Poisk optimal'nykh kletochnykh modeley dlya izucheniya patogeneza giperplasticheskikh rubtsov yavlyayetsya aktual'noy zadachey. Tsel'yu issledovaniya bylo otsenit' perspektivu ispol'zovaniya telomerizovannykh fibroblastov v kachestve ob"yekta pri 3D-modelirovanii patologicheskikh gipertroficheskikh rubtsov in vitro. Kletki NF i Fb-hTERT kul'tivirovali v vide monosloya i sferoidov, v intaktnom sostoyanii i pri vozdeystvii TGFb1. Metabolicheskuyu aktivnost' kletok otsenivali metodom MTT. Skorost' zarastaniya defekta monosloya kletok vychislyali s pomoshch'yu scratch-testa. Uroven' ekspressii genov, assotsiirovannykh s giperplasticheskimi protsessami, opredelyali metodom qRT-PCR. Dlya Fb-hTERT kharakterno boleye vyrazhennoye po sravneniyu s NF usileniye metabolicheskoy aktivnosti kletok pri vozdeystvii TGFb1 (dlya 1 ng/ml 179 ± 12% i 135 ± 13% sootvetstvenno; p < 0,05). Sferoidy, sformirovannyye iz Fb-hTERT, byli znachitel'no krupneye sferoidov, poluchennykh iz NF. Produktsiya osnovnykh spetsifichnykh dlya fibroblastov belkov, assotsiirovannykh s produktsiyey vnekletochnogo matriksa (COL1A1, COL3A1, FN1), pri stimulyatsii TGFb1 byla nizhe v Fb-hTERT po sravneniyu s NF (boleye chem v 25, 20 i 2 raza sootvetstvenno; p < 0,05). Intaktnyye NF boleye aktivno, po sravneniyu s Fb-hTERT, vosstanavlivali defekt monosloya (v 2,28 raza na vtoryye sutki; p < 0,05). Pri etom vozdeystviye TGFb1 privodilo k uvelicheniyu skorosti zapolneniya defekta kletkami Fb-hTERT (v 2 raza na vtoryye sutki; p < 0,05), no ne NF. Takim obrazom, telomerizovannyye fibroblasty imeyut ryad fenotipicheskikh priznakov, kharakternykh dlya keloidnykh fibroblastov, no v to zhe vremya yest' ogranicheniya, kotoryye sleduyet uchityvat' pri ispol'zovanii Fb-hTERT dlya modelirovaniya patologicheskikh gipertroficheskikh rubtsov.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
