Monkey-pig chimeras pub discouraging for similar human research toward organ transplants

pig-monkey-chimera-that-was-born-but-died

Michael Le Page over at The New Scientist reports on a new paper describing the birth of monkey-piglet chimeras. Unlike most such primate embryo chimeras formed in research in the past, these were allowed to be born. A litter of ten from the new monkey-pig research, two of which were chimeras, all rather quickly died …

Weekly reads: CRISPR sickle cell, Parkinson’s, pig-human chimera concerns

CRISPR gene editing

CRISPR gene editing has made rapid progress heading from bench to bedside. Perhaps the fastest has been its progress toward clinical use to combat sickle cell disease. We’ll start with a new paper on one major effort here. CRISPR gene editing. This process often involves cutting DNA, which then can be used as an opening to …

Vivek Ramaswamy & his surprising stem cell start

Vivek Ramaswamy

Many of us first became aware of Vivek Ramaswamy as a Republican candidate for President. He was most well-known prior to that as a biotech leader. Given that biotech background, I decided to learn more about him. Surprisingly, his biomedical efforts may have started with stem cells. That caught my attention. This was way back during …

Stem cells & the philosopher’s stone, P53, thyroid organoids

philosopher's stone

I hadn’t remembered the history of the philosopher’s stone until reading a new review article about stem cells and aging. Here’s the article. Is the philosopher’s stone to rejuvenate blood stem cells an epigenetic regulator? Nature Aging. This preview kind of piece discusses how inhibiting a specific factor called PHF6 can “rejuvenate” HSCs in mice. …

Weekly reads: chimera cat vs. chimeric rat, cheap sequencing, more

Venus, cat chimera

When you are a stem cell biologist and especially if you do a blog, you sometimes run across very strange things like a chimera cat. In this case, I stumbled on the whole topic of chimeric cats because I was searching for info on chimeric rats on Google. Of course, I was. It’s kind of …

Monkey human embryo chimera Cell paper: exciting, ethically complex direction

human embryo chimera

A new Cell paper from an international team led by Juan Carlos Izpisua Belmonte pushes human embryo chimera embryo research further than ever before. It is both exciting work and raises many complex bioethics questions at the same time. What is a human embryo chimera? By way of background, chimeric human embryos contain a mixture …
