Laminins are the one of the most important protein families e.g. laminins regulate differentiation and tissue integrity.
‘e.g.’ (exempli gratia = for example) is not the same as ‘i.e.’ (id est = that is)
The phrasing above implies that there are more behaviours that can be regulated by laminins therefore the list are examples. In contrast, the second clause of the collagen phrase is an explanation of the first therefore i.e. is appropriate.
Here is the same core content about laminins but written as i.e.
Laminins are the one of the most important protein families i.e. they regulate differentiation, migration, adhesion, proliferation and tissue integrity. I did mention that laminins are awesome!
