Unlocking Healing Secrets: How Injured Cells ‘Vomit’ Waste to Speed Up Recovery, New Study Reveals

When cells get injured, they can essentially “throw up” their insides to heal faster, according to new research. This process helps them recover but may also be linked to diseases like cancer.

The study focuses on a newly identified cellular response called paligenosis. This is when mature cells act more like young, stem cell-like cells after an injury. The researchers found that injured cells can quickly eliminate waste in a process they named “cathartocytosis.” This swift action may help them transition to a more primitive state needed for repair.

Jeffrey W. Brown, a gastroenterologist at Washington University, explains, “After injury, the cell needs to repair itself, but its usual machinery can get in the way.” By rapidly clearing out waste, the cells can focus on healing more effectively.

At first, it was thought these cleanses happened inside specialized compartments called lysosomes. However, the team noticed debris outside the cells, hinting that something else was occurring.

Using a mouse model of stomach injury, the researchers confirmed that this “vomiting” reaction is a common behavior for cells undergoing paligenosis, not just a random occurrence.

While this approach allows for quick healing, it comes with risks. The rapid removal of waste can lead to complications such as chronic inflammation and may increase the risk of cancer, according to Jason C. Mills from Baylor College of Medicine. He notes, “Injuries can spur inflammation, which may allow harmful mutations to expand.”

These findings have implications beyond cell biology. They suggest that understanding this process could help identify precancerous conditions more effectively. If doctors can better grasp how cathartocytosis works, they might find ways to promote healing while preventing potential cancer formation.

The study adds to existing research on how cells manage injury and repair. It also opens up discussions about future treatments for diseases linked to cellular waste disposal.

For more detailed insights, the study was published in Cell Reports.
