JEC cells were allocated into three categories: a control group, a 2D group, and a 3D group. Cultivation of JEC cells occurred with distinct media (supplemented with or without 2D/3D adipose-derived stem cell exosomes) per group. Endometrial cancer cell viability was evaluated by a Cell Counting Kit-8 (CCK-8) assay. Scratch assays gauged the migratory behavior of endometrial adenocarcinoma cells. A Transwell assay quantified cellular invasiveness.ResultsThe 3D group exhibited amplified cell proliferation (p < 0.05). Higher wound closure rates at 72 h were observed in the 3D group (p < 0.05). The Transwell assay demonstrated a substantial rise in the number of JEC cells traversing the Transwell chamber within the 3D group at 48 h (p < 0.05).ConclusionExosomes obtained from 2D and 3D adipose stem cells significantly bolstered cell proliferation, invasion, and migration. Exosomes sourced from 3D adipose-derived stem cells displayed greater efficacy than their 2D counterparts.
