Scientists identify unique molecular signature in iPSCs that show promise in regenerative medicine

Salk scientists have identified a unique molecular signature in induced pluripotent stem cells (iPSCs), "reprogrammed" cells that show great promise in regenerative medicine thanks to their ability to generate a range of body tissues.

Scientists describe how natural selection occurs at the cellular level

Scientists from the Spanish National Cancer Research Centre (CNIO) describe how natural selection also occurs at the cellular level, and how our body's tissues and organs strive to retain the best cells in their ranks in order to fend off disease processes.

Sanford-Burnham professor to develop personalized models of inherited heart conditions

The California Institute for Regenerative Medicine (CIRM) has awarded a $1.58 million grant to Huei-Sheng Vincent Chen, Ph.D., associate professor at Sanford-Burnham Medical Research Institute (Sanford-Burnham). Chen's proposal was one of 28 new projects funded as part of CIRM's Basic Biology IV awards program, which supports basic research aimed at increasing our understanding of stem cells and how to work with them.

Therapeutic targets for pemphigus vulgaris discovered

Researchers have identified the primary target of the autoantibodies found in the serum of patients with the blistering skin disorder pemphigus vulgaris.

Researchers turn skin cells into embryonic Sertoli-like cells

Using a stepwise trans-differentiation process, Whitehead Institute researchers have turned skin cells into embryonic Sertoli-like cells.

Converting blood cells to a stem cell state: an interview with Elias Zambidis, M.D., Ph.D.

The primitive stem cell state we created is called an “induced pluripotent stem cell” (iPSC). iPSC are a new, unique, and artificially-created type of stem cell that were first described in 2006 by a Japanese scientist named Shinya Yamanaka.

ABCD4 and CblF proteins responsible for hereditary vitamin B12 deficiency

Vitamin B12 is vital for cell division, the synthesis of red blood cells and the functioning of the nervous system. Unable to produce the vitamin itself, the human body has to obtain it via animal proteins. So far it has been known that on its way into the cell vitamin B12 is absorbed by little organelles, so-called lysosomes. From there, the vitamin enters the cell interior with the aid of the transport protein CblF, which was discovered by the same research team three years ago.

Scientists develop reliable method to convert adult blood cells into iPSCs

Johns Hopkins scientists have developed a reliable method to turn the clock back on blood cells, restoring them to a primitive stem cell state from which they can then develop into any other type of cell in the body.

ACS National Meeting & Exposition focuses on DNA wires and their potential use in identifying diseases

In a discovery that defies the popular meaning of the word "wire," scientists have found that Mother Nature uses DNA as a wire to detect the constantly occurring genetic damage and mistakes that ― if left unrepaired ― can result in diseases like cancer and underpin the physical and mental decline of aging.

Inhibiting over-production of Panx1 protein can treat melanoma

New research from Western University, Canada, has identified a potential new target for the treatment of melanoma, the deadliest of all skin cancers. Silvia Penuela and Dale Laird discovered a new channel-forming protein called Pannexin (Panx1) that is expressed in normal levels on the surface of healthy skin cells.

Pathway describes how alpha hydroxyl acids cause skin exfoliation

A team of investigators from UC Davis and Peking University have discovered a mechanism that may explain how alpha hydroxyl acids (AHAs) -- the key ingredient in cosmetic chemical peels and wrinkle-reducing creams -- work to enhance skin appearance. An understanding of the underlying process may lead to better cosmetic formulations as well as have medical applications.

Skin cell spray key to venous leg ulcer treatment

A spray consisting of a mixture of keratinocyte and fibroblast skin cells holds promise for treatment of venous leg ulcers, show results from a phase II randomized controlled trial published in The Lancet.

New drug may be useful in treating long QT syndrome

Johns Hopkins researchers have discovered a new drug that may be useful in treating a heart rhythm condition called long QT syndrome.

Parkinson’s disease treatment: an interview with Ted Dawson

Parkinson’s disease is a disorder which usually affects people in their 60’s and older. It is caused by the loss of dopamine neurons in the brain leading to rigidity, slowness of movement, tremor, problems with balance and so forth.

New drug shows promise for Long QT syndrome

Long QT syndrome, which results from genetic mutation or certain medications, can cause the heart to beat chaotically and the affected person to die suddenly. The chaotic heartbeat is due to abnormal electrical activity in the heart. In an electrocardiogram test, this abnormality appears as a wider-than-normal QT interval, a pattern of "hills" in a map of peaks and valleys corresponding to the heart contracting and relaxing.

Human neutrophil peptide 1 effectively prevents HIV entry into cells in multiple ways

Human defensins, aptly named antimicrobial peptides, are made in immune system cells and epithelial cells (such as skin cells and cells that line the gut). One of these peptides, human neutrophil peptide 1, under certain circumstances hinders HIV infection, but exactly how it works remains unclear.

Internal clock of human skin responsible for time-based steering of repair and regeneration

A research team at Charité - Universitätsmedizin Berlin together with scientists at a company in Hamburg has now discovered that human skin has an internal clock responsible for the time-based steering of its repair and regeneration, among other things. The team published its first results from their basic research in the current issue of Proceedings of the Academy of Science (PNAS).

Promising path to Parkinson’s disease treatment

Using adult stem cells, Johns Hopkins researchers and a consortium of colleagues nationwide say they have generated the type of human neuron specifically damaged by Parkinson’s disease (PD) and used various drugs to stop the damage.

New Alzheimer's model derived from skin cells of patients may prove to be more accurate

Researchers at the Alzheimer's Association International Conference 2012 (AAIC 2012) today reported the creation of a new model of Alzheimer's derived from the skin cells of people with the disease that were reprogramed into Alzheimer's brain cells.
