The image shows developing eggs in a Drosophila ovary stained for two types of signaling protein (red and green) involved in the establishment of the anterior-posterior polarity of the egg.

Presynaptic contacts are abundant on both cell bodies and the dendritic arbor of cultured hippocampal neurons after 15 days in vitro. Neurons were immunostained for MAP2, a microtubule associated pro...
