Histological observations of reticular fibers during endometrial breakdown in the mouse menstrual-like model. A1-A5) Representative histomorphological features at different time points during mouse endometrial breakdown; M, mature decidual-like zone (MDZ); P, predecidual-like zone; scale bars: 400 μm. B1-B5) higher magnification of the area indicated by the small blank boxes in A1-A5; scale bars: 50 μm. C1-C5) Reticular fiber staining; the small blank boxes indicates the PZ and MDZ, also shown at higher magnification, scale bars: 400 μm. D1-D5) The symbols (stars and arrows) represent the MDZ and PZ, respectively, and the indicated areas are shown at higher magnification (E1-E5, F1-F5); scale bars: 100 μm. E1-E5) Higher magnification of the areas indicated by the symbol * in D1-D5, showing the MDZ; scale bars: 50 μm. F1-F5) Higher magnification of the areas indicated by arrows in D1-D5, showing the PZ; scale bars: 50 μm.
