Raws li cov kev tshawb fawb tau los ntawm cov koom haum pab tswv yim thoob ntiaj teb, kab mob thiab kev ua kom pom tseeb ntawm kev puas tsuaj ntawm tes. Lub peev xwm ntawm cov hlwb los ua dua lawv tus kheej yuav tsis kam nrog lub hnub nyoog nce. Thaum kev laus thiab muaj mob hlwb txuas ntxiv ua ntxiv, cov hlwb tshiab tsis tuaj yeem hloov lawv hauv lub sijhawm, thiab cov kab mob thiab cov kab mob thiab ua rau pom kev.
Qia hlwb yog ib hom kev tshwj xeeb ntawm tes hauv lub cev uas tuaj yeem tig mus rau ib hom ntawm tes hauv peb lub cev, siv los kho kev puas tsuaj thiab hloov hlwb laus. Nyob rau hauv xyoo tsis ntev los no, nrog kev sib me me ntawm qia cell kev kho mob rau cov kab mob thiab kev tawm tsam cov kev xaiv tseem ceeb rau neeg feem coob noj qab haus huv.
Lub sijhawm cia khoom ntawm qia hlwb hauv cov kua nitrogen system
Theoretically, ua kua nitrogen crypreservent tuaj yeem khaws cov peev txheej ntawm kev tiv thaiv. Tam sim no, cov paub ntev tshaj plaws tau xaiv cov qauv hauv chav kuaj ntawm Suav Academy ntawm kev tshawb fawb hauv Suav teb tau khaws cia rau 70 xyoo. Qhov no tsis txhais tau tias lub khov ntim cia tsuas yog ua tau rau 70 xyoo, tab sis kev txhim kho ntawm tag nrho kev lag luam tsuas muaj keeb kwm 70 xyoo. Nrog rau kev txhim kho ntawm lub sijhawm, lub sij hawm ntawm khov qia hlwb yuav txuas ntxiv txuas ntxiv.
Tau kawg, lub sijhawm ntawm cov duab cryopreserve nyob ntawm ntawm lub cleopreservation kub, raws li tsuas yog crane canofreservation kub tsuas ua tau cell dormant. Nyob rau hauv ib txwm muaj xwm txheej, nws tuaj yeem khaws cia rau 5 teev ntawm chav tsev kub. Tsawg kub 8 degrees Celsius tuaj yeem khaws cia rau 48 teev. Cov tub yees kub feem ntau-28 degrees Celsius tuaj yeem khaws cia rau ib hlis. Ua kua nitrogen yog inoretically mus tas li ntawm -196 degrees Celsius.
Hauv xyoo 2011, cov txiaj ntsig ntawm hauv cov kev sim vitro thiab tsiaj cov ntshav ntawm cov ntshav benpes thiab nws pab neeg ntawm Indiana University khaws cia rau 23,5 xyoo tuaj yeem tswj hwm lawv cov thawj Muaj peev xwm ntawm nyob rau hauv vitro proliferation, sib txawv, nthuav dav thiab hauv vivo implantation.
Nyob rau hauv 2018, lub qia cell sau hauv Beijing hauv tsev kho mob thiab tsev kho mob Gynecology tau khov rau 20 xyoo hauv lub Rau Hli 199. Tom qab kev rov ua haujlwm, cov haujlwm yog 99.75%!
Txog tam sim no, muaj ntau dua 300 txoj kab ntshav ntshav hauv ntiaj teb, nrog 40 feem pua hauv Tebchaws Europe, 20 feem pua hauv Asia thiab 10 feem pua hauv Oceania.
Koom Haum Pob Zeb Ntiaj Teb (WMDA) tau tsim nyob rau xyoo 1994 thiab yog ua raws li hauv Leiden, lub Netherlands. Qhov loj tshaj plaws yog lub tshav pob nees ua haujlwm rau lub teb chaws (NMDP), raws li hauv Minneapolis, Minn., Thiab tsim cov neeg pab nyiaj, muab ntau tshaj 4, 000 txhua xyoo. Suav cov pob txha caj qaum (cmdp), tsim lub pob zeb loj tshaj plaws tom qab Tebchaws Meskas, Tebchaws Yelemees thiab Brazil. Lawv tuaj yeem sib txawv rau lwm cov qe ntshav, xws li cov qe ntshav liab, qe ntshav dawb, plategele thiab lwm yam.
Ua Kua Nitrogen System Rau Qia Cell Cia
Lub qia cell cia cov khoom tsuas yog ua cov kua dej loj Kev txheeb xyuas roj ntsha rau khaws cia qia cell ua piv txwv hauv lub tank.
Ua kua nitrogen muab kev tiv thaiv kub txuas ntxiv hauv kev tiv thaiv biological. Vim yog cov khoom siv ntuj ua kua ntawm cov kua nitrogen, feem ntau nws yog feem ntau tsim nyog sau cov roj ntsha ib zaug ib lub lim tiam kom ntseeg tau tias qhov kub nyob hauv cov thawv roj ntsha yog qis txaus.
Hl cryogenic khoom
Ua cov khoom siv cryogenic uas tau tsim nyob rau xyoo 1992 yog ib hom neeg koom rau Chengdu Cov Khoom Siv Cryogenic Khoom Siv Hauv Suav teb. Siv cov khoom siv cryogenic tau cog lus rau cov qauv tsim thiab tsim cov tshuab nqus tsev siab insulated cryogenic piping system thiab cuam tshuam cov cuab yeej siv.
