To develop a closed, automated system that standardizes the processing of human adipose tissue to obtain and concentrate regenerative cells suitable for clinical treatment of thermal and radioactive burn wounds. A medical device was designed to automate processing of adipose tissue to obtain a clinical-grade cell output of stromal vascular cells that may be used immediately as a therapy for a number of conditions, including nonhealing wounds resulting from radiation damage. The Celution System reliably and reproducibly generated adipose-derived regenerative cells (ADRCs) from tissue collected manually and from three commercial power-assisted liposuction devices. The entire process of introducing tissue into the system, tissue washing and proteolytic digestion, isolation and concentration of the nonadipocyte nucleated cell fraction, and return to the patient as a wound therapeutic, can be achieved in approximately 1.5 h. An alternative approach that applies ultrasound energy in place of enzymatic digestion demonstrates extremely poor efficiency cell extraction. The Celution System is the first medical device validated and approved by multiple international regulatory authorities to generate autologous stromal vascular cells from adipose tissue that can be used in a real-time bedside manner. Initial preclinical and clinical studies using ADRCs obtained using the automated tissue processing Celution device described herein validate a safe and effective manner to obtain a promising novel cell-based treatment for wound healing.
开发一种封闭的自动化系统,该系统可标准化人类脂肪组织的处理过程,以获取并浓缩适合临床治疗热烧伤和放射性烧伤伤口的再生细胞。设计了一种医疗设备,用于自动处理脂肪组织,以获得临床级别的基质血管细胞输出,这些细胞可立即用作多种病症的治疗方法,包括辐射损伤导致的不愈合伤口。Celution系统能够可靠且可重复地从手动采集的组织以及三种商用动力辅助吸脂设备采集的组织中生成脂肪来源的再生细胞(ADRC)。将组织引入系统、组织清洗和蛋白水解消化、非脂肪细胞核细胞部分的分离和浓缩以及作为伤口治疗剂回输给患者的整个过程,大约可在1.5小时内完成。一种用超声能量代替酶消化的替代方法,其细胞提取效率极低。Celution系统是首个获得多个国际监管机构验证和批准的医疗设备,可从脂肪组织中生成自体基质血管细胞,并能以实时床边方式使用。使用本文所述的自动化组织处理Celution设备获得的ADRC进行的初步临床前和临床研究,验证了一种安全有效的方式,可获得一种有前景的新型基于细胞的伤口愈合治疗方法。
