Study TitleAtlas of fetal metabolism during mid-to-late gestation and diabetic pregnancy. Dynamic Labelling experiment.
Study SummaryMounting evidence supports an instructive role for metabolism in stem cell fate decisions. However, much is yet unknown about how fetal metabolism changes during mammalian development and how altered maternal metabolism shapes fetal metabolism. Here, we present a descriptive atlas of in vivo fetal murine metabolism during mid-to-late gestation in normal and diabetic pregnancy. Using 13C-glucose and LC-MS, we profiled the metabolism of fetal brains, hearts, livers, and placentas harvested from pregnant dams between embryonic days (E)10.5 and 18.5. Comparative analysis of our large metabolomics dataset revealed metabolic features specific to fetal tissues developed under a hyperglycemic environment as well as metabolic signatures that may denote developmental transitions during euglycemic development. We observed sorbitol accumulation in fetal tissues and altered neurotransmitter levels in fetal brains isolated from dams with maternal hyperglycemia. Tracing 13C-glucose revealed disparate nutrient sourcing in fetuses depending on maternal glycemic states. Regardless of glycemic state, histidine-derived metabolites accumulated during late development in fetal tissues and maternal plasma. Our rich dataset presents a comprehensive overview of in vivo fetal tissue metabolism and alterations occurring as a result of maternal hyperglycemia.

Sample Preparation:

Sampleprep ID:SP002997
Sampleprep Summary:Fetal tissue extraction: Following infusion, mice were euthanized and blood was collected via heart puncture. Fetal tissues (placenta, brain, liver, and heart) were dissected in ice-cold sterile PBS. Immediately after dissection, weight was recorded and fetal tissue was placed in a pre-filled bead mill tube containing metal beads and 500 µL of methanol:water (80:20) solution kept cold on dry ice. Fetal tissues were homogenized using a Fisherbrand™ Bead Mill Homogenizer. Samples were spun twice at >17,000 g (4 °C) to remove precipitated cell material (protein/DNA). Supernatants were collected, transferred to a clean tube, and evaporated using a Nitrogen evaporator (Organomation). Evaporated samples were stored at -80 °C. Pellets containing protein/DNA were dried on a heat block (55 °C) and stored at -80 °C. Serum extraction: Collected blood was centrifuged at 5,000g to collect serum. Serum was snap frozen in liquid nitrogen and stored until extraction. For metabolite extraction 5 µL serum was mixed with 500 µL 100% MeOH (-80 °C). Samples were centrifuged for 10 min at >17,000 g (4 °C) and 450 µL of each sample evaporated using a Nitrogen evaporator (Organomation). Evaporated samples were stored at -80 °C.
