Cells interact with each other and with the environment in a very precise and regulated manner. The interactions play a crucial role in many cellular processes and ensure the integrity of tissue structure.
Cell-to-cell interaction forms communication channels for transmitting signals or synchronizing the response, for example in muscle contraction. However, loss of the interactions can result in unfavorable conditions for cell growth and ultimately leads to cancer.
Q-Phase opens the gates for discovering how cells interact together to prevent cell death in unfavorable cultivation conditions.
Moreover, it provides visualization of contact inhibition disruption and its consequences for the development of uncontrolled cell proliferation, tumor formation, and metastasis.
