Specific Features of Juvenile Idiopathic Arthritis Patients' Chemokine Profile: The Data of Case-Control Study Analysis.

Background: Juvenile idiopathic arthritis pathogenesis involves a large number of different immune system cells, which are both sources and targets of chemokines, that affect not only their migration but also survival, proliferation, differentiation, production of all cytokine types, degranulation, and also directly stimulating or suppressing angiogenesis. Studyingthe contribution of chemokines to this disease pathogenesis will make it possible to identify new sensitive and specific markers for its diagnosis and subsequent dynamic monitoring of treatment effectiveness. The study aimed to identify a list of the most informative diagnostic markers from a wide range of juvenile idiopathic arthritis patients' blood plasma chemokines.

Dermal Fibroblasts as the Main Target for Skin Anti-Age Correction Using a Combination of Regenerative Medicine Methods.

This article includes the data from current studies regarding the pathophysiological mechanisms of skin aging and the regenerative processes occurring in the epidermis and dermis at the molecular and cellular level, mainly, the key role of dermal fibroblasts in skin regeneration. Analyzing these data, the authors proposed the concept of skin anti-age therapy that is based on the correction of age-related skin changes by stimulating regenerative processes at the molecular and cellular level. The main target of the skin anti-age therapy is dermal fibroblasts (DFs).

Commercial articulated collaborative 3D bioprinter for skin wound healing.

bioprinting is one of the most clinically relevant techniques in the emerging bioprinting technology because it could be performed directly on the human body in the operating room and it does not require bioreactors for post-printing tissue maturation. However, commercial bioprinters are still not available on the market. In this study, we demonstrated the benefit of the originally developed first commercial articulated collaborative bioprinter for the treatment of full-thickness wounds in rat and porcine models.
