October 4, 2018 from the OU and New York Times:

The OU is working with companies that are producing "clean meat"
"Clean meat, also known by names like cell-based agriculture, begins with cells taken from an animal, often stem cells that are primed to grow. Once these cells are isolated, they are put into a solution that mimics blood and encourages the cells to replicate."
The OU is concerned about where the cells come from. The cells cannot be scraped off a live animal. If the cells come from animal saliva or hair these are not considered to be meat so could be used to produce "clean meat". Another concern is and the constituents in the growth media. The New York Times article says that " just as kosher cows can eat non-kosher insects, he is working from the assumption that the growth solution will not have to be certified as kosher as long as it is cleaned from the surface of the final cells."
