Hematopoietic stem cells yog pluripotent thiab tsis yog "hematopoietic" Blood Cells Mol Dis.
Puas yog hematopoietic qia hlwb pluripotent lossis multipotent?
Hematopoietic stem cells (HSCs) yog immature multipotent neeg laus qia cov hlwb uas ua rau tag nrho cov qe ntshav loj hlob tuaj, ua kom pom kev mus sij hawm ntev, thiab muaj peev xwm ua kom rov ua tau zoo dua. tag nrho hematopoietic system nyob rau hauv tus neeg tau txais kev mob tom qab infusion.
Puas yog hematopoietic qia hlwb multipotent?
Hematopoietic stem cells (HSCs) yog multipotent, rov ua nws tus kheejcov hlwb progenitor uas tsim los ntawm mesodermal hemangioblast cells. Tag nrho cov qe ntshav sib txawv los ntawm cov kab mob lymphoid thiab myeloid tshwm sim los ntawm HSCs. HSCs tuaj yeem pom muaj nyob rau hauv cov neeg laus cov pob txha, cov ntshav peripheral, thiab cov ntshav qaum.
Lub stem cells yog pluripotent?
Pluripotent cells tuaj yeem ua rau txhua hom cell uas ua rau lub cev; embryonic qia hlwb suav 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 suav tias muaj ntau yam.
YPuas yog myeloid qia cell multipotent?
Nyob hauv cov vertebrates, feem coob ntawm hematopoiesis tshwm sim nyob rau hauv cov pob txha pob txha thiab yog muab los ntawm ib tug tsawg tus naj npawb ntawm hematopoietic qia hlwb uas yog.multipotent thiab muaj peev xwm rov ua dua nws tus kheej. Hematopoietic qia hlwb ua rau muaj ntau hom qe ntshav, hauv kab hu ua myeloid thiab lymphoid.

Puas yog cov kab mob mononuclear qia hlwb?
MNCs yog cov neeg laus qia hlwb uas muaj feem ntawm cov hlwb hauv cov pob txha (BM-MNCs) lossis cov ntshav peripheral (PB-MNCs) uas tsis muaj granules hauv lawv cov cytoplasm thiab muaj ib lub hauv paus nucleus. Puas yog qia hlwb mononuclear?
Dab tsi ua rau pluripotent qia hlwb?
Induced pluripotent stem cells (iPSCs) yog pluripotent qia hlwb tsim los ntawm cov neeg laus los ntawm reprogramming. iPSCs muaj tib lub zog xws li embryonic qia hlwb, thiab yog li nws tus kheej-renew thiab tuaj yeem sib txawv rau txhua hom cell ntawm lub cev tshwj tsis yog cov hlwb hauv cov ntaub so ntswg ntxiv xws li cov placenta.
Puas yog fibroblasts qia hlwb?
Embryonic stem cells (ESCs) thiab induced pluripotent stem cells (iPSC) yog ob hom qia hlwb uas tuaj yeem sib txawv rau ntau hom cell thiab pib pom cov lus cog tseg zoo hauv kev kho cov qia cell. … Fibroblasts yog cells uas yog feem ntau ntawm cov stroma ntawm cov ntaub so ntswg.
Puas yog mesenchymal stromal cells qia hlwb?
Stromal cells - tseem hu ua mesenchymal stem cells (MSCs) - yog non-hematopoietic, ntau lub zog, lub hlwb rov ua dua tshiab uas muaj peev xwm ntawm trilineage sib txawv (mesoderm, ectoderm, thiab endoderm). Puas yog mesenchymal stem cells?
Puas yog placental qia hlwb pluripotent?
Placental qia hlwb yog tsis totipotent, vim tsuas yog ob hom qia hlwb muaj peev xwm no: embryonic qia hlwb, thiab ib hom reprogrammed ntawm qia cell, hu ua induced pluripotent. qia cell (iPS cell). Puas pluripotent stem cells ua placenta?
