Decellularization of Rat Submandibular Gland for Salivary Gland Tissue-Engineering Applications.

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
objectivesThis study describes a robust and versatile method for decellularization of rat submandibular glands (SMGs).
methodsBriefly, rat SMGs were harvested and subjected to perfusion cycles using an anionic detergent. Native and decellularized SMG tissues were subjected to histological analysis using hematoxylin and eosin (H&E) stain and immunohistochemical staining using Hoescht reagent. Further, complementary DNA was synthesized using the native and decellularized SMG tissues and subjected to quantitative reverse transcription polymerase chain reaction (RT-PCR) using rat-specific genes (i.e., α-amylase [Amyl], aquaporin 5 [Aqp5], mucin 19 [Muc19] and glyceraldehyde-3-phosphate dehydrogenase [GAPDH]). The total DNA within native and decellularized SMG tissues were also quantified.
resultsH&E staining of SMG tissues revealed preserved ECM content. Decellularized SMG scaffolds lacked cellular material but retained collagen bundles similar to native SMGs. Hoechst reagent immunostaining showed cell nuclei and DNA present in native SMG but not in decellularized SMG scaffolds. Quantitative RT-PCR analysis showed specific amplification products of salivary gland-specific genes (Amyl, Muc19 and Aqp5) and GAPDH in the native SMG tissues. However, no amplification product was observed in the cDNAs from the decellularized SMG scaffolds, confirming the absence of DNA. Quantification of the DNA content showed that the decellularized SMG scaffolds had significantly lower DNA content than native SMG tissue.
conclusionsResults from this study demonstrated that the decellularization protocol was effective in removing cellular material while preserving the extracellular matrix components and structural integrity of the native SMG tissue.
