Kumelwe ukuba wezwa ngentambo yegazi, kodwa yini ngempela oyaziyo ngayo?
Igazi lentambo yigazi elihlala ku-placenta kanye nenkaba ngemva kokuzalwa kwengane yakho.Iqukethe amaseli we-hematopoietic stem cell (HSCs), iqembu lamaseli azivuselelayo futhi azihlukanisayo angakhula abe amaseli egazi ahlukahlukene avuthiwe.
Lapho igazi lentambo lidluliselwa ezigulini, amangqamuzana e-hematopoietic stem aqukethwe kuwo ahlukanisa abe amangqamuzana egazi amasha, anempilo futhi akhe kabusha isimiso se-hematopoietic sesiguli.Amaseli anjalo ayigugu e-hematopoietic stem, uma egcinwe kahle, angasetshenziswa ekwelapheni igazi elithile eliwuhlupho, izifo ezithinta umzimba nezicubu zomzimba, njenge-leukemia ne-lymphoma.
Abacwaningi baseMelika bamemezele ngo-Ephreli 15 ukuthi ososayensi babonakala belaphe ngempumelelo owesifazane wezinhlanga ezixubile ongenwe igciwane lesandulela ngculazi (human immunodeficiency virus) esebenzisa igazi lenkaba.Manje leli gciwane alikwazanga ukutholwa emzimbeni wowesifazane, okwaba yisiguli sesithathu nowesifazane wokuqala emhlabeni ukululama ku-HIV.
Kunezimo zomtholampilo ezingaba ngu-40,000 lapho igazi lezintambo lisetshenziswa emhlabeni jikelele.Lokhu kusho ukuthi i-cord blood ibilokhu idlulisela usizo emindenini eminingi.
Nokho, igazi lentambo alitholakali ukuze lisetshenziswe ngokushesha, futhi cishe lonke igazi lezintambo ligcinwa ezindaweni zokugcina igazi zezintambo emadolobheni amakhulu.Ingxenye enkulu yegazi ilahlekelwa umsebenzi wayo wasekuqaleni ngenxa yokugcinwa nokungcoliswa okungafanele futhi ngenxa yalokho iyalahlwa ngaphambi kokuba isetshenziselwe ukwelashwa.
Igazi le-umbilical cord lidinga ukugcinwa ku-nitrogen ewuketshezi ku--196 degrees Celsius ukuze kuqinisekiswe ukuthi ukusebenza kwamangqamuzana akuphazamiseki, futhi iseli lihlala lisebenza kahle lapho lisetshenziselwa izinjongo zokwelapha.Lokhu kusho ukuthi igazi lentambo kufanele ligcinwe emathangeni e-nitrogen ayiketshezi.
Ukuphepha kwethangi le-nitrogen eliwuketshezi kusemqoka ekusebenzeni kahle kwegazi lenkaba njengoba linquma ukuthi izinga lokushisa eliphansi -196 ℃ lingagcinwa yini.Uchungechunge lwe-Haier Biomedical Biobank luphephile ukugcina igazi lenkaba futhi luhlinzeka ngokuqhubekayo ngendawo ezinzile yokugcina amaseli e-hematopoietic stem.
I-Biobank Series Yesitoreji Esikhulu
Ukugcinwa kwayo kwesigaba se-vapor kuvimbela ukungcoliswa okuphambene, ukuvikela ukusebenza kahle nokuphepha kwegazi lentambo;ukufana kwayo okuhle kakhulu kwezinga lokushisa kunikeza indawo yokugcina ezinzile ezingeni lokushisa elingu -196 °C.Umsebenzi wayo wokuvikela ukuchaphaza unikeza isiqinisekiso esiphephile senqubo yokusebenza, ngaleyo ndlela iqinisekisa ngokugcwele ukuphepha nokusebenza kahle kwegazi lenkaba.
Njengoba amathangi e-nitrogen ewuketshezi esetshenziswa emikhakheni eyengeziwe, i-Haier Biomedical yethule isisombululo sokugcina ithangi le-nitrogen eliwuketshezi elinesitobhi esisodwa nevolumu egcwele yazo zonke izimo.Amathangi e-nitrogen e-liquid ahlukene afaniswa nezimo ezahlukahlukene ngokuya ngezidingo zakho, ngaleyo ndlela onge isikhathi esengeziwe futhi anikeze lula kakhulu.
