Ngokweziphumo zophando lwamaziko agunyazisiweyo amanye amagunya, izifo kunye ne-sunescence yomzimba womntu aqala ukonakalisa kwiseli. Amandla eeseli ukuba aziphinde azivelise ngokwabo uyakohlwaya ngokunyuka kweminyaka. Xa iiseli ezixineneyo kunye nezifo ezinesifo ziyaqhubeka nokuqokelelwa, iiseli ezintsha azikwazi ukuzibeka endaweni yazo ngexesha, kunye nezifo kunye ne-Senecetince yenzeka ngokungathandabuzekiyo.
Iiseli ze-STE luhlobo olukhethekileyo lwesisele emzimbeni onokuthi ujike kube naluphi na uhlobo lweseli emzimbeni wethu, esetyenziselwa ukulungisa umonakalo kwaye ithathe indawo yeeseli zokwaluphala kwaye zibuyise iiseli zokwaluphala. Kwiminyaka yakutshanje, kunye nokukhulisa umxholo wonyango lwe-stems kwizifo kunye nefuthe lokwaluphala, i-stem ye-stem ingaba lukhetho olubalulekileyo kwimpilo yexesha elizayo yabantu.
Ixesha lokugcina iiseli zesiqu kwinkqubo ye-nitrogen ye-nitrogen
Ithiyori, i-nitrogen i-nitrogen cryopreloment inokugcina izixhobo ezingapheliyo. Okwangoku, isampulu eyaziwayo ende ende kwilebhu yelebhu ye-Chinese Academy yeSayensi igcinwe iminyaka engama-70. Oku akuthethi ukuba indawo yokugcina i-frozen inokwenziwa kuphela iminyaka engama-70, kodwa ukuphuculwa komzi mveliso kuphela unembali yeminyaka engama-70. Ngokuphuhliswa kwamaxesha, ixesha leeseli ze-frozen stem ziya kwandiswa rhoqo.
Ewe kunjalo, ixesha lokukhala koxolo ekugqibeleni lixhomekeke kubushushu be-cryupre Phantsi kweemeko eziqhelekileyo, inokugcinwa iiyure ezi-5 kubushushu begumbi. Iqondo lokushisa eliphantsi i-8 degrees lingagcinwa iiyure ezingama-48. I-Festrierators ezinzulu zeqondo lobushushu -80 80 degrees Celsius zinokugcinwa kangangenyanga. I-nitrogen ye-witrogen yi-theoretirely isigxina kwi-196 degrees celsius.
Ngo-2011, iziphumo ze-vitro kunye neemvavanyo zezilwanyana ezipapashwe kwigazi nguNjingalwazi weBhuti ye-Indiana, eyingcali ye-biology ye-Stem, eqondakalanga ukuba i-stem igcinwe i-23,5 iminyaka yangaphambili Inokwenzeka ye-vitroferiferation, umahluko, ukwanda kunye nokufakwa kwe-vivo.
Ngo-2018, ifowuni ye-STE eqokelelwa kwiBeijing Abstetrics kunye ne-Gynecology yayiqhwabaleka iminyaka engama-20 kunye neenyanga ezi-4 ngoJuni 1998. Emva kokunconywa, umsebenzi waba yi-99.75%!
Ukuza kuthi ga ngoku, zingaphezulu kwe-300 yeebhanki zegazi emhlabeni, ngama-40 epesenti yaseYurophu, ama-30 epesenti eMntla Merika, ipesenti ezingama-20 e-Ania kunye ne-10 pesenti elwandle kunye ne-10 pesenti elwandle kunye ne-10 pesenti elwandle kunye ne-10 pesenti elwandle.
Umbutho onguMbutho weHlabathi weHlabathi (WMDA) wasungulwa ngo-1994 kwaye usekwe kwi-Leiden, eNetherlands. Esona sikhulu seNkqubo yeNkqubo yeMarnor yeSizwe (i-NMDP), esekwe eMinneapolis, Minn., Kwaye wamiselwa ngo-1986. Iprogram yase-ChinaRor ye-Chinar Ponor (i-CMDP), esekwe ngo-1992, yibhanki yesine enkulu yeBhanki emva kwe-United States, iJamani neBrazil. Banokwazisa kwezinye iintlobo zeeseli zegazi, ezinje ngeeseli ezibomvu zegazi, iiseli ezimhlophe zegazi, iiplatelets njalo njalo.
Inkqubo ye-nitrogen ye-itrogen yesixhobo seseli stem
Inkqubo yokugcina i-stem ikakhulu iquka itanki enkulu ye-vackogen ye-vacuum, iseti ye-vackeum rackeum (kubandakanya i-vackeum rackeum pipe, i-vacuum jacket hose, i-vacuum jacker, i-vacuum ye-valuum, njl.) Kunye ne Isitya sebhayiloji yokugcina iisampulu zekhephu kwitanki.
I-nitrojen yolwelo ibonelela ngokhuseleko lweqondo lobushushu eliphantsi eliphantsi kwizikhongozeli zebhayoloji. Ngenxa yerhasi yendalo ye-nitrogen ye-nitrogen, ihlala iyimfuneko ukuzalisa iziqulathweni zebhayoloji kanye ngeveki ukuqinisekisa ukuba iqondo lobushushu kwisitya sebhayoloji siphantsi ngokwaneleyo.
Izixhobo ze-HL Crygenic
Izixhobo ze-HL Crygenagec ezazisekwe ngo-1992 luphawu olunxulumene ne-cheng cheng cheng cheyogenic senkampani eTshayina. Izixhobo ze-HL Crygenic zizibophelele kuyilo nakwimveliso yeNkqubo yokuGcina i-CryOgen ye-Crygenic ye-Crygesic kunye nezixhobo zenkxaso ezinxulumene noko.
