In the sentence 'Here we examined the regulation of Semaphorin3G (Sema3G) in Human umbilical vein endothelial cells (HUVECs), and its potential role on endothelial cell in vitro', is the Prep 'on' right here after the word 'role'? If not, which one i have to choose?
Thank you in advance!
Great thanks to both of you!!
What i m currently thinking is what exactly 'in' or 'on' here means? To be honest, I can't see any differences between 'role in' and 'role on'.
Any particular advice for me to distinguish these two or it's just a fixed term i have to mechanically memorize?
Also, what's the difference between 'role in' and 'effect on' in this sentence?
