Lab-grown sperm cells used to create healthy baby mice

Researchers from the Chinese Academy of Sciences have successfully created functional sperm cells from mouse stem cells in the laboratory, then implanted those cells into rodents' egg cells to produce healthy, fertile offspring. While a lot more work needs to be done before human trails could be considered, the breakthrough could be significant, with the potential to combat male infertility.Read More

Ordinary skin cells turned into brain tumor predators

The 2006 discovery that mature skin cells can be converted into stem cells opened up exciting possibilities in regenerative medicine. Now almost a decade later, the Nobel-Prize winning research of Shinya Yamanaka is still opening doors for scientists across different arms of medical research. In what it labels as a first, a team from the University of North Carolina at Chapel Hill (UNC) has built on this technology to transform adult skin cells into cancer-killing stem cells that seek and destroy brain tumors.Read More

Insulin-producing mini stomachs promise patient-specific diabetes treatment

Patients with Type 1 diabetes suffer from an absence of pancreatic cells called beta cells, which are responsible for producing insulin. Researchers have been trying to tackle the deficiency for decades, but now it seems that significant progress may have been made – a team of scientists lead by researchers from the Harvard Stem Cell Institute have discovered that it might be possible to engineer tissue from the lower stomach to address patients' insulin needs.Read More

Electrically-trained muscle cells get damaged hearts pumping

Repairing damaged hearts with healthy cells derived from the patient's own skin or blood is a promising approach to tackling cardiovascular disease, but it does have its limitations. Difficulty in getting the young, freshly implanted cells to integrate and beat in-synch with the surrounding muscle has so far held the technique back. Now scientists are reporting an important advance in this area, demonstrating for the first time that electrically stimulating the new cells can give their development a critical boost. Read More

Hydrogel boosts uptake of stem cells in repairing damaged hearts

With their ability to help repair damaged muscle, stem cells have shown promise as tools for rebuilding the body's organs, but their potential is yet to be fully realized – especially when it comes to the heart. Part of this is because only a small percentage of stem cells injected actually survive the process, but a newly developed liquid could make life a little easier for freshly transplanted cells. Researchers have found that encapsulating them in a sticky hydrogel gives them the ability to not only survive, but multiply and improve the injured heart's ability to pump blood. Read More

Existing skin medications may reverse effects of multiple sclerosis

It's a frustrating situation. There are already stem cells in the nervous system that are capable of repairing the damage done by multiple sclerosis, but getting them to do so has proven very difficult. Now, however, a multi-institutional team led by Case Western Reserve University's Prof. Paul Tesar may have found the answer – and it involves using medications that were designed to treat athlete's foot and eczema.
