Erythroid precursors • Cov qe ntshav liab zoo li qub. ua los ntawm cov pob txha pob txha erythroid precursors los yog erythroblasts. • Qhov ntxov tshaj plaws morphologically pom tau tias ua ntej ntawm tes liab yog muab los ntawm ib qho erythroid progenitor cell uas tig los yog tau los ntawm ntau qhov haemopoietic progenitor cell.
Cov lus nug tseem yog, dab tsi yog erythroid cell?
HSCs maj mam faib hlwb uas ua rau pom kev rov ua haujlwm mus sij hawm ntev (LT-HSCs) thaum hloov mus rau pob txha pob txha. Nyob rau hauv cov pob txha pob txha, HSCs sib txawv raws ntau yam kab mob hematopoietic, ib txheej txheem uas yog tswj hwm los ntawm kev ua haujlwm ntawm ntawm tes -thiab hom kev qhia tshwj xeeb.
Ib yam nkaus, erythroid ua ntej yog dab tsi? Erythroid Precursor Xovtooj. Cells nyob rau hauv erythroid series muab los ntawm MYELOID PROGENITOR CELLS lossis los ntawm ob-muaj peev xwm MEGAKARYOCYTE- ERYTHROID PROGENITOR CELLS uas thaum kawg ua rau cov ntshav liab paub tab.
Ib sab saum toj no, cov theem ntawm erythropoiesis yog dab tsi?
Cov theem yog raws li hauv qab no:
- Hemocytoblast, uas yog pluripotent hematopoietic qia cell.
- Common myeloid progenitor, ib tug multipotent qia cell.
- Unipotent qia cell.
- Pronormoblast.
- Basophilic normoblast tseem hu ua erythroblast.
- Polychromatophilic normoblast.
- Orthochromatic normoblast.
- Reticulocyte.
Normoblastic txhais li cas?
Kev kho mob Txhais ntawm nomoblast : cov qe ntshav liab tsis paub qab hau uas muaj hemoglobin thiab cov pyknotic nucleus thiab ib txwm muaj nyob rau hauv cov pob txha tab sis tshwm sim hauv cov ntshav hauv ntau cov ntshav ntshav - piv erythroblast.

Dab tsi yog glycoprotein dab tsi yog ib qho ntawm kev siv glycoproteins?
Glycoproteins yog cov protein uas muaj cov oligosaccharide saw (glycans) covalently txuas nrog cov amino acid sab-saw. Glycoproteins kuj tseem yog ib qho tseem ceeb ua ke ntawm cov protein, uas lawv ua lub luag haujlwm hauv kev sib cuam tshuam ntawm tes -cell
Dab tsi yog intraoral tiav series?
INTRAORAL - TUS QAUV QAB NTUJ NTAWM RADIOGRAPHIC IMAGES. Kev tshuaj ntsuam hluav taws xob ntawm tag nrho lub qhov ncauj, feem ntau suav nrog 14-22 periapical thiab tom qab tom cov duab tom qab npaj los tso saib cov yas thiab cov hauv paus hniav ntawm txhua tus hniav, thaj chaw periapical thiab pob txha alveolar
Puas yog Apple Watch 3 series kos resistant?
Apple Watch Series 3 (42mm) Stainless SteelCase nrog GPS + Cellular tau txais cov qhab nia siab rau kev suav cov kauj ruam thiab kev ntsuas lub siab. Lub moos, uas pib ntawm $ 499, tseem muaj qhov zoo ntawm qhov khawb tsis kam, nrog sapphire siv lead ua iav saum nws lub ntsej muag muaj sia nyob peb qhov zoo tshaj plaws
Case report thiab case series yog dab tsi?
Case Reports thiab Case Series. Daim ntawv ceeb toom yog ib daim ntawv qhia ntxaws txog kev kuaj mob, kev kho mob, teb rau kev kho mob, thiab kev soj ntsuam tom qab kev kho mob ntawm tus neeg mob. Ib rooj plaub yog pawg ntawm cov ntaub ntawv hais qhia txog cov neeg mob uas tau txais kev kho zoo ib yam
