Spatial Transcriptomics, Proteomics, and Epigenomics as Tools in Tissue Engineering and Regenerative Medicine.

Area of Science:

• Multi-omics spatial technologies
• Cellular and tissue analysis

Background:

• Spatial transcriptomics, proteomics, and epigenomics offer high-resolution insights into cellular functions and interactions.
• These techniques enable the study of gene and protein expression at the single-cell level, identifying cellular heterogeneity and rare cell populations.

Purpose of the Study:

• To explore the capabilities and limitations of spatial transcriptomics, proteomics, and epigenomics.
• To understand how these technologies can advance the study of bioengineered tissues and disease processes.
• To highlight the potential of integrating these multi-omics approaches for improved tissue engineering.

Main Methods:

• Spatial transcriptomics for mapping gene activity within tissue architecture.
• Spatial proteomics for analyzing protein distribution.
• Spatial epigenomics for understanding gene regulation in tissues.
• Single-cell analysis to investigate cellular heterogeneity.

Main Results:

• These methods allow simultaneous analysis of thousands of cells, providing deep transcriptomic views of complex tissues.
• Spatial transcriptomics preserves tissue architecture, enabling mapping of gene activity across regions.
• Spatial proteomics and epigenomics provide data on protein distribution and gene regulatory aspects, respectively.

Conclusions:

• Despite limitations like technical noise and data interpretation challenges, these spatial multi-omics technologies are rapidly advancing.
• Combining spatial transcriptomics, proteomics, and epigenomics promises a comprehensive understanding of cell function and tissue organization.
• Integration of these techniques is expected to improve cell guidance in tissue-engineered constructs and enhance tissue technology products.
