Describe what is meant when we say that homologous proteins function interchangeably in the development of mice and flies.

Define embryogenesis.

What is cell proliferation?

What was determined from Long term imaging of zebrafish about embryonic development?

What is gastrulation?

What organism do we study in order to analyse gastrulation?

Describe the main stages of Gastrulation.

What are regulatory genetic elements and what are their role in development?

What is Lineage tracing?

What is experimental embryology?

What is fate determination?

Describe the following types of fate determination:
- Normal fate
- Not determined
- Determined

Describe the following results when cell's of an undetermined cell fate and a determined cell fate are transplanted to altered environments.

What is meant if it is said that a cell is not determined, but specified or committed?

What is often a big cofactor in the ability of a cell to remain determined to the cell function it is destined for?

What is meant when many cells are described as remembering their positional values at certain locations in the body?

How does the Chick model of embryos at 6 days, showing the limb buds with probes to detect expression of Tbx4 and Tbx5 displays features of cell's positional value in the body?

What is an 'inductive interaction' in cell development?

What is asymmetric and symmetric division?

Name 2 origins of asymmetry between sister cells.

What is meant by asymmetry through positive feedback?

Describe the principle of asymmetry in stem cells.

When a stem cell asymmetrically divides, one daughter cell is self-renewed, the other goes on to become a committed transient amplifying cell... what does this mean?

In what way can pluripotent embryonic stem cells be differentiated into diverse cell types after being cultured in vitro?
