Our bodies are composed of trillions of specialized cells. It’s the building block that makes us—and unmakes us—in health and disease. The Allen Institute for Cell Science uses diverse technologies and approaches at a large scale to study the cell and its components as an integrated system. Our live imaging data of the major cell structures, tagged by genome-editing human stem cells, is used to develop predictive models of cell states and behavior. One of our founding credos is open science, therefore, all our data and methods at the Allen Cell Explorer are publicly available to scientists worldwide.
