Transdifferentiation of periodontal ligament stem cells into acinar cells using an indirect co-culture system.
Article in Cell and tissue banking, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Serous Acinar Cells (ACs) are mature and functional secretory epithelial cells that develop and complete through other stem cells at the end of the ductal system. So, the regeneration of the salivary gland damaged by radiation does not occur without cell therapy. Todays, an accessible tissue like the Periodontal Ligament (PDL) of the tooth was considered to easily extract the Mesenchymal Stem Cells (MSCs). In-vitro differentiation of stem cells before transplantation to damaged tissue reduces the risk of tumorigenesis. This study was conducted to evaluate the feasibility of differentiation of PDLSCs into salivary acinar cells by a co-culture system. PDLSCs were isolated from adult human PDL tissue and co-cultured with rat parotid ACs using an indirect co-culture system. The transdifferentiation of PDLSCs was evaluated by PCR of Aquaporin 5 (AQP5) and Carbonic anhydrase 6 (CA6) genes, then quantitative real-time PCR was used to measure the gene expression levels. The data were analyzed by ANOVA. Specific bond with the correct size on 6% acrylamide gel and TBE5X buffer showed the expression of AQP5 and CA6 in PDLSCs co-cultured with acinar cells. RT-PCR revealed co-cultured PDLSCs with or without KGF (Keratinocyte Growth Factor) showed significantly increased expression of AQP5 genes in compared to the initial PDLSCs. Expression of AQP5 and CA6, indicating successful transdifferentiation of PDLSCs into ACs, in co-culture system for 3 weeks.
