Toward the end of each year, I make stem cell & regenerative medicine predictions for the coming year. It’s a fun tradition here on The Niche that goes way back. The stem cell field has changed dramatically as reflected in each year’s predictions. Here’s a list of past predictions with my grades of how they …

It’s that time of year again when I grade my previous year’s predictions for the stem cell & regenerative medicine space. Overall, I did better than a typical year. I give the 2022 predictions an A- overall. This exercise can be kind of fun but also humbling. For example, I tend to be too optimistic …

Something called the 14-day rule on growing human embryos in the lab helped keep a tough question in check for a long time: when is it ethically wrong or just practically unwise to continue growing a human embryo for research? There is no good answer based on science or anything else. ISSCR moves beyond strict …
Risks rise as ISSCR drops strict 14-day rule on human embryo growth in the lab Read More »
A human embryo model is a laboratory-produced collection of living cells that has some key things in common with real human embryos. They are made from pluripotent stem cells, which include embryonic stem cells and induced pluripotent stem cells or iPS cells. This research is both exciting and ethically complicated, raising some difficult questions. Embryo …
This was an unusual week in that three papers in a sense collided together related to embryo production and growth, raising new research possibilities but also serious ethical questions. New research: what is an embryo & what is not? The first two Nature papers reported generating the most realistic models of human embryos from scratch …

Here are some recommended weekend science reads and links including stem cells, CRISPR, and clones. Woo-Suk Hwang & his dog clones…all started with Snuppy (pictured): Disgraced Scientist Clones Dogs, And Critics Question His Intent.Now in 2020, I wonder where Hwang is and what is he doing? I’m going to look into it. Human gene editing …
A question that has come up with advances in stem cell technology: could same-sex couples have their own biological children? Since Shinya Yamanaka reprogrammed first mouse and then human ordinary cells into powerful pluripotent stem cells, termed induced pluripotent stem (iPS) cells, back in 2006-2007 many new research avenues have opened up. The impossible suddenly …
TGIF: I’m working on an R01, but I still try to find time to read a wide variety of papers. Below are the science pubs that I’m hoping to get to this weekend. Less Myc, longer “health span” Cell paper from Sedivy Lab. ESC Histone H3.3 nucleosomal functions Epigenetics & Chromatin paper from Keji Zhao Lab. Human …

A heated series of discussions on stem cell publications is ongoing on the Post-publication review (post-pub) website, PubPeer, which has been called by a PubPeer user “The stem cell shoot out“. This “shoot out” goes well beyond the one page on PubPeer. It is notable to see that the authors of the papers that are the …

Nominations for Stem Cell Person of the Year 2013 closed last night and I ended up with a remarkable list of 30 nominees. I have included a few sentences about each one below, often taking verbiage directly from the nominator. The online voting on these nominees will start soon. The top vote getters will move …
