There is provided a method of an animal model experiment to observe cells implanted to an experimental small animal in which the position or spatial spread only of the implanted cells can be detected and observed with time progress and with sufficient accuracy while a plurality of kinds of the implanted cells can be distinguished from one another. The inventive method of in vivo detecting implanted cells implanted into the body of a small animal comprises steps of preparing cells used as the implanted cells into which a gene expressing a tag of a part of a peptide or a protein on a cell membrane is introduced; implanting the implanted cells to an arbitrary site of the small animal; and detecting the tags in the small animal. The tags may be detected by dosing the small animal with fluorescently labeled antibodies to the tags and imaging the fluorescence from the antibodies.
