Ngokusho kwemiphumela yocwaningo yezikhungo ezigunyaziwe zomhlaba wonke, izifo kanye nokuguga komzimba womuntu kuqala ekulimaleni kwamangqamuzana. Amandla amangqamuzana okuzivuselela azoncipha ngokwanda kokuguga. Lapho ukuguga namaseli agulayo eqhubeka nokuqongelela, amaseli amasha awakwazi ukuwathatha indawo ngesikhathi, futhi izifo kanye nokuguga kuyenzeka ngokungenakugwenywa.
Amaseli e-stem awuhlobo olukhethekile lweseli emzimbeni olungaphenduka noma yiluphi uhlobo lweseli emzimbeni wethu, olusetshenziselwa ukulungisa umonakalo nokufaka esikhundleni samaseli okuguga. Eminyakeni yamuva nje, ngokujula komqondo wokwelashwa kwamaseli e-stem wezifo kanye nomphumela wokulwa nokuguga, ukugcinwa kwamaseli e-stem sekuyinto ebalulekile empilweni yabantu abaningi yesikhathi esizayo.
Isikhathi Sokugcina Amaseli E-Stem ku-Liquid Nitrogen System
Ngokwethiyori, ukugcinwa kwe-nitrogen ewuketshezi kungagcina izinsiza zamaseli unomphela. Njengamanje, isampula yamaseli egcinwe isikhathi eside kunazo zonke elabhorethri ye-Chinese Academy of Sciences igcinwe iminyaka engama-70. Lokhu akusho ukuthi isitoreji esiqandisiwe singenziwa iminyaka engama-70 kuphela, kodwa intuthuko yalo lonke imboni inomlando weminyaka engama-70 kuphela. Ngokuthuthuka kwe-Times, isikhathi samaseli e-stem aqandisiwe sizoqhubeka nokwandiswa.
Yiqiniso, isikhathi sokugcinwa kwe-cryopreservation ekugcineni sincike ekushiseni kwe-cryopreservation, njengoba ukugcinwa kwe-cryopreservation okujulile kuphela okungenza amaseli alale. Ngaphansi kwezimo ezivamile, kungagcinwa amahora ama-5 ekushiseni kwegumbi. Izinga lokushisa eliphansi elingu-8 degrees Celsius lingagcinwa amahora angama-48. Iziqandisi ezijulile ezinokushisa okuphansi -80 degrees Celsius zingagcinwa inyanga yonke. I-nitrogen ewuketshezi ingunaphakade ngokombono ku--196 degrees Celsius.
Ngo-2011, imiphumela yokuhlolwa kwe-in vitro kanye nezilwane eyanyatheliswa encwadini ethi Blood nguSolwazi Broxmeyer kanye nethimba lakhe lase-Indiana University, okuyisazi ocwaningweni lwe-cord BLOOD stem cell biology, yafakazela ukuthi ama-stem cell agcinwe iminyaka engu-23.5 angagcina amandla awo okuqala okwanda kwe-in vitro, ukuhlukanisa, ukwanda kanye nokufakelwa kwe-in vivo.
Ngo-2018, iseli eliyinhloko eliqoqwe eBeijing Obstetrics and Gynecology Hospital laqandiswa iminyaka engama-20 nezinyanga ezi-4 ngoJuni 1998. Ngemva kokuvuselelwa, umsebenzi wawungu-99.75%!
Kuze kube manje, kunezindawo zokulondoloza igazi ezingaphezu kuka-300 emhlabeni, kanti amaphesenti angu-40 eYurophu, amaphesenti angu-30 eNyakatho Melika, amaphesenti angu-20 e-Asia kanye namaphesenti ayi-10 e-Oceania.
I-World Marrow Donor Association (WMDA) yasungulwa ngo-1994 futhi isekelwe eLeiden, eNetherlands. Enkulu kunazo zonke yiNational Marrow Donor Program (NMDP), eseMinneapolis, eMinn., futhi yasungulwa ngo-1986. I-DKMS inabanikeli abangaba yizigidi ezine, inikeza abangaphezu kuka-4,000 njalo ngonyaka. Uhlelo Lwabanikeli Be-Chinese Marrow (CMDP), olwasungulwa ngo-1992, luyibhange lesine ngobukhulu lomnkantsha ngemva kwe-United States, iJalimane neBrazil. Angahluka kwezinye izinhlobo zamaseli egazi, njengamaseli abomvu egazi, amaseli amhlophe egazi, ama-platelet njalo njalo.
Uhlelo lwe-Nitrogen oluyi-Liquid lokugcina amaseli e-Stem
Uhlelo lokugcina amaseli esiqu luqukethe ikakhulukazi ithangi elikhulu le-nitrogen cryogenic, isethi yesistimu yamapayipi e-vacuum jacketed (kufaka phakathi ipayipi le-vacuum jacketed, ipayipi le-vacuum jacketed, i-phase separator, i-vacuum jacketed stop valve, i-air-liquid barrier, njll.) kanye nesitsha sebhayoloji sokugcina amasampula eseli lesiqu ethangini.
I-nitrogen ewuketshezi inikeza isivikelo esiqhubekayo sokushisa okuphansi ezitsheni zezinto eziphilayo. Ngenxa yokwenziwa kwe-nitrogen ewuketshezi ibe yigesi yemvelo, ngokuvamile kuyadingeka ukugcwalisa izitsha zezinto eziphilayo kanye ngesonto ukuqinisekisa ukuthi izinga lokushisa esitsheni sezinto eziphilayo liphansi ngokwanele.
Imishini ye-HL Cryogenic
I-HL Cryogenic Equipment eyasungulwa ngo-1992 iwuphawu oluhambisana neChengdu Holy Cryogenic Equipment Company eShayina. I-HL Cryogenic Equipment izibophezele ekwakhiweni nasekukhiqizweni kwe-High Vacuum Insulated Cryogenic Piping System kanye ne-Support Equipment ehlobene nayo.
