This study explores the efficacy of Autologous Micrografts Technology (AMG) in treating chronic wounds refractory to traditional therapies.
AMGs, derived from adipose tissue or dermis using a mechanical fragmentation process, were applied to patients with post-surgical dehiscence. A comprehensive evaluation of wound healing outcomes, including surface area reduction and complete healing, was conducted over a 90-day follow-up period. Additionally, the study investigated the cellular antioxidant activity of AMG solutions and characterized the exosomes obtained through mechanical disaggregation.
Results indicate significant improvements ( < 0.05) in wound healing, with 91.66% of patients showing at least a 50% reduction in lesion size and 75% achieving complete healing by day 90. Notably, AMG technology demonstrated immediate efficacy with fat-only application, while combined dermis and fat micrografts showed longer-term benefits, particularly in chronic wounds. The study also elucidated the mechanism of action of AMGs, highlighting their role in enhancing cellular antioxidant activity and exosome-mediated tissue regeneration.
Overall, these findings underscore the promising potential of AMG technology as a versatile and effective treatment option for chronic wounds, warranting further investigation into its mechanisms and clinical applications.
本研究探讨自体微移植技术(AMG)在治疗对传统疗法难治的慢性伤口方面的疗效。
使用机械破碎过程从脂肪组织或真皮中获取的AMG应用于手术切口裂开的患者。在90天的随访期内,对伤口愈合结果进行了全面评估,包括表面积减少和完全愈合情况。此外,该研究还调查了AMG溶液的细胞抗氧化活性,并对通过机械分解获得的外泌体进行了表征。
结果表明伤口愈合有显著改善(<0.05),91.66%的患者在第90天时病变大小至少减少50%,75%的患者实现完全愈合。值得注意的是,AMG技术在仅应用脂肪时显示出即时疗效,而真皮和脂肪微移植联合应用则显示出更长期的益处,特别是在慢性伤口中。该研究还阐明了AMG的作用机制,强调了它们在增强细胞抗氧化活性和外泌体介导的组织再生中的作用。
总体而言,这些发现强调了AMG技术作为慢性伤口通用且有效治疗选择的潜在前景,值得对其机制和临床应用进行进一步研究。
