Qhov sib txawv tseem ceeb ntawm HeLa Cells thiab cov qog nqaij hlav cancer yog HeLa hlwb yog cov hlwb tsis txawj tuag tau los ntawm cov qog nqaij hlav qog noj ntshav feem ntau siv hauv kev tshawb fawb, thaum cov qog nqaij hlav cancer yog cov hlwb tsis txawj tuag uas tuaj yeem faib raws li lawv cov keeb kwm hauv tib neeg lub cev., xws li cov qog nqaij hlav qog nqaij hlav epithelial, cov qog nqaij hlav qog ntshav, lub cev tiv thaiv kab mob qog noj ntshav, cov qog nqaij hlav qog noj ntshav, cov hlab ntsha hauv nruab nrab ntawm lub paj hlwb lossis cov hlwb qog nqaij hlav mesothelium.
mob qog noj ntshav yog ib yam mob uas qee lub cev cov hlwb loj hlob tsis tuaj yeem tswj tau thiab kis mus rau lwm qhov ntawm tib neeg lub cev. Nws tuaj yeem pib yuav luag txhua qhov chaw hauv tib neeg lub cev. Cov qog nqaij hlav cancer zoo tsis cuam tshuam cov ntaub so ntswg nyob ze. Tab sis cov qog nqaij hlav cancer tuaj yeem mus rau qhov chaw nyob deb ntawm lub cev los tsim cov qog tshiab. Cov qog nqaij hlav cancer tau piav qhia tias tsis txawj tuag thaum lawv tsis muaj hnub nyoog lossis tuag. HeLa hlwb thiab qog nqaij hlav cancer yog ob hom hlwb tsis txawj tuag.
HeLa Cells yog dab tsi?
HeLa hlwb yog cov hlwb tsis txawj tuag tau los ntawm cov qog nqaij hlav qog noj ntshav siv hauv kev tshawb fawb tshawb fawb. HeLa Cells yog cov laus tshaj plaws thiab feem ntau siv tib neeg cov xov tooj ntawm tes hauv kev tshawb fawb. Nws tau muab los thiab muaj npe tom qab ib tug poj niam hu ua Henrietta Lacks, 31-xyoo-laus African-Asmeskas niam ntawm tsib tus uas tuag los ntawm kev mob qog noj ntshav hauv xyoo 1951. Cov hlwb no yog tsim los ntawm cov qog nqaij hlav qog noj ntshav uas coj los ntawm Lacks. HeLa hlwb tau pom tias muaj qhov ruaj khov thiab muaj txiaj ntsig zoo. Yog li, qhov no tso cai rau nws siv dav hauv kev tshawb fawb.
Daim duab 01: HeLa Cells
Ib qhov kev tsis sib haum xeeb tau tshwm sim thaum lub hlwb ntawm Henrietta Lacks raug coj mus yam tsis tau nws tso cai, uas yog ib qho kev coj ua hauv Tebchaws Meskas thaum lub sijhawm ntawd. Ntxiv mus, cell biologist George Otto Gey tau tsim cov kab ntawm tes tom qab nws pom tias cov hlwb los ntawm Lack's qog muaj sia nyob ntev dua piv rau tib neeg lub hlwb yav dhau los. HeLa hlwb tau ua tiav siv ntau yam kev tshawb fawb, suav nrog kev tshem tawm cov kab mob polio, kab mob virology, mob qog noj ntshav, noob caj noob ces, thiab chaw microbiology.
Cov Kab Mob Cancer yog dab tsi?
Cov qog nqaij hlav cancer yog cov hlwb tsis txawj tuag uas faib tsis tu ncua. Cov hlwb no feem ntau tsim cov qog nqaij hlav lossis dej nyab cov ntshav nrog cov hlwb txawv txav. Lawv tuaj yeem raug cais raws li lawv lub hauv paus hauv tib neeg lub cev, xws li cov qog nqaij hlav qog nqaij hlav epithelial, cov qog ntshav qog ntshav, lub cev tiv thaiv kab mob qog noj ntshav, cov qog nqaij hlav qog noj ntshav, cov hlab ntsha hauv nruab nrab cov hlab ntsha hlwb, lossis cov hlwb qog nqaij hlav mesothelial. Cov qog nqaij hlav cancer txuas ntxiv tsim cov ntawv luam thiab tseem tuaj yeem kis tau los ntawm ib feem ntawm lub cev mus rau lwm qhov. Cov txheej txheem ntawm kev sib kis no hu ua metastasis.
Daim duab 02: Cov Kab Mob Cancer
Cov kab mob qog noj ntshav sib txawv yog siv rau kev kuaj mob txhawm rau txhawm rau txheeb xyuas ntau hom mob qog noj ntshav hauv kev teeb tsa kho mob. Tsis tas li ntawd, cov kws tshawb fawb tsis ntev los no tau tshawb pom ib qho molecule nyob rau saum npoo ntawm cov qog uas zoo li txhawb cov tshuaj tiv thaiv los ntawm kev hloov cov qog hlwb rov qab mus rau hauv lub cev zoo li lub cev. Txawm li cas los xij, ntau yam tshuaj uas twb muaj lawm (bortezomib) tuaj yeem tawm tsam txoj hauv kev no. Cov tshuaj no rov rhiab cov qog los kho.
Dab tsi zoo sib xws ntawm HeLa Cells thiab Cancer Cells?
- HeLa hlwb thiab qog nqaij hlav cancer yog ob hom hlwb tsis txawj tuag.
- Ob leeg qhia kev loj hlob tsis tuaj yeem tswj tau.
- Cov no qhia metastasis ntws.
- Lub enzyme telomerase yog siv los txuas ntxiv lub neej ntawm ob qho tib si.
Qhov txawv ntawm HeLa Cells thiab Cancer Cells yog dab tsi?
HeLa hlwb yog cov hlwb tsis txawj tuag tau los ntawm cov qog nqaij hlav qog noj ntshav uas siv dav hauv kev tshawb fawb, thaum cov qog nqaij hlav cancer yog cov hlwb tsis txawj tuag uas tuaj yeem faib raws li lawv cov keeb kwm hauv tib neeg lub cev. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm HeLa hlwb thiab cov qog nqaij hlav cancer. Tsis tas li ntawd, HeLa hlwb tau siv dav hauv kev tshawb fawb tshawb fawb, thaum cov qog nqaij hlav cancer feem ntau yog siv rau hauv kev kuaj mob ntawm cov qog nqaij hlav sib txawv hauv kev kho mob.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm HeLa hlwb thiab cov qog nqaij hlav qog nqaij hlav hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – HeLa Cells vs Cancer Cells
HeLa hlwb thiab qog nqaij hlav cancer yog ob hom hlwb uas tsis txawj tuag los ntawm tib neeg. Cov hlwb HeLa yog cov hlwb tsis txawj tuag tau los ntawm cov qog nqaij hlav qog noj ntshav feem ntau siv hauv kev tshawb fawb tshawb fawb, thaum cov qog nqaij hlav cancer yog cov hlwb tsis txawj tuag uas tuaj yeem faib raws li lawv lub hauv paus hauv tib neeg lub cev, xws li cov qog nqaij hlav qog nqaij hlav, cov qog ntshav qog ntshav, lub cev tiv thaiv kab mob qog noj ntshav, connective cov ntaub so ntswg cancer hlwb, central paj hlwb hlwb hlwb los yog mesothelium cancer hlwb. Yog li, qhov no yog qhov txawv ntawm HeLa hlwb thiab qog nqaij hlav cancer.
