In cell division of high-frequency-selfers in the ciliate Blepharisma japonicum, daughter cells are different in mating-type expression. The anterior daughter cell is mating type I. The posterior daughter cell is mating type II at first and then changes to mating type I after about 24 h. The anteroposterior polarity of predivision cells appears to correlate with the asymmetrical cell division. This work introduces a unicellular organism about the size of microscopic metazoa as a model system for the study of asymmetrical cell division, which is particularly important in developmental processes.
