Ngokwemiphumela yocwaningo yezikhungo ezigunyaziwe zomhlaba jikelele, izifo kanye nesendensi yomzimba womuntu ziqala kusuka kumonakalo weseli. Amandla amaseli wokuvuselela azokwehla ngokwanda kweminyaka. Lapho amaseli asegugile namaseli anesifo aqhubeka nokuqongelela, amaseli amasha awakwazi ukuwafaka esikhundleni sabo ngesikhathi, kanye nezifo kanye nensempe kuyenzeka ngokungenakuphikiswa.
Amaseli we-Stem anguhlobo olukhethekile lweseli emzimbeni olungaphenduka noma yiluphi uhlobo lweseli emzimbeni wethu, olusetshenziselwa ukulungisa umonakalo bese ubeka amaseli aguga. Eminyakeni yamuva nje, ngokujula komqondo we-stem cell ukwelashwa kwezifo kanye nomphumela wokulwa nokuguga, i-stem cell cropreservation isiphenduke isinqumo esibalulekile sempilo yabantu abaningi bezempilo.
Isikhathi sokugcina samaseli we-stem ohlelweni lwe-nitrogen oluwuketshezi
Ngokweqiniso, ukugcinwa kwe-nitrogen ye-nitrogen kungagcina izinsiza zeselula unomphela. Njengamanje, isampula eyaziwayo yeseli elaziwayo elabhorethri le-Chinese Academy of Science ligcinwe iminyaka engama-70. Lokhu akusho ukuthi isitoreji eqandisiwe senziwa kuphela iminyaka engama-70, kepha ukuthuthukiswa komkhakha wonke kunemilando yeminyaka engama-70. Ngokuthuthukiswa kwezikhathi, isikhathi samaseli we-Frozen Stem azothuthukiswa ngokuqhubekayo.
Vele, isikhathi sokulondolozwa ekugcineni sincike ekuvikeleni kwe-cropressation, njengoba kuphela ama-crimepreserve ajulile angenza amaseli athule. Ngaphansi kwezimo ezijwayelekile, ingagcinwa amahora angama-5 ekushiseni kwegumbi. Izinga lokushisa eliphansi 8 degrees Celsius lingagcinwa amahora angama-48. Amazinga okushisa aphansi aphansi -80 degrees Celsius angagcinwa inyanga eyodwa. I-nitrogen ewuketshezi ihlala unomphela ku--196 degrees Celsius.
Ngo-2011, imiphumela yokuhlolwa kwe-vitro kanye nezilwane ezishicilelwe egazini nguProfessor Broxmeyer kanye nethimba lakhe elivela e-Indiana University, okunguchwepheshe ocwaningweni olugcinwe iminyaka engama-23,5 lungagcina okwabo Amandla we-VITRO ekwanda, umehluko, ukunwetshwa kanye nokufakwa kweVIVO.
Ngo-2018, iseli lesiqu eliqoqwe eBeijing Sherttemic kanye nesibhedlela se-Gynecology saqandelwa iminyaka engama-20 kanye nezinyanga ezi-4 ngoJuni 1998. Ngemuva kokuvuselelwa kabusha, umsebenzi wawungama-99.75%!
Kuze kube manje, kunamabhange egazi angaphezu kwama-300 emhlabeni, anamaphesenti angama-40 eYurophu, amaphesenti angama-30 eNyakatho Melika, amaphesenti angama-20 e-ASIA namaphesenti ayishumi e-Oceania.
I-World Marrow Donor Association (WMDA) yasungulwa ngonyaka we-1994 futhi isuselwe eLeiden, eNetherlands. Okukhulu kakhulu uhlelo lweNational Marrow Donor Programme (NMDP), olususelwa eMinneapolis, eMinn., Futhi kusungulwe ngo-1986.dkms kunabanikeli abacishe babe yizigidi ezi-4, okunika okungaphezulu kuka-4, 000 unyaka ngamunye. Uhlelo lweChinese Marlow Donor (CMDP), olusungulwe ngo-1992, lusebhange lesine elikhulu kunazo zonke ngemuva kwe-United States, eJalimane naseBrazil. Bangahlukanisa ezinye izinhlobo zamangqamuzana egazi, njengamangqamuzana abomvu egazi, amaseli amhlophe egazi, ama-platelet nokunye.
Uhlelo lwe-nitrogen oluwuketshezi lwesitoreji se-stem cell
Uhlelo lokugcina amaseli wesisu ikakhulukazi luqukethe ithangi elikhulu le-nitrogen cryrogenic, iqoqo lesistimu ye-vacuum jacket, i-vactuum jacket, isihlukanisi sesigaba, isithiyo sokumisa i-vacket, isithiyo somoya, njll.) Ne Isitsha sebhayoloji sokugcina amasampula weseli ethangi.
I-Nitrogen ewuketshezi ihlinzeka ngokuvikelwa okuqhubekayo okuphansi kwezinga lokushisa ezitsheni zebhayoloji. Ngenxa yokufuzwa kwemvelo kwe-nitrogen ewuketshezi, kuvame ukudingekile ukugcwalisa iziqukathi zebhayoloji kanye ngesonto ukuqinisekisa ukuthi izinga lokushisa esitsheni sebhayoloji liphansi ngokwanele.
Imishini ye-HL Cryogenic
Imishini ye-HL Cryogenic eyasungulwa ngo-1992 ingumuntu oxhumene ne-Chengdu Holy Cryogenic Equiment Company in China. Imishini ye-HL Crygenic izimisele ekwakhiweni nasekukhiqizweni kwesistimu ephezulu ye-cryogenic insud ye-cryogening kanye nemishini yokusekelwa ehlobene.
Ngeminye imininingwane, sicela uvakashele iwebhusayithi esemthethweniwww.hlcrcro.com, noma i-imeyili ku-info@cdholy.com.
