Generation and characterization of POMC-tdTomato reporter human pluripotent stem cell lines.

ABSTRACT: Proopiomelanocortin (POMC) is a precursor polypeptide that undergoes extensive, tissue-specific post-translational processing. It is expressed in several tissues, including pituitary gland, hypothalamus, brain stem, and skin. The hypothalamic POMC neurons in the arcuate nucleus are major neuronal populations involved in the regulation of body weight. In these neurons, POMC is processed into several peptides, among them the anorexigenic alpha-melanocyte stimulating hormone. Thus, the POMC neurons in the ARC have been named "satiety" neurons and are highly desirable drug targets. Here, we performed CRISPR/Cas9-mediated insertion of tdTomato reporter at the endogenous POMC locus, enabling direct visualization of POMC expression through tdTomato fluorescence in human pluripotent stem cell (hPS
