"No, man, it would just scar over." "Duh, you would have to, like, steal one." "The body doesn't know how to regrow limbs and stuff like that after you're out of your mom's fetus." "'Fetus'?" "I mean uterus. Shut up. You need stem cells." "Oh, so we COULD regrow one now, couldn't we?"I love you guys, and technically you are correct, but let's look over why you are correct.
"It would just scar over."
If you were to cut off your nipple, and just let it alone, the area would simply scar over. Nipples, in both men and women, are structurally distinct from the rest of your skin; composed of not just skin, but glandular and fatty tissue as well. If you were to cut it off, you'd only grow scar tissue. Nipple removal is actually a practiced type of body modification in certain communities, though it does carry a number of inherent risks. I wouldn't recommend it.
"Duh, you would have to, like, steal one."
Not totally true, but theoretically possible. There are methods, for example, that spare the nipple and allow women to retain them after a mastectomy. It may also be possible to grow pigmented skin cells that can later be transfer to simulate a nipple after you've lost one.
"The body doesn't know how to regrow limbs and shit like that after you're out of your mom's fetus."
This one is REALLY complicated, and could lead to an entire series on fetal development, but today, we're just going to focus on the body part in question. Until you are 6 weeks old, all humans begin development looking the same, it isn't until that point in time that any male-specific characteristics begin to emerge. So, why do men have nipples? Because women do. After 6 weeks, male fetuses (usually) begin producing enough testosterone to halt breast development. HOWEVER, if you were to cut off a fetus' nipple (you horrible horrible person, you) it still wouldn't grow back. Just as a fetus' ear wouldn't grow back (seriously, what is WRONG with you?), because...
"You need stem cells."
There are 5 types of stem cells you all need to know about.
- Totipotent cells can divide to become ANY cell of an organism. Potential-humans are made of totipotent cells until they have become a 16-cell ball. After which the bundle becomes a morula which divides itself into differentiated cells.
- Pluripotent cells can turn into all three of three different layers of cells which eventually turn into a fetus. I.e. They can become the endoderm (interior stomach lining, gastrointestinal tract, the lungs), mesoderm (muscle, bone, blood, urogenital), or ectoderm (epidermal tissues and nervous system), but they can't do jack to help you live in the womb.
- Multipotent cells can divide indefinitely and can become a number of different cells of the same "type". For example, a blood stem cell can become a red blood cell, or a white blood cell, but it can't become a brain cell. Although, there may be ways to mess with this process.
- Olgopotent cells can only divide a couple times, but they still have the potential to turn into different things if you push them. (e.g. Bone marrow stromal cells can turn into bone marrow, cartilage or fat cells.)
- Unipotent cells can only turn into one thing. Livers, for example, can regrow themselves because liver cells are unipotent. Liver cells can only be liver cells.
What's so great about stem cells? They're toti-and-pluri-potent. With the proper techniques and growing environments, you can goad them into becoming what you want them to be, allowing people the chance to grow replacement-bits using their own cells. Ideally, this would mean you could regrow the individual bits of your missing nipple, and put them together to build a new one.
But you know what?
That would be really freaking complicated.

It would be easier to regrow a heart, or an ear. You know, something that is mostly one thing, rather than a structure built of different things. You have to BUILD a nipple.
Sheesh dude. Just don't cut your nipple off. Ok?
This can all be solved by keeping your nipple.
ReplyDeleteWhat about breast cancer? :/
DeleteBreast cancer doesn't make nipples go away!?!?! Mastectomies do. Wtf...the author of this article even says at one point, "spare the nipple and allow women to retain them after a mastectomy." So, yeah, pay attention.
DeleteHey Vencent I'm happy that I cut my nipples because if I kept them they would of fallen I did what had to be done

DeleteI heard a story back in high school of a fellow student who rode dirt-bikes. He made the genius decision to ride on some dirt piles without a shirt, however he wore a helmet. Smart.
ReplyDeleteI remember that he hit a hill, flew into the air and became separated from his bike. His chest rubbed against the ground like a cheese grater, and although I never knew or met the guy, I had heard rumors his stomach/chest was so messed up, he never grew any body hair nor did he have nipples again.
Whether or not that was true, it lined up with things I had heard about discussions such as yours above, so I believed it... but who knows if it's actually true.
My friend said that he knew a guy who's nipple grew back. yeah.
ReplyDeleteWell I have a nut job friend who removed his and they did not. They look like ruffled scar tissue and one hurts all the time after 7 months.
DeleteI enjoyed reading this.
ReplyDeleteHaha this was great
DeleteI was just curious because I was watching Daily Lives of High School Boys...
