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.","official_url":null,"image_url":null,"country":null,"region":null,"wikidata_id":null,"wikipedia_url":null,"verified":false,"scores":{"authority":0,"trust":0,"citation":0},"topic":{"slug":"fat-grafting","name":"Autologous Fat Grafting"},"url":"https://worldwiki.io/entity/cell-assisted-lipotransfer","facts":[],"relations":[{"type":"uses","confidence":100,"target":{"id":13,"slug":"stromal-vascular-fraction","name":"Stromal Vascular Fraction","type":"medical","description":"The stromal vascular fraction (SVF) is a heterogeneous mix of cells obtained from adipose tissue after removing mature fat cells; it contains stromal/stem cells, endothelial cells, pericytes and immune cells.","url":"https://worldwiki.io/entity/stromal-vascular-fraction"}},{"type":"related_to","confidence":100,"target":{"id":16,"slug":"fat-graft-survival","name":"Fat Graft Survival","type":"concept","description":"Fat graft survival (retention) is the share of transferred fat volume that remains after healing; part of every fat graft is resorbed, and reported retention varies widely by technique, site and how it is measured.","url":"https://worldwiki.io/entity/fat-graft-survival"}},{"type":"is_a","confidence":100,"target":{"id":23,"slug":"svf-assisted-fat-grafting","name":"SVF-assisted Fat Grafting","type":"medical","description":"SVF-assisted fat grafting (a form of cell-assisted lipotransfer) enriches the fat graft with stromal vascular fraction isolated from part of the harvested fat, with the aim of improving graft survival.","url":"https://worldwiki.io/entity/svf-assisted-fat-grafting"}}],"questions":[{"slug":"세포보조-지방이식-cal-이란-무엇인가요","question":"세포보조 지방이식(CAL)이란 무엇인가요?","intent":"informational","language":"ko","short_answer":"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.
