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 suav tias muaj ntau yam.
Puas yog ib lub xovtooj ntawm tes uas yog qia cell?
Multipotent stem cells muaj peev xwm tsim cov hlwb tshwj xeeb (cov hlwb sib txawv). Piv txwv li cov qe ntshav (multipotent) tuaj yeem tsim mus rau hauv cov qe ntshav liab, qe ntshav dawb lossis platelets (tag nrho cov hlwb tshwj xeeb).
Dab tsi yog cov qia hlwb ntau npaum li cas lawv txawv ntawm pluripotent qia hlwb?
Hom Stem Cells
Pluripotent qia hlwb tuaj yeem faib ua feem ntau, lossis tag nrho, hom cell hauv ib yam kab mob, tab sis tsis tuaj yeem tsim mus rau tag nrho cov kab mob ntawm lawv. tus kheej. Multipotent stem cells tuaj yeem sib txawv rau ntau hom cell hauv ib tsev neeg ntawm cov hlwb, xws li cov qe ntshav.
Puas neural qia cell multipotent lossis pluripotent?
1.2 Neurosphere cell culture
Neural stem cells yog self-renewing and multipotent cells uas tsim cov neurons thiab glial hlwb hauv embryonic thiab neeg laus lub hlwb.
ntau lub qia hlwb nyob qhov twg?
Multipotent stem cells nyob rau hauv the isthmus muaj peev xwm tsim tau peb lub xovtooj ntawm tes uas pom nyob rau hauv lub plab epithelium-mucus-ua lub hlwb, tsim cov kua qaub parietal hlwb, thiab enzyme. - tsim cov zymogenic hlwb.

Could stem cells regrow libs?
Loj hlob tag nrho cov ceg Muaj cov neeg laus qia hlwb, ib hom ntawm tes tsis sib txawv uas tuaj yeem ua tshwj xeeb, uas rov tsim cov leeg, tab sis lawv tsis zoo li qhib. Gardiner tau hais tias "Koj tuaj yeem tsim cov hlab ntsha thiab txawm tias cov hlab ntsha,"
Puas yog acinar cells tsim cov tshuaj insulin?
Tus txiav txiav qhia ob hom parenchymal cov ntaub so ntswg: exocrine acini ducts thiab endocrine islets ntawm Langerhans islets ntawm Langerhans Cov islets ntawm pancreatic lossis islets ntawm Langerhans yog thaj tsam ntawm cov txiav txiav uas muaj nws cov endocrine (Cov tshuaj hormone-producing) hlwb, nrhiav pom nyob rau hauv 1869 los ntawm German pathological anatomist Paul Langerhans.
Puas yog kev sau ntau ntau lossis ntau yam?
Cov npe suav tuaj yeem suav tau lossis suav tsis tau. Feem ntau, feem ntau siv, cov ntsiab lus,ntau daim ntawv kuj tseem yuav muaj cov ntsiab lus Txawm li cas los xij, hauv cov ntsiab lus tshwj xeeb, ntau daim ntawv kuj tuaj yeem yog cov khoom sib xws xws li.
Puas yog stem cells pluripotent?
Embryonic stem cells Lawv yog pluripotent, uas txhais tau tias lawv tuaj yeem loj hlob mus rau ib qho ntawm cov hlwb ntawm cov neeg laus lub cev. Cov kws tshawb fawb ntseeg tias, vim tias lawv muaj pluripotent, thiab loj hlob tau yooj yim, lawv muaj peev xwm zoo tshaj plaws los hloov cov ntaub so ntswg puas lossis ploj lossis lub cev .
Stem cells puas kho tsis tau?
qia hlwb yog cov hlwb qub uas muaj peev xwm faib ua ntau lub hlwb rau kev kho, kev loj hlob, thiab rov tsim dua tshiab. Cov kev tshawb fawb ntawm cov qauv kev sim tau pom tias kev kho mob ntxiv lawm tshob nrog qia cell kho yog gaining txais [
