NEW ROCHELLE, N.Y., Feb. 2 /PRNewswire/ -- Since the cloning of Dolly the Sheep over a decade ago, somatic cell nuclear transfer (SCNT) has been considered a promising way to generate human, patient-specific stem cells for therapeutic applications. The shortage of human donor eggs has led to efforts to substitute animal oocytes. However, a new study published online ahead of print in the Volume 11, Number 2, 2009 issue of Cloning and Stem Cells, a peer-reviewed journal published by Mary Ann...

New study questions ability of human-animal hybrids to generate stem cells WORCESTER, Mass., Feb. 2 /PRNewswire-FirstCall/ -- Advanced Cell Technology, Inc. (OTC Pink Sheets: ACTC) and its collaborators reported today that human oocytes (or 'eggs') have the capacity to extensively reprogram adult human cells. The research, which appears online ahead of print in the journal Cloning and Stem Cells (Editor-in-Chief: Sir Ian Wilmut; published by Mary Ann Liebert, Inc.) demonstrates that...

Whitehead Institute researchers have greatly simplified the creation of so-called induced pluripotent stem (iPS) cells, cutting the number of viruses used in the reprogramming process from four to one. Scientists hope that these embryonic stem-cell-like cells could eventually be used to treat such ailments as Parkinson's disease and diabetes.The earliest reprogramming efforts relied on four separate viruses to transfer genes into the cells' DNA--one virus for each reprogramming gene (Oct4,...

U.S. scientists say they have identified compounds for stem cell production from adult cells, moving medicine closer to the reprogramming of general cells. Scripps Research Institute scientists said they screened known drugs and identified small molecules that could replace conventional reprogramming genes. They said the process they developed offers a new way to generate stem cells from fibroblasts, a general cell type that is abundant and easily accessible from various tissues, including...

By MARK JOHNSON Japanese scientists have demonstrated a new way to reprogram cells without viruses, an important advance toward the goal of one day turning our own cells into a powerful tool to fight a wide range of diseases. The new technique, reported Thursday in the journal Science, appears to be both safer and simpler than previous methods, bypassing the cancer risk associated with using viruses and genes that remain inside a cell. The Japanese team, led by Shinya Yamanaka of Kyoto...

By Patricia Reaney LONDON (Reuters) - A gene named after the mythical Celtic land of the ever young could help explain how to reprogram adult cells into embryonic stem cells to treat diseases, researchers said on Wednesday. They discovered that the gene called Nanog helped to transform adult mouse cells into embryonic stem cells after cell fusion -- when two cells are combined to form a hybrid. "The effect of Nanog is remarkable. All the hybrid cells became fully converted to...

With the advent of nuclear-transfer cloning, it is now possible to produce mice from the nuclei of differentiated cells, such as peripheral blood lymphocytes and olfactory sensory neurons. However, unlike most other clones, those formed with the nuclei of differentiated cells were generated by a two-step nuclear-transfer procedure that might allow the donor genome further reprogramming. Thus, these findings do not settle the question of whether the egg cytoplasm can itself reprogram a fully...
