FANTOM, an international scientific consortium led by RIKEN, has now created the first extensive atlas of microRNA expression in human primary . Leveraging the collection of RNA samples established as part of the fifth edition of FANTOM, the team has sequenced microRNA libraries of hundreds of human samples, including many cell types for which the microRNA presence had never been investigated before.

By using in situ hybridization, HCS Pharma is able to stain microRNA on cell cultures and FFPE (Formalin-fixed, paraffin-embedded) histology sections, for an in situ visualization, localization, and quantification.

A study led by Emma Lundberg* presents an extensive work  on the intra cellular localization of thousands of human proteins. The team generated more than 300,000 images to systematically resolve the spatial distribution of human proteins in cultivated cell lines.

Here is the abstract of this article, published in Science:

Resolving the spatial distribution of the human proteome at a subcellular level greatly increases our understanding of human biology and disease. Here, we present a comprehensive image-based map of the subcellular protein distribution, the Cell Atlas, built by integrating transcriptomics and antibody-based immunofluorescence microscopy with validation by mass spectrometry. Mapping the in situ localization of 12,003 human proteins at a single-cell level to 30 subcellular structures enabled the definition of 13 major organelle proteomes. Exploration of the proteomes reveals single-cell variations of abundance or spatial distribution, and localization of approximately half of the proteins to multiple compartments. This subcellular map can be used to refine existing protein-protein interaction networks and provides an important resource to deconvolute the highly complex architecture of the human cell.

The Cell Atlas is an open access resource: everybody can explore it !
