While searching for a kidney donor, Karen Keegan stumbled upon a mystery. After undergoing genetic testing, it turned out that some of her cells had a completely different set of genes from the others. And this second set of genes belonged to her twin sister- who had never been born. How did this happen? Kayla Mandel Sheets explores the condition known as chimerism.

That story of a mother's liver growing back from her baby's stem cells is the most wholesome thing I've every seen.
Returning the gift of life.
i know. that story fascinated me too. I believe in supernatural heals and miracles because it is the undiscovered nature itself.
@@nanaouzumaki6044 Believing in the supernatural is just silly, as there is zero evidence for it.
Is "wholesome" a rude word* or nice one?
@@aleksitjvladica. a very nice word
@@aleksitjvladica. I don't think I've ever seen "wholesome" rudely so yes, it is in fact a nice word. It's similar in meaning to what we would call "heartwarming" and (at least how I have seen and used it) is used to somehow convey that a situation gives a feeling of "emotional fullness" or something similar.
At least that's how most of the stuff I have and have seen called "wholesome" made me feel.
"So, who's your mom?"
*"My mom was never born."*
Yeah thats...weird to here.
"When my mother was pregnant with me, they did an ultrasound and found she was having twins. When they did another ultrasound a few weeks later, they discovered that I had RESORBED the other fetus.

@@Kenny2100vn there's an interesting experiment in patients whose right and left brain connections are severed.
it is found that the right brain can act independently from the left, and at times patients describe their left sides disagreeing with their right. [like throwing an object out of their right side's hand]
basically we are actually two, but the right brain can't express itself since it can't control speech

I had a fraternal twin who sadly passed away in the womb. I always knew I have absorbed some of them as a fetus because I have an extra tooth, but I didn't know that it could be this severe, I could have whole organs with their DNA.. crazy
Can music save your mortal soul th-cam.com/video/-uexjy4sWu4/w-d-xo.html. Great watch!
My little brother, he absorbed his twin and gained a chromosome and lost chromosomes in some other things. It caused his organs to not fully develop. He was missing a lot of the vital organs. He’s organs were also flipped. He didn’t make it because he was missing those vital organs. But it was astonishing how much time we had with him. He also had extra fingers and toes. My mom got little plasters made of his little arms and legs and he had like an extra thumb and pinky toe 😆

Mind-blowing. Can you imagine how many times in history this has happened without us knowing? How many family trees are in fact inaccurate?
For sure. It's crossed my mind because I do genealogy.
To be fair, the kids still share the same set of grandparents from the parent who have chimerism.
Imagine having 2 kids without being born.
You can’t imagine it coz you wouldn’t have been born to know about it 😉

You've seen yourself somewhere you don't know when or where until it snaps and it's gone.

Light particles follow a rhythm/pattern until observed too closely.

With that logic. If u don't pay too much attention you can set of neurons in a way that seems like a premonition. You are here and then, but are u now? Or there.
How would you determine which genome is actually yours? If the separate genomes can be spread throughout the body in different places which would you say is the twin?
I was wondering the same thing, since wouldn’t there be an even amount of each?
@@ClumsyCloud i think the video said cell levels can differ from organ to organ. some organs may only have 1 type of genome, but another organ can have a mixture. maybe they can test and identify which genome is most common and class that as "your" genome in these cases?
I say two genomes, but still one person. They can’t be separated without killing the person.
Thats so cool.
Imagine your liver is failing and your long born child is like: "I will never let you die, mother" and heals you all alone.
“The genes that make us who we are” sounds like a Levi’s commercial.

@@ornevaeh9375 bruh
1:33 show this to that loathsome person in your life who calls unborn children "parasites." A parasite doesn't rejuvenate its host's failing organs.
I hate when people do that
By definition a fetus IS parasitic in nature. It can't survive outside of the host, it needs the host nutrients and it will die when the host dies. Simple as that. Facts over feelings ;).
A clump of cells will never be as important as the person who can carry those cells to term.
I love the sound of this video! The background music and the sound effects! It's so relaxing! And with the comination of the video it was spectacular! Please do more videos like that!
Injecting your own baby’s stem cell to regenerate organ sounds like a technology with huge potentials .
😳😳😳 im excited fr that to actually happen..but id probably be dead b that time
@@exp-io853 well it exist according to my science teacher, and can be obtained by the umbilical cord
@@yagomizuma2275 biology has so much in it..its crazy than i thought 😭
Seems like its mostly effective during pregnancy. Normally when random cells show up in your body, your immune system destroys them. The immune system of pregnant women is compromised specifically so that their immune system doesn't destroy the fetal cells growing in them. Once in post-partum though, the immune system gets back to normal, and destroys any foreign cells left behind *usually*. The instances of them surviving are rare, and the liver is a bit of a special organ in that it naturally can regenerate anyways. It's certainly promising, but there's alot to consider risk wise. What if when you go off the immunesuppressants, some number of peoples bodies recognize the foreign cells and destroy their shiny new organ
@@left4twenty I'm not an expert but can we modify something in our body to prevent them from destroying the stem cells?
By the title alone I think a new fear is unlocked 😅
Gaining a brand new fear is when you know found a great science video

Well, yes. As TED ED Watcher, now I am confused.
My wife and child to be born, during the first months, had another little heart beat and another little "baby room?" I dunno the medical term, one bigger with an obvious heart beat detected, the smaller one has vague heartbeat. The next 2 weeks we check, there is only one heart beat and one "baby room".
Is my baby to born going to be like this too?
@@salamanderred8148 oh well. Now at least you know what might have happened. Also I hope everything goes smoothly and as easily as possible for you and for them. And lot of happiness in the future
This was sooo beautifully made !!!!! . The animations and the narration are just too good !
Makes me wonder if people I know who look very different from their parents have a parent with chimerism. Fascinating!
The story of the mother's liver regenarating really moved me since I lost my mom to liver failure due to cancer ,wish that knowledge could be used to help people

I always wondered why I am slightly dual toned, like almost my left half is just so subtly a different shade of skin. I'm also slightly asymmetrical, and recently I was wondering about whether I'd absorbed a twin during my development. In fact, I asked my mother "Was I a twin during the first terms of the pregnancy?" And considering she didn't know anything about a twin, I might need to do some investigation! :D
So are you twin?

Very simply put. Thanks
I’ve heard of fetal cells regenerating maternal tissue before. It would be such a useful treatment for so many degenerative diseases!
Sadly, toti-/pluri-/oligopotent cells will much more frequently cause tumorous growths rather than target and regenerate damaged tissue as we currently do not have a sufficiently in depth grasp of all the signaling and differentiation going on as well as just the general biology of “stem cells”
Wow, having an unborn person's child must be tremendous. Nature always surprises us.
My husband has three different colors of hair... Mostly brown hair, but also some blonde and red. Blink, blink.

Great. Just 2 days ago I was watching a documentary about hand transplants which got me wondering, what happens to a person's DNA when they get an organ from another person.

1:01 is my favorite part. The split of the person and the music is just an amazing pair.
this video is so educational aesthetic and calming
This is absolutely fascinating
I was a little spooked when I saw this because my twin wasn't born. I used to tell everyone when I was a kid but it was dismissed as a joke and I only remembered it recently. My therapist said it was actually common and that sometimes the twin who was born mourns the absence of the other, which is my case. I thought this video was going to talk about that and felt a little scared but now I see it mentioned this in a more scientific take. It was interesting to know. I hope I have something of my sibling to carry along with me, even if it's a single cell.
That is so cool and amazing. I hope Ms. Keegan got the help she needed, though. Astounding animation as always; really great stuff.
