Kumelwe ukuba uke wezwa ngegazi lentambo, kodwa yini ngempela oyaziyo ngalo?
Igazi lentambo yigazi elihlala ku-placenta kanye nentambo yesisu ngemva kokuzalwa komntwana wakho. Liqukethe amanye amaseli e-hematopoietic stem (ama-HSC), iqembu lamaseli azivuselelayo futhi azihlukanisayo angakhula abe amaseli egazi ahlukahlukene avuthiwe.
Uma igazi lentambo lifakwa ezigulini, amaseli okuqala egazi aqukethwe kuwo ayahluka abe amaseli egazi amasha, anempilo futhi akhe kabusha uhlelo lwegazi lwesiguli. Amaseli okuqala egazi ayigugu kangaka, uma egcinwe kahle, angasetshenziswa ukwelapha ezinye izifo ezikhathazayo zegazi, i-metabolic kanye ne-immune, njenge-leukemia kanye ne-lymphoma.
Abacwaningi base-US bamemezele ngo-Ephreli 15 ukuthi ososayensi babonakala sengathi baphulukise ngempumelelo owesifazane wohlanga oluxubile onegciwane lesandulela ngculazi (i-HIV) esebenzisa igazi le-umbilical cord. Manje leli gciwane alikwazanga ukutholakala emzimbeni wowesifazane, oye waba yisiguli sesithathu nowesifazane wokuqala emhlabeni ukululama kwi-HIV.
Kunezimo zezokwelapha ezingaba ngu-40,000 lapho kusetshenziswa khona igazi lentambo emhlabeni jikelele. Lokhu kusho ukuthi igazi lentambo belilokhu lisiza imindeni eminingi.
Kodwa-ke, igazi lentambo alitholakali ukuze lisetshenziswe ngokushesha, futhi cishe lonke igazi lentambo ligcinwa emabhange egazi lentambo emadolobheni amakhulu. Ingxenye enkulu yegazi ilahlekelwa umsebenzi wayo wokuqala ngenxa yokugcinwa okungafanele kanye nokungcola ngakho-ke ilahlwa ngaphambi kokuba isetshenziselwe ukwelashwa.
Igazi lentambo yomhlathi lidinga ukugcinwa ku-nitrogen ewuketshezi ku--196 degrees Celsius ukuqinisekisa ukuthi umsebenzi weseli awuphazamiseki, futhi ngaleyo ndlela iseli lihlala lisebenza kahle uma lisetshenziselwa izinjongo zokwelapha. Lokhu kusho ukuthi igazi lentambo kufanele ligcinwe emathangini e-nitrogen ewuketshezi.
Ukuphepha kwethangi le-nitrogen eliwuketshezi kubalulekile ekusebenzeni kahle kwegazi le-umbilical cord njengoba kunquma ukuthi indawo yokushisa ephansi engu--196 ℃ ingagcinwa yini. Uchungechunge lwe-Haier Biomedical Biobank luphephile ukugcina igazi le-umbilical cord futhi luhlinzeka njalo ngendawo ezinzile yokugcina amaseli e-hematopoietic stem.
Uchungechunge lwe-Biobank Lokugcina Isitoreji Esibanzi
Isitoreji sayo sesigaba somusi sivimbela ukungcoliswa okuphambene, sivikele ukusebenza kahle nokuphepha kwegazi lentambo; ukufana kwayo okuhle kakhulu kwezinga lokushisa kunikeza indawo yokugcina ezinzile ekushiseni okungu--196 °C. Umsebenzi wayo wokumelana nokuchaphaza unikeza isiqinisekiso esiphephile senqubo yokusebenza, ngaleyo ndlela kuqinisekiswe ngokuphelele ukuphepha nokusebenza kahle kwegazi lentambo yenkaba.
Njengoba amathangi e-nitrogen ewuketshezi esetshenziswa emikhakheni eminingi, i-Haier Biomedical yethule ikhambi lokugcina ithangi le-nitrogen eliwuketshezi elinendawo eyodwa futhi eligcwele lazo zonke izimo. Amathangi e-nitrogen ewuketshezi ahlukene ahambisana nezimo ezahlukene ngokwezidingo zakho, ngaleyo ndlela onge isikhathi esiningi futhi anikeze ukulula okwengeziwe.
