36 results about "Cultured meat" patented technology

Cultured meat is meat produced by in vitro cultivation of animal cells, instead of from slaughtered animals. It is a form of cellular agriculture. Cultured meat is produced using many of the same tissue engineering techniques traditionally used in regenerative medicine. The concept of cultured meat was popularized by Jason Matheny in the early 2000s after co-authoring a seminal paper on cultured meat production and creating New Harvest, the world's first non-profit organization dedicated to supporting in vitro meat research.
