Chithandizo cha Maselo Oyambira: Chozizwitsa Chotsatira mu Zamankhwala?

Muyenera kuti mukumva mawu oti ' Stem Cell ' nthawi zonse tsopano, sichoncho? Ena amati iyi ndi njira yatsopano yochiritsira matenda ambiri. Nthawi zina imakambidwa m'manyuzipepala ndi pa TV. Ndiye kodi chithandizo cha maselo oyambira awa ndi chiyani kwenikweni? Kodi izi zikugwiritsidwa ntchito pa anthu tsopano? Tiyeni tikambirane za izi mosavuta komanso momveka bwino.

Mwachidule, kodi selo loyambira ndi chiyani?

Ganizirani maselo oyambira ngati maselo 'apamwamba' m'matupi athu. Monga bwana amene amayang'anira ntchitoyo asanapatsidwe ntchitoyo. Maselo amenewa ali ndi mphamvu zodabwitsa zokhala mtundu uliwonse wa selo m'thupi (monga maselo a minofu ya mtima, maselo a mitsempha ya ubongo, maselo a khungu , maselo a chiwindi). Chifukwa cha luso limeneli, asayansi amakhulupirira kuti angagwiritsidwe ntchito kukonza minofu yowonongeka kapena kupanga maselo atsopano kuti alowe m'malo mwa maselo omwe awonongedwa ndi matenda.

Pakadali pano pali mayeso ambiri azachipatala omwe akuchitika padziko lonse lapansi pankhaniyi. Koma chofunika kwambiri kukumbukira ndichakuti kafukufuku wambiri akadali koyambirira . Izi zikutanthauza kuti, tisanawone momwe chithandizochi chilili chothandiza, choyamba tiyenera kudziwa ngati chili chotetezeka kupereka kwa anthu . Chifukwa mu mankhwala, chitetezo nthawi zonse chimakhala choyamba.

Kodi madera akuluakulu ofufuza maselo oyambira ndi ati?

Pakadali pano, pali chidwi chachikulu pa kafukufuku wa maselo oyambira matenda ndi matenda akuluakulu 11. Tiyeni tiwone chilichonse mwatsatanetsatane.

1. Matenda a Mtima

Zolinga ziwiri zazikulu ndi kukonza minofu ya mtima yomwe yawonongeka ndi matenda a mtima komanso kukulitsa mitsempha yatsopano yamagazi . Mu kafukufuku wina, mafupa a wodwalayoMaselo oyambira omwe atengedwa kuchokera ku mafupa akalowetsedwa mumtima, akuwonetsa zizindikiro zakuchira mabala omwe amabwera chifukwa cha matenda a mtima . Kuphatikiza apo, anthu ena awona kusintha pang'ono pakugwira ntchito kwa mtima. Koma ndikofunikira kukumbukira kuti uku ndi kafukufuku woyambirira .

2. Matenda a Maso

Kafukufuku wa ku UK wasonyeza kuti kusamutsa mtundu wapadera wa selo loyambira lomwe latengedwa kuchokera kunja kwa cornea (limbal stem cells) kungabwezeretse masomphenya kwa anthu omwe akhungulidwa ndi matenda a retina. Mofananamo, kafukufuku wogwiritsa ntchito maselo oyambira omwe atengedwa kuchokera ku mazira a anthu (embryonic stem cells) pa matenda monga macular degeneration wasonyezanso kuti wapambana poyamba.

3. Matenda a Shuga (Mtundu woyamba wa Matenda a Shuga)

Mu matenda a shuga amtundu woyamba, chitetezo cha mthupi chimawononga maselo a beta omwe amapanga insulin mu kapamba. Chifukwa chake ngati maselo a beta awa atha kubwezeretsedwanso pogwiritsa ntchito maselo oyambira, zitha kumasula anthu kuti asalandire jakisoni wa insulin tsiku lililonse. Mu kafukufuku wofanana, achinyamata 15 odwala matenda a shuga adatha kukhala opanda insulin kwa zaka pafupifupi 1.5 pogwiritsa ntchito maselo oyambira a odwalawo. Koma popeza uwu ndi kafukufuku waung'ono kwambiri , palibe mfundo zazikulu zomwe zingapezeke.

4. Stroke

Kufa ziwalo ndi imfa ya maselo a muubongo chifukwa cha kusowa kwa magazi kupita ku ubongo . Chifukwa chake, akufufuzidwa ngati maselo oyambira angagwiritsidwe ntchito kukonza minofu yaubongo yowonongekayi. Mu kafukufuku wochitidwa ku Scotland, maselo oyambira a ubongo wa fetal ('maselo oyambira a ubongo wa fetal') adalowetsedwa muubongo wa odwala olumala. Cholinga chachikulu apa chinali chitetezo . Pachifukwa ichi, chithandizochi chawonetsedwa kuti ndi chotetezeka. Komabe, sizingatheke kunena kuti zizindikiro zake zachepa bwanji.

5. Kuvulala kwa Msana

Pali chidwi chachikulu chothandiza anthu omwe ali ndi vuto la msana lomwe lawapangitsa kuti asakhale ndi maselo oyambira. Ngakhale kuti kafukufuku wokhudza kubwezeretsa maselo oyambira omwe atengedwa m'magazi a odwalawo wasonyeza kupita patsogolo pang'ono, sipanakhalepo chipambano chokhazikika komanso cha nthawi yayitali .

6. Matenda a Parkinson ndi Alzheimer's

Pali maphunziro ang'onoang'ono kwambiri omwe akuchitika okhudza matenda a Parkinson, koma ndi msanga kwambiri kuti tikambirane za zotsatira zake. Ponena za matenda a Alzheimer, mayeso a anthu sanayambebe.

7. Matenda a Multiple Sclerosis (MS)

Imeneyinso ndi matenda omwe amayamba chifukwa cha kulephera kwa chitetezo chamthupi. Chomwe chikuchitika pano ndikuletsa chitetezo chamthupi cha wodwalayo ndi mankhwala, kenako ndikubwezeretsanso maselo oyambira omwe atengedwa kuchokera ku mafupa a wodwalayo kupita m'thupi, ndikupanga chitetezo chamthupi 'chatsopano' chathanzi. Ngakhale izi zawonetsa kupambana pang'ono, kuletsa kwathunthu chitetezo chamthupi ndi koopsa kwambiri , kotero kuyenera kuganiziridwa kwambiri musanapereke chithandizochi.

8. Khansa

Mbali imodzi yomwe chithandizo cha maselo oyambira chikugwiritsidwa ntchito kale bwino ngati chithandizo chodziwika bwino chamankhwala ndi khansa ya m'magazi monga khansa ya m'magazi. 'Kusamutsira mafupa' komwe tonse tamvapo kwenikweni ndi kusamutsira maselo oyambira.

Kuphatikiza apo, maselo oyambira akugwiritsidwa ntchito pochiza khansa ya muubongo yotchedwa `Glioblastoma`. Pano, maselo oyambira osinthidwa majini amagwiritsidwa ntchito kupita ku maselo a khansa ndikuyambitsa mankhwala oletsa khansa. Izi zikadali mu gawo lofufuza.

9. Kukonza Cartilage

Maselo oyambira akuyesedwa kuti awone ngati angagwiritsidwe ntchito kukonza chipolopolo chosweka m'malo olumikizirana mafupa monga bondo ndi akakolo. Maselo oyambira omwe atengedwa kuchokera ku mafupa a wodwalayo amasakanizidwa ndi gel kenako n’kuikidwa m’malo owonongekawo. Koma zotsatira zake zasakanizidwa. Nthawi zina chipolopolo chatsopano chomwe chimapangidwa sichimakhala cholimba monga momwe chiyenera kukhalira, zomwe zakhala vuto.
