Recently, led by Chinese scientists, 6 countries and 32 scientific research teams have jointly completed the world’s first batch of life space-time maps. For the first time, scientists have mapped the temporal and spatial maps of embryonic development or organs of four model organisms: mice, zebrafish, fruit flies and Arabidopsis, and published them online in the journal Cell and its sub journal developmental cell. The research has passed the ethical review and strictly followed the corresponding laws, regulations and ethical norms.
