Expression of apoptosis-related proteins before and after IITT+F treatment.
<p>Antibody array analysis of apoptosis-related proteins in ESCs of (A) untreated, non-differentiated (St-T1, red bar; KdS1, blue bar) and decidualized (dSt-T1, bright red bar; dKdS1, bright blue bar) ESCs, n = 4 ± SEM, *p<0.05 Sdc-1 wildtype vs. Sdc-1 kd cells, #p<0.05 non-differentiated vs. decidualized cells. (B) Antibody Array with protein from IITT+F treated, non-differentiated (St-T1, red bar; KdS1, blue bar) and decidualized (dSt-T1, bright red bar; dKdS1, bright blue bar) ESCs.

Quantification of active Caspase-3 in ESCs treated with embryonic stimuli.
<p>Non-differentiated (St-T1, red bar; KdS1, blue bar) and decidualized (dSt-T1, bright red bar; dKdS1, bright blue bar) ESCs were treated with IITT and F for 24h individually or in combination as indicated and the amount of active Caspase-3 was analyzed in ng/ml and displayed as mean±SEM of n = 3 independent experiments; *p<0.05 Sdc-1 wildtype vs. Sdc-1 kd cells, #p<0.05 non-differentiated vs. decidualized cells, ✝p<0.05 untreated controls vs. treated cells.</p

Loss of membrane asymmetry after IITT+F treatment.
<p>Non-differentiated (St-T1, KdS1) and decidualized (dSt-T1, dKdS1) ESCs were treatmed with IITT+F and loss of membrane asymmetry was visualized with Annexin V FITC staining (green), n = 3; (A)–(D) untreated controls: (A) St-T1, (B) KdS1, (C) dSt-T1, (D) dKdS1. (E)-(H) IITT+F treated: (E) St-T1, (F) KdS1, (G) dSt-T1, (H) dKdS1; blue nuclei are stained with Hoechst 33342. Scale bars indicate 100μm.</p
