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.

"soak it in an ingredient commonly found in shampoos" What the fuck am I putting in my hair?!

Displayed in the Saint-Étienne church in France is the figure of René de Chalon, Prince of Orange. The prince died at the young age of 25 during the siege of Saint-Dizier in 1544.
Rather then memorialize him in the standard hero form, his wife requested (or René himself requested, or possibly both) that he be shown as “not a standard figure but a life-size skeleton with strips of dried skin flapping over a hollow carcass, whose right hand clutches at the empty rib cage while the left hand holds high his heart in a grand gesture.” (Source)
10 Slides is not enough. So many other things I wanted to talk about, like Sex-Repulsed and Sex-Positive Aces and everything in between.
But in the end, I really wanted to give Aromanticism some visibility, and Demisexuals and Grey-As I thought rounded the thing out nicely by helping explain to people searching for their identity that asexuality need not be black and white.
Yeah, I had the same problem. I definitely cried my eyes out and then stayed in my room all curled up for the rest of the day after I finished the first season. So many of the things they talk about in the show are incredibly relevant and close to home and it’s just such a powerful show.
i literally never get tired of this post
