a small trendP =0.085
37 We observed a small trend towards an increase in platelet production with C3H/10T1/2, (1.92-fold change ±0.81 standard deviation [SD]; P =0.085) and a significant increase with both endothelial cell types; HUVEC (1.90-fold change ±0.60 SD; P <0.05) and HBMEC (1.73-fold change ±0.41 SD; P <0.05; Online Supplementary Figure S2A ) compared to the non-feeder control.
