Hans Clevers (Hubrecht I., UU) 1: Discovery and Characterization of Adult Stem Cells in the Gut

www.ibiology.org/development-...
Dr. Hans Clevers provides a historical perspective on the discovery of adult stem cells in the gut, and explains how his lab developed a technique to grow from a single stem cell an organoid or mini-organ, a structure that recapitulates the normal structure of the gut.
In his first talk, Dr. Hans Clevers provides a historical perspective on the discovery of adult stem cells in the gut. They identified a Wnt-dependent, rapid proliferating population of cells at the bottom of the crypt which seemed to be important for generating all epithelial cells in crypts and villi, and they hypothesized that these were gut stem cells. By using the Lgr5 gene as a marker, the Clevers’ lab confirmed that these long-lived cells were indeed the gut stem cells by showing that they were able to generate all of the cell types of the gut epithelium throughout life. Clevers characterizes the gut stem cells and its progenitors, and explains how his lab developed a technique to grow from a single stem cell an organoid or mini-organ, a structure that recapitulates the normal structure of the gut.
In his second talk, Clevers shows how one can apply what we have learned from developing gut organoids to generate mini-organs for other epithelial tissues, like liver and lung. Clevers shows that these organoids have a similar expression profile as well as structural characteristics to those observed in real tissue. In addition, he shows how this technique can be used to generate non-mammalian organoids, like the development of venom gland organoids from snake venom gland tissue. As Clevers explains, such organoids can be used to discover possible novel therapeutics, including new anti-venom serum.
In his third talk, Clevers describes how organoids can guide our understanding of disease progression in cancer. In addition, using Cystic Fibrosis and cancer as examples, Clevers shows how organoids can be used to predict therapeutic outcome in patients.
Speaker Biography:
Dr. Hans Clevers is a Principal Investigator at the Hubrecht Institute, a Professor in Molecular Genetics at the University Medical Center Utrecht, and an Oncode Investigator. He obtained his medical (1984) and doctoral (1985) degrees at the University of Utrecht. He continued his education as a post-doctoral fellow in the lab of Dr. Cox Terhorst at the Dana-Farber Cancer Institute at Harvard Medical School. In 1989, he joined the faculty at the University of Utrecht, where his lab studies the biology of Wnt signaling in development and cancer. Using Lgr5 as a marker, his lab discovered adult stem cells in the intestine, and developed a technique to grow these stem cells into epithelial organoids. Using these organoids, his lab is able to study a multitude of physiological, and pathological processes, and use organoids as a model to understand disease progression and predict drug responses.
For his scientific contributions, Clevers received the Breakthrough Prize in Life Sciences in 2013, and is an elected member of the European Molecular Biology Organization (EMBO) (1999), the Royal Netherlands Academy of Sciences (2000), the National Academy of Sciences (2014), the French Academie des Sciences (2017) and the Royal Society of London (2019).

I think a lot of people miss that this man is the founder of organoid research and confetti mice. He’s on track for a Nobel prize.

[@firSound]

This was fantastic! I'd love for iBiology to do a series on lab techniques, instrumentation used etc. Seeing techniques and instrumentation for a study like this would be invaluable, particularly if the choices or motivations for why a particular technique or method was chosen over another.

[@NeonsStyleHD]

WOW!!! You're a great speaker. As you talk I keep coming up with questions, then as soon as I do you answer it for me. Fascinating talk. Thank you :D

[@seanhuang5714]

So elegant design and elucidation of gut stem cell,thanks! Waiting for next one.

[@catherinee.422]

By far, he’s my favorite speaker alongside Edmund Fischer. I’ve been intrigued by so many facets of biology, but i’d have to say molecular and developmental biology take the cake, and he explains it so well. You can tell he’s passionate about the topic, too.

[@CONCIERTOSCL]

I expect their group get the novel prize one day!

[@thetitansfan02]

This was absolutely incredible! Also this guy is really good at explaining the concepts

[@khangluu4899]

A great speaker coupled with a great topic! Fantastic video! Thank you so much!

[@zohrehsharafian2802]

Thanks for the fantastic organoid lectures! very appreciated !

[@dpatulea]

I'm not in this field and i understood what he said. It's amazing. Good job! Lovely

[@alexandradimitriou4595]

Congratulation for your innovative work!

[@st05843]

Excellent lecture! Thank you!

[@leongjack7587]

Amazing works

[@samarths]

Wow. Explained so succinctly!

[@NeonsStyleHD]

Does this mean in this case of the Villus, that stomach cancer can be controlled by controlling this APC protein?

[@liulucy6051]

Thank you.

[@user-ec9ck9rm1r]

Thank you sir^^

[@leilagingil]

Why they didn’t use GFP for multipotency? Or tracking the cells?

[@erikals]

❤️ Awesome!

[@dhiahassen9414]

Whe i watch this guy talking , it is diffrent , i always understand

[@williambunting803]

Beautifully presented. Dutch Science is right up there.

[@leomullett3618]

I liked the clown fish at the end.
Though the research is superb

[@hraqhraq]

Every time he says Peneth Cell and my ears receives it as penicillin, my brain needs extra processing to flip it by autocorrection mechanisms

[@samarths]

23:38 🤯

[@samarths]

31:13 Why is nemo here?

[@heyyo162]

Because they couldn't find him anywhere else.

[@samarths]

WOW!! Did nature really get us here just thru natural selection? Mind blown

[@alexanderpadalka5708]

🗽

[@carknower]

I’m not a scientist, why did I watch all 30 minutes of this?

[@farvision]

Because if you watch a lot of scientific talks, you will begin to understand, and then it becomes fascinating! You might even end up being a scientist and making your own discoveries ...
