Weekly reads: hydra heads, iblastoids, new 8-year grants

Grant writers handbook, grants cartoon

What if you could get 8-year grants to do whatever biomedical research you wanted? This sounds like a dream for many of us in the life sciences, but the first news item this week is all about such a potential new funding approach. The item especially caught my eye as I’m going to be doing …

New lab-grown blastoids are strikingly similar to human embryos

blastoids nature paper figure 2

A new word has been added to the lexicon of human stem cell research – blastoids, aka “blastocyst-like structures.” Unlike the familiar three-layered embryo that emerges during the third week of prenatal development, the earlier blastocyst resembles a fluid-filled soccer ball, with a smear of cells on the interior face destined to develop into the …

Weekly reads: stembryos or human embryo models, new Macchiarini sentence

stembryos, embryo models Monash

Researchers have been making stem cell-based embryo models for years now and a few folks have taken to calling these “stembryos.” Other names like gastruloids and blastoids are sometimes used too. “Embryo models” might be the simplest and best name. The embryo model research has advanced relatively quickly from very basic, not very organized structures …

Grading my 2022 regenerative medicine predictions

stem-cell-crystal-ball-300x3001

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 …

‘We don’t want to freak people out’: about that Jacob Hanna human embryo model startup

Jacob Hanna Renewal Bio

Stem cell biologist Jacob Hanna has a new startup called Renewal Bio. Its goal is to harvest cells or tissues from human embryo or fetus models for clinical use. I believe that their commercial ambitions have so far outstripped careful thought and discussion in the broader community of researchers. There are major risks here for …

Is 2022 going to be any better than 2020 or 2021 when it comes to things in general or for biomedical science? Related to the pandemic? It’s too soon to say but if I had to guess right now I’d venture an optimistic view that overall it’s going to be somewhat better by the end …

16 predictions for stem cells & regenerative medicine in 2022

regenerative medicine, stem cells 2021

The last few years in the stem cell and regenerative medicine arena have been complicated in many ways. Variables like surging stem cell clinics and COVID have made predictions harder.  Even so, trying to make predictions is useful and it’s fun to go over past year’s predictions. You can see my scorecard on my 2021 …

Risks rise as ISSCR drops strict 14-day rule on human embryo growth in the lab

mouse embryos grown outside the lab

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 …
