1,25(OH)2D3 increase osteogenic potential of human periodontal ligament cells with low osteoblast potential.
Article in Journal of applied oral science : revista FOB, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivePeriodontal dental ligament mesenchymal stem cells (PDLMSCs) play a major role in periodontal tissue regeneration by the neoformation of root cementum and alveolar bone. These cells are highly heterogeneous, and many present low potential to renovate the hard tissue damaged by periodontal disease. A previous study found that the low osteoblast/cementoblast (O/C) differentiation potential of PDLMSCs is related to high asporin (ASPN) expression, which was identified as a negative regulator of PDL cells differentiation and mineralization, suppressing BMP-2-induced O/C differentiation. This study aimed to investigate whether 1,25(OH)2D3 treatment could stimulate the O/C differentiation of periodontal ligament mesenchymal progenitor cells characterized as low osteoblast potential (LOP), by asporin and bone morphogenetic protein-2 alteration. METHODOLOGY: Three LOP cell populations were cultured in standard medium (CONTROL), osteogenic medium (OM), and osteogenic medium associated with 1 nM of 1,25(OH)2D3 (OM + VD). The following assays were performed: 1) MTT to evaluate metabolic activity; 2) gene expression for asporin (ASPN), bone morphogenetic protein-2 (BMP-2), runt-related transcription factor 2 (RUNX2), alkaline phosphatase (ALP), osteocalcin (OCN), and vitamin D receptor (VDR) using qRT-PCR; 3) BMP-2 extracellular expression; and 4) quantification of mineralized nodule deposition by Alizarin Red Staining. Data were subjected to two-way ANOVA and Tukey's test (P<0.05).
resultsThe results showed that the 1,25(OH)2D3 treatment did not affect the cell viability, as demonstrated by metabolic activity increase over the 10 days in culture. After 14 days of 1,25(OH)2D3 treatment, the mRNA levels for ASPN and VDR decreased (P<0.05), while BMP-2 transcripts and extracellular expression increased (P<0.05). In parallel, RUNX2, ALP, and OCN gene expression was upregulated by 1,25(OH)2D3 treatment, resulting in an increase of mineral nodule deposition in vitro (P<0.05).
conclusionsThese data show that 1,25(OH)2D3 improves osteoblast/cementoblast differentiation of low osteoblast potential accompanied by alterations in ASPN and BMP-2 expression.
