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  - Aim To characterize stem cells originating from different dental tissues (apical papilla [SCAP], dental follicle [DFSC], and pulp [DPSC]) and test the capacity of Raman microspectroscopy to distinguish between the three dental stem cell types. Methods SCAR DFSC, and DPSC cultures were generated from three immature wisdom teeth originating from three patients. Cell stemness was confirmed by inducing neuro-, osteo-, chondro-, and adipo-differentiaton and by mesenchymal marker expression analysis by flow-cytometry and real-time polymerase chain reaction. Cellular components were then evaluated by Raman microspectroscopy. Results We found differences between SCAP, DFSC, and DPSC Raman spectra. The ratio between proteins and nucleic acids (748/770), a parameter for discriminating more differentiated from less differentiated cells, showed significant differences between the three cell types. All cells also displayed a fingerprint region in the 600-700 cm(-1) range, and characteristic lipid peaks at positions 1440 cm(-1) and 1650 cm(-1). Conclusion Although different dental stem cells exhibited similar Raman spectra, the method enabled us to make subtle distinction between them.

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.
