Immunofluorescence staining of cleaved cytokeratin 18 (cl-Cyt 18) in placental explants exposed to hypoxia (A), cobalt chloride (B), or staurosporine (C), cultured with pomegranate juice compared with glucose, as control. Graphs on the far right summarize the syncytial morphology score (n = 4, *P < 0.05, Mann-Whitney rank test) or cl-Cyt 18 levels in pomegranate juice compared with glucose control (n = 12, *P < 0.05, Student's t-test).
