Chung Lab Featured in MIT News: Breakthrough Technologies for Protein Labeling of Intact Tissues

We are excited to share that our lab’s latest innovations have been featured in MIT News! The article showcases the new CuRVE and eFLASH technologies, which enable ultrafast and uniform protein labeling across tens of millions of densely packed individual cells in fully intact 3D tissues with unprecedented precision and scalability. This breakthrough addresses critical challenges in studying complex biological systems, such as brain tissue and organoids, where dense cellular environments often hinder detailed protein analysis. By integrating advanced molecular engineering, high-resolution imaging, and computational analysis, our approach allows for more accurate characterization of protein distributions in situ. This innovation significantly improves the speed and accuracy of protein visualization, unlocking new possibilities for biological and neuroscience research.

To develop new treatments or innovative drugs for intractable/incurable diseases, it is crucial to gain deeper understandings of complex human biological systems at various scales. However, the large size and fragile properties of human organs present numerous challenges, causing most research to rely on small, sectioned tissue samples.

In our paper, we present a biotechnology platform for 3D human brain mapping that addresses these challenges by integrating three innovations in Materials Science (mELAST), Mechanical Engineering (MEGAtome), and Computer Science (UNSLICE).

Our advanced polymeric network (mELAST) transforms biological tissues into unique biomaterials that are transparent, elastic, size-adjustable, and chemically and thermally resistant, while preserving endogenous biomolecules. This tissue processing method has enabled us to image various biomolecules at multiple scales from the same, thick, large-scale human brain tissues, providing valuable data on Alzheimer's disease.

We believe this platform can be widely applied to all human organs, laying the foundation for creating a cellular and subcellular level 3D map of the entire human body.
