MOLECULAR BIOLOGY OF DIFFERENTIATION

(2)

Factors involved in triggering cell differentiation:

1. environmental influences 2. cell signaling

3. level of development of the organism

(3)

The role of environment in cell differentiation

(4)

• Cell’s internal environmental factors

• Cell’s external environmental factors

affect the gene expression and

cell differentiation

(5)

Internal Factors

• affect cell specialization

• affect manufacture of proteins

(6)

Influences from the environment of the organism can affect

• cell signaling

• gene expression

• cell differentiation

change, stop or disrupt the process.

(7)

Environmental temperature can influence the development of some organisms.

Drugs can disrupt harmful cell differentiation.

(8)

• Injuries can affect gene expression.

• Viruses and bacteria can influence cell differentiation.

• Toxic chemicals can affect cell differentiation.

(9)

Adaptation is effective for some of the environmental influences
