In organisms consisting of multiple cell types, diverse cells with different functions and structures develop as we grow and age. The organization and variability of these cells have a profound impact on the function of different tissues, process of aging, and emergence of diseases and conditions. Recently developed technologies are allowing researchers to explore cells on the individual level. The Human BioMolecular Atlas Platform (HuBMAP) program aims to facilitate research on single cells within tissues by building a central platform to bring together data from around the world and making it accessible to the scientific community. The HuBMAP platform will synthesize a wide variety of data to build detailed and comprehensive biomolecular maps of human tissues.
