What’s new in the stem cell, cell therapy, and regenerative medicine world as well as biomedical science more generally including cancer? There’s quite a bit of news as reflected in media pieces and new pubs. Today’s post is focused on pubs that just came out. For last week’s recommended reads see here. Oct4-Sox2 Nucleosome Binding & Impact in mESCs This is one of my favorite papers of 2020 so far, coming to us from Science. Mechanisms of OCT4-SOX2 motif readout on nucleosomes. I knew from …Read More

One of the highlights of Day 1 of #ISSCR2018 for me so far was the talk by Lorenz Studer (Co-Founder of BlueRock) on the use of human embryonic stem cell (HESC)-derived dopamine neurons for Parkinson’s Disease. Note that for this post and if I have time any others on this meeting, they are probably going to be somewhat stream of consciousness notes from the talks and may have some outlined points rather than sentences. I have some questions or notes for myself that I …Read More

A new paper focused on human and other chimeras just came out today in Cell reporting a number of findings, but most strikingly successful generation of human-pig chimeras in utero. The paper, entitled, “Interspecies Chimerism with Mammalian Pluripotent Stem Cells” describes various chimeras including mouse-rat ones, although those have previously been reported. This work comes from a team led by Juan Carlos Izpisua Belmonte including first author Jun Wu, and also with important contributions from Pablo Ross’s lab here at UC Davis The big news …Read More

What’s the deal with the tension between José Silva and Jacob Hanna over pluripotency? Researchers probing how to reprogram cells into powerful stem cells (induced pluripotent stem cells or IPSCs) and what the molecular mechanisms are behind this process have become entangled in a conflict. Of course over the years scientists including stem cell scientists have had their share of disagreements and debates in the past including heated ones, but this reprogramming clash has taken it up a notch beyond past ones and has some unique elements …Read More
