Resumen

Engineered bacterial therapeutics are emerging as promising candidates for the treatment of solid cancers. However, despite effectively reducing tumour burden in different pre-clinical models, these “smart bugs” are yet to convincingly translate this efficacy to cancer treatment in humans. Here, we highlight key features of in vitro co-culture methods and how they can be used to investigate bacterial behaviour and guide the rational engineering of more effective anti-cancer bacterial therapeutics.
