Breakout Sessions

Clinical Metadata   
Data Architecture and Integration    Temporal Analysis: Development and Pediatric    Multiplex Molecular Profiling Tools    Spatial Profiling Tools   
a. What is the scope of "clinical" metadata? Developing a roadmap of establishing “clinical” metadataa. Common interfaces There are several different cell atlas’ing initiatives which are all building portals and storage solutions for their data. What common interfaces are needed to minimize any access barriers across multiple projectsa. Organ-based or anatomical unit-based atlas How do we achieve V1 development atlasa. Imaging-based techniques Imaging- based techniques at all scales for multimodal molecular profilinga. Antibody-based imaging methods e.g., staining using fluorochromes, metal-chelates, etc., in an antibody-based manner
b. Core clinical metadata How do we achieve core clinical metadata standards across diverse tissue types, tissue collection methods, and tissue collection sites. (sample level vs patient level)?b. Data Storage and Data Movementb. Engaging developmental biology community Expertise in developmental biologyb. Single-cell sequencing-based techniques Spanning the Central Dogmab. Imaging-based transcriptomics methods e.g., multiplexed FISH and in situ sequencing methods
c. Levels of Metadata How to manage the clinical metadata data outside of the core?c. Data format standardsc. What biology can we learn from development atlas What are important questions?c. Sequencing-based spatial measurements (e.g. ST)
d. Review process for Clinical Metadata The process to gain consensusd. Authentication for accessd. Relevance of development to pediatric and adult health/diseased. Multi-omic spatial data and integratio
e. Sample ID Naming Conventions Naming conventions to account for patient or subject, multiple samples per subject, many time points (longitudinal studies) and spatial attributese. Ethics relating to development atlas
f. Age resolution for pediatric and development atlas
Common Coordinate Frameworks    Metadata - Schemas & Ontologies    Tissue Collection & Processing    Multiplex Molecular Profiling Analysis    Spatial Profiling Analysis   
a. CCF User Interfaces Major anatomical terms and 3D structures in human, Major human cell types, sizes, and “calling cards”, Taxonomy nomenclatures and standardizationa. Common metadata schemas and their use casesa. Tissue types and purpose What type of tissue are you collecting and for what purpose?a. Computational Challenges Given a set of multimodal assays, what are computational challenges in processing and extracting data from these multiplexed molecular profiles (e.g. ATAC-seq and RNA-seq)?a. Highly multiplexed image analysis (antibody-based: e.g. CyCIF, IMC, MIBI, CODEX etc.)
b. The role of computational physiologyb. Federation of metadata standards efforts Goals for collaboration and unificationb. Characterization of tissue processingb. Standards and provenance What process can be used to standardize data, metadata, analyses, and provenance to facilitate sharing?

c. The role of Functional Tissue Units (FTUs)c. Anatomy and CCF in metadata How should we reference anatomy and common coordinate frameworks in metadata?c. Measures for QA/QC What are the measures you take for quality assessment and control of the tissue collected?c. Pipeline Validation and Dissemination What could be done to validate pipelines?c. Generation of 3D reference volumes & frameworks Generation of 3D reference volumes / frameworks of different tissues for registering spatial data

Developing informatics and models c. Target selection and proteins of interest (POI)c. Genetic basis of cellular identity
d. QC and “validation” of sc/snRNA-seq data QC and “validation” of sc/snRNA-seq data are important to establish confidence in a datasetd. Sharing Protocols and Analysis Pipelinesd. Variation in imaging technologies Source of pre-analytical variation in imaging technologies that use affinity reagents/Ab’sd. Cellular dynamics, plasticity, perturbations
e. Biobank testing Cross-consortium sample studies need to be tested - there are many biobanks with expertise in different arease. Maintaining Repeatable Analysis Over Time
f. Common benchmarking Whether a biospecimen or a dataset, common benchmarking is necessary to establish qualityf. QA/QC of Releases
Ethics and Diversity
