Acta cir. bras; 38 (), 2023
Purpose: To evaluate inflammatory response in critical bone injuries after implantation of the biomaterial composed of hydroxyapatite (HA)/poly (lactic-coglycolic acid) (PLGA)/BLEED. Methods: Forty-eight male Wistar rats (280 ± 20 grams) were divided into two groups: control group (CG), in which the ani...

Adipose tissue-derived stem cells as a therapeutic strategy for enterocutaneous fistula: an experimental model study

Acta cir. bras; 38 (), 2023
Purpose: Enterocutaneous fistula (ECF) is a condition in which there is an abnormal connection between the intestinal tract and the skin. It can lead to high morbidity and mortality rates despite the availability of therapeutic options. Stem cells have emerged as a potential strategy to treat ECF. This s...
