Adverse effects of gestational Δ9-tetrahydrocannabinol exposure on the embryonic germline transcriptome and metabolome


ABSTRACT: An increasing number of women report cannabis use during their pregnancy, with little knowledge on the repercussions of such an exposure onto early embryonic processes. In particular, exposure to the most abundant phytocannabinoid, Δ9-tetrahydrocannabinol (Δ9-THC), could alter the development of embryonic germ cells, with potential consequences across generations. Here, we extensively characterized the impact of gestational exposure to Δ9-THC onto the developmental trajectory of an in vitro model for primordial germ cells. Our data reveals that Δ9-THC exposure increases glycolytic rates in embryonic stem cells, with consequences on their proliferation. We further show that, in the absence of continuous exposure, Δ9-THC has long-lasting adverse consequences on the metabolome and transcriptome of embryonic germ cells. These results constitute the first characterization of the impact of gestational Δ9-THC exposure onto the embryonic germline.
