Research into cell-to-cell signalling mechanism may lead to new cancer treatments

July 31, 2018

Various mechanisms exist for cells to communicate with each other, and many are essential for development. A team of international researchers looked at how one important family of signalling molecules — Wnt proteins, which orchestrate and control many cell development processes — are transported between cells.

Accurate transmission of Wnt signals is therefore incredibly important; however, the mechanism for this was previously unknown. It was discovered that cell protrusions called cytonemes. play an essential role in transmitting the signal to control the rate of cell division.
