Qhov sib txawv tseem ceeb ntawm cov kab mob adherent thiab suspension yog tias cov hlwb adherent xav tau kev txhawb nqa zoo rau lawv txoj kev loj hlob thaum lub hlwb raug tshem tawm tsis xav tau kev txhawb nqa rau kev loj hlob.

Ib lub xovtooj yog lub hauv paus txheej txheem thiab kev ua haujlwm ntawm lub cev. Ntau txoj haujlwm tshawb fawb xav tau kev npaj cov kab lis kev cai ntawm tes. Cov kab mob qog noj ntshav, hepatocytes, lub raum hlwb thiab ntau cov kab mob microbial yog qee cov hlwb uas siv hauv cell culturing. Nyob rau hauv tag nrho cov txheej txheem ntawm cell culturing, nws yog ib qhov tsim nyog yuav tsum muaj ib tug thawj cell kab lis kev cai los ua cov kab ntawm tes. Thaum npaj cov kab lis kev cai ntawm tes, cov hlwb muaj nyob rau hauv ob hom xws li cov kab mob sib txuas los yog cov hlwb raug tshem tawm. Nyob rau hauv cov hlwb adherent, thawj kab lis kev cai hlwb xav tau kev pab txhawb nqa kom txuas. Yog li ntawd, lawv yog anchorage-dependent hlwb. Tab sis nyob rau hauv lub ncua kev kawm ntawv hlwb, thawj kab lis kev cai hlwb tsis xav tau kev pab txhawb nqa. Lawv submerge nyob rau hauv cov kua media. Yog li ntawd, lawv tsis yog anchorage depended. Nyob rau hauv tag nrho, qhov sib txawv tseem ceeb ntawm adherent thiab suspension cells yog qhov chaw ruaj khov ntawm cov hlwb.

Dab tsi yog Adherent Cells?

Adherent cell kab yog cov hlwb uas nyob ruaj khov. Yog li ntawd, cov hlwb no xav tau kev txhawb nqa ruaj khov, uas yog hu ua adherent, rau lawv txoj kev loj hlob. Feem ntau ntawm cov hlwb muab tau los ntawm cov vertebrate hlwb (tshwj tsis yog cov hlwb hematopoietic) yog nyob ntawm qhov chaw nres nkoj. Yog li ntawd, kev saib xyuas ntawm feem ntau ntawm cov vertebrate hlwb yuav tsum tau ib tug adherent uas yields ib tug ruaj khov kev loj hlob ntawm cov hlwb.

Daim duab 01: Cov Cells Adherent

Feem ntau ntawm cov kab sib txuas ntawm tes tsim nyob rau hauv cov ntaub so ntswg kho cov hlab ntsha. Yog li ntawd, lawv txoj kev loj hlob ib txwm txwv rau thaj tsam ntawm lub nkoj lossis cov neeg koom nrog. Thaum npaj cov kab mob sib txuas, cov kab mob sib txuas yuav tsum tau trypsinized. Thiab tseem, rov ua dua ntawm cov hlwb yog ua tiav ua ntej npaj ib qho kev sib txuas ntawm tes. Adherent cell kab muaj txiaj ntsig hauv cytogenetics thiab hauv cov haujlwm tshawb fawb sib txawv.

Dab tsi yog Suspension Cells?

Cov hlwb raug tshem tawm yog qhov tsis muaj kev ywj pheej. Yog li ntawd, cov hlwb no tuaj yeem loj hlob raug ncua hauv cov kua nruab nrab. Txhawm rau muab cov xwm txheej zoo rau lawv txoj kev loj hlob, nws yog ib qho tsim nyog yuav tsum sib tov qhov nruab nrab tsis tu ncua los ntawm kev ntxhov siab. Tib neeg cov hlwb hematopoietic yog ib qho ntawm cov kab lis kev cai raug tshem tawm ntawm cov kab lis kev cai uas tau npaj ntau hauv cov chaw sim. Qhov no yog vim qhov tseeb tias lawv tsis xav tau kev pab txhawb nqa rau kev loj hlob.

Kev tu lub hlwb raug ncua yuav tsum muaj kev ntxhov siab tas mus li thiab ob peb txoj kev hla dhau. Qhov tseem ceeb tshaj plaws, qhov concentration ntawm cov as-ham hauv nruab nrab txwv kev loj hlob ntawm cov hlwb hauv nruab nrab. Yog li, dhau sij hawm, cov yam ntxwv loj hlob thiab cov khoom siv hauv xov xwm deplete txwv txoj kev loj hlob ntawm cov hlwb. Yog li ntawd nws yog ib qho tseem ceeb tshaj plaws los tswj tag nrho cov kev xav tau ntawm qhov zoo tshaj plaws kom ua tiav txoj kev loj hlob ntawm cov hlwb raug tshem tawm.

Daim duab 02: Kev ncua Cells hauv Bioreactor

Hauv kev lag luam daim ntawv thov, lub hlwb raug tshem tawm yog hom siv ntau tshaj plaws ntawm cov kab xov tooj tseem ceeb. Nyob rau hauv ob qho tib si tas mus li thiab batch fermentation, ib qho active suspension cell kab lis kev cai ua raws li ib tug pib kab lis kev cai. Tsis tas li ntawd, kev ncua ntawm tes kab lis kev cai tau txais cov khoom lag luam ntau dua li cov kab sib txuas ntawm tes. Lwm qhov kom zoo dua ntawm cov hlwb raug tshem tawm tshaj cov hlwb ua ke yog qhov kev npaj ntawm cov hlwb raug tshem tawm tsis tshua muaj zog thiab yuav tsum tau siv nyiaj tsawg dua hauv kev sib piv rau cov hlwb. Yog li ntawd, kev tsim cov metabolites theem nrab xws li tshuaj tua kab mob, vitamins, amino acids, proteins, thiab lwm yam, tuaj yeem ua tau yooj yim los ntawm kev ncua ntawm tes kab lis kev cai.

Dab tsi zoo sib xws ntawm Adherent thiab Suspension Cells?

  • Adherent thiab Suspension Cells yog ob hom cell uas tau txais los ntawm thawj cov kab ke ntawm tes.
  • Ob leeg xav tau kev tshaj tawm xov xwm zoo thiab cov xwm txheej loj hlob kom ua tiav qhov siab tshaj plaws
  • Ob leeg tau npaj nyob rau hauv vitro mob thiab tuaj yeem khaws cia hauv qhov tshwj xeeb cia.
  • Lawv xav tau kev hla mus tas li txhawm rau nce cov txiaj ntsig.
  • Lawv muaj kev siv rau hauv kev tshawb fawb thiab kev sim.
  • Ob lub hlwb tuaj yeem hloov mus rau hauv lawv cov kab ntawm tes.

Qhov txawv ntawm Adherent thiab Suspension Cells yog dab tsi?

Adherent cells, raws li lub npe qhia, loj hlob txuas mus rau qhov chaw. Nyob rau hauv sib piv, suspension hlwb loj hlob nyob rau hauv ib tug kua nruab nrab yam tsis tau txuas mus rau ib tug nto. Qhov no yog qhov sib txawv tseem ceeb ntawm adherent thiab suspension cells. Tsis tas li ntawd, kev loj hlob ntawm cov hlwb adherent txwv tsuas yog nyob rau hauv thaj tsam ntawm cov adherent thaum, rau cov hlwb raug tshem tawm, tsis muaj qhov txwv. Txawm li cas los xij, ntau yam xws li aeration, cov ntsiab lus ntawm qhov nruab nrab, qhov kub thiab txias, pH thiab lwm yam txwv kev loj hlob ntawm cov hlwb raug tshem tawm.

Summary – Adherent vs Suspension Cells

Thaum peb loj hlob thawj cov hlwb hauv cov kua nruab nrab, nws dhau los ua kev ncua ntawm tes. Nyob rau hauv sib piv rau qhov ntawd, thaum peb tso cai rau cov thawj cell txuas mus rau hauv ib tug khoom nto thiab loj hlob, nws ua ib tug adherent cell kab lis kev cai. Qhov no yog qhov sib txawv tseem ceeb ntawm adherent thiab suspension cells. Yog li cov hlwb adherent yog anchorage-dependent thaum lub hlwb raug tshem tawm yog anchorage ywj siab. Tsis tas li ntawd, kev saib xyuas ntawm cov hlwb raug tshem tawm yuav tsum muaj kev ntxhov siab tas mus li ntawm qhov nruab nrab, tsis zoo li hauv cov hlwb ua ke. Txawm li cas los xij, ob qho tib si adherent thiab suspension cells tuaj yeem hloov mus rau hauv cov kab ntawm tes, uas muaj txiaj ntsig zoo hauv kev tshawb fawb lub hom phiaj thiab hauv kev tshawb fawb kab lis kev cai ntawm tes.
