Asian single-cell genomics data with age-related metadata


The Chan Zuckerberg Initiative (CZI) supports several projects involving Asian single-cell genomics data with age-related metadata through its CELLxGENE Discover platform and affiliated research networks. Here are key resources:


---


## **Asian Immune Diversity Atlas (AIDA)**  

**Focus**: Immune cell variation across six Asian populations (Chinese, Japanese, Korean, Indian, Malay, Thai)[1][4].  

**Methods**:  

- Single-cell transcriptomics (5’ scRNA-seq)  

- TCR/BCR profiling  

- Enhancer RNA analysis  


**Cohort**:  

- Over 2,000 healthy individuals spanning 20 ancestrally diverse Asian groups  

- Includes non-urban and underrepresented populations  

- Analyzes effects of **age**, ancestry, sex, and environmental factors on immune phenotypes[4].  


**Access**: Data will contribute to the Human Cell Atlas and likely integrate with CZ CELLxGENE Discover[1][4].

## **CZ CELLxGENE Discover Platform**  

**Key Features**:  

- Hosts >85 million single cells from 1,317 datasets  

- Includes metadata filters for **age**, cell type, and tissue[5][6].  

- Tools for analysis, visualization, and AI model training  


**Relevant Data**:  

- Search using filters like `organism: Homo sapiens`, `tissue: blood`, and `ethnicity: Asian`  

- Age metadata available for many datasets (e.g., developmental stages, adult vs. aging)[5][6][9].  


---


## **Billion Cells Project**  

**Partners**: 10x Genomics, Ultima Genomics  

**Scope**:  

- Includes primary human cell models, potentially covering Asian cohorts  

- Focuses on genetic perturbations across cell types and tissues[2][7].

## **How to Access**  

1. Visit [CZ CELLxGENE Discover](https://chanzuckerberg.github.io/cellxgene-census/)  

2. Use the Census API or PyTorch loaders for large-scale analysis[6][9].  

3. Filter datasets using variables like `donor_age` and `ethnicity`.  


For AIDA-specific data, monitor updates via the [Human Cell Atlas-Asia network](https://chanzuckerberg.com/science/programs-resources/cell-science/ancestry-networks/)[1][4].

Single-cell RNA sequencing reveals the molecular features of peripheral blood immune cells in children, adults and centenarians

 1,2,3 4 1,2,3 4 1,2 1,2,3 1,2 1,2,3 1,2 1,2 1,2,3 1,2,3 1,2,3,* 1,2,3,*
PMCID: PMC9871912  PMID: 36703979

Age groups in single-cell genomics studies are often categorized based on developmental and aging stages. Here are examples from relevant datasets:

### **Age Groups in Single-Cell Genomics Studies**
1. **Multi-Age PBMC Profile (PMC9871912)**
   - **Children (Group 1, G1)**: 1–12 years old.
   - **Young Adults (Group 2, G2)**: 20–30 years old.
   - **Middle-Aged Adults (Group 3, G3)**: 30–60 years old.
   - **Aged Adults (Group 4, G4)**: 60–80 years old.
   - **Supercentenarians (Group 5, G5)**: >110 years old[4].

2. **Transcriptomic Age Profiling Study**
   - Age groups were used to predict the chronological age of cells. Differences were observed between adolescents, adults, and aged adults across various cell types[1].

3. **PanSci Dataset**
   - Includes cellular data across five life stages in mice, showing age-specific shifts in cell populations across organs. This approach might be mirrored in human studies for similar age group classifications[6].

These age groups provide a framework for analyzing cellular changes and aging processes across different life stages.
