Koj puas tau xav txog seb puas muaj cov hlwb 'joker' hauv peb lub cev uas muaj peev xwm ua tau txhua yam? Uas yog, cov hlwb tshwj xeeb uas tuaj yeem ua tau cov hlwb ntshav, cov hlwb pob txha, lossis cov hlwb nqaij thaum xav tau. Cov hlwb ntawd yog yam peb hu ua cov hlwb noob . Cov no yog cov khoom tseem ceeb ntawm peb lub cev. Lawv tuaj yeem ua cov ntawv theej ntawm lawv tus kheej. Yog vim li ntawd peb thiaj li tsis tas cov hlwb no hauv peb lub cev. Tsis tas li ntawd, cov hlwb noob no pab kho cov nqaij hauv peb lub cev thaum lawv puas tsuaj.
Hais yooj yim xwb, muaj pes tsawg hom stem cell?
Thaum peb saib cov noob hlwb uas nyob hauv peb lub cev thiab cov uas cov kws tshawb fawb tsim los ntawm cov chaw soj nstuam, peb tuaj yeem tham txog peb hom tseem ceeb. Cov no tseem ceeb heev, yog li cia peb saib lawv kom meej me ntsis.
| Hom hlwb qia | Muaj dab tsi tshwm sim rau qhov no? |
|---|---|
| Cov Qog Nqaij Hlav Embryonic | Cov no yog cov chaw uas peb txhua tus pib peb lub neej. Cov hlwb no nyob hauv lub embryo uas tsim thaum cov phev thiab qe los ua ke. Lawv zoo li thawj lub cib hauv lub tsev. Cov hlwb no tuaj yeem dhau los ua txhua hom hlwb hauv peb lub cev. Cov hlwb embryonic no muaj peev xwm tsim ntau dua 200 hom hlwb hauv peb lub cev. |
| Cov Qog Ntshav Laus | Cov hlwb no pom muaj nyob rau hauv ntau yam nqaij hauv koj lub cev. Lawv lub luag haujlwm tseem ceeb yog hloov cov hlwb uas puas lawm thiab tsim cov hlwb tshiab thiab kho cov hlwb. Piv txwv li, cov hlwb hematopoietic hauv cov pob txha pob txha tswj peb cov hlwb ntshav thiab lub cev tiv thaiv kab mob. Cov hlwb mesenchymal , uas pom muaj nyob rau hauv ntau yam nqaij, saib xyuas cov khoom xws li pob txha, pob txha mos, cov leeg, thiab cov rog. |
| Cov Pluripotent Stem Cells (iPSCs) uas raug tsim los | Cov no yog cov hlwb tshwj xeeb uas tau tsim nyob rau hauv chav kuaj. Cov kws tshawb fawb tau coj cov hlwb laus uas tau pub dawb thiab hloov kho lawv kom ua haujlwm zoo li cov hlwb menyuam hauv plab. Qhov ntawd txhais tau tias lawv tuaj yeem dhau los ua txhua hom hlwb. Qhov no yog ib qho kev tshawb pom loj hauv kev kho mob. |
Yog li cov stem cell no muab cov txiaj ntsig dab tsi rau peb?
Cov noob hlwb tsis yog cov khoom siv tseem ceeb rau peb lub cev xwb. Lawv tseem ceeb heev rau cov kws tshawb fawb txog kev kho mob. Muaj ntau yam ua rau qhov ntawd.
- To taub txog seb cov kab mob loj hlob li cas: Cov kws tshawb fawb tuaj yeem cog cov noob hlwb hauv chav kuaj thiab saib lawv hloov pauv, uas tuaj yeem pab lawv nkag siab txog qee yam kab mob loj hlob li cas hauv cov nqaij thiab cov kabmob tshwj xeeb.
- Tshawb nrhiav kev kho mob tshiab: Kev tshawb fawb tab tom ua rau cov hlwb noob, uas kho lossis rov tsim cov hlwb tshwj xeeb, xws li cov hlwb ntshav lossis cov hlwb pob txha. Muaj kev cia siab tias kev tshawb fawb no yuav ua rau muaj txoj hauv kev tshiab los kho cov kab mob.
- Sim cov tshuaj tshiab: Ua ntej muab cov tshuaj tshiab rau tib neeg, cov hlwb noob uas tau npaj tshwj xeeb raug siv los xyuas kom meej tias nws muaj kev nyab xeeb thiab ua haujlwm.
Hais yooj yim xwb, cov hlwb noob (stem cells) yog ib qho cuab yeej zoo heev uas tuaj yeem pab peb nrhiav cov ua rau muaj kab mob thiab nrhiav kev kho rau lawv.
Peb yuav ua li cas thiaj tau cov stem cell no los tshawb nrhiav?
Muaj ntau txoj hauv kev kom tau txais cov hlwb muaj nqis no rau kev tshawb fawb, txhua yam uas tau ua raws li cov cai thiab kev coj ncaj ncees nruj heev.
- Los ntawm cov nqaij ntawm tib neeg pub dawb (uas muaj cov hlwb laus).
- Los ntawm cov ntshav ntawm txoj hlab ntaws uas raug rho tawm tom qab yug tus me nyuam (cov no muaj cov hlwb tsim cov ntshav).
- Los ntawm cov noob qes uas siv rau In Vitro Fertilization (IVF), thiab los ntawm cov uas tau khaws cia thiab pub rau kev tshawb fawb.
- Los ntawm cov hlwb "(iPSCs)" uas tau npaj tshwj xeeb hauv chav kuaj mob.
Tam sim no siv Stem Cell Therapy rau cov kab mob twg?
Kev kho mob los ntawm cov noob hlwb (stem cell therapy) tseem yog ib qho kev tshawb fawb uas tab tom loj hlob sai heev, tab sis nws twb tau siv tau zoo rau qee yam mob. Cia peb saib seb lawv yog dab tsi.
| Mob nkeeg | Yuav kho li cas |
|---|---|
| Mob qog ntshav | Kev hloov cov hlwb noob (stem cell transplants) yog ib txoj kev kho mob loj rau cov mob qog ntshav xws li mob leukemia , mob multiple myeloma, thiab qee hom lymphoma (non-Hodgkin lymphoma) . Hauv txoj kev kho mob no, cov hlwb noob noj qab nyob zoo raug muab los hloov cov pob txha uas puas lawm ntawm tus neeg mob. |
| Kev Mob Ntshav | Kev hloov cov noob hlwb kuj tseem siv los kho cov kab mob ntshav, xws li qee hom kab mob ntshav tsis txaus . |
| Pob Txha Tawg | Cov pob txha txuas, uas yog ua los ntawm cov hlwb mesenchymal stem cell (MSCs) pub dawb thiab lwm yam khoom siv, yog siv los kho qee qhov pob txha tawg hnyav. |
Tsis tas li ntawd xwb, cov kws tshawb nrhiav tab tom kawm ntxiv txog lub peev xwm ntawm kev siv MSCs ua kev kho mob rau osteoarthritis, uas yog ib qho kab mob sib koom ua ke.
Peb cov noob hlwb puas tuaj yeem raug puas tsuaj?
Yog lawm, qee yam mob nkeeg tuaj yeem ua rau cov hlwb hauv peb lub cev puas tsuaj, tshwj xeeb tshaj yog cov hlwb tsim cov ntshav hauv cov pob txha. Piv txwv li:
- Aplastic anemia
- Kab mob ntshav dawb (leukemia)
- ntau yam mob myeloma
- Cov kab mob Myeloproliferative
Cov kab mob no cuam tshuam rau cov pob txha pob txha, txo nws lub peev xwm los tsim cov qe ntshav noj qab haus huv.
Peb puas tuaj yeem ua kom peb cov stem cell ntau ntxiv raws li ntuj tsim?
Qhov no yog ib lo lus nug uas ntau tus neeg nug. Kev tshawb fawb tseem tab tom ua mus kom pom tias kev noj qee cov vitamins puas tuaj yeem pab lub cev tsim ntau cov stem cell. Txawm li cas los xij, tseem tsis tau muaj qhov xaus lus tseeb. Yog li ntawd, tsis txhob noj cov vitamins lossis cov tshuaj ntxiv uas koj xav tias yuav ua rau cov stem cell ntau ntxiv yam tsis tau sab laj nrog koj tus kws kho mob.
Peb lub cev yog ib qho kev tsim zoo kawg nkaus uas muaj ntau txhiab lab lub hlwb. Ntawm cov hlwb ntawd, cov hlwb qia yog tib hom hlwb uas tuaj yeem ua cov ntawv theej ntawm nws tus kheej thiab dhau los ua lwm hom hlwb. Yog vim li cas lawv thiaj muaj nqis heev. Twb tau siv los ua kev kho mob cawm siav rau cov kab mob xws li mob qog ntshav, cov kws kho mob ntseeg tias cov hlwb qia yuav yog qhov tseem ceeb rau kev kho ntau yam kab mob yav tom ntej.
Cov Lus Qhia Txog Kev Coj Mus Tsev
- Cov hlwb qia (stem cells) yog cov hlwb 'tswv' ('master' cells) uas tuaj yeem dhau los ua txhua hom hlwb hauv peb lub cev.
- Cov no yog qhov tseem ceeb rau lub cev txoj kev loj hlob, kho cov nqaij uas puas lawm, thiab kev saib xyuas kev noj qab haus huv.
- Kev kho mob los ntawm cov noob hlwb tam sim no siv tau zoo rau cov mob qog ntshav, cov kab mob ntshav, thiab qee cov pob txha tawg.
- Nrog kev nce qib ntawm kev tshawb fawb kho mob, muaj kev cia siab tias cov hlwb noob yuav muaj peev xwm kho tau ntau yam kab mob ntxiv yav tom ntej.
- Yog koj muaj lus nug txog kev kho mob stem cell, nrog ib tus kws kho mob uas tsim nyog tham, xws li koj tus kws kho mob. Tsis txhob cia siab rau cov ntaub ntawv tsis tau lees paub uas pom hauv Is Taws Nem lossis lwm qhov chaw.
