I’ve seen this photograph very frequently on tumblr and Facebook, always with the simple caption, “Ghost Heart”. What exactly is a ghost heart?

More than 3,200 people are on the waiting list for a heart transplant in the United States. Some won’t survive the wait. Last year, 340 died before a new heart was found.

The solution: Take a pig heart, soak it in an ingredient commonly found in shampoo and wash away the cells until you’re left with a protein scaffold that is to a heart what two-by-four framing is to a house.

Then inject that ghost heart, as it’s called, with hundreds of millions of blood or bone-marrow stem cells from a person who needs a heart transplant, place it in a bioreactor - a box with artificial lungs and tubes that pump oxygen and blood into it - and wait as the ghost heart begins to mature into a new, beating human heart.

Doris Taylor, director of regenerative medicine research at the Texas Heart Institute at St. Luke’s Episcopal Hospital in Houston, has been working on this— first using rat hearts, then pig hearts and human hearts - for years.

The process is called decellularization and it is a tissue engineering technique designed to strip out the cells from a donor organ, leaving nothing but connective tissue that used to hold the cells in place. 

This scaffold of connective tissue - called a “ghost organ” for its pale and almost translucent appearance - can then be reseeded with a patient’s own cells, with the goal of regenerating an organ that can be transplanted into the patient without fear of tissue rejection.

This ghost heart is ready to be injected with a transplant recipient’s stem cells so a new heart - one that won’t be rejected - can be grown.

Excuse me but we can’t just kill pigs to save human lives. That is wrong.

Found the vegan

Ahem.
BREASTS ARE NOT SEXUAL ORGANS YOU INCONSIDERATE DICK!
Breasts are mammary organs, meaning their true and primary purpose is to nurse babies.
I’ll repeat that for the slow people in the class, you warthog-faced buffoon.
Breasts are mammary sacks. They are meant to feed babies, just like a cow’s udder. They aren’t sexual organs. They aren’t classified as such in biology texts (certainly none of the ones I checked out to answer this post)
Men have breasts, you pile of refuse. Their breasts are smaller than women’s, but they possess the same mammary glands and, properly stimulated, can produce milk. Men can get breast cancer. They can develop larger breasts due to excessive hormones. Their breasts are exactly like a women’s breast, except that since their testicles produce testosterone in high degree, they don’t have enough female hormones in their bodies to start lactating.
So, you pile of putrescence, you’re probably thinking, “If breasts aren’t sex organs then how come guys get horny looking at them and women get turned on by playing worth them, huh?”
The answers to both are so terribly simple that you might just be able to follow them if you pay attention, pig.
Men are enticed by breasts because they’re not allowed to see them. Women are sensitive because stimulation triggers two responses - bonding hormones and lactation.
In case you’re too simple to get this, I’ll break it down further for you. In cultures where breasts are viewed daily, they don’t do much to get a guy hot and bothered. There are hundreds of paintings from the renaissance period and earlier depicting women nursing babies, especially images of the Blessed Virgin nursing Christ, and none of these have ever been considered provocative, because that’s what boobs are for. Meanwhile, in cultures where everyone from baby sister to great-great grandma walk around topless because the weather will kill them otherwise, dudes don’t get raging erections every time they see a breast. They don’t find boobs enticing the way men do in America, where boobs are considered shameful and need to be hidden.
As for women getting aroused by their boobs being played with, you brainless donkey, a woman’s body responds to get nipples bring touched by flooding her body with bonding hormones that help her attach to get babies - you know, the people her breasts are actually supposed to be used by - and hormones that get her glands making milk. Also, please note that many women with large breasts don’t feel any stimulation when fondled, meaning they aren’t sensitive enough to get off on having their boobs played with.
Do me a favor and GET THE FUCK OVER YOURSELF YOU PURITANICAL ASS! My breasts are NOT SEXUAL ORGANS. They are lactation organs designed for my use and my baby’s use. Not for any man’s use or pleasure.
You inconsiderate space herpe.

This just in people cant tell the difference between genitalia and secondary sex traits

THANK YOU GENIUS SIDE OF TUMBLR.

I would also like to point out that men are also capable of getting aroused by having their nipples played with, so by that logic men should be covering up their nipples in public.
