I-Fibronectin yengane esanda kuzalwa (fFN)

Ukuzalwa ngaphambi kwesikhathi kubhekisela esifweni esibonakala ngokuphazamiseka kokukhulelwa ngemva kwamasonto angu-28 kuya kwangu-37 okukhulelwa. Ukuzalwa ngaphambi kwesikhathi kuyimbangela ehamba phambili yokufa nokukhubazeka ezinganeni eziningi ezingezona ezizalwa ngefa. Izimpawu zokuzalwa ngaphambi kwesikhathi zifaka phakathi ukufinyela kwesibeletho, izinguquko ekukhishweni koketshezi lwesitho sangasese sowesifazane, ukopha kwesitho sangasese sowesifazane, ubuhlungu emhlane, ukungakhululeki esiswini, umuzwa wokucindezelwa esinqeni kanye nokuqaqamba.

Njenge-isoform ye-fibronectin, i-Fetal Fibronectin (fFN) iyi-glycoprotein eyinkimbinkimbi enesisindo sama-molecule esingaba ngu-500KD. Kwabesifazane abakhulelwe abanezimpawu zokuzalwa ngaphambi kwesikhathi, uma i-fFN ingu-≥ 50 ng/mL phakathi kosuku olungu-0 lwamaviki angu-24 kanye nezinsuku ezingu-6 zamaviki angu-34, ingozi yokuzalwa ngaphambi kwesikhathi iyanda zingakapheli izinsuku ezingu-7 noma ezingu-14 (kusukela ngosuku lokuhlolwa kwesampula kusuka ekukhishweni kwesitho sangasese sowesifazane). Kwabesifazane abakhulelwe abangenazo izimpawu zokuzalwa ngaphambi kwesikhathi, uma i-fFN iphakanyisiwe phakathi kosuku olungu-0 lwamaviki angu-22 kanye nezinsuku ezingu-6 zamaviki angu-30, kuzoba nengozi eyengeziwe yokuzalwa ngaphambi kwesikhathi zingakapheli izinsuku ezingu-6 zamaviki angu-34.
