Mwina mwamvapo mawu akuti "Stem Cell". Pali nkhani zambiri zokhudza izi ngati njira yothetsera matenda ambiri omwe akadali ovuta kuchiza, monga matenda a shuga, matenda a Parkinson, ndi ziwalo zopuwala. Tiyeni tiwone zomwe maselo oyambira awa ali, maubwino omwe angatipatse, komanso chifukwa chake pali mkangano waukulu wokhudza iwo padziko lonse lapansi.
Kodi maselo oyambira awa ndi chiyani?
Mwachidule, selo loyambira lili ngati dongo lopanda mawonekedwe. Tingatenge dongo ili ndikulipanga kukhala chilichonse chomwe tikufuna, monga mphika kapena chifaniziro. Umu ndi momwe maselo oyambira awa amatha kukhala mtundu uliwonse wa selo lapadera m'thupi lathu. Awa ndi "maselo apamwamba" m'thupi lathu.
Izi zikutanthauza kuti, mtundu womwewo wa selo loyambira, kutengera kufunikira kwake, ukhoza kusanduka selo la khungu , selo la minofu ya mtima , selo la mitsempha ya ubongo , kapena selo lopanga insulin mu kapamba . Chifukwa cha luso lodabwitsa ili, asayansi ali ndi chiyembekezo chachikulu pa izi.
Kodi maselo amenewa timawapeza kuti?
Pali njira ziwiri zazikulu zopezera maselo oyambira.
1. Kuchokera m'thupi la munthu wamkulu: M'zigawo zina za thupi lathu, mwachitsanzo, mu fupa la mafuta , muli maselo oyambira ochepa. Izi zimapangitsa kuti pakhale zinthu monga maselo atsopano a magazi. Izi zimatchedwa maselo oyambira akuluakulu.
2. Kuchokera ku Mazira: Iyi ndi njira yomwe imakambidwa kwambiri komanso yotsutsana kwambiri. Izi zikutanthauza kuti, maselo amenewa amapezeka kuchokera ku mluza, womwe ndi gawo loyamba la moyo wa munthu. Nthawi zambiri amatengedwa kuchokera ku mluza womwe umayenera kuchotsedwa kwa maanja omwe akulandira chithandizo cha in vitro fertilization (IVF) , ndi chilolezo chawo.
Kawirikawiri, pamene banja lomwe likufuna kukhala ndi ana limalandira chithandizo cha IVF, mazira angapo amapangidwa kuti awonjezere kupambana. Pambuyo poti imodzi kapena ziwiri zaikidwa m'chiberekero cha mayi, mazira otsalawo nthawi zina amawonongeka. M'mayiko ambiri, mazira omwe akanatayidwa ndi omwe aloledwa kugwiritsidwa ntchito pa kafukufukuyu.
Kodi ubwino wodabwitsa wa ukadaulo uwu ndi wotani?
Chabwino, tsopano tiyeni tiwone ubwino womwe tingapeze kuchokera ku maselo odabwitsa awa. Tangoganizani kuti maselo omwe ali m'thupi lathu afa chifukwa cha matenda. Nanga bwanji ngati tingasinthe maselo akufawo ndi maselo atsopano, athanzi ndikuwayika pamalo amenewo? Ndicho cholinga chachikulu cha kafukufuku wa maselo oyambira.
| Matenda | Yankho lomwe maselo oyambira angapereke |
|---|---|
| Matenda a Shuga (Diabetes Mellitus) | Matenda a shuga amapezeka pamene maselo a kapamba omwe amapanga insulin amawonongeka. M'malo mwake, maselo atsopano opanga insulin amatha kupangidwa mu labotale ndikulowetsedwa m'thupi. |
| Matenda a Parkinson | Matendawa amayamba chifukwa cha kufa kwa maselo muubongo omwe amapanga mankhwala otchedwa dopamine. M'malo mwake, maselo atsopano opanga dopamine amatha kupangidwa ndikulowetsedwa muubongo. |
| Kufa ziwalo | N'zotheka kuyesa kubwezeretsa ntchito yomwe yatayika mwa kukonzanso maselo amitsempha omwe awonongeka pangozi. |
| Matenda a Mtima | Maselo amenewa angagwiritsidwe ntchito kukonzanso ziwalo za minofu ya mtima zomwe zawonongeka ndi matenda a mtima. |
Koma ... pali vuto lalikulu la makhalidwe abwino ndi izi.
Kaya ukadaulo uwu ndi wabwino bwanji, pali mikangano yambiri komanso mkangano wokhudza lingaliro lopeza maselo awa kuchokera ku mazira. Pali malingaliro awiri akuluakulu pankhaniyi.
Mbali ina imati izi zitha kupulumutsa miyoyo yambirimbiri. Kumbali ina, izi zimagwiritsa ntchito mazira omwe akanawonongeka. Asayansi ndi ofufuza ambiri amakhulupirira kuti palibe cholakwika ndi kuchitira anthu zabwino. Amaona izi ngati chida chasayansi chomwe chingapulumutse miyoyo.
Koma mbali ina , makamaka magulu achipembedzo ndi omwe amasamala kwambiri za makhalidwe abwino, akufotokoza nkhani yosiyana kwambiri. Mtsutso wawo ndi wakuti mwana wosabadwa, ngakhale atakhala wamng'ono bwanji, ndiye chiyambi cha moyo wa munthu. Chifukwa chake, kuwononga moyo umenewo chifukwa cha kafukufuku n'kolakwika. Malinga ndi iwo, izi zikupanga "miyoyo ya anthu yotayidwa."
Mwachidule, funso lawo ndi lakuti, 'Kodi n'koyenera kuwononga moyo wa munthu wina (ngakhale mwana wosabadwa) kuti mupulumutse moyo wa munthu mmodzi?'
Mkhalidwe ndi tsogolo la dziko lapansi
Chifukwa cha mkanganowu, mayiko ena akhazikitsa malamulo okhwima pa kafukufukuyu. Mayiko ena, monga England, alola kafukufukuyu kuti apitirire ndi zoletsa. Izi nthawi zambiri zimapangitsa ofufuza kukayikira. Chifukwa kafukufuku wochitidwa pamtengo wapatali amatha kuyima mwadzidzidzi chifukwa cha chisankho cha ndale.
Koma odwala ndi mabanja awo omwe akudwala matenda monga matenda a shuga ndi Parkinson ali ndi chiyembekezo chachikulu kuti kafukufukuyu apitirire mwachangu. Ichi ndichifukwa chake nthawi zonse amakweza mawu awo kuti athandizire kafukufukuyu.
Izi ndi kufotokozera chabe njira inayake. Tikukukumbutsaninso kuti nthawi zonse muzilankhula ndi dokotala wa banja lanu za matenda aliwonse omwe mungakhale nawo.
Uthenga Wopita Nawo Kunyumba
- Maselo oyambira ndi mtundu wapadera wa selo loyambira lomwe lingakhale selo lililonse m'thupi lathu.
- Pali chiyembekezo chachikulu kuti izi zidzatha kuchiza matenda monga matenda a shuga ndi ziwalo.
- Popeza izi zimapezeka kuchokera ku mazira, pali mkangano waukulu pakati pa omwe amaona kuti 'kuwononga moyo wa munthu' ndi omwe amaona kuti 'kuchita bwino ndi mazira omwe atayika'.
- Nkhaniyi ndi yovuta kwambiri. Kupeza mgwirizano pakati pa kupita patsogolo kwa sayansi ndi makhalidwe abwino a anthu ndiye vuto lalikulu kwambiri la mtsogolo.
