Reticulocytes yog non-nucleated, tsis paub qab hau RBCs tsim nyob rau hauv cov hlab ntsha ua ntej tso tawm hauv cov ntshav. Kev suav cov reticulocyte yog siv los kwv yees cov qib ntawm cov txiaj ntsig erythropoiesis thiab tuaj yeem pab kuaj mob ntau hom ntshav qab zib.
Qhov txawv ntawm ib qho reticulocyte thiab RBC yog dab tsi?
Tsis zoo li feem ntau lwm cov hlwb hauv lub cev, RBCs paub tab tsis muaj nucleus, tab sis reticulocytes tseem muaj qee yam khoom siv caj ces (RNA). Raws li reticulocytes paub tab, lawv poob qhov kawg ntawm RNA thiab feem ntau tau tsim tag nrho hauv ib hnub ntawm kev tso tawm ntawm cov pob txha mus rau hauv cov ntshav.
Qhov twg hauv qab no muaj cov nucleated RBC?
Nucleated RBC feem ntau tsis pom nyob rau hauv cov ntshav ntawm cov tsiaj noj qab haus huv (cov lej tsawg yuav pom hauv cov dev thiab cov camelids, tab sis feem ntau tsis tshua pom hauv lwm hom). Hom nRBC feem ntau pom hauv cov ntshav yog tag nrho hemoglobinized lossis orthochromic metarubricyte(ib lub xovtooj nrog liab cytoplasm thiab me me pyknotic nucleus).
Lub cell twg yog reticulocyte?
Reticulocytes yog cov qe ntshav liabuas tseem tab tom tsim. Lawv tseem hu ua cov qe ntshav liab tsis paub qab hau. Reticulocytes yog tsim nyob rau hauv cov pob txha pob txha thiab xa mus rau hauv cov hlab ntsha. Kwv yees li ob hnub tom qab lawv tsim, lawv loj hlob mus rau hauv cov qe ntshav liab paub tab.
Vim li cas cov reticulocytes muaj cov nucleus?
Nyob zoo cov ntshav liabcell, nyob rau hauv cov tsiaj, reticulocytes tsis muaj ib tug cell nucleus. Lawv hu ua reticulocytes vim yog ib qho reticular (mesh-zoo li) network ntawm ribosomal RNA uas pom nyob rau hauv lub tshuab ntsuas nrog qee yam stains xws li tshiab methylene xiav thiab Romanowsky stain.
