Integrated metabolomic and transcriptomic analyses reveal that glutamine promotes chicken primordial germ cell-like cell specification potentially through α-ketoglutarate
Glutamine promotes the specification of chicken PGCLC and correlates with alterations in cellular metabolism and increased H3K4me2 levels during differentiation, providing new insights into the metabolic basis of PGC formation and a foundation for improving PGC culture and expansion in poultry.
