Qhov sib txawv tseem ceeb ntawm hematopoiesis thiab hemocytoblast yog tias hematopoiesis yog txheej txheem tsim txhua yam ntawm cov qe ntshav tshiab thaum hemocytoblast yog hematopoietic stem cell uas yog pib qia cell ntawm hematopoiesis.
Haematopoiesis yog txheej txheem uas txhua hom qe ntshav tsim tawm. Hauv fetus, hematopoiesis tshwm sim hauv daim siab thiab tus po. Tom qab yug me nyuam, hematopoiesis tshwm sim hauv cov pob txha pob txha. Stem cells muab cov qe ntshav. Lub qia cell uas tuaj yeem dhau los ua txhua hom ntshav cell hu ua hemocytoblast. Yog li ntawd, nws yog qhov pib cell ntawm hematopoiesis. Nws tseem hu ua hematopoietic qia cell.
Hematopoiesis yog dab tsi?
Lo lus 'hemato' yog hais txog ntshav, thiab 'poiesis' txhais tau tias ua. Yog li, lo lus hematopoiesis yog hais txog kev tsim cov qe ntshav tas li. Qhov no yog txheej txheem cellular tseem ceeb. Muaj peb hom qe ntshav loj xws li cov qe ntshav liab, qe ntshav dawb thiab platelets. Cov txheej txheem uas ua rau txhua hom qe ntshav hu ua hematopoiesis. Kev tsim cov ntshav cell tshwm sim nyob rau hauv cov pob txha pob txha (cov kab noj hniav hauv nruab nrab ntawm cov pob txha tsim los ntawm cov ntaub so ntswg spongy). Yog li, pob txha pob txha yog qhov chaw ntawm hematopoiesis.
Daim duab 01: Hematopoiesis
txheej txheem no pib los ntawm cov kab mob hematopoietic, uas yog hu ua hemocytoblast. Hematopoietic qia hlwb yog pluripotent hlwb, txhais tau tias lawv muaj peev xwm tsim tau tag nrho cov progeny ntawm cov ntshav cell. Lawv kuj muaj peev xwm rov ua dua tus kheej. Cov qia hlwb no tuaj yeem tshwj xeeb rau hauv ob hom kab mob hu ua myeloid cells thiab lymphoid cells. Tag nrho cov qe ntshav poob rau hauv ob pawg no. Muaj 6 hom myeloid loj li erythrocytes (cov qe ntshav liab), megakaryocytes, monocytes, neutrophils, basophils thiab eosinophils. Lymphoid cells muaj ob hom loj xws li T-lymphocytes thiab B-lymphocytes.
Hemocytoblast yog dab tsi?
Hemocytoblast yog cov qia cell uas tsim txhua hom ntshav. Nws yog pluripotential hematopoietic qia cell. Hemocytoblasts yog puag ncig hauv cov duab thiab zoo li lymphocytes. Lawv muaj ib tug loj nucleus thiab cytoplasm uas muaj granules. Tsis tas li ntawd, lawv tuaj yeem hloov kho tus kheej. Lawv muaj mesenchymal keeb kwm. Lawv yog cov hlwb tsis sib xws uas tuaj yeem ua rau tag nrho cov tsim hauv cov ntshav. Feem ntau, nws ua rau muaj ob tus xeeb ntxwv hu ua myeloid thiab lymphoid. Tom qab ntawd ob tug progenies tuaj yeem loj hlob mus rau tag nrho lwm hom cell.
cov qe ntshav liab yog ib yam ntawm cov qe ntshav loj uas thauj cov pa oxygen mus rau cov ntaub so ntswg hauv lub cev los pauv cov pa roj carbon dioxide. Yog tias peb xav txog kev tsim cov qe ntshav liab, hemocytoblast ua ntej dhau los ua proerythroblast thiab tom qab ntawd tsim mus rau hauv cov qe ntshav liab tshiab. Kev tsim cov qe ntshav liab los ntawm hemocytoblast yuav siv sijhawm ob hnub. Peb lub cev ua rau kwv yees li ob lab cov qe ntshav liab txhua ob.
Dab tsi zoo sib xws ntawm Hematopoiesis thiab Hemocytoblast?
- Hematopoiesis pib los ntawm hemocytoblast.
- Hemocytoblasts pom nyob rau hauv cov pob txha pob txha, thiab hematopoiesis tshwm sim hauv cov pob txha.
Qhov txawv ntawm Hematopoiesis thiab Hemocytoblast yog dab tsi?
Hematopoiesis yog txheej txheem uas tsim cov qe ntshav tshiab hauv cov pob txha pob txha thaum hemocytoblast yog cov qia cell uas ua rau tag nrho cov qe ntshav. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm hematopoiesis thiab hemocytoblast.
Summary – Hematopoiesis vs Hemocytoblast
Hematopoiesis yog txheej txheem tsim cov qe ntshav tshiab. Nws pib los ntawm qia cell hu ua hemocytoblast. Yog li, hemocytoblast yog cov kab mob hematopoietic uas ua rau txhua hom qe ntshav. Hemocytoblasts muaj nyob rau hauv cov pob txha pob txha. Hematopoiesis kuj tshwm sim hauv cov pob txha pob txha. Hemocytoblasts yog cov hlwb puag ncig uas zoo li lymphocytes. Lawv muaj ib tug loj puag ncig nucleus. Yog li, qhov no qhia txog qhov sib txawv ntawm hematopoiesis thiab hemocytoblast.
