a team of scientists in California injected human stem cells into the spinal cords of mice with a crippling condition similar to multiple sclerosis, figuring that the mice would reject the cells as they might reject an organ transplant. According to Tom Lane, a University of California, Irvine pathologist who...

Scientists have reached a new level in the use of stem cells to grow organs. Human heart tissue that was grown in a petri dish contracted spontaneously, encouraging news for the millions of people who die from cardiovascular ailments annually. Complications associated with organ transplants have limited the number of those with cardiovascular disease from...

For the first time, researchers have been successful at reprogramming an animal’s adult cells so that they can grow into various types of tissue. In Madrid, Spain, researchers at the Spanish National Cancer Research Centre were successful at accomplishing in mice what had previously only been performed in a petri dish. This research leads to...

Left mostly to their own devices, a group of intrepid human stem cells at Vienna’s Austrian Academy of Science knitted themselves into tissue with a variety of brain structures and specialized groups of neurons. In essence, they created a BB-sized neural ball reminiscent of a nine-week-old fetus brain. And while the clumps of tissue are still...

Creating a batch of stem cells may have just gotten a whole lot easier. A new recipe for creating pluripotent stem cells calls for adding just seven molecules to an existing adult stem cell. The method has been used on mature mouse cells, which were converted into the embryonic-type cells. These pluripotent cells can then be...

Scientists and cell biology experts at the University of Michigan’s Medical School have taken a stem-cell-based approach to studying the origins and possible treatment routes for epilepsy. Converting skin cells from current epilepsy patients into stem cells, the scientists could turn those stem cells into neurons. Utilizing these brain nerve cells, the team was then...

Researchers at Johns Hopkins made big steps towards the eventual creation of customized blood vessels this month. Creating new blood vessel networks from stem cells, the scientists were able to successfully transplant them into laboratory mice. The manufactured blood vessel network, which is produced through the reprogramming of ordinary cells, is a big accomplishment in...

A new stem cell biology-based approach may one day help the thousands of patients in need of a liver transplant every year. In 2011, around 5,800 liver transplant surgeries were performed in the United States. That same year, nearly 3,000 more patients died while waiting for their turn on the waiting lists. This scarcity of human...

A team of dedicated scientists at the University of Oregon has made some fascinating discoveries towards understanding how stem cells produce not only new, but varied neurons. Studying the brains of fruit flies, biologists set out to answer the question of how a single type of stem cell can create a variety of different kinds of...
