A ib leeg qis g-force centrifugation kauj ruam ua rau me me cell lysis thiab tiv thaiv kev sib cuag ntawm cov nuclei nrog rau ib puag ncig cytoplasmic. Txoj kev nrawm no qhia tau hais tias muaj kev rov tsim dua tshiab vim yog qhov kev siv ntawm tes me me uas yuav tsum tau ua los ntawm tus neeg tshawb xyuas.
Centrifugation ua li cas rau cov hlwb?
Centrifugation ntawm qhov sib txawv tso cai rau kev sib cais ntawm cov khoom mus rau hauv 'fractions', raws li lawv tau nkag siab npaum li cas (Box 1). Piv txwv li, ntawm qhov qis centrifugation ceev, cov hlwb loj tuaj yeem raug cais tawm ntawm cov hlwb me.
Puas centrifuging tshem tawm cov hlwb tuag?
Kev Sib cais ntawm Cov Tuag thiab Cov Neeg Nyob Los Ntawm Centrifugation
Ib txoj hauv kev yooj yim tshaj plaws ntawm kev tshem tawm cov khib nyiab ntawm tes yog ntom-gradient centrifugation. Qhov ceev-gradient centrifugation harnesses ib lub cuab yeej hu ua lub centrifuge uas tig ib qho sib xyaw heterogenous ntawm kev kub ceev.
Yuav ua li cas thiaj li mob hlwb?
Cov txheej txheem suav nrog khov lub xovtooj ntawm kev ncua hauv qhov qhuavdej khov / ethanol da dej lossis lub tub yees thiab tom qab ntawd muab cov khoom pov tseg hauv chav sov lossis 37 ° C. Cov txheej txheem ntawm lysis no ua rau cov hlwb o thiab thaum kawg tawg raws li cov dej khov nab kuab tsim thaum lub sij hawm khov thiab tom qab ntawd cog lus thaum thawing.
Yuav ua li cas thaum koj centrifuge hlwb nrawm dhau?
Spinning nrawm dhau tuaj yeem ua rau "smear" ntawm cov cell mus rau phab ntsa ntawm lub raj uas koj yuav ploj thaum rov ua duacov hlwb.

Mesenchymal qia hlwb yog multipotent neeg laus qia hlwb uas muaj nyob hauv ntau cov ntaub so ntswg, nrog rau txoj hlab ntaws, pob txha pob txha thiab cov nqaij rog. Mesenchymal qia hlwb tuaj yeem txuas ntxiv nws tus kheej los ntawm kev faib thiab tuaj yeem sib txawv rau ntau cov ntaub so ntswg nrog rau cov pob txha, pob txha mos, cov leeg nqaij thiab cov rog rog, thiab cov ntaub so ntswg sib txuas .
Puas yog tus kws kho mob hlwb puas yog tus kws kho hlwb?
Qhov kev sib piv no, txawm tias tsis zoo tag nrho, tuaj yeem pab nkag siab qhov txawv: Cov kws kho mob tsom mus rau thiab kho cov tsos mob tshwm sim hauv lub hlwb uas ua rau kev ua haujlwm tsis zoo, piv txwv li; tib neeg tus cwj pwm, thaum cov kws kho mob hlwb tsom rau thiab kho cov tsos mob tshwm sim hauv lub hlwb uas ua rau muaj qhov txawv txav tsis txaus ntseeg… Neurology puas yog kev puas siab puas ntsws?
Puas yog lub paj hlwb puas hlwb?
Lub paj hlwb thiab qaum qaum yog lub hauv paus paj hlwb. Cov hlab ntsha uas nkag mus rau tag nrho lub cev ua rau lub paj hlwb peripheral . Puas yog lub hlwb yog qhov loj tshaj ntawm lub paj hlwb? Lub forebrain yog qhov loj tshaj plaws thiab tsim tau zoo tshaj plaws ntawm tib neeg lub hlwb:

ua haujlwm ntawm nws tus kheej ntawm endocrine system. … Cov kab mob endocrine. A) yog hom paj hlwb . Cov hlwb twg yog cov hlwb endocrine? Muaj peb hom kab mob endocrine; alpha cells uas zais glucagon, beta hlwb uas tso cov tshuaj insulin, thiab delta hlwb uas inhibit qhov tso tawm ntawm glucagon thiab insulin:
Puas yog beta hlwb thiab islet hlwb tib yam?
Lub pancreas muaj pawg ntawm cov hlwb uas tsim cov tshuaj hormones. Cov pawg no hu ua islets. … Beta cells ua cov tshuaj hormone insulin, uas txo cov piam thaj. Hauv hom 1 mob ntshav qab zib mellitus, lub cev tiv thaiv kab mob ua yuam kev ua rau cov beta hlwb .
