There isn't a single type of cell that never divides. Cell division is fundamental to life, and most cells are capable of it under the right conditions.

However, there are some cells that rarely or never divide in a mature organism, like:

* Mature nerve cells (neurons): While some neurons can regenerate, many are considered post-mitotic, meaning they don't divide after they reach maturity.

* Muscle cells (myocytes): Muscle cells can grow in size, but they generally don't divide after development.

* Heart muscle cells (cardiomyocytes): These cells are also largely post-mitotic.

* Red blood cells (erythrocytes): Mature red blood cells lack a nucleus and other organelles, making them incapable of division.

It's important to remember that even in these examples, there may be some limited cell division under special circumstances, such as injury or disease.
