1. Cell Change and Development Vocabulary: Cell specialization
(specialized and unspecialized cells)
Differentiated Cells
Stem cell
Got Defense? In this electron micrograph,
a human white blood cell is trapping
bacterial cells. This type of cell defends
the body against pathogens by engulfing
them, delivering them to the lysosome of
the cells, and destroying them with the
help of the lysosomal enzymes.

2. Before taking notes on cell development and change,
lets take a look at the following video clip to develop
our background knowledge of cells.

3. Stem cells and differentiation
Elements of Biology: Genetics: The Molecular Basis of Heredity

4. Stem
Cells
Unspecified cells capable of self renewal and differentiate into specialized cells. 

5. Lets meet stem cell guy

6. Differentiate CELL DIFFERENTIATION A normal process in development
in which cells become structurally and functionally different
from one another — for example, nerve, muscle and blood cells.

7. Cellular differentiation is the process by which a less
specialized cell becomes a more specialized cell type.

8. In biology, “specialized” is a term used to explain that a cell has developed into a
specific or particular type of cell.
Unspecialized cell, then, refers to cells which have not yet differentiated (changed) into a specific type of cell.
Specialization

9. Organization: Beginning to end.
In the development of a multicellular organism, differentiated stem cells, multiply to become specialized types of cells multiplying to become tissues, organs, part of an organ system and finally an organism.

10. to cures and/or improvement
What good is stem cell research?
Stem cells leading
to cures and/or improvement
in the human condition.
