hADSC-Exos improve proliferation rate and inhibit apoptosis rate in POI hGCs. a Schematic overview of hGC filter procedures. b hADSC-Exos improve proliferation in hGCs more significantly than using PBS. c hADSC-Exos inhibit apoptosis in hGCs more effectively than using PBS. Error bars indicate SD. ***p < 0.001 (compared with normal group). GC granulosa cell, POI premature ovarian insufficiency, hGC human granulosa cell, PBS phosphate buffered saline
