Establishment of a porcine pancreatic stem cell line using T-REx(™) system-inducible Wnt3a expression.

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
objectivesPorcine pancreatic stem cells (PSCs) are highly valuable in transplantation applications for type II diabetes. However, there are still many problems to be solved before they can be used in the clinic, such as insufficient cell number availability and low secretion level of insulin. It has been reported that Wnt3a plays pivotal roles during cell proliferation and differentiation. Here, we have aimed to establish an ideal research platform using the T-REx(™) system, to study mechanisms of Wnt3a during PSC proliferation and differentiation. MATERIALS AND
methodsConstruction of the recombinant plasmid and cell transfection were used for establishment of a porcine PSC line. Related gene expressions were examined using quantitative real-time PCR (QRT-PCR), western blotting, immunostaining and flow cytometry. BrdU incorporation assay and cell cycle analysis were used to investigate Wnt3a roles in PSCs.
resultsWnt3a-expressing clones regulated by T-REx(™) were successfully obtained. Wnt3a and GFP expression were strictly regulated by Dox in a time- and dose-dependent manner. Furthermore, we found that Wnt3a-expressing porcine PSCs induced by Dox exhibited raised proliferative potential. After Dox stimulation, expression of PCNA, C-MYC and active β-catenin were higher, but were down-regulated after Dkk1 addition.
conclusionWe established a porcine PSC line that dynamically expressed Wnt3a, and we found that Wnt3a promoted PSC proliferative potential. This inducible expression system thus provides an important tool for further study on porcine PSC development and differentiation.
