Cell-Assisted Lipotransfer
يعرف أيضا باسم: نقل الدهون بمساعدة الخلايا, سيل اسيستد ليبوترانسفر, CAL
Cell-assisted lipotransfer (CAL) is a specific fat grafting protocol in which stromal vascular fraction isolated from one portion of the harvested fat is added to the remaining fat before injection.
세포보조 지방이식(CAL)이란 무엇인가요?
세포보조 지방이식(CAL)은 흡입한 지방의 일부에서 기질혈관분획(SVF)을 분리한 뒤, 처리하지 않은 나머지 지방에 섞어 이식하는 술기입니다. 목적은 이식한 지방의 생착률을 높이는 것입니다. 배양해 증식시킨 줄기세포를 투여하는 치료가 아닙니다. SVF는 지방유래 줄기세포를 포함하되 혈관내피세포·혈액세포 등이 함께 섞인 집단입니다.
نظرة عامة
CAL was described by Yoshimura and colleagues in 2008. Part of the lipoaspirate is processed to isolate the stromal vascular fraction, which is then combined with the untreated portion of the fat before grafting, with the stated aim of improving graft retention. CAL is one defined protocol within the broader category of SVF-assisted fat grafting; the two terms are related but not interchangeable, because SVF-assisted grafting also covers protocols that differ in cell dose, isolation method and the ratio of processed to untreated fat. Reported retention varies across studies, and isolation method and cell dose are not standardised between centres.
