SCIENCE NEWS

Growing Cartilage from Stem Cells
Using adult stem cells from bone marrow and skin as well as human embryonic stem cells, researchers have grown cartilage tissue in the lab. [University of California - Davis, Davis]

Fate Therapeutics Announces Creation of Small Molecule Platform for Commercial Scale Reprogramming
The discoveries represent a more than 200 fold improvement in reprogramming efficiency and reduce the reprogramming period to two weeks as compared to methods using only the four reprogramming factors (Oct 3/4, Sox2, Klf4 and c-Myc). [Fate Therapeutics, Inc., La Jolla]

What Drives Our Genes? Salk Researchers Map the First Complete Human Epigenome
Researchers at the Salk Institute provide the first detailed map of the human epigenome, the layer of genetic control beyond the regulation inherent in the sequence of the genes themselves. [Salk Institute for Biological Studies, La Jolla]

'Spaghetti' Scaffolding Could Help Grow Skin in Labs
Researchers at the University of Bristol have taken a novel biologically-inspired track for the production of synthetic biocompatible hydrogels, which could be used to grow new tissues tailored to the needs of individual patients. [University of Bristol, Bristol]

Scientists Develop Novel Method to Generate Functional Hepatocytes for Drug Testing
Scientists have for the first time produced liver cells from adult skin cells using the induced pluripotent stem cell technology. [MRC Centre for Regenerative Medicine, Edinburgh]

CURRENT PUBLICATIONS

Generation of Medaka Fish Haploid Embryonic Stem Cells
Here, the researchers generated gynogenetic medaka embryos and obtained three haploid ES cell lines, elusive for culture that retained pluripotency and competitive growth. [Science]

Human Embryonic Stem Cell Lines Derived from Single Blastomeres of Two 4-cell Stage Embryos
To investigate potency at the 4-cell stage, this study aimed to derive pluripotent human embryonic stem cells from single blastomeres. [Hum Reprod]

Inhibition of Caspase-mediated Anoikis is Critical for bFGF-sustained Culture of Human Pluripotent Stem Cells
By using the defined mTeSR1 medium and collecting freshly detached cells, the researchers found here that human pluripotent stem cells including embryonic stem cells and induced pluripotent stem cells are subject to constant anoikis in culture. [JBC]

Identification of Targets of Prox1 During in Vitro Vascular Differentiation from Embryonic Stem Cells: Functional Roles of HoxD8 in Lymphangiogenesis
This study identified FoxC2 and angiopoietin-2 (Ang2), which play important roles in the maturation of lymphatic vessels, as novel targets of Prox1 in mouse embryonic-stem-cell-derived endothelial cells. [J Cell Sci]

HOXB4-Transduced Embryonic Stem Cell-Derived Lin-c-kit+ and Lin-Sca-1+ Hematopoietic Progenitors Express H60 and Are Targeted by NK Cells1
In this study, the researchers demonstrate that hematopoietic progenitor cells derived from mouse ES cells ectopically expressing HOXB4 fail to engraft long-term in the presence of NK cells. [J Immunol]

Gene Silencing in Human Embryonic Stem Cells by RNA Interference
The prospects of combining RNAi and HESC manipulation for both basic research and future therapies are reviewed. [Biochem Biophys Res Commun]

Cripto-1 Is Required for Hypoxia to Induce Cardiac Differentiation of Mouse Embryonic Stem Cells
In the present study, the effect of low levels of oxygen, which occurs naturally in rapidly growing tissues, on Cripto-1 expression in mouse embryonic stem cells and in human embryonal carcinoma cells was investigated. [Am J Pathol]

p75 Neurotrophin Receptor is Involved in Proliferation of Undifferentiated Mouse Embryonic Stem Cells
In the present work the researchers investigated the expression of p75NTR and Trks in totipotent and pluripotent cells, the mouse pre-implantation embryo and embryonic stem and germ cells. [Exp Cell Res]
