Enteroendocrine cells (EECs) control a wide range of physiological processes linked to metabolism(1). We show that EEC hormones are differentially expressed between crypts (for example, Glp1) and villi (for example, secretin). As demonstrated by single-cell mRNA sequencing using murine Lgr5(+) cell-derived organoids, BMP4 signals alter the hormone expression profiles of individual EECs to resemble those found in the villus. Accordingly, BMP4 induces hormone switching of EECs migrating up the crypt-villus axis in vivo. Our findings imply that EEC lineages in the small intestine exhibit a more flexible hormone repertoire than previously proposed. We also describe a protocol to generate human EECs in organoids and demonstrate a similar regulation of hormone expression by BMP signalling. These findings establish alternative strategies to target EECs with therapeutically relevant hormone production through BMP modulation.
