caption: The image shows a cross section of a human stomach with a small amount of brown and white cells, which appear to be histiocyte cells. The cells are arranged in a circular pattern, with the largest cell in the center and the smaller cells radiating outward. The colors of the cells range from light brown to dark brown, with some areas appearing darker and others appearing lighter. The background of the image is a light blue, and the cells are surrounded by a thin layer of white.
