Ua lohe paha ʻoe i ka huaʻōlelo ' Stem Cells ' ma kekahi wahi. Malia paha ma kahi kiʻiʻoniʻoni, ma kahi nūpepa, a i ʻole ma ka pūnaewele. Wahi a kekahi hiki i kēia ke ho'ōla i kekahi maʻi. Wahi a kekahi he mea weliweli iki ia. No laila he aha kēia mau cell stem? He mea maoli anei kēia e hoʻololi i ka wā e hiki mai ana o ka lāʻau lapaʻau? E kamaʻilio kākou e pili ana i ia mea me ka pololei, me ka maʻalahi loa, i kēia lā.
I ka ʻōlelo maʻalahi, he aha kēia mau hunaola kumu?
E noʻonoʻo i kahi pōpō lepo. Hiki iā kākou ke hana i kekahi mea mai kēlā pōpō lepo, e like me ka pēpē, ka ipu hao, kahi holoholona. Pēlā ke ʻano o nā cell kumu. ʻO kēia nā 'master cells' a i ʻole 'master cells' i loko o ko kākou kino. Loaʻa i kēia mau cell ʻelua mau hiki kupaianaha.
1. Ke hana ʻana i nā pūnaewele kumu hou aʻe (Hoʻoulu hou iā ia iho): Hiki i kahi pūnaewele kumu hoʻokahi ke māhele a hana i nā pūnaewele kumu hou aʻe o ke ʻano like.
2. Hoʻokaʻawale ʻana: ʻO kēia ka hiki kupaianaha loa. Hiki i kēia mau cell kumu ke hoʻololi i kekahi ʻano cell kūikawā e pono ai ko mākou kino. No ka laʻana, hiki iā lākou ke lilo i mau cell koko , nā cell lolo ( neurons ), nā cell ʻiʻo puʻuwai, nā cell ʻili , nā cell iwi , a pēlā aku.
ʻAʻohe ʻē aʻe o ko kākou kino i loaʻa kēia hiki. ʻO ia ke kumu e hoihoi nui ai nā kauka a me nā ʻepekema i kēia mau cell kumu.
No ke aha he mea nui nā pūnaewele kumu?
Manaʻo nā kānaka ʻepekema e hiki i ka hiki o kēia mau cell ke hana i kahi ʻokoʻa nui i ka lāʻau lapaʻau e hiki mai ana. He mea nui lākou no ʻekolu mau kumu nui.

Pehea lā ka maikaʻi inā hiki iā kākou ke hoʻohana i nā pūnaewele kumu e hana i nā pūnaewele ʻiʻo puʻuwai hou a hoʻoili iā lākou i loko o ka ʻāpana maʻi? Ua kapa ʻia kēia he lāʻau lapaʻau regenerative . ʻO ia hoʻi ka hoʻoponopono ʻana a i ʻole ka hana hou ʻana i nā ʻiʻo a i ʻole nā ʻōpū i hōʻino ʻia. |

Hiki i kēia ke hāʻawi i kahi ʻike maikaʻi aʻe ma mua o ka hoʻāʻo ʻana ma luna o nā kānaka. |
He aha nā ʻano nui o nā pūnaewele kumu?
ʻO ka mea nui, ke kamaʻilio nei mākou e pili ana i ʻelua ʻano o nā cell kumu.
1. Nā Kelepona Kumu Embryonic
ʻO kēia nā pūnaewele 'super' hiki ke hana i nā mea āpau. E like me ka inoa e hōʻike nei, loaʻa lākou mai nā embryos. ʻO ke kikoʻī, loaʻa lākou no ka noiʻi ʻana mai nā embryos i hoʻohana ʻole ʻia ma hope o ka hoʻoulu ʻana i loko o ka vitro ( IVF ) a laila hoʻohana ʻia (me ka ʻae piha ʻana o nā mākua).
ʻO kekahi inoa no kēia mau pūnaewele he mau pūnaewele "pluripotent". ʻO ia hoʻi, hiki iā lākou ke lilo i kekahi ʻano pūnaewele i loko o ke kino. Ma muli o kēia hiki palena ʻole, loaʻa iā lākou ka hiki ke hoʻoponopono i nā ʻiʻo i hōʻino ʻia e ka maʻi. Eia nō naʻe, no ka mea ua loaʻa mai lākou mai nā embryos, aia kekahi mau hoʻopaʻapaʻa pono ma ka honua e pili ana i kēia.
2. Nā Kelepona Kumu Pākeke
ʻOiai ka inoa "mākua," aia kēia mau pūnaewele i loko o ke kino o nā pēpē, nā keiki, a me nā mākua āpau. Akā, ʻaʻole lākou i like ka ikaika me nā pūnaewele kumu embryonic. Loaʻa pinepine lākou i nā ʻāpana liʻiliʻi i loko o nā ʻiʻo like ʻole, e like me ka iwi iwi, ka ʻili, ka lolo, a me ke akepaʻa.
ʻO ka maʻamau, hana nā pūnaewele kumu makua i nā pūnaewele kūikawā i nā ʻiʻo a lākou e noho nei. No ka laʻana, hiki i kahi pūnaewele kumu i loko o ka ʻili ke hana i nā pūnaewele ʻili hou, akā ʻaʻole nā pūʻuwai puʻuwai.
ʻO ka holomua hou loa i ka ʻepekema: nā pūnaewele iPS
Ua ʻike nā kānaka ʻepekema i kahi mea kupaianaha. Hiki iā lākou ke lawe i kahi cell maʻamau e ulu ana e like me ko kākou ʻili a 'hoʻolālā hou' iā ia i loko o ka hale hana e hana e like me kahi cell kumu embryonic. Ua kapa ʻia kēia mau mea he mau cell kumu pluripotent induced (iPS cells) . Ua wehe kēia i kahi manawa kūpono e hana i ka noiʻi me ka ʻole o nā pilikia pono e pili ana i nā embryos.
He aha nā lāʻau lapaʻau e hoʻohana ʻia nei me nā cell stem?
ʻO kēia ka mea a ka poʻe he nui e makemake ai e ʻike. Maanei pono mākou e hoʻomaopopo pono i ka ʻokoʻa ma waena o nā lāʻau lapaʻau e hoʻohana pono ʻia nei a me nā lāʻau lapaʻau e manaʻo ʻia ana i ka wā e hiki mai ana .
Nā lāʻau lapaʻau i ʻae ʻia a hoʻohana ʻia i kēia manawa
ʻO ka lāʻau lapaʻau cell kumu maʻamau a holomua hoʻi i ka honua i kēia lā, ʻo ia ka hoʻoili cell kumu koko. Ua lohe paha ʻoe i kēia ma ke ʻano he 'bone marrow transplant'.
Hoʻohana nui ʻia kēia lāʻau lapaʻau no:
- No nā maʻi ʻaʻai koko (e.g. Leukemia, Lymphoma)
- No kekahi mau maʻi koko (e.g. 'Sickle cell anemia')
- No ke kūkulu hou ʻana i ka iwi i luku ʻia e ka chemotherapy no ka maʻi kanesa
No kēia kumu, loaʻa nā pūnaewele kumu mai ka iwi iwi o kahi mea hāʻawi olakino, a i ʻole mai ke koko o ke kaula umbilical i ka wā e hānau ai ke keiki.
Nā manaʻolana e hiki mai ana a me ka holomua o ka noiʻi
Manaʻolana nā kānaka ʻepekema e hoʻohana pono ʻia nā lāʻau lapaʻau cell stem no nā maʻi he nui i ka wā e hiki mai ana. He mea nui e hoʻomanaʻo ʻia aia nō kēia mau mea i ke kahua noiʻi .
- ka maʻi o Parkinson
- ka maʻi o Alzheimer
- Maʻi diabetes
- Maʻi puʻuwai
- Nā ʻeha o ke kaula kuamoʻo
- ʻO ka ʻāʻī o ke kino
He mea nui: Inā ʻōlelo kahi hui "hōʻoiaʻiʻo ia i ka lāʻau lapaʻau cell stem" no kēia mau maʻi, e noʻonoʻo hou. ʻAʻole i ʻae ʻia kēia mau mea ma ke ʻano he mau lāʻau lapaʻau maʻamau. E kūkākūkā i kekahi mea me kāu kauka.
Palekana anei kēia mau lāʻau lapaʻau? Aia kekahi mau pilikia?
E like me nā ʻenehana lapaʻau hou a pau, he mau pilikia a me nā pilikia ko ka lāʻau lapaʻau cell stem. Ua ʻike maikaʻi nā kānaka ʻepekema i kēia mau mea a ke hana nei lākou e ʻimi i nā hopena no lākou.
- Ka pilikia o ka maʻi ʻaʻai:Ma muli o ka hiki i nā pūnaewele kumu ke māhele wikiwiki, hiki iā lākou ke māhele i kekahi manawa me ka ʻole o ke kaohi ʻia a hana i nā puʻupuʻu.
- Ka pōʻino hoʻoilina: Aia kahi hiki ke hōʻino ʻia nā cell i ulu ʻia i loko o ka hale hana hoʻokolohua.
- Ka hōʻole ʻana o ka ʻōnaehana pale: Hiki i ko kākou ʻōnaehana pale ponoʻī ke hoʻouka i nā cell i hāʻawi ʻia mai waho o ke kino, e mālama ana iā lākou he 'ʻenemi haole'.
- Nā pilikia o ke ʻano lapaʻau: Nā pilikia e pili ana me nā kaʻina hana ʻoki e loaʻa ai a hoʻokomo paha i nā cell (e.g., nā inikini i loko o ka lolo, ka puʻuwai).
Ke hoʻomau nei ka noiʻi ʻana e hōʻemi i kēia mau pilikia. No laila, ʻo ka loaʻa ʻana o ia mau lāʻau lapaʻau mai nā kumu i ʻae ʻole ʻia a maikaʻi ʻole paha he mea weliweli loa ia.
Leka Lawe-Home
- He ʻano kūikawā o ke 'kelepona haku' nā pūnaewele kumu i hiki ke lilo i kekahi pūnaewele i loko o ke kino. He nui ko lākou hiki i ka lāʻau lapaʻau.
- I kēia manawa, ʻo ka hoʻōla ʻana o nā cell stem ka mea i hoʻohana nui ʻia a kūleʻa loa no nā maʻi kanesa koko e like me ka leukemia a me kekahi mau maʻi koko.
- Aia nō nā lāʻau lapaʻau no nā kūlana e like me ka maʻi diabetes, ka maʻi Parkinson, a me ka maʻi puʻuwai i ke kahua noiʻi a ʻaʻole i ʻae ʻia no ka hoʻohana maʻamau.
- Ma mua o kou manaʻoʻiʻo ʻana i kekahi mea āu e ʻike ai ma ka pūnaewele a i ʻole ma kahi ʻē aʻe e pili ana i ka lāʻau lapaʻau cell stem, e nīnau pono i kāu kauka a i ʻole kekahi loea lapaʻau kūpono e pili ana i ia mea.
- E makaʻala loa i nā "keʻena lapaʻau cell kumu" i ʻae ʻole ʻia a ma lalo o ke kūlana. Mai hoʻoweliweli i kou olakino.
