Mapping the 100 trillion cells that make up your body – Mark Atkinson

There are about 100 trillion cells that make up the human body. A new megascience endeavor will catalog and image each of the 200 or more types of cells from the 80 known organs and identify the genes that are active in these cells.

This new effort follows on the heels of the Human Genome Project that engulfed biology during the 1990s and early 2000s. Now scientists have conceived a new and exciting challenge: to create a cellular map of the entire human body, a project called the Human BioMolecular Atlas Program, or HuBMAP. The University of Florida is one of five participating tissue mapping centers. Here at the UF Center we are charged with mapping the thymus, lymph node, and spleen – all key components of the immune system.
