According to a previous study by the University of Minnesota-led group, cells have the ability to pick up the tightness of their environment, and their capability to move is reliant upon that environment. This stiffness varies from stiff (bone tissue) to soft (fat) to medium stiffness (muscle tissue). Their research demonstrated that the cells can have a “sweet area” of tightness, that isnt too tough or too soft, in which they have much better traction and can move much faster.

In this study, the researchers found that not just does the tightness of the environment effect the speed at which cells move, however it likewise affects the instructions in which they move.
For many years, scientists thought that cells would always gravitate toward a stiffer environment. The University of Minnesota scientists observed for the first time that cells can really move towards a “sweet area” thats more in the middle.
” This discovery challenges the current thinking in the field, which is that cells only approach stiffer environments,” stated David Odde, a teacher at the University of Minnesota Twin Cities Department of Biomedical Engineering and senior author of the study. “I think that this finding will change how people consider this phenomenon. Our mathematical design predicted, and weve revealed through experiments, that cells in fact can move towards the softer side.”
A new research study led by University of Minnesota Twin Cities engineers offers new insights into how cancer cells attack the body, which could help researchers comprehend the disease and establish treatments for it. The above video shows the migration of cancer cells over a period of 24 hours towards a “sweet spot” in the middle of stiff and soft environments, represented by the gray box at the bottom.
During the study, Odde and his team looked at both brain cancer and breast cancer cells. They put cells in between two environments– a stiffer region and a softer area– and observed where they built up.
The research team also discovered that some cells, like the breast cancer cells they studied, have a feedback mechanism that causes them to grip more strongly onto stiffer environments, which explains why many previous studies revealed cells moving to the stiffer side. If you turn that mechanism off genetically, the cells will then gravitate more towards the middle.
” Were generally translating how cancer cells get into tissue,” Odde said. “They dont just move randomly. They really have particular methods which they like to move, and if we can comprehend that, we might be better able to trip them up.”
The next action for the scientists is to utilize this info to build a simulator that demonstrates how cancer cells move through an entire growth, which will assist them better anticipate cells movements based on their environments.
