Oral Mucosa Remodeling Induced by Injecting New Cellular Treatment Factor (NCTF) and Human-derived Exosomes (ASCE & CellExosome).

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
Background: Exosomes mediate tissue regeneration by promoting angiogenesis, fibroblast activity, and extracellular matrix remodeling. New Cellular Treatment Factor (NCTF), cellular treatment factor solutions containing amino acids, vitamins, nucleotides, coenzymes, minerals, and hyaluronic acid, are used in regenerative medicine, but their combined effects with human-derived exosomes on the oral mucosa remain unclear. The aim of this study was to evaluate the histological and immunohistochemical changes in normal hamster oral mucosa following treatment with an NCTF solution enriched with 2 distinct human exosome formulations at different time points. Methods: Sixty-three male hamsters were randomized into 3 groups: saline-injected control, NCTF with cell-derived exosomes (CellExosome), and NCTF solution with adipose stem cell-derived exosomes (ASCEs). Injections were administered into the buccal mucosa, and tissues were harvested at baseline, day 3, and day 7. Hematoxylin-eosin, Masson trichrome, and Van Gieson staining were used to assess mucosal structure and collagen remodeling, whereas angiogenesis was quantified using CD34 immunohistochemistry. Results: Both exosome-treated groups demonstrated progressive increases in fibroblast proliferation, collagen organization, and microvessel density from day 3 to day 7 compared with controls. The NCTF + CellExosome group consistently exhibited the most pronounced effects, with significantly greater angiogenesis and extracellular matrix remodeling across all time points ( Conclusions: In a hamster model, exosome-enriched biorevitalization solutions enhanced angiogenesis and collagen remodeling in normal oral mucosa in a time-dependent manner. The NCTF + CellExosome formulation demonstrated superior regenerative potential, supporting its potential translational relevance for future regenerative and aesthetic research.
