I know there have been questions on whether lab meat would be Kosher or not, halavi or besari...
I see another potential debate. According to http://culturedbeef.net/what-is-it/, "Cultured Beef is created by painlessly harvesting muscle cells from a living cow."
The seven laws include "The prohibition of eating flesh taken from an animal while it is still alive."
The obvious question is then whether "harvesting muscle cells from a living" animal is equivalent to "flesh taken from an animal while it is still alive" ?
