Here in the U.S. we just had our big Thanksgiving holiday, but science goes, stem cells keep growing and needing attention, and it’s another weekend chance to catch up on our paper reading. Here’s this weekend edition of recommended reads including news items and pubs. From Cell Stem Cell: Single-Cell Transcriptome Analysis of Uniparental Embryos Reveals Parent-of-Origin Effects on Human Preimplantation Development. and another there on stem cell machinery in cancer: Humanized Stem Cell Models of Pediatric Medulloblastoma Reveal an Oct4/mTOR Axis that Promotes Malignancy. …Read More

CRISPR and IPS cells are two of my favorite things so when they come together as in a cool, new paper from Sheng Ding’s lab, I’m excited to read it and curious as to what the scoop is. Since 2006-2007 when mouse and human reprogramming were first reported, many different methods have been explored to make induced pluripotent stem (IPS) cells. Along the way we’ve all learned quite a lot about how pluripotency is regulated, whether it is in the context of maintenance or …Read More

A new Cell paper from Juan Carlos Izpisua Berlmonte’s group has made headlines about anti-aging across the globe because it suggests that the four core induced pluripotent stem cell (IPSC) factors use by Shinya Yamanaka to make IPSC can reverse aging. I’ve pasted the graphical abstract from the paper below and done a quick journal club style overview based on a quick skim of the paper. Some of the media headlines are rather dramatic on this story. For instance, in a story on it over at STAT …Read More
