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.
