Pamwe wakambosangana neshoko rekuti ' Stem Cells ' mumafirimu, munhau, kana paindaneti. Vamwe vanoti vanogona kurapa chero chirwere, nepo vamwe vachiti vanogona kuva nengozi. Saka, chii chinonzi stem cells? Ari kuchinja remangwana remishonga zvechokwadi here? Ngatizvitsanangure zviri nyore.
Nemashoko akareruka, chii chinonzi stem cells?
Funga nezvebundu revhu. Unogona kuriumba kuita chidhori, hari, kana chivezwa. Masero emuviri anoshanda nenzira yakafanana; ndiwo masero 'akakosha' kana kuti 'anonyanya kukosha' emuviri. Masero aya ane mabasa maviri anoshamisa:
1. Kuzvivandudza: Sero rekutanga rinogona kupatsanurana nekugadzira mamwe emhando yaro.
2. Kusiyanisa: Ichi ndicho chinhu chavo chinoshamisa. Masero emuviri anogona kushanduka kuita masero akakosha anodiwa nemuviri. Semuenzaniso, anogona kuva masero eropa , masero europi ( neurons ), masero emhasuru dzemwoyo, masero eganda , kana masero emapfupa .
Hapana rimwe sero mumuviri wako rine hunyanzvi hwakadai, ndosaka vanachiremba nemasayendisiti vachifara zvikuru nehunyanzvi hwavo.
Sei Masero Emuviri Achikosha Kwazvo?
Masayendisiti anotenda kuti masero emuviri ndiwo anotungamira kuchinjo mune zvehutano hweramangwana. Anokosha nekuda kwezvikonzero zvitatu zvikuru:
| Kukosha | Tsananguro Iri Nyore |
|---|---|
| Kurapa kwakavakirwa pamasero | Fungidzira mumwe munhu aine moyo wakakuvara. Dai taigona kushandisa masero ekutanga kukura masero emhasuru dzemwoyo ane hutano uye toaisa munzvimbo yakakuvara, izvozvo zvaizochinja. Izvi zvinozivikanwa seRegenerative Medicine — sainzi yekugadzirisa kana kutsiva nyama nenhengo dzakakuvara. |
| Kunzwisisa Kufambira Mberi Kwezvirwere | Nekuona kuti stem cell inoshanduka sei kuita cancer kana kuti cell ine chirwere murabhoritari, vaongorori vanogona kunzwisisa zviri nani kuti zvirwere zvinotanga sei uye zvinokura sei. Ruzivo urwu rwakakosha pakutsvaga mishonga mitsva. |
| Kuedza Mishonga Mitsva | Tisati taedza mishonga mitsva pavanhu, tinofanira kuva nechokwadi chekuti yakachengeteka uye inoshanda. Masayendisiti anogona kugadzira masero anoenderana nechirwere (semuenzaniso, masero echiropa) murabhoritari achishandisa masero ekutanga kuyedza kuti mushonga unoita sei, zvichipa mufananidzo wakajeka tisati taedza mishonga. |
Ndeapi Marudzi Makuru eMaseru Ekutanga?
Kazhinji, tinoisa masero ekutanga mumapoka maviri makuru:
1. Masero Ekutanga eEmbryonic
Aya ndiwo masero 'akanaka' ane simba guru. Sezvinoreva zita racho, anobva muma embryo, kunyanya ayo asara kubva mukurapwa kwekubereka (sengeIVF ) uye yakashandiswa pakutsvagisa nemvumo yakazara yevabereki.
Aya anozivikanwa semasero e'pluripotent', zvichireva kuti anogona kushanduka kuita chero rudzi rwesero mumuviri. Nekuda kweizvi, ane tariro huru yekugadzirisa nyama, kunyangwe kushandiswa kwawo kuchiramba kuri nyaya yenhaurirano pasi rose.
2. Masero Evanhu Vakuru
Pasinei nezita racho, masero aya anowanikwa mumunhu wese—vacheche, vana, nevakuru. Haana simba rakakwana pane masero emucheche uye anowanzo kuwanikwa muzvikamu zvidiki munyama dzakadai semupfupa, ganda, uropi, nechiropa.
Masero eganda evakuru anowanzo gadzira masero chaiwo emuviri waanogara. Semuenzaniso, masero eganda anowanzo gadzira masero matsva eganda, kwete masero emwoyo.
Kubudirira kweSainzi: Masero eIPS
Masayendisiti akawana nzira yekutora sero revanhu vakuru, sesero reganda, vorigadzirisa murabhoritari kuti riite sesero remwana ari mudumbu. Aya anonzi masero eInduced Pluripotent Stem (masero eiPS) . Kubudirira uku kwakavhura masuo matsva ekutsvagisa uku vachipfuura zvinonetsa zvetsika zvine chekuita nemasero ari mudumbu.
Ndeapi Marapirwo Aripo Iye Zvino?
Zvakakosha kusiyanisa pakati pemishonga yakasimbiswa neongororo yekuedza .
Kurapa Kwakatenderwa uye Kwakashandiswa Pari Zvino
Kurapa kunonyanya kuitwa uye kunobudirira nhasi ndiko kuisirwa masero eropa , kunowanzozivikanwa se 'kuisirwa masero emapfupa'.
Uku ndiko kutarisirwa kwakajairika kwe:
- Kenza dzeropa (semuenzaniso, Leukemia, Lymphoma)
- Zvimwe zvirwere zveropa (semuenzaniso, Sickle cell anemia)
- Kudzorera mapfupa akaparadzwa ne chemotherapy.
Masero aya anowanzo torwa kubva kune vanopa vane hutano hwakanaka kana kubva muropa remudumbu rinounganidzwa pakuzvarwa.
Tariro dzeramangwana uye Tsvagiridzo yekuedza
Masayendisiti ari kushanda kuti ashandise stem cell therapy kune mamwe matambudziko akawanda. Ndapota yeukai kuti izvi zvichiri muchikamu chekuedza:
- Chirwere cheParkinson
- Chirwere cheAlzheimer
- Chirwere cheshuga
- Chirwere chemwoyo
- Kukuvara kwemusana
- Arthritis
Zvakakosha: Kana kiriniki ichiti inopa 'mishonga yemasero emuviri yakavimbiswa' yezvirwere izvi, chenjera zvikuru. Aya haasi marapirwo akajairwa asati atenderwa. Gara uchikurukura sarudzo dzakadaro nachiremba wako wekutanga.
Kurapa Uku Kwakachengeteka Here?
Kufanana nechero tekinoroji itsva yekurapa, kurapwa nemasero ekutanga kune njodzi dziri kushanda nevaongorori kuderedza:
- Njodzi yeKuumbwa kweBundu: Nekuti masero emuviri anopatsanuka nekukurumidza, pane njodzi yekuti anogona kukura zvisingadzoreki, ogadzira bundu.
- Kukuvadzwa Kwemajini: Masero anoshandiswa murabhoritari anogona kuchinja majini.
- Kurambwa Kwemasoja Emuviri: Masoja emuviri wako anogona kuona masero evanopa se'vapambi vekune dzimwe nyika' obva avarwisa.
- Njodzi Dzekuvhiyiwa: Maitiro anodiwa pakukohwa kana kuisa masero (akadai sekubaiwa majekiseni muuropi kana mumoyo) ane njodzi dzekuvhiyiwa.
Kutsvaga kurapwa kubva ku "stem cell clinics" dzisina kusimbiswa kana dzisina kurongeka kunogona kuva nengozi huru. Nguva dzose tanga waisa pfungwa pakutarisirwa kwakachengeteka uye kwakavakirwa pauchapupu.
Mharidzo Yekuenda Nayo Kumba
- Masero emuviri (stem cells) imasero makuru akasiyana anokwanisa kuva chero rudzi rwesero mumuviri uye ane mukana mukuru wekurapa.
- Parizvino, kurapwa kwemasero eropa kunobudirira kunonyanya kushandiswa pakurapa kenza yeropa uye mamwe matambudziko eropa.
- Kurapa chirwere cheshuga, chirwere cheParkinson, uye chirwere chemwoyo kuchiri kutsvagurudzwa uye hakusati kwatenderwa kushandiswa nevanhu vose.
- Usati watenda ruzivo rwaunowana paindaneti maererano nekurapa masero ekutanga, ndapota simbisa nachiremba wako kana nyanzvi yezvekurapa ine hunyanzvi.
- Chenjererai 'makiriniki emasero emuviri' asina kusimbiswa anovimbisa mhedzisiro inoshamisa. Musaisa hutano hwenyu panjodzi.
