Fluorescent micrograph showing cell division in an Arabidopsis seedling used to study in vivo gene expression and cell growth analysis, cell by cell from living tissue Communicate Science: Images of Science
Coloured light micrograph of a 1-week old, nerve cell (neuron) cluster. This cell cluster has been grown in culture. The nerve cell bodies are still grouped together (centre) and the neurites (either axons or dendrites) that will connect the cell bodies to form a network, are beginning to develop (dark lines).
The fluorescence image details the structural organization of the heart of the mosquito Anopheles gambiae. The pericardial cells, labeled red, are pinocytic cells that flank the heart. Cell nuclei are labeled blue. Image Credit: Jonas G. King and Julián F. Hillyer, Department of Biological Sciences, Vanderbilt University.
