Ngokwemiphumela yocwaningo yezikhungo ezigunyazwe ngamazwe ngamazwe, izifo kanye nokulula komzimba womuntu kuqala ekulimaleni kwamangqamuzana. Ikhono lamaseli lokuzivuselela lizokwehla ngokukhula kweminyaka. Lapho amangqamuzana aguga nagulayo eqhubeka nokunqwabelana, amangqamuzana amasha awakwazi ukuwashintsha ngesikhathi, futhi izifo nokululazeka kwenzeka ngokungenakugwenywa.
Ama-stem cells awuhlobo olukhethekile lwengqamuzana emzimbeni olungashintsha lube yinoma yiluphi uhlobo lwengqamuzana emzimbeni wethu, olusetshenziselwa ukulungisa umonakalo nokushintsha amaseli agugile. Eminyakeni yamuva nje, ngokujula komqondo wokwelashwa kwe-stem cell kwezifo kanye nomphumela wokulwa nokuguga, i-stem cell cryopreservation isibe yisinqumo esibalulekile empilweni yesikhathi esizayo yabantu abaningi.
Isikhathi Sokugcina Samaseli E-Stem Ohlelweni Lwe-Nitrogen Ewuketshezi
Ngokwethiyori, i-liquid nitrogen cryopreservation ingagcina izinsiza zamaseli unomphela. Njengamanje, isampula leseli elaziwa isikhathi eside kunawo wonke elalondolozwa elabhorethri ye-Chinese Academy of Sciences ligcinwe iminyaka engu-70. Lokhu akusho ukuthi isitoreji esiqandisiwe singenziwa kuphela iminyaka engu-70, kodwa ukuthuthukiswa kwemboni yonke kunomlando weminyaka engu-70 kuphela. Ngokuthuthukiswa kwe-Times, isikhathi samaseli esiqu esiqandisiwe sizonwetshwa ngokuqhubekayo.
Yiqiniso, ubude be-cryopreservation ekugcineni buxhomeke ekushiseni kwe-cryopreservation, njengoba i-cryopreservation ejulile kuphela engenza amaseli alale. Ngaphansi kwezimo ezijwayelekile, ingagcinwa amahora angu-5 ekamelweni lokushisa. Izinga lokushisa eliphansi elingu-8 degrees Celsius lingagcinwa amahora angama-48. Iziqandisi ezijulile zokushisa okuphansi -80 degrees Celsius zingagcinwa inyanga yonke. I-nitrogen ewuketshezi ngokwethiyori ingunaphakade ku- -196 degrees Celsius.
Ngo-2011, imiphumela yokuhlolwa kwe-in vitro nezilwane eyanyatheliswa encwadini ethi Igazi nguSolwazi u-Broxmeyer nethimba lakhe lase-Indiana University, onguchwepheshe ocwaningweni lwe-cord BLOOD stem cell biology, yafakazela ukuthi ama-stem cells agcinwe iminyaka engu-23.5 akwazi ukugcina awokuqala. amandla okwanda kwe-in vitro, ukuhlukaniswa, ukunwetshwa kanye nokufakwa kwe-vivo.
Ngo-2018, i-stem cell eqoqwe esibhedlela sase-Beijing Obstetrics and Gynecology yafakwa iqhwa iminyaka engu-20 nezinyanga ezingu-4 ngoJuni 1998. Ngemva kokuvuselelwa, umsebenzi wawungu-99.75%!
Kuze kube manje, kunezindawo zokugcina igazi zezintambo ezingaphezu kuka-300 emhlabeni, ngamaphesenti angu-40 eYurophu, amaphesenti angu-30 eNyakatho Melika, amaphesenti angu-20 e-Asia namaphesenti angu-10 e-Oceania.
I-World Marrow Donor Association (WMDA) yasungulwa ngo-1994 futhi izinze eLeiden, eNetherlands. Enkulu kunayo yonke iNational Marrow Donor Programme (NMDP), ezinze eMinneapolis, eMinn., futhi yasungulwa ngo-1986. I-DKMS inabaxhasi ababalelwa ezigidini ezine, inikela abangaphezu kwezi-4, 000 unyaka ngamunye. I-Chinese Marrow Donor Programme (CMDP), eyasungulwa ngo-1992, iyibhange lesine elikhulu lomnkantsha ngemva kwe-United States, Germany neBrazil. Angakwazi ukuhlukana abe ezinye izinhlobo zamangqamuzana egazi, njengamangqamuzana abomvu egazi, amangqamuzana amhlophe egazi, amaplatelet nokunye.
I-Liquid Nitrogen System Yesitoreji Se-Stem Cell
Isistimu yokugcina i-stem cell ikakhulukazi iqukethe ithangi elikhulu le-nitrogen cryogenic eliwuketshezi, isethi yamapayipi anejakhethi ye-vacuum (okuhlanganisa ipayipi elinejakhethi, ipayipi elinejakhethi, isihlukanisi sesigaba, i-vacuum jacketed stop valve, umgoqo woketshezi lomoya, njll.) isitsha sebhayoloji sokugcina amasampula e-stem cell ethangini.
I-nitrogen ewuketshezi ihlinzeka ngokuvikeleka kwezinga lokushisa eliphansi okuqhubekayo ezitsheni zebhayoloji. Ngenxa yegesi yemvelo ye-nitrogen ewuketshezi, ngokuvamile kuyadingeka ukugcwalisa iziqukathi zebhayoloji kanye ngesonto ukuze kuqinisekiswe ukuthi izinga lokushisa esitsheni sebhayoloji liphansi ngokwanele.
I-HL Cryogenic Equipment
I-HL Cryogenic Equipment eyasungulwa ngo-1992 iwuphawu oluxhumene ne-Chengdu Holy Cryogenic Equipment Company eChina. I-HL Cryogenic Equipment izibophezele ekwakhiweni nasekukhiqizeni i-High Vacuum Insulated Cryogenic Piping System kanye Nezisetshenziswa Zokusekela ezihlobene.
