Angiogenesis is a broad spread term of high interest in regenerative medicine and tissue engineering including the dental field. In the last two decades, researchers worldwide struggled to find the best ways to accelerate healing, stimulate soft, and hard tissue remodeling. Stem cells, growth factors, pathways, signals, receptors, genetics are just a few words that describe this area in medicine. Dental implants, bone and soft tissue regeneration using autologous grafts, or xenografts, allografts, their integration and acceptance rely on their material properties. However, the host response, through its vascularization, plays a significant role. The present paper aims to analyze and organize the latest information about the available dental stem cells, the types of growth factors with pro-angiogenic effect and the possible therapeutic effect of enhanced angiogenesis in regenerative dentistry.

Exosomal non-coding RNAs (ncRNAs), including miRNAs, lncRNAs, and circRNAs, have emerged as crucial modulators in cellular signaling, influencing wound healing processes. Stem cell-derived exosomes, which serve as vehicles for these ncRNAs, show remarkable therapeutic potential due to their ability to modulate wound healing stages, from initial inflammation to collagen formation. These ncRNAs act as molecular signals, regulating gene expression and protein synthesis necessary for cellular responses in healing.

The dehydrated human amnion-chorion membranes (dHACMs) derived from the human placenta have emerged as a promising biomaterial for dental pulp regeneration owing to their unique biological and structural properties. The purpose of this review is to explore the potentials of dHACMs in dental pulp tissue engineering, focusing on their ability to promote cellular proliferation, differentiation, angiogenesis, and neurogenesis. dHACMs are rich in extracellular matrix proteins and growth factors such as TGF-β1, FGF2, and VEGF.

Angiogenesis, the formation of new blood vessels, is a fundamental process in both physiological repair mechanisms and pathological conditions, including cancer and chronic inflammation. Hydrogels are commonly used as in vitro models to mimic the extracellular matrix (ECM) and support endothelial cell behavior during angiogenesis. Mesenchymal stem cells further augment cell and tissue growth and are therefore widely used in regenerative medicine.

Although hemostatic powders are commonly used in clinical and emergency settings, they frequently show poor absorption, raise cytotoxicity issues, and are not effective for fatal non-compressible bleeding. The purpose of this research is to create a self-gelling hemostatic powder based on chitosan, bentonite, and sodium polyacrylate (CBS) to improve the hemostatic effect. When liquid comes into contact with CBS powders, they can fuse and form a stable hydrogel in less than 30s.

Biomaterial-assisted therapeutic strategies enable precise modulation to direct endogenous cellular responses and harness regenerative capabilities for nerve repair. However, achieving effective cellular engagement during nerve remodeling remains challenging. Herein, a novel composite nerve guidance conduit (NGC), the GelMA/PLys@PDA-Fe@PLCL conduit is developed by combining aligned poly(l-lactide-co-caprolactone) (PLCL) nanofibers modified with polydopamine (PDA), ferrous iron (Fe⁺), and polylysine (PLys) with aligned methacrylate-anhydride gelatin (GelMA) hydrogel nanofibers.
