How might abnormalities in cellular adhesion contribute to cancer?
Thus, context-dependent adhesion molecule switching not only contributes to cancer cell motility, but also promotes their proliferation and survival ability in the bloodstream, thereby increasing the probability of distant metastases forming.
Why is cellular adhesion important?
Cell adhesion is involved in stimulating signals that regulate cell differentiation, cell cycle, cell migration, and cell survival . … Cell adhesion is also essential in cell communication and regulation, and becomes of fundamental importance in the development and maintenance of tissues.
Do cancer cells adhere?
Multiple and diverse cell adhesion molecules take part in intercellular and cell-extracellular matrix interactions of cancer. Cancer progression is a multi-step process in which some adhesion molecules play a pivotal role in the development of recurrent, invasive, and distant metastasis.
What are the worst types of cancer?

How do cells in your body stay together?
Cells adhere to each other and to the extracellular matrix through cell-surface proteins called cell adhesion molecules (CAMs)—a category that includes the transmembrane adhesion proteins we have already discussed. CAMs can be cell-cell adhesion molecules or cell-matrix adhesion molecules.
What class of molecules is responsible for cell-cell adhesion?
Within tissues, adhesive molecules allow cells to maintain contact with one another and with structures in the extracellular matrix. One especially important class of adhesive molecules is the integrins. Integrins are more than just mechanical links, however: They also relay signals both to and from cells.
