Yeah, exactly that. One mess up at a time
This new technology is being called biofabrication and its ultimate aim is the 3-D printing of entire human organs. Traditional 3-D printing is a machine process in which an ultra-fine nozzle extrudes particles - usually of plastic or metal - and micro-layer by micro-layer creates a 3-D object. Biofabrication adopts this process but uses living cells rather than plastic or metal as its building blocks.
Biofabrication scientists have already 3-D-printed human blood vessels using stem cells first cultured in a lab to grow into blood vessel cells and loaded them into a 3-D bioprinter. Because the stem cells are taken from the patient who will receive the blood vessels, it’s hoped that rejection of the new vessels will be unlikely. Now scientists plan to put the blood vessels through human clinical trials to prove that it is functional and able to grow, paving the way to a future in which damaged blood vessels can be treated with 3-D-printed replacements.

People are basically good—when provided a tool that helps them do good in the world, they prove it.
Jelly is a new company and product named after the jellyfish. We are inspired by this particular animal because neurologically, its brain is more “we” than “me.” Also, for the past 700 million…
