Alkaline phosphatase (ALP) activity. ALP activity measured in nmol P-nitrophenol phosphate (pNNP)/ml h-1 mono-/co-cultures supplemented with and without vascular endothelial growth factor (VEGF) (100 ng/ml). Assays from three separate patient samples. a Basal diaphyseal/human umbilical vein endothelial cell (HUVEC) mono-/co-cultures; b diaphyseal/HUVEC mono-/co-cultures supplemented with VEGF; c basal epiphyseal/HUVEC mono-/co-cultures; d epiphyseal/HUVEC mono-/co-cultures supplemented with VEGF. Results are expressed as mean ± SD: *p <0.05, **p <0.01, ***p <0.001. CoD diaphyseal co-culture, CoE epiphyseal co-culture
