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.

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 😆

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

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. And KZfaq recommended me the answer today.

I really need to do further studies on this. 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

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”

My husband has three different colors of hair... Mostly brown hair, but also some blonde and red. Blink, blink. When I was pregnant with my son, I could have sworn there was a twin... Now that I know that so many pregnancies start of as twins, maybe I was right. I had no idea!

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.

@Denuhm 2 жыл бұрын

@@chelseazaydaraensehon1198 It's extremely rare to my understanding that a twin like my mother's affects the reproductive system specifically, we only knew what was going on because of my mother's underlying health issues and the 'twin' being found and removed and then later when our family genetic tests came back a little wonky and talking to a geneticist to confirm. You will only have this outcome IF your mother had a twin that died in utero at a later stage and it became incoprporated with her body and reproductive system to some degree.
