Pamwe wakambonzwa izwi rekuti "Stem Cell". Pane zvakawanda zvinotaurwa nezvazvo senzira yekugadzirisa zvirwere zvakawanda zvichiri kuoma kurapa, zvakaita sechirwere cheshuga, chirwere cheParkinson, uye kuoma mitezo. Saka ngatitarisei kuti masero aya ndeapi chaizvo, mabhenefiti api atinogona kupa, uye nei paine gakava guru pamusoro pawo pasi rose.
Ndezvipi masero aya emuviri?
Zvichitaurwa zviri nyore, sero resimbi rakafanana nebundu revhu risina chimiro. Tinogona kutora bundu iri revhu toriumba kuita chero chatinoda, sehari kana chifananidzo. Ndizvo zvinoita kuti masero aya esimbi ave chero rudzi rwesero rakasiyana mumuviri wedu. Aya ndiwo "masero makuru" mumuviri wedu.
Kureva kuti, rudzi urwu rwemasero ekutanga runogona, zvichienderana nekudiwa, kushanduka kuita sero reganda , sero retsandanyama dzemwoyo , sero retsinga dzeuropi , kana sero rinogadzira insulin mupancreas . Imhaka yekugona uku kunoshamisa ndiko kunoita kuti masayendisiti ave netariro huru yeizvi.
Masero aya tinoawana kupi?
Kune nzira mbiri huru dzekuwana masero emuviri.
1. Kubva mumuviri wemunhu mukuru: Mune dzimwe nhengo dzemuviri wedu, semuenzaniso, mumongo wemapfupa , mune huwandu hushoma hwemasero aya. Aya ndiwo anokonzera zvinhu zvakaita semasero matsva eropa. Aya anonzi masero emuviri wemunhu mukuru.
2. Kubva kuMazai: Iyi ndiyo nzira inonyanya kutaurwa nezvayo uye inokakavadzana. Kureva kuti, masero aya anowanikwa kubva kumwana ari mudumbu, inova ndiyo nhanho yekutanga yehupenyu hwemunhu. Aya anowanzotorwa kubva kumwana ari mudumbu anofanira kubviswa kubva kune vakaroorana vari kurapwa neIVF , kana vachinge vabvumirana.
Kazhinji, kana vaviri vari kuda kuva nevana vachipinda muchirongwa cheIVF, mazai akawanda anogadzirwa kuti awedzere kubudirira kwavo. Mushure mekunge rimwe kana maviri aiswa muchibereko chaamai, mazai asara anoparadzwa dzimwe nguva. Munyika dzakawanda, mazai angadai akaraswa ndiwo akabvumirwa kushandiswa muongororo iyi.
Ndezvipi zvakanakira zvinoshamisa zve tekinoroji iyi?
Zvakanaka, ngationei kuti tingawana mabhenefiti api kubva kumasero aya anoshamisa. Fungidzira kuti masero ari muchikamu chemuviri wedu akafa nekuda kwechirwere. Ko kana tikakwanisa kutsiva masero akafa nemasero matsva, ane hutano toaisa panzvimbo iyoyo? Ndiyo chinangwa chikuru chekutsvagisa masero ekutanga.
| Dambudziko rehutano | Mhinduro inogona kupihwa nemasero ekutanga |
|---|---|
| Chirwere cheshuga (chirwere cheshuga) | Chirwere cheshuga chinoitika kana masero ari mupancreas anogadzira insulin akaparadzwa. Asi, masero matsva anogadzira insulin anogona kugadzirwa murabhoritari uye kuiswa mumuviri. |
| Chirwere cheParkinson | Chirwere ichi chinokonzerwa nekufa kwemasero ari muuropi anogadzira kemikari inonzi dopamine. Pane kudaro, masero matsva anogadzira dopamine anogona kugadzirwa oiswa muuropi. |
| Kuoma mitezo | Zvinokwanisika kuedza kudzoreredza mashandiro akarasika nekugadzirazve masero etsinga akakuvara mutsaona. |
| Chirwere chemwoyo | Masero aya anogona kushandiswa kugadzirazve zvikamu zvetsandanyama yemoyo zvakakuvadzwa nechirwere chemwoyo. |
Asi ... pane nyaya huru yetsika neizvi.
Kunyangwe tekinoroji iyi yakanaka sei, pane gakava guru uye gakava pamusoro pepfungwa yekuwana masero aya kubva kumbeu. Pane pfungwa mbiri huru pane izvi.
Rimwe divi rinoti izvi zvinogona kuponesa zviuru zvehupenyu. Kune rumwe rutivi, izvi zvinoshandisa mazai emucheche angadai akaparadzwa. Saka masayendisiti nevaongorori vazhinji vanotenda kuti hapana chakaipa nekuitira vanhu zvakanaka. Vanoona izvi sechishandiso chesainzi chinogona kuponesa hupenyu.
Asi rimwe divi , kunyanya mapoka ezvitendero neavo vane hanya zvikuru netsika, vanotaura nyaya yakasiyana zvachose. Nharo yavo ndeyekuti mwana asati aberekwa, zvisinei nekuti mudiki sei, ndiwo mavambo ehupenyu hwemunhu. Saka, kuparadza hupenyu ihwohwo nekuda kwekutsvaga kwakaipa. Sekureva kwavo, izvi zviri kugadzira "hupenyu hwevanhu hwakaraswa."
Muchidimbu, mubvunzo wavo ndewokuti, 'Zvakanaka here kuparadza mumwe munhu (kunyangwe mwana ari mudumbu) kuti uponese mumwe munhu?'
Mamiriro ezvinhu uye remangwana renyika
Nekuda kwegakava iri, dzimwe nyika dzakaisa mitemo yakaoma pakutsvagurudza uku. Dzimwe nyika, dzakadai seEngland, dzakabvumira kutsvagurudza uku kuenderera mberi nemirau. Izvi zvinowanzosiya vaongorori vachizeza. Nekuti kutsvagurudza kunoitwa nemari yakawanda kunogona kumira kamwe kamwe nekuda kwechisarudzo chezvematongerwo enyika.
Asi varwere nemhuri dzavo vanorwara nezvirwere zvakaita sechirwere cheshuga neParkinson's vane tariro huru yekuti tsvakiridzo iyi ifambire mberi nekukurumidza. Ndosaka vachigara vachisimudza manzwi avo kutsigira tsvakiridzo iyi.
Iyi ingori tsananguro yenzira yekushandisa. Tinokuyeuchidzawo kuti ugare uchitaura nachiremba wemhuri yako nezve chero chirwere chaungave nacho.
Mharidzo Yekuenda Nayo Kumba
- Masero emuviri imhando yakakosha yesero rekutanga rinogona kuva chero sero mumuviri wedu.
- Pane tariro huru yekuti izvi zvichakwanisa kurapa zvirwere zvakaita sechirwere cheshuga nekuoma mitezo.
- Nekuti izvi zvinotorwa kubva mumbeu dzinobereka mwana, pane gakava guru retsika pakati pevaya vanofunga kuti 'zvinoparadza hupenyu hwevanhu' nevaya vanofunga kuti 'zvinoita zvakanaka nembeu inoraswa'.
- Iyi inyaya yakaoma zvikuru. Kuwana chiyero pakati pekufambira mberi kwesainzi netsika dzevanhu ndiro dambudziko guru remangwana.
