Cell experiment:

Trophoblast cells are prepared from normal or GDM placentas. They are incubated in the presence of stimulants, insulin (100 nM) or both insulin and AGL-2263 (AGL, 5 μM) IR blocker, together for 24 hr[1].

AGL-2263 is an insulin receptor (IR) blocker.

AGL-2263 is an insulin receptor (IR) blocker[1].
