Fig 2: Localization of glycogen metabolizing enzymes in the decidualized and undecidualized uterine horn in an artificial decidualization model. Immunohistochemistry for hexokinase 1 (HK1), glycogen synthase (GYS), glycogen phosphorylase (PYG), and glucose‐6‐phosphatase (G6PC) in hormonally primed mice. One horn was simulated to decidualize. The unstimulated horn served as a nondecidualized control. n = 4. Scale bar = 50 µm.

Fig 3: Levels of glycogen metabolizing enzymes in uterine horns stimulated to decidualize or left unstimulated. (a–d) Western blots for hexokinase 1 (HK1, a), phospho‐glycogen synthase (pGYS, b), glycogen synthase (GYS, c), and glycogen phosphorylase (PYG, d) in uterine horns stimulated to decidualization with corn oil or unstimulated after hormonal priming. **p < 0.01 relative to unstimulated horn. n = 5.

Fig 4: Immunostaining for glycogen metabolizing enzymes at the implantation site (IS) and the interimplantation site (IIS) on DPC 5.5. Immunohistochemistry for hexokinase 1 (HK1), glycogen synthase (GYS), glycogen phosphorylase (PYG), and glucose‐6‐phosphatase (G6PC) in uteri at DPC 5.5. n = 4. Scale bar = 50 µm. DPC, days postcoitum; Neg, negative control.

Fig 5: Localization of glycogen synthesizing enzymes in the endometrium from proestrus (PROE) until days postcoitum (DPC) 5.5. Immunohistochemistry for hexokinase 1 (HK1) and glycogen synthase (GYS) in uteri collected at PROE, DPC 1.5, DPC 3.5, and DPC 5.5 IIS. n = 4. Scale bar = 50 µm. IIS, interimplantation site; Neg, negative control.
