Raws li cov txiaj ntsig tshawb fawb ntawm cov koom haum thoob ntiaj teb, cov kab mob thiab kev laus ntawm tib neeg lub cev pib los ntawm kev puas tsuaj ntawm cov hlwb. Lub peev xwm ntawm cov hlwb los rov tsim dua lawv tus kheej yuav poob qis nrog rau kev nce hnub nyoog. Thaum cov hlwb laus thiab cov kab mob txuas ntxiv sib sau ua ke, cov hlwb tshiab tsis tuaj yeem hloov lawv raws sijhawm, thiab cov kab mob thiab kev laus yuav tshwm sim.
Cov hlwb noob (stem cell) yog ib hom hlwb tshwj xeeb hauv lub cev uas tuaj yeem hloov mus ua txhua hom hlwb hauv peb lub cev, siv los kho qhov puas tsuaj thiab hloov cov hlwb laus. Nyob rau xyoo tas los no, nrog rau kev nkag siab tob txog lub tswv yim ntawm kev kho cov hlwb noob rau cov kab mob thiab cov txiaj ntsig tiv thaiv kev laus, kev khaws cia cov hlwb noob tau dhau los ua qhov kev xaiv tseem ceeb rau kev noj qab haus huv yav tom ntej ntawm cov neeg feem coob.
Lub Sijhawm Khaws Cia ntawm Cov Qog Ntshav Hauv Lub Tshuab Nitrogen Ua Kua
Hauv kev xav, kev siv kua nitrogen cryopreservation tuaj yeem khaws cov peev txheej ntawm lub hlwb mus ib txhis. Tam sim no, cov qauv hlwb ntev tshaj plaws uas paub hauv chav kuaj mob ntawm Suav Academy of Sciences tau khaws cia rau 70 xyoo. Qhov no tsis tau txhais hais tias kev khaws cia khov tsuas yog ua tau rau 70 xyoo, tab sis kev txhim kho ntawm tag nrho kev lag luam tsuas yog muaj keeb kwm ntawm 70 xyoo. Nrog rau kev txhim kho ntawm The Times, lub sijhawm ntawm cov hlwb khov yuav txuas ntxiv mus.
Tau kawg, lub sijhawm ntawm kev khaws cia rau hauv qhov chaw txias kawg nyob ntawm qhov kub ntawm kev khaws cia rau hauv qhov chaw txias, vim tias tsuas yog kev khaws cia rau hauv qhov chaw txias tob xwb thiaj li ua rau cov hlwb pw tsaug zog. Hauv qhov xwm txheej ib txwm muaj, nws tuaj yeem khaws cia rau 5 teev ntawm qhov kub thiab txias hauv chav. Qhov kub qis 8 degrees Celsius tuaj yeem khaws cia rau 48 teev. Lub tub yees txias tob qis -80 degrees Celsius tuaj yeem khaws cia rau ib hlis. Cov kua nitrogen yog qhov ruaj khov tas mus li ntawm -196 degrees Celsius.
Xyoo 2011, cov txiaj ntsig ntawm kev sim hauv vitro thiab tsiaj txhu tau luam tawm hauv Blood los ntawm Xibfwb Broxmeyer thiab nws pab neeg los ntawm Indiana University, uas yog ib tug kws tshaj lij hauv kev tshawb fawb ntawm cov hlwb qia hlwb ntawm cov hlab ntsha hauv caj pas, tau ua pov thawj tias cov hlwb qia hlwb khaws cia rau 23.5 xyoo tuaj yeem tswj hwm lawv lub peev xwm qub ntawm kev loj hlob hauv vitro, kev sib txawv, kev nthuav dav thiab kev cog rau hauv vivo.
Xyoo 2018, ib lub noob hlwb uas tau sau los ntawm Tsev Kho Mob Beijing Obstetrics thiab Gynecology tau khov rau 20 xyoo thiab 4 lub hlis thaum Lub Rau Hli 1998. Tom qab ua kom lub cev rov qab muaj zog, qhov kev ua haujlwm yog 99.75%!
Txog tam sim no, muaj ntau tshaj 300 lub txhab ntshav txuas hauv ntiaj teb, nrog rau 40 feem pua nyob hauv Tebchaws Europe, 30 feem pua nyob rau hauv North America, 20 feem pua nyob rau hauv Asia thiab 10 feem pua nyob rau hauv Oceania.
Lub Koom Haum Pub Ntshav Qab Zib Thoob Ntiaj Teb (WMDA) tau tsim muaj xyoo 1994 thiab nyob hauv Leiden, Netherlands. Qhov loj tshaj plaws yog National Marrow Donor Program (NMDP), nyob hauv Minneapolis, Minn., thiab tau tsim muaj xyoo 1986. DKMS muaj kwv yees li 4 lab tus neeg pub ntshav, muab ntau dua 4,000 txhua xyoo. Chinese Marrow Donor Program (CMDP), tau tsim muaj xyoo 1992, yog lub txhab nyiaj ntshav qab zib thib plaub loj tshaj plaws tom qab Tebchaws Meskas, Lub Tebchaws Yelemees thiab Brazil. Lawv tuaj yeem hloov pauv mus rau lwm hom qe ntshav, xws li qe ntshav liab, qe ntshav dawb, platelets thiab lwm yam.
Cov Kua Nitrogen System rau Kev Khaws Cia Stem Cell
Lub kaw lus cia cov hlwb ntawm cov noob feem ntau muaj lub tank loj uas muaj kua nitrogen cryogenic, ib txheej ntawm cov kav dej uas muaj lub tshuab nqus tsev (xws li cov kav dej uas muaj lub tshuab nqus tsev, cov kav dej uas muaj lub tshuab nqus tsev, cov kav dej uas muaj lub tshuab nqus tsev, cov qhov dej uas muaj lub tshuab nqus tsev, cov qhov dej uas muaj lub tshuab nqus tsev, cov qhov dej uas muaj lub tshuab nqus tsev, cov cua uas muaj kua, thiab lwm yam) thiab lub thawv rau khaws cov qauv hlwb ntawm cov noob hauv lub tank.
Cov kua nitrogen muab kev tiv thaiv tas mus li qhov kub qis hauv cov thawv ntim khoom siv rau tsiaj txhu. Vim yog cov pa roj ntuj ntawm cov kua nitrogen, feem ntau nws yuav tsum tau sau cov thawv ntim khoom siv rau tsiaj txhu ib zaug ib lub lim tiam kom ntseeg tau tias qhov kub hauv cov thawv ntim khoom siv rau tsiaj txhu qis txaus.
Cov Khoom Siv Cryogenic HL
HL Cryogenic Equipment uas tau tsim muaj xyoo 1992 yog ib lub npe koom tes nrog Chengdu Holy Cryogenic Equipment Company hauv Suav teb. HL Cryogenic Equipment tau cog lus rau kev tsim thiab tsim cov High Vacuum Insulated Cryogenic Piping System thiab lwm yam khoom siv txhawb nqa.
