The Human developmental cell atlas (HDCA) is the Swedish effort within the human cell atlas (HCA), one of the largest international scientific projects. The projects aim is to create a comprehensive molecular atlas of human prenatal development at the molecular resolution using state-of-the-art technologies such as single-cell RNA-seq, Spatial Transcriptomics, in situ sequencing in order to provide deeper insight into how variations and deviations contribute to health and disease. - We will use this project to compute and store NON-SENSITIVE data produced within the atlas, providing machine-readable access to curated public count matricies on mouse and human development (i.e. from GEO and ENA).
