The manga has inspired several spinoff series such as Hataraku Saikin (Bacteria at Work), Hatarakanai Saibō (Cells That Don’t Work), Cells at Work! Code Black (Hataraku Saibō Black), Hataraku Saibō Friend, and Hataraku Kesshōban-chan (Platelets at Work). The first television anime adaptation of the manga premiered in July 2018.
The first 2020 issue of Kodansha’s Morning magazine revealed on Thursday that Yasuhiro Fukuda’s Hataraku Saibō Baby (Cells at Work! Baby) spinoff manga of Akane Shimizu’s Cells at Work! manga will take a two-month hiatus and return in the magazine around February 2020.
Shimizu launched the original Cells at Work! manga in the March 2015 issue of Kodansha’s Monthly Shonen Sirius, and Kodansha shipped the fifth compiled volume in Japan in August 2017.
Fukuda’s spinoff manga centers on cells inside the body of a baby 40 weeks since conception and nearing delivery, with all the cells knowing nothing.
