Qhov sib txawv tseem ceeb ntawm pluripotent thiab multipotent qia hlwb yog tias cov pluripotent hlwb muaj peev xwm sib txawv rau txhua hom cell ntawm peb txheej kab mob thaum cov qia hlwb muaj peev xwm tsim tau rau hauv ib qho kev txwv ntawm cov cell tshwj xeeb. yam.
Qee lub hlwb muaj peev xwm sib txawv rau lwm hom hlwb tshwj xeeb. Qhov peev xwm no hu ua cell potency. Thaum lub cell muaj peev xwm sib txawv rau ntau hom cell, cov cell tshwj xeeb muaj peev xwm zoo heev. Ib yam li ntawd, cov qia hlwb muaj lub zog zoo ntawm tes. Lawv yog cov tsis txawv txav ntawm cov kab mob ntau yam kabmob uas tuaj yeem faib tau sai thiab sib txawv rau lwm hom cell. Raws li, muaj ob lub ntsiab ntawm cov qia hlwb. Namely, lawv yog embryonic qia hlwb thiab cov laus qia hlwb. Raws li lub peev xwm los sib txawv rau hauv hom cell, qee cov qia hlwb yog totipotent thaum qee qhov pluripotent thiab multipotent. Pluripotent qia hlwb tuaj yeem dhau los ua txhua hom hlwb hauv peb txheej kab mob thaum cov qia hlwb muaj peev xwm sib txawv rau hauv hom cell tshwj xeeb. Raws li, embryonic qia hlwb yog pluripotent hlwb. Ntawm qhov tod tes, cov qe ntshav yog cov qia hlwb ntau ntau.
Pluripotent Stem Cells yog dab tsi?
Pluripotent qia hlwb yog cov hlwb tsis sib xws uas tshwm sim thaum lub sij hawm embryonic txoj kev loj hlob. Cov hlwb no muaj peev xwm sib txawv rau txhua hom cell ntawm peb txheej kab mob; endoderm, ectoderm, thiab mesoderm. Embryonic qia hlwb yog qhov piv txwv zoo tshaj plaws rau pluripotent qia hlwb. Tsis tas li ntawd, pluripotency tuaj yeem ua tiav los ntawm kev ntxias nws.
Daim duab 01: Pluripotent Stem Cells
Ib lub xovtooj tsis yog pluripotent hloov mus rau hauv lub xovtooj ntawm pluripotent induced los ntawm kev yuam kev qhia ntawm qee cov noob caj noob ces thiab kev hloov pauv. Nyob rau hauv txoj kev no, ib tug neeg laus somatic cell uas tsis pluripotent yuav hloov mus rau hauv induced pluripotent cell. Cov induced pluripotent qia hlwb yog ib qho tseem ceeb hauv kev tsim tshuaj thiab ua qauv ntawm cov kab mob.
Dab tsi yog Multipotent Stem Cells?
Multipotent stem cells yog cov hlwb uas muaj peev xwm sib txawv rau ntau tshaj ib hom cell. Txawm li cas los xij, tsis zoo li pluripotent qia hlwb, cov hlwb no tuaj yeem sib txawv rau hauv ib qho tsawg ntawm cov cell tshwj xeeb. Hauv lwm lo lus, lawv muaj qhov sib txheeb qis dua li cov pluripotent qia hlwb. Lub peev xwm ntawm kev sib txawv txwv rau hauv hom cell nyob rau hauv ib hom kab mob.
Daim duab 02: Ntau lub Stem Cells
Qhov piv txwv zoo tshaj plaws rau cov qia hlwb uas muaj ntau lub zog yog cov qia hlwb. Ntshav qia cell tuaj yeem sib txawv rau hauv cov qe ntshav xws li lymphocytes, monocytes, neutrophils, thiab lwm yam. Cov neeg laus qia hlwb, neural stem cells thiab mesenchymal qia hlwb kuj yog hom kab mob ntau yam. Lawv muaj peev xwm rov ua dua tus kheej; yog li ntawd, lawv muaj nyob rau hauv ntau cov ntaub so ntswg ntawm ib tug neeg laus. Multipotent qia hlwb yog ib qho tseem ceeb hauv kev kho mob ntawm cov kab mob xws li txha caj qaum, pob txha pob txha, kab mob autoimmune, mob caj dab rheumatoid, hematopoietic defects, thiab fertility preservation.
Dab tsi zoo sib xws ntawm Pluripotent thiab Multipotent Stem Cells?
- Pluripotent thiab multipotent qia hlwb muaj peev xwm sib txawv rau lwm hom hlwb.
- Tsis tas li, lawv yog cov hlwb tsis txawv lossis cov hlwb tsis tshwj xeeb.
- Tsis tas li ntawd, ob hom muaj qhov sib txheeb qis dua li cov kab mob totipotent.
- Pluripotent qia hlwb tau txais kev tshwj xeeb rau hauv ntau lub qia hlwb.
Qhov txawv ntawm Pluripotent thiab Multipotent Stem Cells yog dab tsi?
Pluripotent thiab multipotent qia hlwb yog ob hom qia hlwb, uas yog cov hlwb tsis txawv. Txawm li cas los xij, qhov sib txawv ntawm pluripotent thiab multipotent qia hlwb yog tias pluripotent qia hlwb muaj zog ntau dua li cov qia hlwb ntau. Nws yog vim qhov tseeb tias, pluripotent qia hlwb muaj peev xwm sib txawv rau ntau hom cell thaum cov qia hlwb muaj peev xwm los sib txawv rau hauv cov kab mob tsawg tsawg hauv cov kab mob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm pluripotent thiab multipotent qia hlwb.
Cov hauv qab no infographic ntawm qhov sib txawv ntawm pluripotent thiab multipotent qia hlwb qhia ntau qhov sib txawv ntawm ob qho tib si nrog piv txwv.
Summary – Pluripotent vs Multipotent Stem Cells
Totipotency, pluripotency, multipotency thiab unipotency yog plaub yam sib txawv ntawm cell potency. Pluripotent qia hlwb muaj peev xwm sib txawv rau hauv txhua hom cell ntawm peb txheej kab mob. Ntawm qhov tod tes, multipotent qia hlwb muaj peev xwm ua kom sib txawv rau hauv cov cell tshwj xeeb hauv ib hom kab mob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm pluripotent thiab multipotent qia hlwb. Tsis tas li ntawd, pluripotent hlwb muaj nyob rau hauv blastocyst thaum lub cev muaj zog ntau ntau pom nyob rau hauv ntau cov ntaub so ntswg ntawm tus neeg laus. Qhov piv txwv zoo tshaj plaws ntawm pluripotent qia hlwb yog embryonic qia hlwb thaum qhov piv txwv zoo tshaj plaws ntawm cov qia hlwb yog cov qe ntshav.
