This is a cell that has differentiated. Embryonic stem cells are undifferentiated meaing they have the ability to become any type of cell in the body. As development progresses and cells divid. Different cells take on different functions. And are thus said to be specialed. Hope that is what you were asking.

When an organism starts from a single cell, like a fertilized gamete, that cell has the potential to become ANY and EVERY cell in the body. This is called "pluripoteniality," and those are the famous "stem cells" that everybody's talking about! As the cell divides and divides again, different parts of the embryo take on different characteristics depending on their location. The way this happens is that some genes are turned "on," and other genes are turned "off." At some point in this process, a cell reaches a "point of no return," where it can no longer reverse its direction and become something else. When a cell becomes what it is destined to be -- say a liver cell or a neuron -- and cannot anymore be anything else, it is called a "specialized cell."

It is as it sounds a cell which does a specific task. Some examples would be nerve cells, red blood cells and epithelial cells.
If you need to know more about it and how specialised cells are formed then the word you need to look up is differentiation.

Specialized cell/cells is a cell/cells that is/are made specially for the job it is/they are supposed to perform.

blood cell is specialized, muscle cell is specialized, nerve cell is specialized. they all have a single function.
