Cazotti Pereira, Bruno; Sacramento, Catharina Marques; Sallum, Enilson Antonio; Monteiro, Mabelle de Freitas; Casarin, Renato Corrêa Viana; Casati, Marcio Zaffalon; Silvério, Karina Gonzales, 2024, "1,25(OH)2D3 increases osteogenic potential of human periodontal ligament cells with low osteoblast potential", https://doi.org/10.48331/scielodata.EYNIXB, SciELO Data, V1
Periodontal dental ligament mesenchymal stem cells (PDLMSCs) play a major role in the regeneration of periodontal tissue through the neoformation of root cementum and alveolar bone. These cells are highly heterogeneous, and many present low potential to renovate the hard tissue d...

(A) Effect of 1,25(OH)2D3 on metabolic activity. Three LOP cell populations (LOP 1, LOP 2, and LOP 3) were cultured in standard medium (CONTROL), osteogenic medium (OM), and OM + 1nM of 1,25(OH)2D3 (OM + VD), and the MTT assay for assessing cell metabolism and viability was perfo...

Real-time PCR analysis indicated a downregulation of the mRNA levels for ASPN (A), and an increased level of transcripts for BMP-2 (B) after the treatment with 1nm of 1,25(OH)2D3. (C) Correlation between BMP-2 and ASPN on day 14. Experiments were performed in triplicate three tim...

Osteoblast genes expression after 1,25(OH)2D3 treatment. Real-time PCR analysis after treatment indicated that 1,25(OH)2D3 upregulated the expression of mRNAs for RUNX2 (A), ALP (B), and OCN (C). Bars represent mean ± standard deviation (SD) where intergroup analysis statistical...

BMP-2 protein expression. Quantification of BMP-2 secreted in supernatant of LOP 1, LOP 2 and LOP 3 cells after 3, 7 and 14 days of osteogenic induction associated with 1,25(OH)2D3. Bars represent mean ± standard deviation (SD) where intergroup analysis statistical differences ar...
