| Study Title | Mannose is crucial for mesoderm specification and symmetry breaking in gastruloids. |
| Study Summary | Patterning and growth are fundamental features of embryonic development that must be tightly coordinated. To understand how metabolism impacts early mesoderm development, we used mouse embryonic stem cell-derived gastruloids, that co-expressed glucose transporters with the mesodermal marker T/Bra. While the glucose mimic, 2-deoxy-D-glucose (2-DG), blocked T/Bra expression and abolished axial elongation in gastruloids, removal of glucose did not phenocopy 2-DG treatment despite a decline in glycolytic intermediates occurring under both conditions. As 2-DG could also act as a competitive inhibitor of mannose in protein glycosylation, we added mannose together with 2-DG and found that it could rescue the mesoderm specification both in vivo and in vitro. We further showed that blocking production and intracellular recycling of mannose abrogated mesoderm specification. Proteomics analysis revealed that mannose reversed glycosylation of the Wnt pathway regulator, Secreted Frizzled Receptor, Frzb. Our study showed how mannose is crucial for mesoderm specification in gastruloids. |
