AB  - Background: Dental stem cells, which originate from the neural crest, due to their easy
accessibility might be good candidates in neuro-regenerative procedures, along with graphene-based
nanomaterials shown to promote neurogenesis in vitro. We aimed to explore the potential of liquid-
phase exfoliated graphene (LPEG) film to stimulate the neuro-differentiation of stem cells from apical
papilla (SCAP). Methods: The experimental procedure was structured as follows: (1) fabrication
of graphene film; (2) isolation, cultivation and SCAP stemness characterization by flowcytometry,
multilineage differentiation (osteo, chondro and adipo) and quantitative PCR (qPCR); (3) SCAP
neuro-induction by cultivation on polyethylene terephthalate (PET) coated with graphene film;
(4) evaluation of neural differentiation by means of several microscopy techniques (light, confocal,
atomic force and scanning electron microscopy), followed by neural marker gene expression analysis
using qPCR. Results: SCAP demonstrated exceptional stemness, as judged by mesenchymal markers’
expression (CD73, CD90 and CD105), and by multilineage differentiation capacity (osteo, chondro and
adipo-differentiation). Neuro-induction of SCAP grown on PET coated with graphene film resulted
in neuron-like cellular phenotype observed under different microscopes. This was corroborated
by the high gene expression of all examined key neuronal markers (Ngn2, NF-M, Nestin, MAP2,
MASH1). Conclusions: The ability of SCAPs to differentiate toward neural lineages was markedly
enhanced by graphene film.

AB  - Background The exact mechanisms of bone resorption in periodontitis have not been fully elucidated. The aims of this study were to analyze the expression of Notch signaling molecules, bone remodeling mediators, and pro-inflammatory cytokines in periodontitis patients and to determine their potential correlations. Methods The study included 130 individuals: 40 with aggressive periodontitis (AP group), 40 with chronic periodontitis (CP group), and 50 periodontally healthy controls. Total RNA was extracted from gingival crevicular fluid samples and relative gene expression of investigated molecules (Notch 1, Notch 2, Jagged 1, Hes 1, Hey 1, TNF-alpha, IL-17, RANKL, and OPG) was determined by reverse transcriptase - real-time polymerase chain reaction (RT-qPCR). Results In AP group, a significant increase of Notch 2, TNF-alpha, IL-17 and RANKL and a significant decrease of Notch 1 and Jagged 1 expression were observed compared to control group (P = 0.023, P = 0.005, P = 0.030, and P = 0.001 P = 0.031 and P = 0.029, respectively). Notch 2 and RANKL were also overexpressed in CP group compared to controls (P = 0.001 and P = 0.011). Significant correlations were observed in AP group between expression levels of the analyzed genes. Conclusion The present findings implicate Notch 2 overexpression in the ethiopathogenesis of bone resorption in aggressive and chronic periodontitis. The down-regulation of Notch 1 and Jagged 1 and loss of their osteoprotective function might cause a more excessive osteoclast formation and contribute to greater osteolysis in aggressive periodontitis.

AB  - Stem cell-based therapies are considered a promising treatment modality for many medical conditions. Several types of stem cells with variable differentiation potentials have been isolated from dental tissues, among them stem cells from apical papilla (SCAP). In parallel, new classes of biocompatible nanomaterials have also been developed, including graphene and carbon nanotube-based materials. The aim of the study was to assess whether graphene dispersion (GD) and water-soluble single walled carbon nanotubes (ws-SWCNT), may enhance SCAPs capacity to undergo neural differentiation. SCAPs cultivated in neuroinductive medium supplemented with GD and ws-SWCNT, separately and in combination, were subjected to neural marker analysis by real-time polymerase chain reaction (neurofilament medium [NF-M], neurogenin-2 [ngn-2], III-tubulin, microtubule-associated protein 2) and immunocytochemistry (NeuN and III-tubulin). GD, ws-SWCNT, and their combination, had neuro-stimulatory effects on SCAPs, as judged by the production of neural markers. Compared to cells grown in nanomaterial free medium, cells with GD showed higher production of B3T, cells with ws-SWCNT had higher production of ngn-2 and NF-M, while the combination of nanomaterials gave similar levels of both B3T and NF-M as the neuroinductive medium aloal ne, but with the finest neuron-like morphology. In conclusion, GD and ws-SWCNT seem to enhance neurdifferentiation of SCAP.
