Umele ukuba uvile ngegazi lentambo, kodwa yintoni ngokwenene oyaziyo ngalo?
Igazi lentambo ligazi elihlala kwi-placenta nakwi-umbilical cord emva kokuzalwa komntwana wakho. Liqulathe ezinye ii-hematopoietic stem cells (HSCs), iqela leeseli ezizihlaziyayo nezizahlulayo ezinokukhula zibe ziiseli zegazi ezahlukeneyo ezivuthiweyo.
Xa igazi lentambo lifakwa kwizigulana, iiseli ze-hematopoietic ezikuyo ziyahluka zibe ziiseli zegazi ezintsha neziphilileyo kwaye zakha kwakhona inkqubo ye-hematopoietic yesigulana. Ezi seli ze-hematopoietic ezixabisekileyo, ukuba zigcinwe kakuhle, zinokusetyenziselwa ukunyanga ezinye izifo ezibangela iingxaki egazini, i-metabolic kunye ne-immune, ezifana ne-leukemia kunye ne-lymphoma.
Abaphandi baseMelika babhengeze ngo-Epreli 15 ukuba izazinzulu zibonakala ngathi zimphilisile ngempumelelo umfazi weentlanga ezahlukeneyo osulelwe yi-HIV esebenzisa igazi le-umbilical cord. Ngoku le ntsholongwane ayikwazanga ukubonwa emzimbeni walo mfazi, owathi ngaloo ndlela waba sisigulana sesithathu nesokuqala emhlabeni ukuba aphile kwi-HIV.
Kukho amatyala ezonyango amalunga nama-40,000 apho kusetyenziswa igazi lentambo kwihlabathi liphela. Oku kuthetha ukuba igazi lentambo liye lanceda iintsapho ezininzi.
Nangona kunjalo, igazi lentambo alifumaneki ukuze lisetyenziswe ngoko nangoko, kwaye phantse lonke igazi lentambo ligcinwa kwiibhanki zegazi lentambo kwizixeko ezikhulu. Inxalenye enkulu yegazi ilahlekelwa ngumsebenzi wayo wokuqala ngenxa yokugcinwa okungafanelekanga kunye nokungcola kwaye ngenxa yoko ilahlwa ngaphambi kokuba isetyenziswe kunyango.
Igazi le-umbilical cord kufuneka ligcinwe kwi-nitrogen engamanzi kwi--196 degrees Celsius ukuqinisekisa ukuba umsebenzi weseli awuphazamiseki, kwaye ngaloo ndlela iseli ihlala isebenza xa isetyenziselwa iinjongo zonyango. Oku kuthetha ukuba igazi le-cord kufuneka ligcinwe kwiitanki ze-nitrogen engamanzi.
Ukhuseleko lwetanki ye-nitrogen engamanzi lubalulekile ekusebenzeni kwegazi le-umbilical cord njengoko lugqiba ukuba ingaba indawo enobushushu obuphantsi obuyi-196 ℃ inokugcinwa na. Uthotho lwe-Haier Biomedical Biobank lukhuselekile ukugcina igazi le-umbilical cord kwaye luhlala lubonelela ngendawo ezinzileyo yokugcina iiseli ze-hematopoietic stem.
Uthotho lweBiobank lokugcina izinto ezinkulu
Indawo yokugcina yayo yomphunga ithintela ukungcoliswa okunqamlezileyo, ikhusela ukusebenza kakuhle kunye nokhuseleko lwegazi lentambo; ukufana kwayo okuhle kakhulu kubushushu kubonelela ngendawo yokugcina ezinzileyo kubushushu obuyi--196 °C. Umsebenzi wayo wokumelana nokutshiza unika isiqinisekiso esikhuselekileyo senkqubo yokusebenza, ngaloo ndlela iqinisekisa ngokupheleleyo ukhuseleko kunye nokusebenza kakuhle kwegazi lentambo yesisu.
Njengoko iitanki ze-nitrogen ezingamanzi zisetyenziswa kwiindawo ezininzi, iHaier Biomedical iqalise isisombululo sokugcina itanki ye-nitrogen engamanzi esinendawo enye nesipheleleyo kuzo zonke iimeko. Iitanki ze-nitrogen ezingamanzi ezahlukeneyo zihambelana neemeko ezahlukeneyo ngokweemfuno zakho, ngaloo ndlela zigcina ixesha elingakumbi kwaye zibonelela ngokulula ngakumbi.
