Takumi Development Phases (IMAGE) Kobe University Caption The Kobe University-led research team identified a group of proteins that undergo a phase of change where some are produced more and others are produced less as time passes. They also found that the timing of this change is different in mice and marmosets: What happens in mice two weeks after birth happens before or around birth in marmosets. In addition, marmosets have a second phase of protein changes that mice don’t have. Credit KAIZUKA Takeshi Usage Restrictions Credit must be given to the creator.
