Carla Kim & Hans Clevers talks on organoids at #ISSCR2015

liver-organoid

Organoids are pretty big in stem cells right now with the last couple of years having attracted a lot of media attention on mini lungs, mini brains, mini kidneys, mini guts and more, giving the impression that scientists know how to specify and organise cells into mini functional organs in the lab. Organoids have become …

If I only had a brain: brain organoids from pluripotent stem cells

In a first for the field, scientists have used human pluripotent stem cells to grow miniature brain-like structures (brain organoids) in a dish in a lab (see beautiful image of one of these “mini-brains” at left from the paper). This exciting, pioneering feat, accomplished by a team from the Austrian Academy of Science in Vienna …

H3f3a, histone H3.3, knockout

It’s always exciting when your lab has a new paper and my team just published a study knocking out the H3f3a gene in mice, which codes for histone H3.3 protein. We found that loss of this gene leads to lethality at a late stage of embryonic development. There were also indications of more specific phenotypes …

2023 stem cell & regenerative medicine predictions

stem cell predictions

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 …

Funny autocorrect fails in STEM: the gremlin organdy fiasco

Germline gremlins, funny autocorrect fails

Today’s post is on the lighter side with some humor on funny autocorrect fails related to science. It’s surprising sometimes how far certain tools can lag behind cutting-edge science. Spellcheck tools are useful, of course, but they don’t always know what to do with STEM words. The same is true of tools like Grammarly, although it …

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 …

Weekly stem cell reads: aging & cells, iPS cell mutations, gut, more

Stem cells aging

Does aging do something to time so it seems like as you get older that time goes by faster? Remember as a little kid when summer seemed to last forever and car rides could be agonizingly long? I’ve heard two theories on this. One is that the brain’s baseline of activity slows down with aging …

‘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 …

Weekly science reads: Macchiarini trial, somites, CRISPR babies

organoids with somites, cool science

This has been one of those weeks where I spent some time thinking about taking risks in science. How much risk one should take? Risks can come in many forms. It could be at the core level at the bench doing specific experiments and not others. There’s risk in clinical trials, and even in advocacy. Sometimes …

fibroblasts stained

It seems like the field of cell biology has mixed feelings about fibroblasts so I’m going to start off there with the recommended reads. But first, check out our stem cell YouTube channel as we are steadily heading toward 500 subscribers and 30,000 views. Please subscribe. I’ve pasted one of our top videos below, which …
