A soft spot for stem cells helps cornea healing

New research led by scientists at Newcastle University, UK reveals a potential revolutionary way to treat eye injuries and prevent blindness—by softening the tissue hosting the stem cells which then helps repair wounds, inside the body. The team discovered that the simple application of a tissue-softening enzyme, collagenase, prevents the loss of corneal stem cells

Coeliac disease can cause irreversible changes to immune cells

Immune cells in the bowel of people who suffer with coeliac disease are permanently replaced by a new subset of cells that promote inflammation, suggests a new study involving researchers at Cardiff University. This permanent ‘immunological scarring’ lays the foundation for the disease to progress and could have long-term implications for gut health in affected

Electrical activity in prostate cancer cells

Experts from the Universities of Bath and Seville have carried out a series of experiments by which, for the first time, they have characterized the normal electrical activity in PC-3 prostate cancer cells in real time, with a resulting low-frequency electrical pattern between 0.1 and 10 Hertz. “We have observed that this electrical activity evolves

Implanting stem cells into the brain could stop epileptic seizures

Hope for epileptics as scientists discover implanting stem cells into the brain could stop seizures The treatment, tested on rats, would modify the patient’s own skin cells Stem cell treatment led to 70% fewer seizures in the months following It inhibits excitement in the hippocampus, where epileptic seizures can start  Currently, surgery to remove the hippocampus

Researchers discover abundant source for neuronal cells

USC researchers seeking a way to study genetic activity associated with psychiatric disorders have discovered an abundant source of human cells—the nose. Olfactory epithelial cells, easily collected from the lining of the nasal cavity, can serve as stand-ins for brain cells in studies of the neuronal epigenome, USC researchers say. The epigenome is a system

A fully human system to cultivate skin cells for grafting

Breakthrough study to culture human skin cells called keratinocytes to produce skin grafts has been published by a team of researchers from Duke-NUS Medical School and the Singapore General Hospital (SGH). This method is the first to use a specific type of tissue-proteins known as laminins, found in the human body, to create a safer

Mouse and human skin cells produce melanin on a 48-hour cycle

Researchers have discovered that mouse skin and skin cells from humans produce pigmentation in response to sunlight on a 48-hour cycle. They observed that exposing skin to ultraviolet light every 2 days yielded darker pigmentation with less radiation damage than daily exposure. The findings appear October 25 in the journal Molecular Cell. “The damaging effects

New way to determine whether metastatic cancer cells in breast cancer patients are dormant or soon to turn deadly

For the first time ever, Mount Sinai researchers have identified a protein as a marker that can indicate whether a cancer patient will develop a reoccurrence of lethal, metastatic cancer, according to a clinical study published in Breast Cancer Research in October. The researchers found that when cells from a breast cancer patient’s original tumor

Olfactory cells may act as ‘Trojan horse,’ carry anticancer therapy to deadly brain tumors

A special type of cell essential to the ability of olfactory neurons to regenerate may be genetically engineered to deliver anticancer therapy to the dangerous brain tumors called glioblastomas. In their report published in the Journal of the National Cancer Institute, Massachusetts General Hospital (MGH) researchers describe using olfactory ensheathing cells to deliver an anticancer

Duchenne muscular dystrophy: How muscle cells journey to the dark side

Promoting repair of dystrophic muscles is a major goal in the treatment of muscular dystrophies but is complicated by the incomplete knowledge of the cellular and molecular events that drive muscle regeneration. Answers could lie in better understanding muscle repair—which resembles a delicate cellular dance choreographed by special cells called fibro-adipogenic progenitors (FAPs). Researchers already

New mechanism activates bone-building cells in osteoperosis

The number of osteoporosis medications that promote bone formation are few compared to those that suppress bone resorption. A research group led by Kumamoto University scientists has discovered that the gene SIRT7 is important for bone formation, and has discovered a new mechanism to activate gene functions essential for bone formation. The researchers believe that
