This is muscle tissue, grown in a vat. Could we get to a point where vivisection becomes a thing of the past? We might one day look at the scientific testing on animals as primitive as when people were drilling holes into frontal lobes to remedy mental disabilities. If we can grow muscle tissue in a vat, now, then there might be a future merger between this and the nanotechnologies that are in development that might create a way to physicially wire biological nerves with electronic circuits.
