Fig. 5: An evolutionary conserved switch from bivalent to glycolytic metabolism in mammalian development upon embryonic disc formation.

From: A hexa-species transcriptome atlas of mammalian embryogenesis delineates metabolic regulation across three different implantation modes

Fig. 5

Single-cell RNA-seq data from six species stage-matched according to the Carnegie system allowed elucidation of the transcriptional programme of metabolic enzymes. This metabolic programme is characterised by low glycolytic activity during cleavage, followed by a peak in OxPhos during the formation of the blastocyst (CS3) and an increase in glycolytic flux at the time of embryonic disc formation (CS5), regardless of species or time of implantation.
