Commercial preparations of human "Lyodura soft" were implanted into the subcutaneous connective tissue of 40 Wistar rats. After survival times from 7 days up to 1 year the samples were examined by light microscopy. An initial reaction of mononuclear cells, activated fibroblasts, and some giant cells of foreign body type in the surrounding connective tissue is followed by the development of a fibrous capsule rarefied by cells around the implant in the time up to 3 months. After 6 months and more clearly after one year the capsule is reduced or even completely vanished. The implant remains then integrated in the subcutaneous connective tissue almost without residual reactions or signs of resorption.

Hypertrophic scar (HS) is a common fibroproliferative disorders with no fully effective treatments. The conversion of fibroblasts to myofibroblasts is known to play a critical role in HS formation, making it essential to identify molecules that promote myofibroblast dedifferentiation and to elucidate their underlying mechanisms. In this study, we used comparative transcriptomics and single-cell sequencing to identify key molecules and pathways that mediate fibrosis and myofibroblast transdifferentiation.

The deltoid ligament (medial collateral ligament) and the syndesmosis (a composite ligamentous structure at the distal tibiofibular junction) are critical for maintaining ankle stability. In cases of high-energy ankle fractures, these structures are often injured simultaneously, leading to instability and potential long-term complications such as post-traumatic arthritis. This review aims to explore advancements in minimally invasive techniques for the treatment of combined deltoid ligament and syndesmosis injuries, with a focus on optimizing surgical outcomes and reducing patient morbidity.

Background: The excessive use of antibiotics is a major contributor to the global issue of antimicrobial resistance (AMR), a significant threat to human and animal health. Hence, assessing new strategies for managing Multi-Drug Resistant (MDR) microorganisms is vital. In this study, the use of mechanically isolated mature adipose cells (MIMACs) and their lysate (Adipolysate) as a new sustainable antimicrobial agent was assessed against Methicillin-resistant Staphylococcus aureus (MRSA).

Difficult-to-heal wounds management accounts for about 4% of healthcare costs, highlighting the need for innovative solutions. Extracellular signals drive cell proliferation during tissue regeneration, while epigenetic mechanisms regulate stem cell homeostasis, differentiation, and skin repair. Exploring epigenetic regulation in adipose-derived stem cells (ADSCs) holds promise for improving skin injury treatments.

Introduction: The infrapatellar fat pad and synovium are the sites of immune cell infiltration and the origin of proinflammation. Studies have shown that Hoffa's synovitis may be a sign of early-stage osteoarthritis (OA). However, there have been no effective interventions specifically for Hoffa's synovitis.
