20.2 Stem cells and totipency

Cell differentiation and specialisation?

Differentiation:

This is the process where a less specialized cell, like a stem cell, develops into a more specialized cell with a specific structure and function.

Specialization:

The result of differentiation, where a cell gains unique features and capabilities to carry out a particular task.

Totipency:

• Totipotent cells are cells which can mature into any body cell

Ways in which genes are prevented from expressing themselves:

What are stem cells?

Stem cells originate from various sources in animals?

Totipotent stem cells:

Pluripotent stem cells:

Multipotent stem cells

Unipotent stem cells:

Induced pluripotent stem cells
