Paper-based microfluidic systems have emerged as one of the most promising technologies for developing point-of-care diagnostic platforms (POCT) for detecting and monitoring various diseases. Saliva is a non-invasive biofluid easily collected, transported, and stored. Due to its accessibility and connection to systemic diseases, saliva is one of the best candidates for medical advancement at the point of care, where people can easily monitor their health.

Objective: To evaluate the healing response of critical defects in rat calvaria with recombinant cementum protein 1 (hrCEMP-1) combined with human dental pulp stem cells (hDPSC) and polylactide-co-glycolide/hydroxyapatite (PLGA/HA) scaffold.

Methods: The effect of hrCEMP-1 on proliferation and differentiation of human dental stem cells (hDPSCs) toward a mineralizing-like phenotype was evaluated in monolayer and PLGA/HA scaffold by qPCR. 5 mm calvarial defects were created in Wistar rats and filled with: 1) PLGA/HA scaffold; 2) hDPSCs-PLGA/HA scaffold; 3) hrCEMP-1-hDPSc-PLGA/HA scaffold; 4) control (without scaffold).

Unlabelled: Three-dimensional-porous scaffolds of bone graft substitutes play a critical role in both cell targeting and transplantation strategies. These scaffolds provide surfaces that facilitate the response of stem cells related to attachment, survival, migration, proliferation, and differentiation.

Objective: The aim of this study was to evaluate the behavior of human dental pulp mesenchymal stem cells cultured on scaffolds of polylactic/polyglycolic acid with and without hydroxyapatite.
