Summary: During the 25 years since 1961, over 40,000 cases of human conceptuses were collected and examined systematically. Most specimens were procured after induced abortion performed on healthy pregnancies. Important embryological and teratological information has been derived from the embryo collection. In the present paper, the following five projects will be selected from our original works and reviewed briefly; (1) pre-embryos prior to major organogenesis, (2) normal histology of human embryos and fetal organs, (3) inconsistent relationship between embryonic age and developmental stage, (4) teratological studies in the early intrauterine population, and (5) development of human and rat embryonic tissues grafted into athymic (nude) mice.
