Fabrication of the semi-opened MCO scaffold. a. Amh antibodies identified the physiological structure of mouse ovary follicles. The scale bar was 200 μm. b. The structure of the MCO scaffold with gelatin microspheres, the scale bar was 500 μm. c. The structure of the MCO scaffold after the dissolution of gelatin microspheres, the bar was 500 μm. d. The SEM image of a mouse ovary by tearing off a piece of the surface epithelium, the scale bar was 500 μm (left panel) and 100 μm (right panel). e. The SEM image of the MCO scaffold after the dissolution of gelatin microspheres, the scale bar was 1 mm (left panel) and 100 μm (right panel).
