Figure 6From: Pancreatic-carcinoma-cell-derived pro-angiogenic factors can induce endothelial-cell differentiation of a subset of circulating CD34+ progenitorsDetection by immunohistochemistry of VE-cadherin and vWF in CD34+ cells cultured with or without PT45-CM. Cells were cultured for 19Â days under conditions supporting their differentiation toward myeloid lineage cells, in the presence or absence of PT45-CM. Specimens are representative examples of nine different experiments. Representative negative controls are also shown (original magnification 250X).Back to article page
