Kawg, pluripotent qia hlwb yog tam sim no hauv cov neeg laus cov ntaub so ntswg raws li feeb sub-populations hauv qee cov qia cell niches. Cov pej xeem zoo li no twb tau txheeb xyuas thiab tshaj tawm hauv cov pob txha pob txha muab tau los ntawm mesenchymal qia hlwb (Jiang li al., 2002).
Puas yog cov neeg laus qia hlwb pluripotent?
Pluripotent cells tuaj yeem ua rau txhua hom cell uas ua rau lub cev; embryonic qia hlwb suav hais tias yog pluripotent. Multipotent cells tuaj yeem tsim ua ntau tshaj ib hom cell, tab sis muaj tsawg tshaj li pluripotent hlwb; Cov neeg laus qia hlwb thiab qaum cov qe ntshav yog xav ntau ntau
tib neeg puas muaj pluripotent qia hlwb?
Tib neeg pluripotent qia cell: Ib qho ntawm cov cell uas yog tus kheej-replicating, yog muab los ntawm tib neeg embryos los yog tib neeg cov ntaub so ntswg fetal, thiab paub tias yuav loj hlob mus rau hauv cov hlwb thiab cov ntaub so ntswg ntawm peb thawj kab mob txheej.… Tib neeg pluripotent qia hlwb tseem hu ua tib neeg embryonic qia hlwb.
Pluripotent qia hlwb pom nyob qhov twg?
Cov qia hlwb no tuaj ntawm embryos uas muaj hnub nyoog peb mus rau tsib hnub nyob rau theem no, tus embryo hu ua blastocyst thiab muaj txog 150 hlwb. Cov no yog pluripotent (ploo-RIP-uh-tunt) qia hlwb, txhais tau tias lawv tuaj yeem faib ua ntau cov qia hlwb lossis tuaj yeem ua txhua hom cell hauv lub cev.
Cov neeg laus muaj pes tsawg leeg?
Cov neeg laus qia hlwb tau pom nyob rau hauv brain, pob txha, cov hlab ntsha, cov leeg pob txha, tawv nqaij, hniav, plawv, plab, siab, thiab lwm yam (txawm tias tsis yog tag nrho.) lub cev thiab cov ntaub so ntswg.

Puas yog mesenchymal hlwb qia 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 mesenchymal qia hlwb pluripotent lossis multipotent?
Mesenchymal stem cells (MSCs) yog ntau lub hlwb uas tuaj yeem sib txawv rau ntau hom cell, suav nrog pob txha, rog, pob txha mos, nqaij, thiab tawv nqaij (daim duab 14) . Puas yog mesenchymal qia hlwb pluripotent? Piv rau pluripotent qia hlwb nrog cuam tshuam kev pheej hmoo ntawm kev tiv thaiv kab mob tiv thaiv kab mob thiab tsim teratoma, cov neeg laus qia hlwb tshwj xeeb tshaj yog mesenchymal qia hlwb (MSCs) yog hyped los ua ib qho tsim nyog hloov vim lawv kuj nthu
Leej twg nrhiav tau induced pluripotent qia hlwb?
Qhov kev tshawb pom ntawm induced pluripotent qia hlwb (iPSCs) los ntawm Shinya Yamanaka hauv 2006 tau tshaj tawm tias yog qhov kev tawg loj ntawm kaum xyoo hauv kev tshawb fawb qia hlwb . Cov kws tshawb fawb tau tsim cov kab mob pluripotent qia hlwb li cas?
Dab tsi yog induced pluripotent qia hlwb?
Induced pluripotent qia (iPS) hlwb, yog hom pluripotent qia cell muab tau los ntawm cov neeg laus somatic hlwb uas tau raug genetically reprogrammed mus rau lub embryonic qia (ES) cell-zoo li lub xeev los ntawm kev yuam kev. ntawm cov noob thiab yam tseem ceeb rau kev tswj hwm lub ntsiab lus ntawm ES hlwb .
Cov neeg laus laus puas tau them nyiaj kho hniav?
kho hniav dawb yog tias koj lossis koj tus khub tau txais ib qho ntawm cov txiaj ntsig no: Guarantee credit part of Pension Credit. Cov nyiaj tau los txhawb nqa. Cov Nyiaj Tau Los Txog Kev Ua Haujlwm thiab Nyiaj Pab Txhawb . Koj puas tau txais kev kho hniav dawb yog tias koj tau nyiaj laus hauv xeev?
