Official Chinese Academy of Sciences Biography

Cytologist. Born in Zhenhai, Zhejiang Province. Graduated from the premedical course of Tongji Medical and Technical College in 1921. Received Sc.D. from Tuebingen University, Germany in 1928. Research professor and honorary director, Institute of Biophysics, Chinese Academy of Sciences.

During the intersex changing of Chirocephalus, Bei observed the phenomenon of cell reformation and investigated cell reformation in the early development of chick embryo, hemopoietic system of mice (bone marrow), nodule bacteria and Chlamydia trachomatis. He proved that the existence cell reformation is an objective reality, especially in yolk granules and cytoplasm of early development of Chirocephalus and chick embryo and extracted chromatin from yolk granules. Formerly, he studied life history, development, cell-constancy, regeneration, structure and behavior of chromosomes of nematode. He also studied chromatophore activity of crustacean in relation to different temperature and different concentrations of Eyestalk-extract, structural and functional changes of Corpus allatum and Corpus cardiacum of Chironomus larvae during metamorphosis, and annelid regeneration, relation between regeneration and natural fission, relation between fission and disintegration at different temperatures, etc..

He became Member of the Chinese Academy of Sciences in 1955.
