Lymphocyte vs Lymphoblast
Lymphocyte thiab lymphoblast yog cov qe ntshav dawb thiab tuaj yeem pom hauv cov hlab ntsha peripheral. Cov hlwb no tseem ceeb heev kom tswj tau qee yam kev tiv thaiv kab mob hauv lub cev. Lymphocyte yog tsim nyob rau hauv thawj thiab theem nrab lymphoid kab mob. Thaum lub sij hawm maturation ntawm lymphocyte, nws mus rau peb-cell theem; lymphoblast, prolymphocyte thiab mature lymphocyte. Ntau qhov sib txawv morphological muaj nyob ntawm cov theem ntawm tes.
YLymphocyte yog dab tsi?
Lymphocyte yog ib hom qe ntshav dawb pom nyob rau hauv tib neeg cov ntshav thiab tsim nyob rau hauv feem ntau nyob rau hauv thawj thiab theem nrab lymphoid kab mob. Lub hauv paus tseem ceeb muaj xws li thymus thiab cov pob txha pob txha, thaum cov kab mob hauv nruab nrab muaj xws li cov poov xab, Cov neeg them nyiaj thaj ua rau pom hauv plab hnyuv, tonsils thiab adenoids, thiab cov qog nqaij hlav thiab cov nodules pom thoob plaws lub cev. Kev loj hlob ntawm lymphocyte muaj peb lub hlwb theem xws li; lymphoblast, prolymphocyte thiab mature lymphocyte. Lub lymphocyte mature muaj ob hom; me thiab loj lymphocytes. Qhov loj ntawm cov lymphocyte me me yog li 6 txog 9 µm thiab cov cell loj yog li 17 txog 20 µm. Cells muaj puag ncig-rau-oval zoo li tus nucleus nrog los yog tsis muaj indentation. Tsis muaj nucleoli pom nyob rau hauv lub nucleus. Kev loj hlob tshwm sim nyob rau hauv ob qhov chaw (a) hauv thymus, qhov twg T lymphocytes tsim, thiab (b) hauv cov qog nqaij hlav, qhov B lymphocytes raug tsim. Tus nqi ntawm lymphocytes nyob rau hauv cov ntshav peripheral sib txawv raws li hnub nyoog ntawm cov tib neeg. Feem ntau cov menyuam yaus hnub nyoog qis dua plaub xyoos muaj cov lymphocyte ntau dua li cov neeg laus. Lymphocyte yog ib qho tseem ceeb los tswj lub cell mediated tiv thaiv kab mob thiab humoral tiv thaiv nyob rau hauv lub cev.
YLymphoblast yog dab tsi?
Lymphoblast yog thawj lub xovtooj ntawm tes ntawm kev loj hlob ntawm lymphocyte paub tab. Cov cell no yog me me-rau-nruab nrab me me nrog kwv yees li 10-18 µm inch. Lub nucleus ntawm lymphoblast yog puag ncig-rau-oval zoo li tus thiab nws muaj xoob ntim chromatin thiab 1-2 nucleoli. Lub nucleus ntawm lymphoblast yog loj loj thiab nyob li ntawm 80% ntawm cov cell tag nrho ntawm tes. Lub cytoplasm ntawm lymphoblast yog agranular thiab muaj basophilia. Thaum lymphoblast hloov mus rau theem tom ntej ntawm tes; prolymphocyte, chromatin nyob rau hauv lub nucleus tau txais me ntsis condensed thaum txo cov nucleoli prominence.
Qhov txawv ntawm Lymphocyte thiab Lymphoblast yog dab tsi?
• Lymphoblast yog thawj lub xovtooj ntawm tes uas tuaj yeem txheeb xyuas thaum lub sijhawm kev loj hlob ntawm lymphocyte.
• Thaum lub sijhawm maturation, lymphoblast hloov mus rau prolymphocyte. Thaum cov prolymphocyte raug tsim, nws yog thaum kawg matured rau hauv lymphocyte.
• Qhov loj ntawm lymphoblast nyob ib ncig ntawm 10-18 µm whereas ntawm cov lymphocyte mature yog nyob ib ncig ntawm 17-20 µm.
• Nuclear-cytoplasmic ratio ntawm lymphoblast yog 4: 1, whereas ntawm lymphocyte yog 2: 1.
• cov lymphocytes paub tab tsis muaj nucleoli thaum lymphoblast muaj 1-2 nucleoli.
• Chromatin hauv lymphocytes yog ntom thiab clumped, tsis zoo li cov chromatin hauv lymphoblast.
• Tsis muaj granules nyob rau hauv cytoplasm ntawm lymphoblast, thaum ob peb azurophilic granules yuav pom nyob rau hauv lymphocytes.
• Thaum stained, lymphoblast cytoplasm hloov xim nruab nrab xiav nrog tsaus-xiav ciam teb, whereas lymphocyte cytoplasm tig mus rau lub teeb xiav.
