The heart makers

The heart makers

How do you make a working human heart? Scientists can turn stem cells into beating heart cells, but getting them to organize into a 3D heart requires a scaffold.

At the Massachusetts General Hospital in Boston, Harald Ott and his team are reusing the scaffold that nature provides. They’re stripping away all the living cells from dead hearts, before filling in the leftover matrix with healthy new cells.

In this video, Brendan Maher finds out how the technique could be used to develop parts of the heart, like the aortic root and valve, for transplant.

    I wonder if this type of thing would work for bottom surgery for female to male because they haven’t yet figured out how to make erectile tissue. this might be the answer.

    This only last for hours after transplanting in animals. Maybe artificial heart can be better

    Creepy

    Billions and billions of government funding went to vaccines. These doctors work at the local brew pub on weekends to make ends meet.

    A whole laboratory to make heart . And we were created in our mama’s tummy.
    Btw that beats 5:32 is really cool❤️

  8. István Székely on March 25, 2021 at 10:54 pm

    And What happen if they use the right or the left lung like a blood
    pump. After some artifical modification it can transport blood instead
    of the heart, without external powersourch.

    Now we can! That’s great

    Does the decellularization process destroy brain cells and their synapses?

    7 years later and not a word !

  16. Francis Santiago on March 25, 2021 at 11:03 pm

    I want to see scientists will make living human clone ^^

  17. OMA GAWD on March 25, 2021 at 11:07 pm

    At first i tought it was an albino heart

  18. Dabunny Rabbit on March 25, 2021 at 11:07 pm

    I wonder if this could be done with a foreskin.

  19. Testing Testing on March 25, 2021 at 11:13 pm

    O people, an example is presented, so listen to it. Indeed, those you invoke besides Allah will never create [as much as] a fly, even if they gathered together for that purpose. And if the fly should steal away from them a [tiny] thing, they could not recover it from him. Weak are the pursuer and pursued.

    Now ive found this rabbit hole, i cant wait for meat apple

  21. Sai Haku on March 25, 2021 at 11:14 pm

    I’m trying to find Labor video that can creating organs…but most of cells creations video gone 7years+ ago. i believe they could creat a labor living thing from now day technology..if you guys can creat new working organs the entire sick people could be help. i know it would be chaos but why…all of us are just bionical android machines after all…

  22. ErikDagdagan on March 25, 2021 at 11:17 pm

    This was 7 years ago, Imagine the progress they’ve made till now.

  25. Isse Ismail on March 25, 2021 at 11:19 pm

    Why is it yellow

  26. U•K THE COMMENTER on March 25, 2021 at 11:19 pm

    *Who got this Reccomended after 7 Years*

  27. Isaac Westawski on March 25, 2021 at 11:20 pm

    how do they make the hearts nervous system though?

  28. rone miralles on March 25, 2021 at 11:22 pm

    no one youtube in 4050:
    How to make "heart" Diy

  29. Barak Osman on March 25, 2021 at 11:22 pm

    This is wrong only god can creat things such ass life

  30. Esphy on March 25, 2021 at 11:24 pm

    Why am I here?

  31. Arthur Baca on March 25, 2021 at 11:24 pm

    This is amazing these well save so many lifes #fact

  32. Dabunny Rabbit on March 25, 2021 at 11:25 pm

    the heart is definitely more important, but I’m hoping this will also include the foreskin.

  33. God's Community on March 25, 2021 at 11:25 pm

    Peaceful blessings.

    what if the replacement part is rejected and it causes heat failure

  35. Thanh Nguyen on March 25, 2021 at 11:29 pm

    So basically you can construct life using science, oh no.

    U realised hé have a hearth

  39. Harvey on March 25, 2021 at 11:31 pm

    It’s bad when an informative video like this calls a heart an organ mate it’s a muscle

  40. Adam on March 25, 2021 at 11:31 pm

    “Certified refurbished”

  41. Alfred Gonzalez on March 25, 2021 at 11:33 pm

    can you used a bioprinter

  42. mike avery on March 25, 2021 at 11:34 pm

    Can’t you just scan a heart and replicate the scaffolding with a 3D printer using biodegradable material that degrades after 5 or 6 weeks and use stem cells along with heart cells to grow a heart in the biodegradable scaffolding it seems like you guys are doing it the hard way when all you need is a little bit of crisper and a little bit of stem cells from a placenta.

  43. RS Redbaron on March 25, 2021 at 11:35 pm

    This is all?

  44. paul delekto on March 25, 2021 at 11:38 pm

    Wow I do actually want to know how they did this even when they took the cells out its actually pretty interesting.

  45. masaab salh on March 25, 2021 at 11:39 pm

    The future of transplantation recognizes the body for an organ so that it is not oxidized

  47. Kent Lawton on March 25, 2021 at 11:43 pm

  48. ButterSnaps Wright on March 25, 2021 at 11:44 pm
