Q

How do you calculate the field size of a specimen

A

You take the field size and multiply it by how much width of the circle the specimen is taking up
Example 4000um x .75 = 3000 um

Q

What does it mean when it says stem cells are undifferentiated

A

It means they have not become any particular type of cell and can still become any type of cell.

Q

Every cell has identitical identity so why do different cells go to different tissues

A

They go to different tissues because different genes are “turned on” in different cell types to send it into different development paths.
