Cell motility refers to the ability of cells to move and navigate through their environment. This movement is essential for various biological processes, including development, immune responses, and wound healing. Cells can move by changing their shape, using structures like actin filaments and microtubules to generate force and propel themselves. There are different types of cell motility, such as amoeboid movement, where cells like amoebas extend their membrane to crawl, and ciliary movement, where cells use hair-like structures called cilia to push themselves through fluids. Understanding cell motility is crucial for studying diseases like cancer, where cells may migrate to form tumors.
