Summary Human tissue phenotyping generates complex spatial information from numerous imaging modalities, yet images typically become static figures for publication, and original data and metadata are rarely available. While comprehensive image maps exist for some organs, most resources have limited support for multiplexed imaging or have non-intuitive user interfaces. Therefore, we built a Pancreatlas resource that integrates several technologies into a unique interface, allowing users to access richly annotated web pages, drill down to individual images, and deeply explore data online. The current version of Pancreatlas contains over 800 unique images acquired by whole-slide scanning, confocal microscopy, and imaging mass cytometry, and is available at https://www.pancreatlas.org. To create this human pancreas-specific biological imaging resource, we developed a React-based web application and Python-based application programming interface, collectively called Flexible Framework for Integrating and Navigating Data (FFIND), which can be adapted beyond Pancreatlas to meet countless imaging or other structured data-management needs.
Deep phenotyping of human tissues generates complex spatial information from a variety of experimental modalities, yet images are typically condensed into small, static figures for publication and contain substantial data and metadata that never become widely available to the scientific community. Because image files are usually large, data is not easily shared or transferable even amongst collaborating researchers. While comprehensive image maps are available for some organs such as the brain, most resources are limited in their ability to accommodate multiplexed imaging with any degree of user interactivity. In recognition of this unmet need, we developed an online resource called Pancreatlas™ that integrates information technology infrastructure with enterprise imaging storage and visualization solutions. Through our custom interface, users can access curated, easy-to-navigate web pages, drill down to individual images, and deeply interact with them – all online, without lengthy downloads or software installation. Images are annotated with structured metadata, enabling users to dynamically build image datasets with biological and clinical relevance. The first version of Pancreatlas (v1.1) contains over 700 unique images acquired as whole-slide scans, confocal images, and imaging mass spectrometry, and is available at http://www.pancreatlas.org. While the overall system – entitled Flexible Framework for Integrating and Navigating Data (FFIND) – was deployed as a human pancreas-specific biological imaging resource, it can be configured to meet a myriad of imaging or other modular data management needs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
