The Canadian group plans to use the unique abilities of the co-culture-compatible E-Plate Insert and xCELLigence cell response monitoring technology, to determine the effect of co-culture on primary villous
trophoblast homeostasis (polarization, differentiation/syncytialization, fusion, apoptosis) and on H295R cells (proliferation, viability, apoptosis) as well as expression and activity levels of key placental and fetal adrenal steroidogenic enzymes.
