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.
This is the coolest fucking thing ever. Science, man. Fucking science. Shit completely blows me away.
I get complaints from customers on a daily basis.
I’m probably going to be fired soon, even though I’ve earned, yet another, raise already.
I am the nicest person, everyone says so. I’m just not good with strangers. Who are already “in a mood” usually, and find it rude that I don’t show them love and affection as they come through my line.
People still go to Walmart even though the people that work there hate their lives.
Why do they have to bitch about me just because I work with a smile and don’t ask about their day? There are only so many questions you can ask about a person’s day.
I wish I was good at anything.
I want to find another job.
I had a horrible nightmare where my fiance died.
It ended with me crying and puking, with blood.
So I died too. And there was really scary dark water next to me.
So, if I had any doubts about marrying my fiance, they would all be gone now - knowing I would die without him.
Everyone I know is already married and with kids.
So thinking about my own wedding just makes me want to puke.
I wish I had money and could pay someone to make a really pretty wedding with all super neat stuff. But I’m thinking more of a backyard wedding. I’m not a girly enough person to worry about all that junk. But it would be nice if it was cute. Don’t know if we’ll actually have a honeymoon. I had a magazine around here about local places, but he moved it and now it’s gone, so…
It’s awkward thinking about how I have no one to invite except my parents. And no best woman…bridesmaid (forgot the word)
I’d rather just wear my annoying ring that spins around and hits everything throughout my day And forget about the whole ceremony thing.
and I have no one to tell except my parents…
And I already chickened out once on telling them lol
I just want to enjoy being happy about it before anyone even thinks about doubting my choice.
Pipos Doll Animation (by DollPaCa)
That was sadder than the opening bit in Pixar’s UP.
Everything about this was perfect. The animation could not be any better; the lack of actual words yet it still portrays rich emotion. In the beginning, it shows how a family can continue on. But as it goes, it shows that tragedy can still happen. Life is life.
There are tears rolling down my face, and the only thing I would criticize is that felt no closure in the end. When the screen went black it felt like my heart stopped because I didn’t want it to end.
so horribly sad and moving :’(
A local brony is outraged when he purchases an activity book for little girls and discovers that it was not made for grown men

My boyfriend gets upset when I’m tired of seeing his parents every week. On our only days off together.
why don’t we go see my parents every day we have off? I don’t even get to see my mom because I’m so busy seeing his every other day.
