TOP STORY

Multilineage-Differentiating Stress-Enduring (Muse) Cells Are a Primary Source of Induced Pluripotent Stem Cells in Human Fibroblasts
Results demonstrate that in adult human fibroblasts a subset of preexisting adult stem cells whose properties are similar in some respects to those of induced pluripotent stem (iPS) cells selectively become iPS cells, but the remaining cells make no contribution to the generation of iPS cells. [Proc Natl Acad Sci U S A]

SCIENCE NEWS

Scientists Turn Human Skin Cells Directly into Neurons, Skipping iPS Stage
Human skin cells can be converted directly into functional neurons in a period of four to five weeks with the addition of just four proteins, according to a study. [Press release from Stanford University School of Medicine discussing online prepublication in Nature]

Researchers Move Step Closer to Using iPS Cells in Regenerative Medicine
A group of researchers have succeeded in producing a new type of iPS cells that is less carcinogenic, marking a step closer toward the use of iPS cells in regenerative medicine, it has been announced. [Press release from The Mainichi Daily News discussing online prepublication in Cell Stem Cell]

Researchers Discover Key Molecule for Stem Cell Pluripotency
Researchers have discovered what enables embryonic stem cells to differentiate into diverse cell types and thus to be pluripotent. [Press release from Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch discussing online prepublication in EMBO Reports]

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)

Induction of Human Neuronal Cells by Defined Transcription Factors
Researchers show that three transcription factors (Brn2, Ascl1 and Myt1l) can generate functional neurons from human pluripotent stem cells as early as 6 days after transgene activation. [Nature]

Reprogramming of Mouse and Human Cells to Pluripotency Using Mature MicroRNAs
Scientists show that it is possible to reprogram mouse and human cells to pluripotency by direct transfection of mature double-stranded microRNAs. [Cell Stem Cell]

Rapamycin and Other Longevity-Promoting Compounds Enhance the Generation of Mouse Induced Pluripotent Stem Cells
Investigators report that inhibition of the mTOR (mammalian target of rapamycin) pathway by rapamycin or PP242 enhances the efficiency of reprogramming to induced pluripotent stem cells. [Aging Cell]

Evidence for the Transmission of Neoplastic Properties from Transformed to Normal Human Stem Cells
Here, using a uniquely developed in vitro co-culture system for human embryonic stem cells, investigators examined the interactions between transformed and normal human stem cells. [Oncogene]

E-Cadherin Is Crucial for Embryonic Stem Cell Pluripotency and Can Replace OCT4 During Somatic Cell Reprogramming
Scientists report new functions of the cell-adhesion molecule E-cadherin in murine pluripotent cells. [EMBO Rep]

A System for Imaging the Regulatory Noncoding Xist RNA in Living Mouse Embryonic Stem Cells
To understand localization of Xist over one X chromosome better investigators aimed to develop a system for investigating Xist in living cells. [Mol Biol Cell]

Calcium Homeostasis in Human Induced Pluripotent Stem Cell-Derived Cardiomyocytes
Researchers investigated the calcium handling properties of human induced pluripotent stem cell-derived cardiomyocytes and compared with those from human embryonic stem cells. [Stem Cell Rev]

The Retinol Signaling Pathway in Mouse Pluripotent P19 Cells
Scientists investigated whether the mouse pluripotent P19 cell metabolizes retinol to all-trans-retinoic acid and thus can be used in a cell-based screen for disruptors of the pathway. [J Cell Biochem]
