A3, B3, C3) Stars represent the MDZ, and the indicated areas are also shown at a higher magnification; scale bars: 50 μm. A4, B4, C4) Arrowheads represent PZ, and the indicated areas are also shown at a higher magnification; scale bars: 50 μm. All the sections are representative of the results for at least 3 individuals at the same time point.
