Raws li kev tshawb fawb tau los ntawm thoob ntiaj teb cov koom haum tso cai, kab mob thiab senescence ntawm tib neeg lub cev pib los ntawm cell puas. Lub peev xwm ntawm cov hlwb kom rov tsim dua lawv tus kheej yuav poob qis nrog qhov nce ntawm hnub nyoog. Thaum laus thiab mob hlwb txuas ntxiv mus, cov hlwb tshiab tsis tuaj yeem hloov lawv lub sijhawm, thiab cov kab mob thiab kev laus yuav tshwm sim.
Stem cells yog ib hom cell tshwj xeeb hauv lub cev uas tuaj yeem hloov mus rau txhua hom cell hauv peb lub cev, siv los kho kev puas tsuaj thiab hloov cov hlwb laus. Nyob rau hauv xyoo tas los no, nrog rau kev nkag siab ntawm lub tswv yim ntawm qia cell kho rau cov kab mob thiab kev tiv thaiv kev laus, qia cell cryopreservation tau dhau los ua ib qho kev xaiv tseem ceeb rau cov neeg feem coob ntawm kev noj qab haus huv yav tom ntej.
Lub Sijhawm Teev Tseg ntawm Stem Cells hauv Liquid Nitrogen System
Raws li txoj cai, kua nitrogen cryopreservation tuaj yeem khaws cov khoom siv ntawm tes mus tas li. Tam sim no, lub npe hu ua tus qauv khaws cia ntev tshaj plaws hauv chav kuaj ntawm Suav Academy ntawm Kev Tshawb Fawb tau khaws cia rau 70 xyoo. Qhov no tsis tau txhais hais tias cov khoom khov khov tuaj yeem ua tiav rau 70 xyoo, tab sis kev txhim kho tag nrho cov kev lag luam tsuas yog muaj keeb kwm ntawm 70 xyoo. Nrog rau txoj kev loj hlob ntawm Lub Sijhawm, lub sijhawm ntawm cov qia hlwb khov yuav txuas ntxiv mus ntxiv.
Tau kawg, lub sijhawm ntawm cryopreservation thaum kawg yog nyob ntawm qhov ntsuas kub ntawm cryopreservation, vim tias tsuas yog cryopreservation tob tuaj yeem ua rau cov hlwb dormant. Raws li ib txwm muaj, nws tuaj yeem khaws cia rau 5 teev ntawm chav tsev kub. Qhov ntsuas kub qis 8 degrees Celsius tuaj yeem khaws cia rau 48 teev. Cov tub yees txias txias txias -80 degrees Celsius tuaj yeem khaws cia rau ib hlis. Cov kua nitrogen yog theoretically ruaj khov ntawm -196 degrees Celsius.
Hauv xyoo 2011, cov txiaj ntsig ntawm kev sim hauv vitro thiab tsiaj sim luam tawm hauv Ntshav los ntawm xibfwb Broxmeyer thiab nws pab neeg los ntawm Indiana University, uas yog tus kws tshaj lij hauv kev tshawb fawb ntawm qaum BLOOD qia cell biology, ua pov thawj tias qia hlwb khaws cia rau 23.5 xyoo tuaj yeem tswj hwm lawv qhov qub. muaj peev xwm ntawm in vitro proliferation, sib txawv, expansion thiab in vivo implantation.
Hauv xyoo 2018, cov qia cell tau khaws cia hauv Beijing Obstetrics thiab Gynecology Tsev Kho Mob tau khov rau 20 xyoo thiab 4 lub hlis thaum Lub Rau Hli 1998. Tom qab resuscitation, kev ua haujlwm yog 99.75%!
Txog tam sim no, muaj ntau dua 300 lub tsev txhab nyiaj ntshav hauv ntiaj teb, nrog 40 feem pua hauv Europe, 30 feem pua hauv North America, 20 feem pua hauv Asia thiab 10 feem pua hauv Oceania.
Lub Ntiaj Teb Marrow Donor Association (WMDA) tau tsim nyob rau xyoo 1994 thiab nyob hauv Leiden, Netherlands. Qhov loj tshaj plaws yog National Marrow Donor Program (NMDP), nyob rau hauv Minneapolis, Minn., thiab tsim nyob rau hauv 1986.DKMS muaj txog 4 lab tus neeg pub dawb, muab ntau tshaj 4,000 txhua xyoo. Suav Marrow Donor Program (CMDP), tsim nyob rau xyoo 1992, yog lub txhab nyiaj loj thib plaub tom qab Tebchaws Meskas, Lub Tebchaws Yelemees thiab Brazil. Lawv tuaj yeem sib txawv rau lwm hom ntshav, xws li cov qe ntshav liab, qe ntshav dawb, platelets thiab lwm yam.
Liquid Nitrogen System rau Stem Cell Cia
Lub qia cell cia qhov system feem ntau muaj cov kua nitrogen loj loj cryogenic tank, ib txheej ntawm lub tshuab nqus tsev cov kav dej (xws li lub tshuab nqus tsev vacuum, lub tshuab nqus tsev hose, theem sib cais, lub tshuab nqus tsev vacuum nres valve, cua-kua barrier, thiab lwm yam.) biological thawv rau khaws cov qia cell hauv lub tank.
Cov kua nitrogen muab kev tiv thaiv kub tsis tu ncua hauv cov ntim khoom lom. Vim yog lub ntuj gasification ntawm cov kua nitrogen, feem ntau nws yog ib qho tsim nyog yuav tsum tau sau cov ntim khoom lom neeg ib zaug ib lub lim tiam kom ntseeg tau tias qhov kub thiab txias hauv cov thawv ntim roj ntsha tsis txaus.
HL Cryogenic khoom
HL Cryogenic Equipment tau tsim muaj nyob rau hauv 1992 yog ib hom lag luam koom nrog Chengdu Holy Cryogenic Equipment Company hauv Suav teb. HL Cryogenic Equipment tau cog lus rau kev tsim thiab tsim khoom ntawm High Vacuum Insulated Cryogenic Piping System thiab cov cuab yeej txhawb nqa.
