A team of bioengineers have taken cells from a rat's heart and used them to create a 'Franken-jelly'.
To create the creatures, scientists arranged the rat's heart cells on a piece of rubbery silicon and applied an electrical charge. The jellyfish look and move like the real thing, each pumping water in and out of its body as it swims around. It is hoped that the research will help to advance the field of artificial hearts and other organs.
Bioengineers Kevin Kit Parker and John Dabiri aimed to 'copy nature' when they set out to build the jellyfish and the motto seems to have worked. "Some engineers build things out of concrete, copper and steel - we build things out of cells," said Parker.
The duo and their colleagues stenciled out the ideal jellyfish shape on silicon, a material that would be sturdy but flexible, much like the jellyfish itself. They then coached rat muscle cells to grow in parallel bands on the silicon and encased the cells with a stretchy material called elastomer.
Not "life", merely a construct using heart cells which beat rhythmically. The cells will likely not live long and the "jellyfish" will become a slice of floating silicone once more. Now when scientists can build one with artificial nematocysts, then I'll really be impressed.
I hope all the rats that had to die for this experiment didn't die in vain.... Something good better come out of this. Sounds like they are just playing around to me.
Just what we needed ! Oooowww ahhhhhh ,our tax dollars at work ,with so many practical uses ! I'm so happy about this,I am plotzing ! Heart muscles contracting out of the body ! This is certainly a new novel concept ! May I repeat ,OOOOOOWWWWW AHHHHHHH
this isnt a clone, its a peice of ruber coated with living cells that swim and look like a jellyfish. i would estimate they are electricuting the water wen they want the thing to pump and swim. its not alive, just coated with hearth cells
I hope all the rats that had to die for this experiment didn't die in vain.... Something good better come out of this. Sounds like they are just playing around to me. I agree so lets hope there is some practical use for what they are doing.
