Qhov Tseem Ceeb - Promyelocyte vs Myelocyte
Granulated cov ntshav muaj xws li eosinophils, basophils, thiab neutrophils uas koom nrog ntau yam haujlwm hauv lub cev. Lub precursor qia hlwb ntawm cov hlwb uas tshwm sim los ntawm hematopoietic qia hlwb yog ntawm myeloid kab. Myeloblasts yog cov hlwb ua ntej ntawm cov qe ntshav granulated. Myeloblasts mam li loj hlob mus rau hauv promyelocytes, myelocytes, metamyelocytes, bands, thiab ntu kom thaum kawg ua rau granulocytes hauv cov ntshav peripheral. Txoj kev loj hlob yog hu ua Granulopoiesis. Promyelocyte yog theem thib ob ntawm Myeloblast kev loj hlob. Myelocyte yog theem peb ntawm Myeloblast kev loj hlob. Qhov sib txawv tseem ceeb ntawm cov promyelocyte thiab myelocyte yog theem ntawm qhov sib txawv nws nthuav tawm. Promyelocytes tsis qhia qhov sib txawv thaum myelocytes qhia qhov txawv.
YPromyelocyte yog dab tsi?
Promyelocyte yog theem thib ob ntawm kev txhim kho Myeloblast. Lub promyelocyte loj dua myeloblast. Nws muaj ib txoj kab uas hla ntawm 12-25µm thiab yog hom cell loj tshaj plaws hauv myeloid series. Nws muaj ib tug tseem ceeb nucleus, thiab lub nucleus yog muab tso rau me ntsis npaj nyob rau hauv lub cytoplasm. Chromatin thiab nucleoli yog qhov tseem ceeb hauv qhov no. Cov qauv kawg ntawm chromatin tuaj yeem txheeb xyuas los ntawm kev soj ntsuam microscopic. Txog rau qhov ua tiav tiav ntawm promyelocyte, chromatins tshwm sim raws li cov qauv zoo. Cov condensed chromatin yog muab tso rau hauv lub nuclear membrane.
Lub cytoplasm ntawm promyelocyte yog granulated, thiab cov granules no yog hu ua thawj azurophilic granules. Txij li thaum lub promyelocyte tsis txawv, nws yog tsim los ntawm basophilic cytoplasm. Lub koom haum cell organelle yog qhov tseem ceeb hauv theem promyelocyte ntawm cov qe ntshav. Lub endoplasmic reticulum (ER) zoo nkaus li dilated vesicles thaum Golgi apparatus nyob rau hauv cheeb tsam perinuclear. Yog li cov promyelocyte yog ib qho active cell uas muaj peev xwm ntawm cell faib. Electron microscopic soj ntsuam tso cai me ntsis sib txawv ntawm cov hlwb.
Daim duab 01: Promyelocyte
Kev kho mob ntawm promyelocytes yog qhov tseem ceeb hauv kev txheeb xyuas cov kab mob leukemia. Leukemic promyelocytes yog ob hom loj. Nws tuaj yeem yog hyper-granular uas muaj Auer rods lossis hypo-granular nrog lub bilobed lossis ib lub folded nucleus. Nyob ntawm ntau yam, cov leukemias tau muab cais ntxiv.
Myelocyte yog dab tsi?
Myelocytes yog nyob rau theem peb ntawm granulopoiesis thiab tau kawm dav vim cov no yog cov hlwb sib txawv. Myelocytes yog peb hom sib txawv xws li, neutrophil, eosinophilic thiab basophilic. Thaum staining, granules ntawm peb hom granulocytes tshwm nyob rau hauv peb xim sib txawv.
Granules ntawm neutrophils - lilac
Granules ntawm eosinophils - txiv kab ntxwv-liab
Granules ntawm basophils - ntshav
Cov qauv ntawm cov myelocyte zoo ib yam li cov promyelocyte tab sis muaj txoj kab uas hla. Lub cell txoj kab uas hla ntawm myelocyte yog nyob ib ncig ntawm 10-20 µm. Lub myelocyte nucleus yog ib qho eccentric nucleus. Lub nucleus yog oval los yog puag ncig hauv cov duab, thiab ib qho kawg yog flattened. Nucleoli thiab chromatin cov qauv tsis yog qhov tseem ceeb heev thiab tsuas yog tuaj yeem pom hauv lub tshuab ntsuas hluav taws xob. Lub myelocyte muaj peev xwm ntawm kev faib tawm ntawm tes, thiab kev loj hlob ntawm cov kab mob myeloid yuav tsum nres ntawm theem ntawm myelocyte.
Daim duab 02: Myelocyte
Granulation hauv myelocyte ua rau nce mus rau ob qho tib si thawj thiab theem nrab granules. Lub azurophilic los yog thawj granules yog tsawg dua nyob rau hauv kev sib piv nrog rau cov thib ob granules nyob rau hauv mature myelocyte. Granulation tuaj yeem txheeb xyuas nyob rau hauv endoplasmic reticulum ib yam nkaus, tab sis tus naj npawb ntawm cov granules tsawg dua li ntawm theem promyelocyte.
Dab tsi zoo sib xws ntawm Promyelocyte thiab Myelocyte?
- Ob leeg yog muab los ntawm cov kab mob myeloid.
- Tus thawj ntawm ob lub hlwb yog Myeloblast.
- Ob lub hlwb koom nrog cov txheej txheem ntawm granulopoiesis thiab ua rau kev loj hlob ntawm granulocytes.
- Ob lub hlwb yog nucleated.
- Ob lub hlwb yog granulated.
- Ob lub hlwb raug faib cell.
- Ob lub hlwb muaj cov qauv xws li endoplasmic reticulum thiab Golgi
- Ob lub hlwb tuaj yeem stained kom pom nyob rau hauv lub teeb pom kev zoo lossis lub tshuab hluav taws xob hluav taws xob.
Qhov txawv ntawm Promyelocyte thiab Myelocyte yog dab tsi?

Summary – Promyelocyte vs Myelocyte
Promyelocytes thiab myelocytes yog cov hlwb uas nyob rau hauv cov kab mob myeloid uas ua rau cov granulocytes; eosinophils, basophils, thiab neutrophils. Cov promyelocytes tsis txawv tsis zoo li myelocytes uas txawv. Ob leeg promyelocytes thiab myelocytes koom nrog hauv granulopoiesis. Kev loj hlob ntawm promyelocytes thiab myelocytes yog kawm los ntawm cov txheej txheem staining thiab nrog kev siv cov txheej txheem microscopic. Kev tshawb fawb ntawm cov hlwb no tseem ceeb hauv kev txheeb xyuas ntau hom kab mob leukemia. Qhov no tuaj yeem piav qhia qhov txawv ntawm promyelocyte thiab myelocyte.
