a decellularized “ghost” heart
aaaaaaaay extracellular matrix
How cool is it that when you take all the cells out of an organ it still looks like an organ?
I remember when I was in high school and still very confused about how tissues worked, because all anyone taught me was that we’re made up of piles of cells hung on bones. But that’s not how it is! Cells build themselves little hammocks of polymer and densely branched glycoproteins; we’re like onions, layers of membrane over tough rubbery collagen, huge protein scaffolds cradling slippery organs.
Bodies are not made of cells — bodies are made by cells.
Shit, major kudos to OP for making me aware of this, and isozyme for explaining — I had no idea the extracellular matrix was so substantial.
This is doubly cool because a heart that has been “washed” of cells like this is an incredible leap forward for donor organs. It’s much harder to reject something that doesn’t have non-host cells. As I understand it, they would use something like this with stem cells from the recipient to basically custom-make a new heart for themselves.
Starve the ego, feed the soul.
This is so perfect, for the time you look at this image, you don’t know if it’s a boy and girl, a girl and a girl, a boy and a boy, a black man and a white girl, a white man and an asian girl, you know nothing. Just the simplicity of the connection and the beauty of two human beings sharing love and that is all that should ever matter.
Actually, Due to the slight prognathism of the maxilla, the smaller more rounded cranial vault. The sharper and less defined lower mandible, and less protruding supraobital ridges, the conclusion can be reached that the individual on the left is female, and of African American decent. However the individual on the right shows a larger more oblong cranium, heaver more protruding supraobital ridges, a flatter maxilla with less prognathism. Also the lower mandible of this individual is heaver, more defined and square. From the presence of these features the conclusion can be reached that the individual on the right is male of Caucasian decent. Also due to the advanced (but not complete) obliteration of the cranial sutures, and the presence of a third molar in each individuals, it can also be said that both of these individuals are between the ages of 25 and 40.
ok there sherlock
My girlfriend says i do this to everything. She’s right.
