Genes That Control Embryonic Stem Cell Fate Identified

Scientists have identified about two dozen genes that control embryonic stem cell fate. The genes may either prod or restrain stem cells from drifting into a kind of limbo, they suspect. The limbo lies between the embryonic stage and fully differentiated, or specialized, cells, such as bone, muscle or fat.

Washington, July 11 : Scientists at the University of California, San Francisco say that they have identified about two-dozen genes that control embryonic stem cell fate.

Scientists create 20 disease-specific stem cell lines

(PhysOrg.com) -- Harvard Stem Cell Institute researcher George Q. Daley, associate director of the Stem Cell Program at Children's Hospital Boston, has with HSCI colleagues Chad Cowan and Konrad Hochedlinger of Massachusetts General Hospital produced a robust new collection of disease-specific stem cell lines, all of which were developed using the new induced pluripotent stem cell (iPS) technique. The work is described in a paper published in today's online edition of the journal Cell.

Boston, Mass, Aug. 7, 2008 – Harvard Stem Cell Institute researcher George Q. Daley, MD, PhD, also associate director of the Stem Cell Program at Children's Hospital Boston, and HSCI colleagues Konrad Hochedlinger and Chad Cowan have produced a robust new collection of disease-specific stem cell lines, all of which were developed using the new induced pluripotent stem cell (iPS) technique. The paper is being published in the August 6 on-line edition of the journal Cell.

Human Stem Cell Research: Stepping It Up a Notch

Researchers at Johns Hopkins have discovered that the Notch protein helps human embryonic stem cells “decide� their own fate, a finding which may eventually be useful in programming cells for the development of stem cell therapies. Their results are reported in the May 2008 issue of Cell Stem Cell.

Human embryonic stem cells developed from 4-cell embryo; world first may lessen ethical concerns

Barcelona, Spain: For the first time in the world scientists have succeeded in developing human embryonic stem cells (hESCs) from a single cell, or blastomere, of a 4-cell stage embryo, the 24th annual conference of the European Society of Human Reproduction and Embryology heard today (Wednesday 9 July). Dr. Hilde Van de Velde, from the Vrije Universiteit Brussel (VUB), Brussels, Belgium, said that their research meant that it might be possible in the future to produce hESC lines at an earlier stage without destroying the embryo.

Protein's role in stem cells fate studied

BALTIMORE, July 22 (UPI) -- Notch protein in human embryonic stem cells helps cells "decide" their own fate, which may be useful in stem cell therapy development, U.S. researchers said.

Lytic Transglycosylase MltB of Escherichia coli and Its Role in Recycling of Peptidoglycan Strands of Bacterial Cell Wall

The cell wall is an indispensable structure for the survival of bacteria and a target for antibiotics. Peptidoglycan is the major constituent of the cell wall, which is comprised of backbone repeats of N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM). A peptide stem is appended to the NAM unit, which in turn experiences cross-linking with a peptide from another peptidoglycan in the final steps of cell wall assembly. In the normal course of bacterial growth, as much as 60% of the parental cell wall is recycled, a process that is not fully understood. A polymeric cell wall is fragmented by the family of lytic transglycosylases, and certain key fragments are transported to the cytoplasm for recycling. The genes for the six known lytic transglycosylases of Escherichia coli were cloned, and the enzymes were purified in this study.

Ronin An Alternate Control For Embryonic Stem Cells

Like the masterless samurai for whom it is named, the protein Ronin chooses an independent path, maintaining embryonic stem cells in their undifferentiated state and playing essential roles in genesis of embryos and their development, said Baylor College of Medicine researchers who reported on this novel cellular regulator in the current issue of the journal Cell.

Standards In Stem Cell Research

Standards in stem cell research help both scientists and regulators to manage uncertainty and the unknown, according to new research funded by the Economic and Social Research Council. Efforts to standardise practices across different labs is, however, a balancing act where the autonomy of scientists and fragility of living material need to be weighed against the need for comparable data.
