Lab-grown meat: the science of turning cells into steaks and nuggets en (nature.com)

Companies making cultured meat are attracting billions of dollars of investment. Here are their biggest challenges.

Summary:

• Lab-grown meat could be available to consumers by 2023
• Don't expect the first available lab-grown meat to be affordable
• Growing meat from cells is difficult. Researchers are trying to 1) find the optimal starter cells, or 2) use immortal cells (think HeLa) which should be safe
• Conventional feed/culture for research labs come from cows, so ppl are developing plant-based alternatives. Unfortunately every company is using their own proprietary solution
• Health issues pertinent to meat will still be present, although lab-grown will be much better to animal welfare
• Lab-grown meat will take up far less land, but require a lot more energy per kilo compared to even beef
