Researchers from the Laboratory of Cell and Developmental Biology at the Department of Biological Sciences, University of Cyprus, have published a significant study in Nature Communications, revealing that short-lived intracellular calcium surges act as critical "signals" for the integration of new cells into tissues. This discovery was shared in a press release from the University.

According to the release, this fundamental biological process is essential for the development, renewal, and repair of tissues throughout the body.

The study, led by Dr. Neophytos Christodoulou and Professor Dr. Paris Skourides, found that cells destined for tissue integration activate brief calcium signals before appearing on the tissue surface. Without these signals, the new cells fail to integrate properly—posing a risk to tissue functionality.

The Mechanism Behind Successful Cell Integration

The researchers also identified the internal cellular circuit responsible for triggering these signals. This circuit stabilizes the cell’s cytoskeleton and enables successful cell integration into tissue structures.

The study offers new insights into a vital biological mechanism that takes place continuously within the human body. Organs such as the lungs, skin, and intestines undergo constant renewal, incorporating new cells to replace the old.

Implications for Regenerative Medicine and Chronic Disease Treatment

Understanding how this process is regulated opens new avenues for regenerative medicine and therapies targeting chronic diseases where tissue renewal is impaired.

“This study is another example of the high-level research being conducted at the University of Cyprus and strengthens its international presence in the field of biomedical science,” the University press release states.

The research was funded by the Research and Innovation Foundation.
