Lab grown meat is made by the controlled culture of animal cells. Scientists commonly grow cells in the lab, and this process is not too different. While the specifics behind how lab meat is grown in companies is proprietary, the basics behind it consists of keeping cells happy in a culture environment to promote their survival and continued growth.

Lab grown meat starts with animal cells, typically muscle or fat cells, or stem cells that are forced to differentiate into muscle cells. These cells are cultured using the appropriate growth medium that contains nutrients that promote its growth and survival. To aid in the growth of culture as it begins to expand, edible scaffolding is sometimes used. Finally, cells are allowed to divide and expand until ready to use, all the while being monitored consistently for harmful bacterial contamination.

Select the alternative with the correct use of a question tag related to the text.

A The cells are alive when they are manipulated, are they?

B The labs where they produce meat constantly check for bacterial contamination, can't they?

C The culture of animal cells is controlled, don't it?

D The scientists that make lab grown meat use stem cells, don't they?

E Lab grown meat does not come from slaughter, doesn't it?
