Stem Cells News and Research

RSS

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.

Research funders ask public what they really think about stem cell research

The UK's two biggest public funders of stem cell research have today launched a year-long national dialogue programme that aims to find out what the public really think about stem cell science.

Researchers find new way to transplant new blood-forming stem cells into bone marrow of mice

Researchers at the Stanford University School of Medicine have taken a small but significant step, in mouse studies, toward the goal of transplanting adult stem cells to create a new immune system for people with autoimmune or genetic blood diseases.

Scientists identify key nerve navigation pathway

Newly launched nerve cells in a growing embryo must chart their course to distant destinations, and many of the means they use to navigate have yet to surface.

New technique provides stem cells without ethical and legal constraints

In a paper to be published Nov. 22 in the online edition of the journal Science, a team of University of Wisconsin-Madison researchers reports the genetic reprogramming of human skin cells to create cells indistinguishable from embryonic stem cells.

Human pluripotent stem cells without human cloning

Two major scientific papers published this week in Science and Cell unveil a proven way to generate patient-matched human pluripotent stem cells without human cloning, and without the use of human embryos or human or animal eggs.

Advancing stem cell research and therapies while fully respecting the dignity of human life

The following statement was released by Cardinal Justin Rigali of Philadelphia, chairman of the Committee for Pro-Life Activities at the United States Conference of Catholic Bishops.

Human skin could be a new source of stem cells

A simple recipe—including just four ingredients—can transform adult human skin cells into cells that resemble embryonic stem cells, researchers report in an immediate early publication of the journal Cell, a publication of Cell Press.

Japanase scientists reprogramme human adult cells to function like pluripotent embryonic stem cells

Acclaimed stem cell researcher Shinya Yamanaka, MD, PhD, has reported that he and his Kyoto University colleagues have successfully reprogrammed human adult cells to function like pluripotent embryonic stem (ES) cells.

Stem-cell finding alters ethical controversy

When University of Wisconsin-Madison researchers succeeded in reprogramming skin cells to behave like embryonic stem cells, they also began to redefine the political and ethical dynamics of the stem-cell debate, a leading bioethicist says. R. Alta Charo, a UW-Madison professor of law and bioethics, says the scientific finding could have far-reaching effects on the social dimensions of the ongoing controversy over embryonic stem cell research.

Dyslexia expert Dr. Bruce McCandliss awarded Presidential honor

Dr. Bruce McCandliss, a psychologist at the Sackler Institute for Developmental Psychobiology and associate professor of psychology in psychiatry at Weill Cornell Medical College, has received a commendation by the President of the United States in the form of a Presidential Early Career Award for Scientists and Engineers (PECASE).

New technique enables the detection of biomolecules' dynamic reactions in a single living cell

By taking advantage of the signature frequency by which organic and inorganic molecules absorb light, the team of researchers, led by Luke Lee, professor of bioengineering and director of UC Berkeley's Biomolecular Nanotechnology Center, can determine in real time whether specific enzymes are activated or particular genes are expressed, all with unprecedented resolution within a single living cell.

Scientist who created Dolly says stem cells from skin fragments now the way to go

The scientist who created Dolly the sheep says he is abandoning the cloning of human embryos in stem cell research.

Woman's menstrual cycle provides newly discovered type of stem cell

The cells which thicken the womb wall during a woman's menstrual cycle contain a newly discovered type of stem cell, and could be used in the treatment of damaged and/or old tissue, according to research published in the online open access publication, Journal of Translational Medicine.

Stem cells from cloned monkeys - a breakthrough or an ethical nightmare?

In an important breakthrough scientists in the United States have cloned monkey embryos to create embryonic stem cells.

Human embryonic stem cells derived from preimplantation genetically diagnosed embryos

A human stem cell line derived from embryos that were identified by preimplantation genetic diagnosis (PGD) to carry the mutation for fragile X syndrome has provided an unprecedented view of early events associated with this disease.

Telomerase enzyme structure provides significant new target for anti-cancer therapies

Inappropriate activation of a single enzyme, telomerase, is associated with the uncontrollable proliferation of cells seen in as many as 90 percent of all of human cancers. Since the mid-1990s, when telomerase was first identified in human tumors, scientists have eyed the enzyme as an ideal target for developing broadly effective anti-cancer drugs.

Neurofibromatosis 1 gene drives pivotal decision in early brain development

A gene linked to pediatric brain tumors is an essential driver of early brain development, researchers at Washington University School of Medicine in St. Louis have found.

Placenta uses a cloaking device similar to that used by parasites

The placenta uses a cloaking device similar to that used by parasites to avoid detection by the mother's immune system. MRC funded scientists looking to develop a diagnostic test for pre-eclampsia, a major and potentially fatal cause of fetal and maternal illness, made the amazing discovery which could have far reaching implications.

Researchers image a biomarker of neurogenesis

Mirjana Maletic-Savatic, M.D., Ph.D, and co-investigators from Stony Brook University Medical Center, Brookhaven National Laboratory and Cold Spring Harbor Laboratory have discovered a way to image a biomarker of neural stem and progenitor cells (NPCs) in the living human brain.
