MIT Develops Noninvasive Method to Detect 'Zombie Cells
Developing
In Short: MIT researchers have developed a noninvasive method to detect senescent cells, often referred to as 'zombie cells,' which can contribute to age-related diseases such as cancer, tissue degeneration, and inflammatory conditions.
MIT researchers have developed a noninvasive method to detect senescent cells, often referred to as 'zombie cells,' which can contribute to age-related diseases such as cancer, tissue degeneration, and inflammatory conditions. This advance is part of a National Institutes of Health initiative called the Cellular Senescence Network, aimed at understanding the effects of senescent cells and developing therapies to combat them.
Senescent cells are cells that stop dividing but do not die, undergoing significant changes in their shape, metabolic processes, and gene expression profiles. These cells can accumulate over time and contribute to various age-related disorders. However, identifying these cells typically requires a process that destroys them, making noninvasive detection challenging.
The new method, based on Raman microscopy, allows researchers to reveal the biochemical composition of cells without causing harm. By combining Raman microscopy with gene expression data from the same cells, the researchers were able to identify unique 'barcodes' that can quickly identify senescent cells.
In their study, the researchers focused on senescent skin cells and discovered that cellular pathways associated with muscle contraction and the remodeling of collagen and the extracellular matrix were significantly affected. This finding could provide insights into how senescent cells contribute to age-related changes in tissues.
The study was conducted using mouse cells, but the researchers are now working on adapting the method for use with human tissue. This could lead to better diagnostic tools and potential treatments for age-related diseases.
The ability to noninvasively detect senescent cells could be a significant step forward in understanding and addressing the cellular changes that contribute to aging and age-related diseases.
What this adds
This study builds on previous research by MIT researchers who developed an AI-powered barcode to detect senescent cells, but the new method uses Raman microscopy for noninvasive detection.
Background
MIT researchers have developed an AI-powered barcode that can identify senescent cells, often referred to as 'zombie cells,' in aging tissues.
MIT researchers have developed a new method to detect 'zombie cells,' or senescent cells, which can contribute to age-related diseases such as cancer and tissue degeneration.
What's still developing
- However, those proteins can only be identified using a process that ends up destroying the cells.
