Stem Cell Webquest

What are stem cells and why are they important? Stem cells have a amazing rate of growing into a lot of different cell types during early life and growth. The are used as sort of a defensive/repair system in the body that they live in. They do not have a limit of helping the body while it is still alive. Every stem cell can create either two stem cells, two specialized cells, or one specialized and stem cell. By specialized cell I mean any cell that helps or destroys things in the body. Such as a lung cell or a liver cell that goes and helps the organs.

Webquest Key Terms

Cell-based therapies- Treatment in which stem cells are induced to differentiate into the specific cell type required to repair damaged or destroyed cells or tissues.

Differentiation- The process whereby an unspecialized embryonic cell acquires the features of a specialized cell such as a heart, liver, or muscle cell. Differentiation is controlled by the interaction of a cell's genes with the physical and chemical conditions outside the cell, usually through signaling pathways involving proteins embedded in the cell surface.

Embryonic stem cell line-Embryonic stem cells, which have been cultured under in vitro conditions that allow proliferation without differentiation for months to years.

Proliferation- Expansion of the number of cells by the continuous division of single cells into two identical daughter cells.

Plasticity- The capacity of organisms with the same genotype to vary in developmental pattern, in phenotype, or in behavior according to varying environmental conditions.

Pluripotent- Not fixed as to developmental potentialities, capable of differentiating into one of many cell types.
