Fig. 2From: VEGF vascularization pathway in human intervertebral disc does not change during the disc degeneration processUnchanged VEGF pathways in IVD. a Schematic representation of members of the classic VEGF vascularization signalling pathway. b Microarray meta-analysis of 14 expression profiles remained unchanged through the degeneration grades (n = 26), except for vascular endothelial growth factor A (VEGFA). Axes of x indicate state of degeneration according to Thompson grading system, axes of y indicate average expression levels in log2. Results are based on VSN normalizationBack to article page
