Biologists find cell extrusion, a process that helps organisms eliminated unneeded cells, is triggered when cells can't replicate their DNA during cell division. In humans, extrusion may serve as a way for the body to eliminate cancerous or precancerous cells.
Researchers have discovered a key molecule that allows cancer stem cells to bypass the body's natural immune defenses, spurring the growth and spread of head and neck squamous cell cancers. Their study, conducted in mice, also demonstrates that inhibiting this molecule derails cancer progression and helps eliminate these stem cells.
A team of University of Alberta researchers has discovered a way to use 3-D bioprinting technology to create custom-shaped cartilage for use in surgical procedures. The work aims to make it easier for surgeons to safely restore the features of skin cancer patients living with nasal cartilage defects after surgery.
Researchers have developed a new technology to overcome the inefficiencies and high error rates common among next-generation sequencing techniques that have previously limited their clinical application.
Cancerous tumors thrive on blood, extending their roots deep into the fabric of the tissue of their host. They alter the genetics of surrounding cells and evolve to avoid the protective attacks of immune cells. Now, researchers have developed a way to study the relationship between solid, difficult-to-treat tumors and the microenvironment they create to supp […]
In material physics understanding how systems interact across the interfaces separating them is of central interest. But can physical models clarify similar concepts in living systems, such as cells? Physicists used the framework of disordered elastic systems to study the process of wound healing - the proliferation of cell fronts which eventually join to cl […]
Volunteer firefighters -- who comprise more than 65 percent of the U.S. fire service -- have higher levels of 'forever chemicals,' per- and polyfluoroalkyl substances (PFAS), in their bodies than the general public, according to a new study. It is the first study to evaluate volunteer firefighters' exposure to PFAS.
