Brain cells found to control aging
Scientists have found that stem cells in the brain's hypothalamus govern how fast aging occurs in the body. The finding, made in mice, could lead to new strategies for warding off age-related diseases and extending lifespan.

Scientists are on the verge of being able to create 'limitless supplies' of blood
Scientists believe they are “tantalisingly close” to being able to make a “limitless supply” of blood to treat people with blood disorders and immune condition and help give transfusions. For nearly 20 years, researchers have been trying to find a way to turn stem cells – which can create any kind of cell – into blood artificially.

Breast Implants Using Stem Cells Are Officially A Thing In The US
They've been in Japan for a while and the UK has dabbled. Now breast implant proIn 2001, President George W. Bush’s administration restricted federal funding for research on stem cells obtained by human embryos. The medical practice was relatively unknown at the time, and it was characterized as “playing God” with the most customizable cells in the body. When the ban was lifted in 2009, it was like opening Pandora’s Box, with exciting new research initiatives and treatments for injuries, vision problems, and of course cancer. Even NFL stars like Peyton Manning jumped...

Paralyzed man regains use of arms and hands after experimental stem cell therapy
Doctors at the USC Neurorestoration Center and Keck Medicine of USC injected an experimental treatment* made from stem cells and other cells into the damaged cervical spine of a recently paralyzed 21-year-old man as part of a multi-center clinical trial. Two weeks after surgery, Kristopher (Kris) Boesen began to show signs of improvement. Three months later, he’s able to feed himself, use his cell phone, write his name, operate a motorized wheelchair, and hug his friends and family. Improved sensation and movement in both arms and hands also make it easier for Kris to care for himself, and to envision a life lived more independently.

Researchers use light to coax stem cells to repair teeth
Cambridge/Boston, Mass. – May 28, 2014 – A Harvard-led team is the first to demonstrate the ability to use low-power light to trigger stem cells inside the body to regenerate tissue, an advance they reported in Science Translational Medicine. The research, led by David J. Mooney, Robert P. Pinkas Family Professor of Bioengineering at the Harvard School of Engineering and Applied Sciences (SEAS), lays the foundation for a host of clinical applications in restorative dentistry and regenerative medicine more broadly, such as wound healing, bone regeneration, and more.

New MS treatment using stem cells may produce revolutionary results
A novel Canadian treatment to halt the progression of multiple sclerosis (MS) is being hailed as revolutionary, after doctors and researchers used the new stem cell transplant method to treat the disease. The results of the trial, published in The Lancet medical journal, showed long-term improvement of disease control in 23 out of 24 MS patients tested. The treatment combined chemotherapy and a stem cell transplant. It halted relapses and the development of new brain lesions in 23 of 24 patients...

Stanford researchers ‘stunned’ by stem cell experiment that helped stroke patient walk
Stanford researchers studying the effect of stem cells injected directly into the brains of stroke patients said Thursday that they were "stunned" by the extent to which the experimental treatment restored motor function in some of the patients. While the research involved only 18 patients and was designed primarily to look at the safety of such a procedure and not its effectiveness, it is creating significant buzz in the neuroscience community because the results appear to contradict a core belief about brain damage — that it is permanent and irreversible.

3D printing of implants during a surgery soon possible
Surgeons can soon use a 3D printing pen to build customized cartilage tissues during surgery. The pen with bio-ink which supports human stem cells can print cells according to the precise geometry of the implant needed. Australian researchers were able to 'draw' human stem cells in freeform patterns with extremely high survival rates. Developed by a team from ARC Centre of Excellence for Electromaterials Science...

'Sci fi' eye experiments improve vision in children — and rabbits
Discs made of multiple types of eye tissue have been grown from human stem cells — and that tissue has been used to restore sight in rabbits. The work, reported today in Nature1, suggests that induced pluripotent stem (iPS) cells — stem cells generated from adult cells — could one day be harnessed to provide replacement corneal or lens tissue for human eyes. The discs also could be used to study how eye tissue and congenital eye diseases develop.

First new sound wave class in half a century to revolutionize stem cell therapy
A new class of sound wave has been developed for the first time in 50 years that looks set to revolutionize the use of stem cells in medical treatments. Created by acoustics experts from RMIT University in Melbourne, Australia, the sound waves – known as “surface reflected bulk waves” – are gentle enough to manipulate stem cells without causing damage, something that has not previously been possible with sound waves.

Surgeons test possible stem cell cure for blindness
Surgeons test possible stem cell cure for blindness. Surgeons in London have used human embryonic stem cells in a pioneering attempt to cure blindness. Cells derived from a donated early embryo were implanted into the retina of a 60-year-old woman with age-related macular degeneration - the most common cause of blindness in the UK.
