In October 2016, a a collaborative community of world-leading scientists met in London, and discussed how to build a Human Cell Atlas—a collection of maps that will describe and define the cellular basis of health and disease.
Cells are the most fundamental unit of life, yet we know surprisingly little about them. They vary enormously within the body, and express different sets of genes. Without maps of different cell types and where they are located in the body, we cannot describe all their functions and understand the biological networks that direct their activities.
A complete Human Cell Atlas would give us a unique ID card for each cell type, a three-dimensional map of how cell types work together to form tissues, knowledge of how all body systems are connected and insights into how changes in the map influence health and disease. It would allow us to identify which genes associated with disease are active in our bodies and where, and analyze the regulatory mechanisms that govern the production of different cell types.
This has been a key challenge in biology for more than 150 years. New tools such as single-cell genomics have put it within reach. It is an ambitious but achievable goal, and requires an international community of biologists, clinicians, technologists, physicists, computational scientists, software engineers and mathematicians.
