Background: Regenerative medicine holds promise for treating degenerative and inflammatory conditions like osteoarthritis (OA). However, the complex molecular mechanisms of OA and the limitations of current therapies remain challenges. Adipose-derived stem cells (ADSC) and stromal vascular fraction (SVF) are gaining attention for OA treatment due to their abundance in adipose tissue. The literature delineates two primary techniques for SVF extraction from adipose tissue: enzymatic digestion and mechanical methods. The Lipocube Hybrid SVF presents a straightforward and secure mechanical isolation method for SVF, enhancing its regenerative potential for various applications. Purpose: This study aims to provide valuable insights into the potential of Lipocube Hybrid SVF as a regenerative therapy for OA, contributing to the broader understanding of its applicability in addressing this debilitating condition. Method: To assess the effectiveness and safety of the Lipocube Hybrid SVF, we have designed a comparative study that evaluates cellular activity and viability, phenotypic characterization, and differentiation potential. The in vitro activity of mechanically isolated SVF is compared to the established gold standard enzymatic digestion method. After in vitro studies, Lipocube Hybrid mechanical isolation method was used to isolate SVF and applied in 42 knee and 7 hip joints of 28 patients with Grade II, Grade III, and Grade IV OA. Results: The Lipocube Hybrid group had slightly lower viable cell numbers but higher cell viability. Flow cytometry analysis showed the Lipocube Hybrid group exhibited more favorable markers for regenerative potential and reduced inflammatory response. Additionally, both groups demonstrated successful osteogenic differentiation, with the Lipocube Hybrid group excelling in chondrogenic and adipogenic differentiation. The clinical application of the Lipocube Hybrid SVF in OA patients resulted in significant improvements in WOMAC and VAS scores across different OA grades. Conclusions: This comparative study was conducted to evaluate the effectiveness and safety of the Lipocube Hybrid SVF, which has shown promise in laboratory settings, for different stages of osteoarthritis. The study findings provide valuable insights into the potential of Lipocube Hybrid SVF as a regenerative therapy for OA, highlighting its suitability for addressing this debilitating condition. 展开更多
