Differentiation protocols used to generate stem cell-derived islet cells yield heterogenous cell populations. We generated a human embryonic stem cell line that reports insulin- and glucagon-expressing cells in vitro and in vivo without altering their differentiation or function. We showed some insulin- and glucagon-expressing bihormonal cells are cell-autonomously fated to become α-like cells. This reporter cell line can be used to further study and improve stem cell-derived islet differentiation and transplantation.
