In certain specialized cells, however, the smooth ER is abundant and has additional functions.

This animation describes the specialized cells that make up each part of the conduction system, and how they work together to create the heartbeat.

The immediate research task is to learn how stem cells differentiate into more specialized cells.

Scientists say the theory behind stem cells is correct: the cells, in principle, can become any specialized cell of the body.

The protein helps prime stem cells to become specialized cells in mice.

Most of these are specialized cells that are sensitive to:

Whenever cloning had been tried with more specialized cells in the past, it had ended in failure.

It is in many species accumulated in specialized cells called guanocytes.

The bladder is lined with specialized cells called transitional cells.

These exchanges occur across specialized epithelial cells and through a filtration process in the kidneys.
