Lecture two

Question 1

what do all developmental processes depend on

Answer 1

the functions and properties of cells and the ways cells interact

Question 2

name the mechanisms of development

Answer 2

cell devision vs cell death
stem/progenitor cells
asymmetric cell division 
lateral inhibiton
morphogens and gradients
master regulatory genes
branching
cell migrstion
tissue morphogensis

Question 3

hpw does cell div and cell death influence developmeent

Answer 3

determines number
proliferration growth
remove unwanted cells

Question 4

how do stem cells and asummetiric divsion influence development

Answer 4

splitting fate]balancing growth and renewal vs differenetiation

Question 5

how does lateral inhibtion influence development

Answer 5

differences within a tissue

tissue patterning

Question 6

how do gradients and morphogens influence development

Answer 6

organise at a large scale

pattern

Question 7

how do master regulatory genes influence devleopment

Answer 7

switch on off new identities

Question 8

how does cell migration influence development`

Answer 8

increase cell diverstiy

distribute cells from same source into different region and vice versa
