Note: Proteins changed from E15.5 fetuses to newborn rats and proteins changed with development in literature were noted using an increasing arrow (↑) / decreasing arrow (↓). Proteins without information on expression changes are indicated with “#”. Protein expression that increased during the early stage of development and decreases in the late stage of development is indicated with “∧”.
