In non-senescent Hydra, continuously high activity of transcription factor FOXO contributes to continuous stem cell proliferation. Here, we describe how genetic manipulation of Hydra polyps using embryo-microinjection allows uncovering the role of FOXO in coordinating both stem cell proliferation and antimicrobial peptide0073, effector molecules of the innate immune system, and regulators of the microbiome.
