Today's show:

*Most lab-grown meat companies have already gone under. It's expensive to produce, and there's little demand from real-world consumers. But Tokyo's IntegriCulture is still standing after selling their proprietary serum to cosmetics companies.

On Episode 3 of TWiST from Tokyo, Jason sits down with Dr. Yuki Hanyu, an Oxford-trained chemist who started a DIY meat movement out of a comic convention and turned it into Japan's first cell-cultured protein company.

PLUS why the cultivated meat market stalled out, why producing a "slurry of cells" is more efficient than jumping right to muscle tissue, the regulatory framework in Japan vs. the US, and… is it fair to call this "meat"? Or is it something else entirely?
