"Stem Cell" tih thumal hi i hre tawh ngei ang. Hei hi natna tam tak tihdam harsa tak tak, zunthlum, Parkinson natna, leh paralysis te tihdamna tur a nih thu sawi a tam hle. Chuvangin heng stem cells te hi eng nge an nih tak tak a, eng hlawkna nge min pek theih tih te, engvangin nge khawvelah hian an chungchangah hian inhnialna lian tak a awm tih hi han thlir ila.
Heng stem cell te hi engte nge ni?
A awlsam zawngin sawi ila, stem cell chu leilung hnim hring, pianzia nei lo ang mai a ni. He leilung hnah hi kan la thei a, kan duh duh angin kan siam thei a, vase emaw, milem emaw ang chi hi a ni. Chutiang chuan heng stem cell te hi kan taksaah hian specialized cell chi hrang hrang an lo ni thei a ni. Hengte hi kan taksaa "master cells" te an ni.
Chu chu, he stem cell chi khat hi a mamawh dan azirin vun cell , thinlung ruh cell , thluak nerve cell , a nih loh leh pancreas-a insulin siamtu cell- ah a chang thei tihna a ni. Hetiang theihna mak tak avang hian scientist-te chuan he thil hi beiseina sang tak an nei a ni.
Heng cell te hi khawi atanga kan hmuh nge?
Stem cells hmuh dan tlangpui pahnih a awm a.
1. Puitling taksa a\angin: Kan taksa hmun \henkhatah, entirnan, ruhroah , heng stem cells te hi a tlem hle. Chûngte chuan thisen cell thar ang chi thil a siam chhuak a ni. Chungte chu puitling stem cell an ti a.
2. From Embryos: Hei hi sawi hlawh ber leh sawisel hlawh ber a ni. Chu chu heng cell te hi embryo atanga lak chhuah a ni a, chu chu mihring nun hmasa ber a ni. Hengte hi in vitro fertilization (IVF) hmanga enkawl mek nupa atanga lak chhuah tur embryo atanga lak a ni tlangpui a, an remtihna nen.
Vawi tam tak chu fa neih tum nupa tuak khatin IVF hmanga enkawlna an paltlang hian hlawhtlinna rate tihpun nan embryo tam tak siam a ni. An zinga pakhat emaw pahnih emaw chu nu nausen pum chhungah an dah hnuah embryo la awmte chu a chang chuan a chhe vek a ni. Ram tam takah chuan engti kawng pawhin paih chhuah mai tur embryo te hi he zirchianna atana hman phalsak an ni.
He technology hian hlawkna mak tak tak a neihte chu engte nge ni?
Awle, tunah chuan heng cell mak tak tak atang hian eng hlawkna nge kan hmuh theih ang tih i lo en ang u. Kan taksa peng pakhata cell awmte chu natna avanga thi tawh angin han ngaihtuah teh. Chu cell thite chu cell thar, hrisel tak tak hmanga thlak a, chu hmunah chuan kan dah lut thei a nih chuan engtin nge ni ang? Chu chu stem cell zirchianna tum ber a ni.
| Damdawi lam dinhmun | Stem cell-in a pek theih solution chu |
|---|---|
| Zunthlum (Diabetes Mellitus) natna a ni. | Diabetes hi pancreas-a insulin siamtu cell-te a chhiat chuan a lo awm thin. Chu ai chuan laboratory-ah insulin siamtu cell thar siamin taksaah inject theih a ni. |
| Parkinson natna a ni | He natna hi thluaka cell te thihna avanga lo awm a ni a, chu chuan chemical dopamine an tih chu a siam chhuak thin. Chu ai chuan dopamine siamtu cell thar siamin thluaka dah luh theih a ni. |
| Paralysis a awm | Accident-a nerve cell chhia te siam thar lehin hnathawh hloh tawh chu siam\hat tum theih a ni. |
| Lung Natna | Heng cell te hi heart muscle hmun thenkhat, heart attack avanga chhiat tawhte siam thar lehna atan hman theih a ni. |
Mahse... he thil hi moral issue lian tak a awm.
He technology hi eng ang pawhin tha mahse, embryo atanga heng cell te hi lak chhuah tumna chungchangah hian sawiselna leh inhnialna nasa tak a awm a ni. Hemi chungchangah hian ngaihdan lian tak pahnih a awm a.
A lam pakhat chuan hei hian mi sang tam tak nunna a chhanhim thei niin an sawi. Kawng lehlamah chuan hei hian embryo a hmang a, chutiang ni lo se chuan tihchhiat theih a ni. Chuvangin scientist leh zirchiangtu tam tak chuan mi tana thil tha tih hi thil dik lo a awm lo niin an ngai. Hei hi scientific hmanrua, nunna chhanhim thei angah an ngai a ni.
Mahse a lehlamah , a bik takin sakhaw pawl leh nungchang lama ngaihtuahna nasa tak neitute chuan thawnthu danglam tak a sawi a ni. An thusawi chu embryo chu eng ang pawhin te mah se, mihring nun bul tanna a ni tih hi a ni. Chuvang chuan, chu nun chu zirchianna avanga tihchhiat chu thil dik lo a ni. An sawi dan chuan hei hian "mihring nunna paih" a siam a ni.
A awlsam zawngin, an zawhna chu, ‘Mihring pakhat nunna chhanhim nan mihring nunna dang (nausen pawh) tihchhiat hi nungchang lamah a dik em?’ tih hi a ni.
Khawvel dinhmun leh hmalam hun
He inhnialna avang hian ram thenkhat chuan he zirchianna chungchangah hian dan khauh tak tak an siam a ni. Ram dang, England ang pawhin he zirchianna hi khapna nen chhunzawm zel an phalsak a ni. Hei hian zirchiangtute chu a ti inhnial fo thin. A chhan chu sum tam tak senga zirchianna an neih chu politics thutlukna avang hian a tawp nghal mai thei a ni.
Mahse damlo leh an chhungte, zunthlum leh Parkinson’s ang chi natna vei te chuan he zirchianna hi hmalam pan thuai turin beiseina sang tak an nei a ni. Chuvangin he zirchianna hi thlawp turin an aw an ti sang reng a ni.
Hei hi technique pakhat sawifiahna mai a ni. Tin, damdawi lam harsatna i neih apiang chu i chhungkaw doctor nen inbiakna nei reng turin kan hriattir bawk.
Take-Home Thuchah a ni
- Stem cell hi kan taksa chhunga cell eng pawh lo ni thei, basic cell chi khat bik a ni.
- Hengte hian zunthlum leh paralysis ang chi natnate a tidam thei ngei ang tih beiseina lian tak a awm.
- Hengte hi embryo atanga hmuh a nih avangin ‘mihring nunna tichhe thei’ tia ngai leh ‘embryo paih chhuah hmanga thil tha tih’ tia ngaite inkarah hian ethical debate lian tak a awm a ni.
- Hei hi thupui buaithlak tak a ni. Science lama hmasawnna leh mihring nungchang inthlauhna zawng chu nakin hun atana harsatna lian ber a ni.
