23. Stem Cells

[@ao4618]

Wow, I’m amazed at how amazing her board writing is. Just beautiful!!

[@funkyblanket15]

I like the old school way of writing on the board.

[@wuvliving8083]

I however would have liked if they mentioned a bit of how stem cells are being used to cure aging. Some deep conversations happening at the healthspan discord server (discord.gg/ftSbffu) I'm just overwhelmed that aging might actually be cured soon.

[@dannyboy5967]

Me too. However it also distracts me with ASMR---making me feel sleepy.

[@TheR971]

Her kind of axiomatic approach to the topic combined with the blackboard makes it feel like a math lecture. Good stuff!

[@deinonychus5463]

Foregen wants to regenerate male foreskin with all specialized structures, if you want to know more about it : www.foregen.org

[@Emalbee]

She does too. She writes so hard to make that sound.

[@ahsanashraf4385]

The explanation is simply lovely. I can't thank the professor enough. Thanks for this excellent lecture.

[@awm640]

I am 18 years old and I am in the final stage of secondary school. I am not exaggerating when I say that this is the best lecture I have ever seen in my entire life. What very excellent information, experiences and explanation. Although I do not know much English, I activated the translation feature. Your teacher is wonderful and the patience is incredible. You should be grateful for having all these tools. What is exciting about This is all 10 ten years ago 😲 I wish I could study with you, Talama. I love biology very much But unfortunately he is not financially capable What is my fault? I was born from a poor family and a poor country like Iraq. I wish I had been born in a European country so that I could achieve my dreams because my passion never ends. Stay well and sincere thanks and appreciation to you❤❤

[@TonySoprano55]

Damn such good teaching quality at MiT people who go there are lucky

[@iknowtospeak]

can anyone alongwith me, take a moment to acknowledge the beauty in maam’s handwriting and presentation❤

[@fragrantbloom]

Great lecture! Thank you teacher 😊 Using the blackboard was really nice. Power points are getting boring. I could understand everything! Really helpful, thanks for posting.

[@allenculbertson8170]

I'm a really hugh fan of MIT OPENCOURSEWARE. I find it very informative, very useful, and the professor's explain it so it's easy to understand. God bless MIT OPENCOURSEWARE and thank you for sharing 🙏

[@jesserop3207]

Great content delivery! Succintly laid out the main points with very relevant examples.

[@zopa3631]

"DESPITE THE HYPE; DESPITE THE COVER OF TIME MAGAZINE;AND THE FRONT PAGE OF EVERY NEWSPAPER ACROSS THE WORLD ; STEM CELLS ARE NORMALLY FOUND IN OUR BODIES" Loved the statement......😎

My professors use PowerPoint and i haaaate it ! This so much better ..

[@Synflood-dot-txt]

agreed 100% can follow everything and take screen shots

[@notgeneralroblox]

Good lecture, its kind of funny how this is now counted as general knowledge and is teached at colleges when just 10 years ago this was Uni stuff

[@kevinboone2178]

Dr. Sive's a wonderful teaching biologist. To more effectively use time -- to answer student questions, for example -- I would allow students to access notes and screen images to their phones, tablets and/or laptops.

[@savaninagarkar7395]

Absolutely loved every single minute of the lecture!

Thank you, you have just made my Christmas revision that much easier. Many thanks

[@BraveFox100]

Teachers at MIT must be advised to write in the board. I don’t see this often in biology classes

[@미후루루집사]

Wow, it's a really nice video that's healing. Thank you so much for your wonderful performance

[@NehadHirmiz]

Excellent Lecture. Thank you very much :).

[@swadeshtaneja3512]

Very beautiful handwriting and so is the organization and explanation

[@joepup8348]

I like how the school known for technology, hence Massachusetts Institute of Technology, knows when too much technology is too much. So, they shun PowerPoint in favor of good 'ol chalkboards. Now THAT is smart.

[@chiyoeatyourtomatoes]

The rubber ducks are a nice touch

[@Robotbeauties7777]

This seams to be from quite solid days !

[@appybee]

Thank you, Professor!

[@santoshpatil2692]

Very nice explanation of topic and using all relevant examples. Improved my knowledge thanks a lot!

A VERY GOOD CLASS

[@funny11744]

Regarding the stem cells from URINE obtained after urination: HOW MANY TYPE OF STEM CELLS CAN WE FIND IN THAT URINE ? We can find only USCs ( urine stem cells ) or we can find also other stem cells ? . Is there any public protocol to separate if there are many types than USCs? Thank you.

[@sibusisonyoni1666]

Beautiful lecture thank you!

[@richardcortez6538]

Great professor great teacher 😀😀

[@md.shyamuddin5660]

[@jackpearce1728]

Would love to see a follow-up that addresses the Problems and carry's forward to today...some 3 years forward. As she says...the promise of the future that is in most cases being advanced outside of the US.

[@stemcelltreatment]

Excellent idea Jack. That is an important piece of the puzzle that doesn't get enough attention unfortunately.

[@dr.ashutoshchoudhuryveteri9143]

beautifully explained thank you ....

[@Wahrscheinlichkeit]

superb professor!

[@maxedout360]

I can't believe its available for free 😮

[@Mettabeshay]

is there a difference between differentiated and committed?

[@kmk2555]

yes, differentiated cells would be the earliest stage of a stem cell; embryonic

[@davelangford2439]

No they wouldn't. A differentiated cell is at the complete other end if the process. An embryonic stem cell is totally undifferentiated, hence why it's called a totipotent stem cell.

[@sarahk6926]

An embryonic stem cell is pluripotent not totipotent, as it can't make trophectoderm/placenta

[@jennazhang4927]

I love her course!

[@AsadUllah-lr2no]

Excellent lecture

[@perryreasch1209]

LOVE THIS VIDEO

[@KintaroCellsPowerInternational]

Interesting video. How do you feel about mesenchymal stem cells therapy?

[@TalkinNews]

excellent teacher

[@butterflyscience6043]

Tqsm mam nice explaination 🤩🥳✨🙏🙏

[@thenexus8532]

In what experiment were they artificially found. LCD chain conveyer please I got no rna cycle brain is leaking synius

[@theatticmonster1110]

I may have missed something here but she stated that there might be non compatibility issues with the embryonic stem cells and a none 'genetic' (wrong word I know!) match, which is understandable, but how did it work with the hairless mice? Any responses please keep as simple as possible I've just started researching this and am yet to get into full swing. Thanks!

[@AngelaWu1]

The hairless, or we call them nude mice, have been engineered so that they have an extremely defective immune system, almost no immune system at all. Therefore, they do not have any issues of rejection. Rejection of foreign materials from our bodies is based on the fact that our immune system can recognize self vs non-self (by way of antibodies and cell surface receptors - these protein molecules are like feelers that will touch all the things that enter your body, and check if they belong to you. They can signal other immune cells to mount an attack on any foreign matters, because it could be dangerous. This is why our immune system can eliminate bacteria and viral infections from our bodies most of the time). The immune system recognizes cells from another person as being foreign, because those cells will have a different genome, thus making proteins that are slightly different from our own. Therefore, if a person has an organ transplant, the recipient's immune system will try to attack the donor organ thinking it is foreign and bad. That's why transplant patients need to taken immunosuppressant drugs to keep their own immune system from destroying the donated organ - which then at the same time makes the transplant recipient more susceptible to infections and getting sick. Now you see, that nude mouse has no immune system, so there is no 'security team' to recognize foreign matter, so there is no issue of rejection. This ended up longer than I anticipated... hope it is helpful.

[@theatticmonster1110]

Oooo yes that makes sense, I didn't know about the nude mice being engineered to have a defective immune system, good to know for future ponderings and will also stop me asking silly questions. Thank you very much!

Can stem cells help adhd for 8 year od and a 15 years old

[@MariuszKulesza-i3c]

The s.c. can replace some damaged tissue. As I am aware people with ADHD have some problems with under-expression of dopaminergic neurons, so they need extra stimulation. Maybe, in the future will be possible to replace part or the whole nucleus accumbens, which is responsible for "feeling happy" and the reward system.

I like how she writes down whole sentences on the board. I guess MIT has really low expectations of their students.

Can someone answer my question: How many kinds of adult stem cells exist??

[@AliHanafiah]

Nice

[@bliss_XD]

[@ronturnbull2786]

Let's talk about one of the biggest advances in bio-technology ever ... but we'll use technology from 100 years ago to explain it. Why does she need to write all of this on a chalkboard? Why not a projector with slides ... or at least markers? Much easier than writing with chalk. She could cover so much more material in the allotted time if we weren't watching her write everything while she is facing the chalkboard. It should be more like a TEDtalk where she speaks to and engages the audience while the show behind her is secondary to the discussion and does not require her full attention.
