' Stem Cells ' tih thumal hi i lo hre tawh em? Doctor hnen atangin emaw, TV show-ah emaw, chanchinbu thuziak atang emaw pawhin i hre tawh mai thei. Hei hi thupui buaithlak tak angin lang mah se, a takah chuan heng stem cells te hi kan taksaa thil mak ber pakhat an ni. Vawiin hian he thu hi a awlsam em em, i hriatthiam theih dan tur angin kan sawi dawn a ni.
A awlsam zawngin, heng stem cells te hi engte nge ni?
Lego chi khat chi khat bunch khat i nei ang tih han ngaihtuah teh. Chu Lego piece te chu in, car, lawng, i duh duh siam nan i hmang thei ang. Stem cells te chu chutiang chu a ni.
Stem cells hi kan taksaa "basic" emaw "master" cell chi khat, specialized cell chi dang eng pawh ni thei tur a ni.
Entirnan, stem cell chu vun cell, thluak cell ( nerve cell), thinlung thau cell, ruh cell, emaw thisen cell-ah a lo thang lian thei a ni. Tin, heng cell te hian stem cell tam zawk an siam thei a, chu chu an inthen darh thei a, anmahni ang cell an siam leh thei bawk. He thiamna mak tak mai hi damdawi lama pawimawhna nasa tak an neih chhan a ni.
Chuti a nih chuan, engvangin nge heng stem cells te hi an pawimawh em em?
Heng cell te hi an theihna avang hian nakin lawka medical research-ah an pawimawh hle a ni. Chhan lian pathum vangin an pawimawh a ni.
1. Cell-based therapies: Mi pakhatin heart attack a nei a, a thinlung hmun thenkhat chu a thi a, a chak lo hle tih han ngaihtuah teh. Scientist-te chuan nakin lawkah chuan stem cell hmangin thinlung cell thar, hrisel tak tak siamin, a chhiatna hmunah dahin, thinlung chu a siam ṭha leh thei dawn niin an ngai Hei hi regenerative medicine kan tih chu a ni . Hetiang method hi thisen natna leh cancer thenkhat tan pawh hlawhtling takin hman a ni tawh a .
2. Natna lo awm dan hriatthiam nan:Scientist-te chuan stem cell, entirnan, lab-ah nerve cell-a a lo thanglian chu an en thei a ni. Hei hian Parkinson natna emaw Alzheimer natna emaw ang chi natnaah nerve cell-a thil thleng dik tak chu a zir chiang thei a ni. Natna lo awm dan dik tak hriatthiamna chuan enkawlna zawng turin a pui thei a ni.
3. Damdawi thar enchhin tur: Damdawi thar mi hnena pek a, test a nih hma chuan a him leh tangkai em tih hriat a ngai. Chuvangin, natna sawi tur nena inzawm specialized cells (entir nan, zunthlum tan pancreatic cells) chu laboratory-ah stem cells atangin siam theih a ni a, chu damdawi thar chu chu cells-ah chuan hman theih a ni a, a nghawng chu test theih a ni bawk.
Stem cell chi hrang hrangte chu engte nge ni?
Stem cell hi chi hnih a awm a. Hengte hi a hranin han thlir ila.
| Cell chi hrang hrang | Hrilhfiahna awlsam tak |
|---|---|
| Embryonic Stem Cells te chu a awm a | Hengte hi in vitro fertilization (IVF) hnua early-stage embryo donated, hman loh atanga lak chhuah a ni. Heng cell te hian taksa chhunga cell chi hrang hranga awm theihna mak tak an nei a. Hei vang hian ‘pluripotent’ an ti bawk. Natnain a tihchhiat tissue leh taksa peng hrang hrang siamthatna kawngah theihna nasa tak an nei a ni. |
| Puitling Stem Cells te | An hming ni mah se, heng cell te hi nausen, naupang leh puitling taksaah an awm a. Embryonic cell angin an versatile lo. Entirnan, vunah puitling stem cell chuan vun cell tam zawk a siam thei chauh a ni. Mahse an pawimawh hle bawk. Umbilic cord thisena stem cells te pawh hi he category ah hian an tel ve bawk. |
| Induced Pluripotent Stem Cells (iPSCs) te chu a chhuak thei lo a ni. | Hei hi science lama hmasawnna thar ber a ni. Tunah chuan scientist-te chuan puitling cell pangngai, i vun cell ang chi chu an la thei tawh a, lab-ah genetic change tlemte an siam thei tawh a, ‘potentially viable’ embryonic stem cell-ah an chantir leh thei tawh dawn a ni. Hei hi hmasawnna lian tak a ni a, a chhan chu embryo hmanna nena inzawm ethical issues te a pumpelh vang a ni. |
Tunah hian heng stem cells hmang hian eng treatment nge tih mek?
Mi tam tak chuan stem cell hian natna zawng zawng a tidam thei niin an ngai a, mahse a tak takah chuan a danglam thung.
Khawvela stem cell therapy pawm tam ber leh hlawhtling ber chu bone marrow transplant a ni . Hei hian thisen siamtu stem cells transplant a huam a ni. Chungte chu bone marrow emaw umbilical cord blood atanga lak theih a ni.
He enkawlna hi a bik takin:
- Thisen cancer tan: Entirnan, leukemia leh lymphoma ang chi natna tan .
- Thisen kaihhnawih natna dangte: Sickle cell anemia ang chi natna .
- Cancer enkawlna avanga ruhro chhia siam thar lehna tur: He enkawlna hi chemotherapy emaw radiation emaw avanga ruhro tihchhiat siamthatna atan hman a ni.
A pawimawh ber chu natna dang (e.g. arthritis, diabetes, Parkinson’s) tana stem cell enkawlna tam zawk hi research stage- ah a la awm a ni . Chuvangin khawi emaw laiah hetiang enkawlna chungchang hi i hriat chuan ngaihtuah nawn leh a pawimawh hle a, thutlukna i siam hmain i doctor nen chiang takin inbiakna neih a pawimawh hle .
Heng enkawlnate hian hlauhawmna a nei em?
Ni e, damdawi zawng zawng ang bawkin hlauhawmna engemaw zat a awm.
- Heng cell te hi thunun theih lohvin an lo thang lian a nih chuan cancer tumor siam theihna a awm a ni.
- Laboratory-a cell tihpunah hian genetic damage a awm thei a ni.
- A châng chuan taksa hian heng cell dah tharte hi "ram dang" tiin a hre thei a, a hnawl (attack) thei bawk.
- Taksa chhunga cell khawlkhawm emaw, inject emaw dan (e.g., surgery) hmang hian hlauhawmna engemaw zat a awm bawk.
Stem cell zirchiannaah harsatna a awm
Puitling stem cell chungchanga zirchianna hi kum sawm tam tak chhung kalpui tawh ni mah se, embryonic stem cell chungchanga zirchianna hi kum 1998 atang khan tan chauh a ni a, chuvangin an chungchang hi hmuhchhuah tur tam tak a la awm a ni.
Harsatna lian ber pakhat chu ethical issues a ni . Embryo atanga cell hmuh chungchangah ngaihdan hrang hrang a awm a, mi thenkhat chuan he zirchianna hi an pawm lo.
Harsatna dang chu lab-a puitling stem cells tihpun harsatna leh genetic defects an neih theihna sang lutuk hi a ni. Heng zawng zawng karah hian scientist-te chuan heng cell mak tak takte thuruk hi an la chhui chhuak zel a ni.
Take-Home Thuchah a ni
- Stem cells hi "master" cells an ni a, taksa chhunga cell chi hrang hrangah an chang thei a ni.
- Tunah hian hengte hi hlawhtling taka hman a ni a, thisen cancer, leukemia ang chi bone marrow transplant atan pawh pawm a ni ber.
- Parkinson’s, zunthlum, leh thinlung natna ang chi natna hrang hrangte tana stem cell therapies hi research stage-ah a la awm a, routine treatment atan pawh hman a la ni lo.
- Private institution ṭhenkhat chuan research-level treatment an pe tih sawi mah se, an himna leh hlawhtlinna chu a chiang thei lo.
- Stem cell enkawlna eng pawh chungchanga thutlukna i siam hmain i doctor thiam tak nen inrawn hmasa la, thurawn dik tak la hmasa phawt ang che.
