Figure 3From: Very small embryonic-like stem cells are involved in regeneration of mouse pancreas post-pancreatectomyImmunolocalization of OCT-4 in pancreas on day 5 post pancreatectomy. The cells in the lumen of blood vessels are positive for OCT-4 (A), (B), a specific marker for pluripotent stem cells. (C) Negative control. (D) These cells appear to extravasate from the blood vessels. (E), (F) OCT-4-positive cells are detected in between newly formed pancreatic lobes as well as below the coelomic epithelium. Few small cells with distinct nuclear OCT-4 are also visualized. Scale bar represents 20 μm.Back to article page
