Stem Cells News and Research

Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Thermo Fisher Scientific creates breakthrough gene-silencing tool

Thermo Fisher Scientific Inc. has developed a breakthrough gene-silencing tool that greatly simplifies RNA- interference (RNAi) technology and eliminates barriers associated with previous cellular delivery methods.

Post brain injury: New nerve cells originate from neural stem cells

Most cells in the human brain are not nerve cells, but supporting cells (glial cells).

Turning off rogue macrophages

University of Pennsylvania scientists studying macrophages, the biological cells that spring from white blood cells to eat and destroy foreign or dying cells, have discovered how these "policemen" differentiate between friend and foe.

Cell therapy for rejuvenating aged brain by injection of human umbilical cord blood

When human umbilical cord blood cells (UCBC) were injected into aged laboratory animals, researchers at the University of South Florida (USF) found improvements in the microenvironment of the hippocampus region of the animals' brains and a subsequent rejuvenation of neural stem/progenitor cells.

MIT develop inexpensive cell-sorting method

Capitalizing on a cell's ability to roll along a surface, MIT researchers have developed a simple, inexpensive system to sort different kinds of cells - a process that could result in low-cost tools to test for diseases such as cancer, even in remote locations.

Improved method for genetically manipulating human embryonic stem cells

UC Irvine researchers have discovered a dramatically improved method for genetically manipulating human embryonic stem cells, making it easier for scientists to study and potentially treat thousands of disorders ranging from Huntington's disease to muscular dystrophy and diabetes.

Molecular alliance that sustains embryonic stem cell state

One of the four ingredients in the genetic recipe that scientists in Japan and the U.S. followed last year to persuade human skin cells to revert to an embryonic stem cell state, is dispensable in ES cells, thanks to the presence of a molecular alliance between a specific group of key proteins known as transcription factors, a research team led by the Genome Institute of Singapore (GIS) under the Agency for Science, Technology and Research (A*STAR) reports in the current issue of Nature Cell Biology.

Watery pools in bone marrow key to psoriatic arthritic damage

Researchers have learned more about how a leading drug prevents certain types of arthritis from eating away at bone, according to a study published in the March edition of the Annals of the Rheumatic Diseases.

Cigarette smoke prevents stem cells from becoming cartilage

A toxic pollutant spread by oil spills, forest fires and car exhaust is also present in cigarette smoke, and may represent a second way in which smoking delays bone healing, according to research presented at the annual meeting of the Orthopaedic Research Society in San Francisco.

Stem cell funding for Parkinson’s disease

The Parkinson's Disease Society (PD) has announced funding of £170k to the University of Bristol for research into how to make stem cells produce dopamine and live longer after they have been transplanted into animals.

Protein in embryonic stem cells control malignant tumor cells

A protein that governs development of human embryonic stem cells (hESCs) also inhibits the growth and spread of malignant melanoma, the deadliest skin cancer, Northwestern University researchers have discovered.

Tiny RNA molecule found to help create skin's protective barrier

Every minute, 30,000 of our outermost skin cells die so that we can live. When they do, new cells migrate from the inner layer of the skin to the surface of it, where they form a tough protective barrier.

Adult stem cell changes underlie Hutchinson-Gilford Progeria syndrome associated with accelerated aging

Adult stem cells may provide an explanation for the cause of a Hutchinson-Gilford Progeria Syndrome (HGPS), a rare disease that causes premature aging in children, according to researchers at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH).

New discovery on programmed cell death

Investigators at St. Jude Children's Research Hospital have discovered a dance of proteins that protects certain cells from undergoing apoptosis, also known as programmed cell death. Understanding the fine points of apoptosis is important to researchers seeking ways to control this process.

Adult stem cells may be beneficial for certain cardiovascular disorders and autoimmune diseases

A review of previously published research suggests that stem cells harvested from an adult's blood or marrow may provide treatment benefit to select patients for some autoimmune diseases and cardiovascular disorders, according to an article in the February 27 issue of JAMA: The Journal of the American Medical Association.

Notch protein plays a critical role in bone formation

Notch, a protein known to govern the determination of cell differentiation into different kinds of tissues in embryos, plays a critical role in bone formation and strength later in life, said researchers from Baylor College of Medicine in Houston in a report that appears online today in the journal Nature Medicine.
