Pulp tissue microenvironment

The pulp tissue microenvironment refers to the local milieu within the dental pulp, comprising a mix of resident cells (such as odontoblasts, fibroblasts, stem cells, and immune cells), insoluble extracellular matrix (ECM) components (collagens, non-collagenous proteins), soluble biochemical factors (growth factors, cytokines), vascular and nerve networks, and physical-chemical parameters. This environment orchestrates the behavior and fate of pulp cells, enabling homeostasis, tissue repair, regeneration, and immunological defenses. Its integrity is critical for dental pulp survival and responsiveness to injury or infection; alteration or destruction of this microenvironment impairs regeneration and can lead to inflammation or necrosis[1][3][5][8]. While often a target for strategies in tissue engineering and regenerative medicine—by recapitulating or modulating its components—it is not a classical therapeutic target (such as a receptor or single protein) but a complex biological system[1][3][5].
