Wake wazibuza ukuthi kukhona yini amangqamuzana 'ahlekisayo' angaphakathi emizimbeni yethu angaba yinoma yini? Okungukuthi, amangqamuzana akhethekile angaba yiseli legazi, iseli lamathambo, noma iseli lemisipha uma kudingeka. Lawo maseli yilokho esikubiza ngokuthi amaseli okuqala . Lawa amabhlogo ayisisekelo emizimbeni yethu. Angenza amakhophi awo. Yingakho singalokothi siphelelwe yilawa maseli emizimbeni yethu. Futhi, lawa maseli okuqala asiza ekulungiseni izicubu emizimbeni yethu uma zonakele.
Kalula nje, zingaki izinhlobo zamaseli okuqala akhona?
Uma sibheka amaseli okuqala asemizimbeni yethu kanye nalawo adalwe emalabhorethri ngabacwaningi bezokwelapha, singakhuluma ngezinhlobo ezintathu eziyinhloko. Lezi zibaluleke kakhulu, ngakho ake sizibheke ngemininingwane ethe xaxa.
| Uhlobo lweseli lesiqu | Kwenzekani ngalokhu? |
|---|---|
| Amaseli Esiqu Se-Embryonic | Lezi yizindawo lapho sonke siqala khona ukuphila kwethu. Lawa maseli akhona embungwini owakheka lapho kuhlangana isidoda neqanda. Afana nezitini zokuqala esakhiweni. Lawa maseli angaba yinoma yiluphi uhlobo lweseli emzimbeni wethu. Lawa maseli embungwini anekhono lokwenza izinhlobo ezingaphezu kuka-200 zamaseli emzimbeni wethu. |
| Amaseli Esiqu Abadala | Lawa maseli atholakala ezicutshini ezahlukahlukene emzimbeni wakho. Umsebenzi wawo oyinhloko ukufaka esikhundleni samaseli alimele nokwenza amaseli amasha nokulungisa izicubu. Isibonelo, amaseli okuqala e-hematopoietic emnkantsheni wamathambo agcina amaseli ethu egazi kanye nesistimu yomzimba yokuzivikela. Amaseli okuqala e-Mesenchymal , atholakala ezicutshini ezahlukahlukene, anakekela izinto ezifana namathambo, i-cartilage, imisipha, namafutha. |
| Amaseli E-Pluripotent Stem Cells (ama-iPSC) Akhiqizwe Nge-Induced Pluripotent Stem Cells (ama-iPSC) | Lawa amaseli akhethekile enziwa elabhorethri. Abacwaningi bathatha amaseli okuqala amadala anikelwe bese bewaguqula ukuze asebenze njengamaseli okuqala e-embryonic. Lokho kusho ukuthi angaba yinoma yiluphi uhlobo lweseli. Lokhu kuyintuthuko enkulu kwezokwelapha. |
Ngakho-ke yiziphi izinzuzo ezinikezwa yila maseli okuqala?
Amaseli e-stem awawona nje amabhlogo okwakha imizimba yethu. Abaluleke kakhulu kubacwaningi bezokwelapha. Kunezizathu eziningana zalokho.
- Qonda ukuthi izifo zikhula kanjani: Abacwaningi bangakhulisa amaseli okuqala elabhorethri futhi bawabukele eshintsha, okungabasiza baqonde ukuthi izifo ezithile zikhula kanjani ezicutshini nasezithweni ezithile zomzimba.
- Thola izindlela zokwelapha ezintsha: Ucwaningo lwenziwa kuma-stem cell, alungisa noma avuselele izinhlobo ezithile zamaseli, njengamaseli egazi noma amaseli ethambo. Kunethemba elikhulu lokuthi lolu cwaningo luzoholela ezindleleni ezintsha zokwelapha izifo.
- Hlola imithi emisha: Ngaphambi kokunikeza abantu umuthi omusha, kusetshenziswa amaseli okuqala alungiselelwe ngokukhethekile ukuqinisekisa ukuthi uphephile futhi uyasebenza.
Kalula nje, ama-stem cell ayithuluzi elimangalisayo elingasisiza ukuthola izimbangela zezifo nokuthola ukwelashwa kwazo.
Siwathola kanjani la maseli okuqala ukuze sicwaningwe?
Kunezindlela eziningana zokuthola la maseli abalulekile ocwaningo, konke okwenziwa ngaphansi kwemithetho eqinile kanye nokuziphatha.
- Kusukela ezicutshini zomuntu ezinikelwe (eziqukethe amaseli okuqala abantu abadala).
- Kusukela egazini elivela entanjeni yesisu elikhishwa ngemva kokuzalwa komntwana (lawa aqukethe amaseli okuqala akha igazi).
- Kusukela kuma-embryo asetshenziselwa ukuchumisa i-In Vitro (IVF), nakulawo alondolozwa futhi anikelwe ocwaningweni.
- Kusukela kumaseli ``(iPSCs)`` alungiselelwe ngokukhethekile elabhorethri.
Yiziphi izifo ezisetshenziswayo njengamanje yi-Stem Cell Therapy?
Ukwelashwa ngamaseli e-stem kuseyinkambu ethuthuka ngokushesha, kodwa kakade isetshenziswa ngempumelelo kwezinye izimo zezokwelapha. Ake sibheke ukuthi ziyini.
| Isimo sezokwelapha | Indlela yokwelapha |
|---|---|
| Umdlavuza Wegazi | Ukufakelwa amaseli e-stem kuyindlela enkulu yokwelapha umdlavuza wegazi njenge- leukemia , i-multiple myeloma, kanye nezinye izinhlobo ze-lymphoma (i-non-Hodgkin lymphoma) . Kule nqubo, kunikezwa amaseli e-stem aphilile ukuze athathe indawo yomnkantsha wethambo wesiguli owonakele. |
| Izinkinga Zegazi | Ukufakelwa kwamaseli e-stem kusetshenziswa futhi njengokwelapha izinkinga zegazi, njengezinhlobo ezithile ze -anemia . |
| Amathambo Aphukile | Izingxenyana zamathambo, ezenziwe ngamaseli e-mesenchymal stem cell (MSCs) anikelwe kanye nezinye izinto, zisetshenziselwa ukwelapha ukuphuka okukhulu. |
Ngaphezu kwalokho, abacwaningi baqhubeka befunda ngamathuba okusebenzisa ama-MSC njengokwelapha i-osteoarthritis, isifo samalunga esiwohlokayo.
Ingabe amaseli ethu e-stem angonakala?
Yebo, ezinye izimo zezokwelapha zingalimaza amaseli okuqala emzimbeni wethu, ikakhulukazi amaseli okuqala akha igazi emnkantsheni wamathambo. Isibonelo:
- I-anemia ye-Aplastic
- I-Leukemia
- I-myeloma eminingi
- Izinkinga ze-Myeloproliferative
Lezi zifo zithinta umongo wamathambo, zinciphisa ikhono lawo lokukhiqiza amangqamuzana egazi anempilo.
Singakwazi yini ukwandisa amaseli ethu e-stem ngokwemvelo?
Lona umbuzo abantu abaningi abawubuzayo. Ucwaningo luyaqhubeka ukuze kutholakale ukuthi ukuthatha amavithamini athile kungasiza yini umzimba ukuthi wakhe amaseli e-stem amaningi. Kodwa-ke, akukabikho siphetho esiqinisekile okwamanje. Ngakho-ke, ungaphuzi amavithamini noma izithasiselo ocabanga ukuthi zizokwandisa amaseli e-stem ngaphandle kokubonisana nodokotela wakho.
Imizimba yethu iyindalo emangalisayo eyenziwe ngamaseli ayizigidigidi. Kulawo maseli, amaseli okuqala yiwona kuphela uhlobo lweseli olungenza amakhophi angenamkhawulo futhi lube ezinye izinhlobo zamaseli. Yingakho ebaluleke kangaka. Njengoba kakade esetshenziswa njengokwelashwa okusindisa impilo kwezifo ezifana nomdlavuza wegazi, odokotela bakholelwa ukuthi amaseli okuqala azoba yisihluthulelo sokwelapha ezinye izifo eziningi esikhathini esizayo.
Umlayezo Wokuya Nawe Ekhaya
- Amaseli e-stem angamaseli 'ayinhloko' angaba yinoma yiluphi uhlobo lweseli emzimbeni wethu.
- Lokhu kubalulekile ekukhuleni komzimba, ekulungiseni izicubu ezonakele, nasekugcinweni kwempilo.
- Ukwelashwa ngamaseli e-stem okwamanje kusetshenziswa ngempumelelo ekwelapheni umdlavuza wegazi, izifo zegazi, kanye nokuqhekeka kwamathambo.
- Ngokuthuthuka kwesayensi yezokwelapha, kunethemba elikhulu lokuthi amaseli okuqala azokwazi ukwelapha izifo eziningi esikhathini esizayo.
- Uma unemibuzo mayelana nokwelashwa kwamaseli e-stem, hlala uthintana nochwepheshe wezokwelapha ofanelekayo, njengodokotela wakho. Ungathembeli olwazini olungaqinisekisiwe olutholakala ku-inthanethi noma kwenye indawo.
