Qhov Tseem Ceeb Qhov txawv - Umbilical Cord Stem Cells vs Embryonic Stem Cells
qia hlwb yog cov hlwb tsis paub tab ntawm ntau cov kab mob. Lawv muaj peev xwm faib thiab sib txawv rau hauv cov hlwb lossis cov ntaub so ntswg. Cov qia hlwb tuaj yeem sib txawv ntawm lwm hom cell vim muaj ntau yam xws li rov ua dua lawv tus kheej los ntawm kev faib tawm ntawm tes, tshwj xeeb rau hauv cov ntaub so ntswg lossis cov kabmob ua haujlwm tshwj xeeb, thiab lwm yam. Cov yam ntxwv ntawm qia hlwb no yog cov cuab yeej tseem ceeb hauv cov ntaub so ntswg engineering thiab kho kab mob. Lawv muaj peev xwm biotechnological thiab. Umbilical cord stem cells thiab embryonic stem cells yog ob hom qia hlwb siv hauv kev kho kab mob thiab biotechnology. Umbilical cord stem cells yog cov hlwb tsis sib xws uas pom hauv cov ntshav thiab cov ntaub so ntswg ntawm txoj hlab ntaws. Cov kab mob embryonic qia hlwb yog cov hlwb tsis sib xws hauv tsib mus rau yim hnub qub hauv vitro fertilized embryo. Qhov sib txawv tseem ceeb ntawm txoj hlab ntaws caj dab thiab cov kab mob embryonic qia hlwb yog tias umbilical qaum qia hlwb muaj ntau lub zog thaum embryogenic qia hlwb yog pluripotent.
Umbilical Cord Stem Cells yog dab tsi?
Cov qaum qaum yog qhov hloov pauv tau zoo li cov qauv uas txuas tib neeg fetus mus rau qhov placenta ntawm leej niam. Thaum lub sij hawm cev xeeb tub, cov khoom noj uas muaj oxygenated ntshav hloov los ntawm cov placenta mus rau tus menyuam thiab cov khoom noj depleted deoxygenated ntshav hloov ntawm tus menyuam mus rau lub placenta ntawm txoj hlab ntaws. Txoj hlab ntaws yog tsim los ntawm cov ntaub so ntswg thiab ntshav. Ob leeg cov ntaub so ntswg thiab cov ntshav muaj cov hlwb uas tsis muaj qhov sib txawv hu ua cord tissue stem cells thiab cord blood stem cells, ntsig txog. Lawv yog ob hom tseem ceeb ntawm umbilical qaum qia hlwb. Umbilical qia hlwb yog cov hlwb muaj zog nrog lub peev xwm zoo tshaj plaws los tsim cov ntaub so ntswg tshiab. Li no, lawv thiaj li nrov ua cov tshuaj kho mob (cov khoom kho tus kheej) rau ntau tshaj 80 tus kab mob paub hauv tib neeg.
Umbilical stem cells raug suav hais tias yog qhov kho tau zoo rau cov kab mob hauv cov pob txha thiab cov kab mob hauv lub cev tsis ua haujlwm ntawm cov metabolism. Ib qho kev siv loj ntawm cov qia hlwb no yog cov ntaub so ntswg engineering. Umbilical cord stem cells muaj peev xwm faib cov cell loj heev thiab siv los kho thiab rov ua dua cov ntaub so ntswg puas.
Umbilical stem cell therapy yog siv rau ntau yam kab mob xws li leukemia, lymphoma, anemia, sickle cell anemia, beta thalassemia, mob hnyav ua ke tiv thaiv kab mob (SCID), mob ntshav liab aplasia, ntau yam myeloma, ntshav ntshav qog ntshav, ntshav. Cov kab mob proliferated, hurler syndrome, neeg yos hav zoov syndrome, ALD, Lesch-Nyhan syndrome, Osteopetrosis, qog nqaij hlav xws li neuroblastoma, retinoblastoma thiab medulloblastoma, thiab lwm yam.
Cov kab mob Umbilical stem cells tuaj yeem khaws cia los ntawm kev tso nyiaj ntawm cov hlab ntshav. Vim lawv muaj peev xwm kho tau zoo tshaj plaws thiab lub zog kho tau zoo, cov niam txiv zoo li khaws cia lawv cov menyuam mos txoj hlua caj dab qia hlwb rau kev siv tom qab.

Dab tsi yog embryonic Stem Cells?
Embryonic qia hlwb yog cov hlwb tsis txawv ntawm tib neeg embryo. Cov qia hlwb no muaj peev xwm faib tau sai thiab sib txawv rau ntau tshaj 200 hom cell hauv cov neeg laus. Yog li ntawd lawv yog hu ua pluripotent hlwb. Cov kab mob embryonic loj hlob feem ntau rau hauv peb txheej kab mob tseem ceeb hu ua ectoderm, endoderm, thiab mesoderm, uas tom qab sib txawv rau hauv tib neeg lub cev ntawm tes.
Cov kab mob embryonic, zoo li umbilical cord stem cells, yog siv los kho cov kab mob. Txawm li cas los xij, embryonic qia hlwb uas tsuas yog muab los ntawm cov embryo hauv vitro fertilized tsuas yog siv rau lub hom phiaj ntawd vim muaj teeb meem kev coj ncaj ncees ntsig txog lub embryo. Cov txheej txheem no tsuas yog txwv rau cov embryos tsim nyob rau hauv vitro thiab tshwj xeeb tshaj yog tsis yog rau cov qia hlwb tau los ntawm embryo tsim nyob rau hauv poj niam lub cev. Cov qia hlwb coj los ntawm ob peb hnub - cov embryo qub tau khaws cia hauv cov chaw soj nstuam raws li embryonic qia cell kab. Yog tias muaj cov xwm txheej zoo, nws muaj peev xwm tswj tau cov qia hlwb tsis sib xws hauv cov chaw sim.
Feem ntau, nws pom tseeb tias embryonic qia hlwb yog cov hlwb uas tsim txhua hom cell ntawm lub cev nrog rau cov leeg, paj hlwb, daim siab thiab ntau lwm cov hlwb. Yog tias cov kws tshawb fawb muaj peev xwm tswj tau lub chaw kuaj mob embryonic qia cell sib txawv tau zoo, lawv tuaj yeem siv cov hlwb los kho qee yam kab mob xws li ntshav qab zib, kev raug mob ntawm tus txha caj qaum, Duchenne's muscular dystrophy, kab mob plawv, thiab tsis pom kev thiab hnov lus, thiab lwm yam.

Summary – Umbilical Cord Stem Cells vs Embryonic Stem Cells
Umbilical stem cells thiab embryonic stem cells yog ob hom kab mob tseem ceeb. Umbilical cord stem cells muaj xws li ob qho tib si umbilical cord cov ntaub so ntswg thiab ntshav qia hlwb uas yog cov hlwb tsis txawv. Lawv tuaj yeem sib txawv rau ntau hom yog li lawv muaj ntau yam. Cov kab mob embryonic qia hlwb yog cov hlwb tsis txawv txav ntawm tsib mus rau yim hnub qub embryo tsim los ntawm hauv vitro fertilization. Lawv yog cov pluripotent thiab tuaj yeem tshwj xeeb rau ntau hom cell hauv tib neeg. Qhov no yog qhov txawv ntawm umbilical qaum qia hlwb thiab embryonic qia hlwb.
