# A Single-Cell Transcriptomic Atlas of Human Skin Aging
This dataset contains structured tables extracted from the supplementary materials of the publication:
> **"A single-cell transcriptomic atlas of human skin aging"**
> *Cell Reports, 2020*
> DOI: [10.1016/j.celrep.2020.108132](https://doi.org/10.1016/j.celrep.2020.108132)
The data has been processed from the publication PDF into a `.parquet` file to facilitate downstream analysis and integration into machine learning workflows.

## 📦 Dataset Description
The dataset includes multiple tables capturing aging-related transcriptomic changes in human skin tissue at the single-cell level. Tables were extracted using PDF parsing tools and contain gene expression summaries and annotations useful for skin biology and aging research.
---
## 🔧 Usage Instructions
To load the Parquet file in Python:
```python
import pandas as pd
df = pd.read_parquet("skin_aging_data.parquet")
print(df.head())
```
---
## 🚀 Use Cases
- Aging biomarker discovery in dermal and epidermal compartments
- Training skin-specific biological age predictors
- Integrating skin aging profiles with other tissue atlases
- Cross-species comparison of skin aging signatures
- Evaluation of anti-aging interventions at single-cell resolution
