Figure 3From: Pancreatic-carcinoma-cell-derived pro-angiogenic factors can induce endothelial-cell differentiation of a subset of circulating CD34+ progenitorsAltered morphology during differentiation of CD34+cells in the presence of PT45-CM. Circulating CD34+ cells were cultured for 19Â days in the presence of GM-CSF, IL-3 and SCF, either in the absence or in the presence of PT45-CM. Shown are representative examples of cells cultured in GM-CSF, IL-3 and SCF alone (A); as panel A, but including PT45-CM (B).Back to article page
