Chinese Scientists Discover Marker Indicating the Developmental Potential of Stem Cells
Researchers in China are reporting that they have found a way to determine which somatic cells, or differentiated body cells, that have been reprogrammed into a primordial, embryonic-like state are the most viable for therapeutic applications. [Press release from EurekAlert! discussing online prepublication in the Journal of Biological Chemistry]



Tohoku University Team Discovers New Type of Stem Cells in Human Skin, Bone
A research team from Tohoku University has discovered a new type of pluripotent stem cell in the skin and bone marrow of adults, providing a possible third source of stem cells after embryonic stem cells and human-made induced pluripotent stem cells. [Press release from The Mainichi Daily News discussing online prepublication in Proceedings of the National Academy of Sciences USA]

Histone Deacetylase 1 (HDAC1), but not HDAC2, Controls Embryonic Stem Cell Differentiation
This genetic study of HDAC1 and HDAC2 in embryonic stem cells, which mimic the embryonic epiblast, has identified a unique requirement for HDAC1 in the optimal activity of HDAC1/2 corepressor complexes and cell fate determination during differentiation. [Proc Natl Acad Sci U S A]

A Role for Borg5 During Trophectoderm Differentiation
Researchers report that differentiation of embryonic stem cells toward trophectoderm is accompanied by enhanced actin protrusion and cell motility that require up-regulation of Borg5. [Stem Cells]

The Transcription Factor TCFAP2C/AP-2Gamma Cooperates with CDX2 to Maintain Trophectoderm Formation
Researchers report that the transcription factor Tcfap2c is expressed at a high level in the trophectoderm and is able to induce trophoblast fate in embryonic stem cells. [Mol Cell Biol]

Activation of the Imprinted Dlk1-Dio3 Region Correlates with Pluripotency Levels of Mouse Stem Cells
In this study, investigators identified a conserved imprinted region of the mouse genome, the Dlk1-Dio3 region, which was activated in fully pluripotent mouse stem cells but repressed in partially pluripotent cells. [J Biol Chem]

Repression of Retrotransposal Elements in Mouse Embryonic Stem Cells is Primarily Mediated by DNA Methylation-Independent Mechanism
To determine whether intracisternal A-Particles (IAP) is also repressed in pluripotent stem cells by DNA methylation, researchers examined IAP expression in demethylated mouse embryonic stem cells and epiblast-derived stem cells. [J Biol Chem]

Variation in Hematopoietic Potential of Induced Pluripotent Stem Cell Lines
Researchers compare differentiation capacity of six induced pluripotent stem lines into mesodermal cells and hematopoietic cells through embryoid body formation. [Stem Cell Rev]

Alternative Sources of Pluripotent Stem Cells: Ethical and Scientific Issues Revisited
Ethically uncompromised stem cells, such as those derived by direct reprogramming or from germ-cell precursors are likely to yield important advances in stem cell research, and move the field rapidly towards clinical applications. [Stem Cells Dev]

Rederivation of Transgenic Mice from Induced Pluripotent Stem Cells Derived from Frozen Tissue
This study provides conclusive evidence that, as a practical matter, frozen tails and fibroblasts can be used as an effective and reliable alternative to frozen germplasm and embryonic stem cells for the storage, maintenance, and distribution of genetically-altered mutant mice. [Transgenic Res]

Derivation and Long-Term Culture of Human Parthenogenetic Embryonic Stem Cells Using Human Foreskin Feeders
This study indicates that homologous human fibroblasts can be used as feeder cells to support not only the propagation, but also the derivation of embryonic stem cells, and this should facilitate studies of therapeutic cloning for research and clinical applications. [J Assist Reprod Genet]

Preimplantation Mouse Embryo Selection Guided by Light-Induced Dielectrophoresis
Researchers present a method that exploits the scaling electrical properties of pre-transfer embryos to quantitatively discern embryo developmental maturity using light-induced dielectrophoresis. [PLoS One]


Einstein Receives $10 Million National Institutes of Health Grant to Expand Stem Cell Research Facilities
Albert Einstein College of Medicine of Yeshiva University has been awarded $10 million from the National Institutes of Health to expand its stem cell research capabilities. [Albert Einstein College of Medicine Press Release]

Regenerative Medicine Company Wants Biobusiness Center Space
A start-up biotech company will seek Rochester City Council approval to put a manufacturing facility in the Minnesota Biobusiness Center. [The Post-Bulletin]

Florida Biotech Research Money in Jeopardy
Florida researchers could lose $50 million in biomedical research funding due to the state’s $3 billion budget deficit. [Orlando Business Journal]

Quebec Biotechs in Tailspin
Once Canada’s envy, and in the same league as Boston and San Francisco, Quebec’s biotechnology industry is a shadow of its former self and in danger of disappearing, observers say. [The Gazette]


Stem Cell Funding in Sight
Two of the most widely used embryonic stem cell lines could be just weeks away from being eligible for United States federal funding. [Obama Administration, United States]

Obama Picks Pragmatists for New Bioethics Panel
President Barack Obama named the members of his bioethics commission – headed by two university presidents. [National Bioethics Commission, United States]
