Background:
- Retinal morphogenesis and cellular interactions are not fully understood.
- Precise mapping of gene expression at single-cell spatial resolution is needed for comprehensive characterization.
Purpose of the Study:
- To create a spatial transcriptomic (ST) resource for the developing human retina across six stages.
- To characterize cell-type-specific expression profiles and spatiotemporal dynamics during retinal development.
Main Methods:
- Combined spatial and single-cell transcriptomic data analysis.
- Catalogued ST spots into spatial domains with associated expression signatures.
- Reconstructed spatial cellular communication networks.
Main Results:
