Move over Gucci; researchers create designer stem cells

UW Medicine researchers recently lead a successful effort to create “designer” stem cells that might lead to advances in cancer and aging, they say. In a paper published this week in the journal PNAS, the scientists showed for the first time that a computer-generated protein can be inserted into stem cells to change their epigenetic memory, whose role is to […]

Bone Marrow Protein May Be Target for Improving Stem Cell Transplants

Bone marrow contains hematopoetic stem cells, the precursors to every blood cell type. These cells spring into action following bone marrow transplants, bone marrow injury and during systemic infection, creating new blood cells, including immune cells, in a process known as hematopoiesis. A new study led by University of Pennsylvania […]

Why placebo effect works only for some people? Scientists think they may have the answer

Everyone knows that placebo is capable of effectively reducing pain, but people respond differently to placebo treatment. A new study from the University of Luxembourg revealed that it depends heavily on person‘s ability to reinterpret negative events and to control feelings. Interestingly, this was figured out using fMRI technology. Placebo […]

Digital storytelling helps people with dementia trigger memories

For Myrna Caroline Jacques, digital storytelling is her way of fighting Alzheimer’s. “I thought maybe if I do this and use my brain, the disease won’t take over as soon. “That’s my goal,” the 77-year-old grandma of five said. She may be onto something. A recent UAlberta study on digital […]

Stem Cell Treatment for Children With Spina Bifida Helps Dogs First

A pair of English bulldog puppies are the first patients to be successfully treated with a unique therapy — a combination of surgery and stem cells — developed at the University of California, Davis, to help preserve lower-limb function in children with spina bifida. Because dogs with the birth defect […]

Artificial Intelligence Algorithm Predicts Dementia two Years before the Onset of Symptoms

Drawing on available data on people with mild cognitive impairment (MCI) from the Alzheimer’s Disease Neuroimaging Initiative (ADNI), researchers at McGill University in Canada had trained a machine-learning algorithm to identify which patients will go on to develop dementia within a 24 month period with 84% accuracy. The data used […]

Two-step process leads to cell immortalization and cancer

A mutation that helps make cells immortal is critical to the development of a tumor, but new research at UC Berkeley suggests that becoming immortal is a more complicated process than originally thought. The key to immortalization is an enzyme called telomerase, which keeps chromosomes healthy in cells that divide […]

Are stem cells the link between bacteria and cancer?

Gastric carcinoma is one of the most common causes of cancer-related deaths, primarily because most patients present at an advanced stage of the disease. The main cause of this cancer is the bacterium Helicobacter pylori, which chronically infects around half of all humans. However, unlike tumour viruses, bacteria do not deposit […]

Nerve-guiding ‘labels’ may one day help re-form broken nervous connections

Scientists have identified a large group of biological ‘labels’ that guide nerves to ensure they make the correct connections and control different parts of the body. Although their research was conducted with fruit flies, the findings offer hope that we could one day reestablish nervous connections in people living with […]

Adult brains produce new cells in previously undiscovered area

A University of Queensland discovery may lead to new treatments for anxiety, depression and post-traumatic stress disorder (PTSD). UQ Queensland Brain Institute scientists have discovered that new brain cells are produced in the adult amygdala, a region of the brain important for processing emotional memories. Disrupted connections in the amygdala, […]

Stress may be one of the key contributing factors in Alzheimer’s disease

Our modern lives are extremely stressful. We have to rush pretty much everywhere and are always haunted by a huge fear of getting late and being replaced. However, you may want to consider this – a new study showed that stress may be a major contributor to the development of […]

Scientists identify a new way to activate stem cells to make hair grow

UCLA researchers have discovered a new way to activate the stem cells in the hair follicle to make hair grow. The research, led by scientists Heather Christofk and William Lowry, may lead to new drugs that could promote hair growth for people with baldness or alopecia, which is hair loss […]

Link between biological clock and aging revealed

Scientists studying how aging affects the biological clock’s control of metabolism have discovered that a low-calorie diet helps keep these energy-regulating processes humming and the body younger. In a study appearing today in the journal Cell, Paolo Sassone-Corsi, director of the Center for Epigenetics & Metabolism at the University of […]

Novel Stem Cell-Derived Model Created of Inflammatory Neurological Disorder

An international team of scientists, led by University of California San Diego School of Medicine researchers, has created a human stem cell-based model of a rare, but devastating, inherited neurological autoimmune condition called Aicardi-Goutieres Syndrome (AGS). In doing so, the team was able to identify unusual and surprising underlying genetic […]
