Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p>CD38 is a multifunctional membrane enzyme and the main mammalian ADP‐ribosyl cyclase, which catalyzes the synthesis and hydrolysis of cADPR, a potent endogenous Ca²⁺ mobilizing messenger. Here, we explored the role of CD38 in the neural differentiation of mouse embryonic stem cells (ESCs). We found that the expression of CD38 was decreased during the differentiation of mouse ESCs initiated by adherent monoculture. Perturbing the CD38/cADPR signaling by either CD38 knockdown or treatment of cADPR antagonists inhibited the neural commitment of mouse ESCs, whereas overexpression of CD38 promoted it. Moreover, CD38 knockdown dampened reactive oxygen species (ROS) production during neural differentiation of ESCs by inhibiting NADPH oxidase activity, while CD38 overexpression enhanced it. Similarly, application of hydrogen peroxide mitigated the inhibitory effects of CD38 knockdown on neural differentiation of ESCs. Taken together, our data indicate that the CD38 signaling pathway is required for neural differentiation of mouse ESCs by modulating ROS production.
