Oboolyawo owuliddeko ekigambo "Stem Cell". Waliwo okwogera kungi ku kino ng’ekiyinza okugonjoola endwadde nnyingi ezikyali enzibu okuwonya, gamba nga ssukaali, obulwadde bwa Parkinson, n’okusannyalala. Kale katutunuulire obutoffaali buno obusibuka mu butuufu kye buli, emigaso gye buyinza okutuwa, era lwaki waliwo okukubaganya ebirowoozo okunene bwe butyo mu nsi.
Obutoffaali buno obusibuka mu mubiri kye ki?
Mu ngeri ennyangu, obutoffaali obusibuka mu mubiri buba ng’ekikuta ky’ebbumba ekitaliiko kifaananyi. Tusobola okutwala ekikuta kino eky’ebbumba ne tukibumba mu kintu kyonna kye twagala, gamba ng’ekibya oba ekibumbe. Bw’etyo obutoffaali buno obusibuka mu mubiri bwe buyinza okufuuka ekika kyonna eky’obutoffaali obw’enjawulo mu mubiri gwaffe. Zino ze "master cells" mu mubiri gwaffe.
Kwe kugamba, ekika kino kye kimu eky’obutoffaali obusibuka mu mubiri, okusinziira ku bwetaavu, kisobola okufuuka obutoffaali bw’olususu , obutoffaali bw’ebinywa by’omutima , obutoffaali bw’obusimu bw’obwongo , oba obutoffaali obukola insulini mu kyenda . Olw’obusobozi buno obw’ekitalo, bannassaayansi balina essuubi ddene ku kino.
Obutoffaali buno tubuggya wa?
Waliwo enkola bbiri enkulu ez’okufuna obutoffaali obusibuka mu mubiri.
1. Okuva ku mubiri gw’omuntu omukulu: Mu bitundu by’omubiri gwaffe ebimu okugeza mu busimu bw’amagumba , waliwo obutoffaali buno obutono. Bino bivaamu ebintu ng’obutoffaali obupya obw’omusaayi. Zino ziyitibwa obutoffaali obusibuka mu bantu abakulu.
2. Okuva mu Embryos: Eno y’enkola esinga okwogerwako n’okukaayana. Kwe kugamba, obutoffaali buno bufunibwa okuva mu nkwaso, nga guno gwe mutendera ogusooka mu bulamu bw’omuntu. Bino bitera okuggyibwa mu nkwaso ezirina okuggyibwa mu bafumbo abagenda mu bujjanjabi bw’okuzaala mu kisenge (IVF) , nga bakkirizza.
Emirundi mingi, abafumbo abaagala okuzaala bwe bayita mu bujjanjabi bwa IVF, embuto eziwera zitondebwawo okwongera ku buwanguzi. Oluvannyuma lw’okuteekebwa emu oba bbiri ku zo mu nnabaana wa maama, embuto ezisigaddewo oluusi zisaanawo. Mu nsi nnyingi, embuto ezandibadde zisuuliddwa mu ngeri yonna ze zaakkirizibwa okukozesebwa mu kunoonyereza kuno.
Migaso ki egyewuunyisa egya tekinologiya ono?
Okay, kati ka tulabe emigaso gye tuyinza okufuna mu butoffaali buno obw’ekyewuunyo. Kuba akafaananyi ng’obutoffaali obuli mu kitundu ky’omubiri gwaffe bufudde olw’obulwadde. Watya singa tusobola okukyusa obutoffaali obwo obufu ne tussaamu obutoffaali obupya, obulamu ne tubusimbuliza mu kifo ekyo? Ekyo kye kigendererwa ekikulu eky’okunoonyereza ku butoffaali obusibuka.
| Embeera y’obujjanjabi | Ekigonjoola obutoffaali obusibuka mu mubiri kye busobola okuwa |
|---|---|
| Ssukaali (Obulwadde bwa sukaali) . | Ssukaali abaawo ng’obutoffaali mu lubuto obukola insulini busaanyiziddwaawo. Mu kifo ky’ekyo, obutoffaali obupya obukola insulini busobola okutondebwa mu laboratory ne bufukibwa mu mubiri. |
| Obulwadde bwa Parkinson | Obulwadde buno buva ku kufa kw’obutoffaali mu bwongo obukola eddagala eriyitibwa dopamine. Mu kifo ky’ekyo, obutoffaali obupya obukola dopamine busobola okutondebwawo ne busimbibwa mu bwongo. |
| Okusannyalala | Kisoboka okugezaako okuzzaawo emirimu egyabuze ng’ozzaawo obutoffaali bw’obusimu obwonooneddwa mu kabenje. |
| Obulwadde bw'omutima | Obutoffaali buno busobola okukozesebwa okuzza obuggya ebitundu by’ebinywa by’omutima ebyonooneddwa obulwadde bw’omutima. |
Naye... waliwo ensonga ennene ey'empisa ku kino.
Tekinologiya ono ne bw’aba mulungi atya, waliwo okusika omuguwa n’okukubaganya ebirowoozo kungi ku ndowooza y’okufuna obutoffaali buno okuva mu nkwaso. Waliwo endowooza bbiri enkulu ku nsonga eno.
Oludda olumu lugamba nti kino kiyinza okutaasa obulamu bw’enkumi n’enkumi z’abantu. Ate kino kikozesa embuto ezandibadde zisaanawo. N’olwekyo bannassaayansi n’abanoonyereza bangi bakkiriza nti tewali kibi mu kukolera bantu birungi. Kino bakiraba ng’ekintu kya ssaayansi ekiyinza okutaasa obulamu.
Naye oludda olulala , naddala ebibiina by’eddiini n’abo abafaayo ennyo ku mpisa, lunyumya emboozi ya njawulo ddala. Ensonga yaabwe eri nti embuto, ne bw’eba ntono etya, y’entandikwa y’obulamu bw’omuntu. N’olwekyo, okusaanyaawo obulamu obwo olw’okunoonyereza kikyamu. Okusinziira ku bo, kino kitondekawo "obulamu bw'abantu obusuuliddwa."
Mu ngeri ennyangu, ekibuuzo kyabwe kiri nti, ‘Mu mpisa kituufu okusaanyaawo obulamu bw’omuntu omulala (ne bwe kiba omwana ali mu lubuto) okusobola okutaasa obulamu bw’omuntu omu?’
Embeera n’ebiseera by’ensi eby’omu maaso
Olw’okusika omuguwa kuno, amawanga agamu gataddewo amateeka amakakali ku kunoonyereza kuno. Amawanga amalala nga Bungereza gakkirizza okunoonyereza kuno okugenda mu maaso nga kuliko obukwakkulizo. Kino kitera okuleka abanoonyereza nga balonzalonza. Kubanga okunoonyereza okukolebwa ku ssente ennyingi kuyinza okuyimirira mu bwangu olw’okusalawo kw’ebyobufuzi.
Wabula abalwadde n’ab’omu maka gaabwe abatawaanyizibwa endwadde nga sukaali ne Parkinson balina essuubi ddene nti okunoonyereza kuno kugenda mu maaso mangu. Eno y’ensonga lwaki bulijjo bayimusa amaloboozi gaabwe okuwagira okunoonyereza kuno.
Kino kitegeeza kunnyonnyola kwokka ku bukodyo. Era tukujjukiza bulijjo okwogera n’omusawo w’amaka go ku mbeera yonna ey’obujjanjabi gy’oyinza okuba nayo.
Obubaka Obutwala Awaka
- Obutoffaali obusibuka (stem cells) kika kya njawulo eky’obutoffaali obusookerwako obuyinza okufuuka obutoffaali bwonna mu mubiri gwaffe.
- Waliwo essuubi ddene nti bino bijja kusobola okuwonya endwadde nga sukaali n’okusannyalala.
- Olw’okuba bino bifunibwa okuva mu nkwaso, waliwo okukubaganya ebirowoozo okunene ennyo ku mpisa wakati w’abo abakitwala nti ‘ekisaanyaawo obulamu bw’omuntu’ n’abo abakitwala nti ‘okukola obulungi n’enkwaso esuuliddwa’.
- Guno mulamwa muzibu nnyo. Okuzuula enzikiriziganya wakati w’enkulaakulana mu bya ssaayansi n’empisa z’abantu kye kizibu ekisinga obunene mu biseera eby’omu maaso.
