Migration path of stem cells involved in the repair of damaged pancreatic tissue caused by pancreatitis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo investigate the migratory path of stem cells in pancreatic tissues damaged by pancreatitis and to preliminarily identify stem cells that efficiently contribute to the repair of damaged pancreatic tissues.
methodsAn animal model of acute pancreatitis was established, in which rats in the experimental group were given intraperitoneal (IP) injections of caerulein. Before the rats were sacrificed, 5-bromo-2'-deoxyuridine (BrdU) was administered by IP injection to label proliferating pancreatic cells. The localization and distribution of the stem cell-specific marker proteins nestin and c-kit in pancreatic tissues were examined using an immunohistochemical approach, and proliferation-specific BrdU incorporation was also analyzed.
results(1) The nestin-positive cells first appeared in the pancreatic interlobar vessels, and then, were observed in the pancreatic acinar and islet tissues. (2) C-kit-positive cells were located only in the pancreatic islets. (3) BrdU-positive cells first appeared in the area surrounding the interlobular region, and then were diffusely distributed and filled the pancreatic lobules.
conclusions(1) The stem cells, participated in the repair of damaged pancreatic tissue, appear firstly in the pancreatic interlobar vessels, then migrate toward the pancreatic lobules by using the interlobar vessels as channels and penetrate through the vascular endothelium into the pancreatic acinar tissues. A portion of the stem cells eventually penetrate into the islet tissue. (2) Exogenous stem cells, rather than the tissue-resident stem cells, efficiently contribute to the repair of damaged pancreatic tissues.
