Embryos carry an elegance and beauty that is often hidden to the eye. Genetic techniques that mark select cells and follow their fate through time allow us to reveal forms, accents and movements otherwise unknown.
Proteins participate in almost all activities of the brain. A brain cell's identity can be revealed through the specialized proteins that it has been programmed to make. The numerous proteins of the brain can be visualized using specialized techniques that rely on differential coloring to identify each unique protein.
The most defining moments of life are the first. Sperm fuses with egg, zygote forms, cells divide exponentially and the early embryo emerges as morphogenesis follows in well programmed sequential steps.
