Figure 1From: Differential expression of nitric oxide synthases in porcine aortic endothelial cells during LPS-induced apoptosisRepresentative images of pAEC morphology. A) pAECs under standard culture conditions. B, C, D) pAECs after 7, 15 and 24 h of LPS treatment, respectively (phase contrast microscope 200X). LPS treatment induced a moderate spindle-shape morphological change well evidenced after 24 h.Back to article page
