• Nā ʻano o nā hunaola kū
• Pehea e hana ai i ka mālama ʻana i ka cell cell
• No ke aha e mālama ai i nā pūnaewele koʻokoʻo?
• Nā pōmaikaʻi o ka mālama ʻana i nā hunaula koʻokoʻo

ʻO nā pūnaewele nā ​​pūnana i hana ʻole i ka hoʻokaʻawale ʻana o ka ʻola a loaʻa ka hiki no ka hana hou ʻana iā ia iho a hoʻomaka i nā ʻano ʻokoʻa o nā hunaola, e hopena ana i nā pūnaewele loea i kuleana no ka hoʻokumu ʻana i nā ʻano like ʻole o ke kino.

Ma muli o ko lākou hiki no ka hoʻoponopono hou ʻana iā ia iho a me ka loea ʻana, hiki ke hoʻohana ʻia nā hunaola kūmole i ka mālama ʻana i nā ʻano maʻi like ʻole, e like me ka myelofibrosis, thalassemia a me ka anemia maʻi maʻi maʻi, no ka laʻana.

Nā ʻano o nā hunaola kū

Hiki ke hoʻokaʻawale ʻia nā hunaola i ʻelua ʻano nui:

1. Nā pūnaewele kūmole Embryonic: Hoʻokumu ʻia lākou i ka hoʻomaka o ka ulu ʻana o ka embryonic a he nui ka mana o ka hoʻokaʻawale ʻana, hiki ke hāpai i kekahi ʻano keena, nā hopena i ke kūkulu ʻia ʻana o nā hunaola kūikawā;
2. Nā hunaola ʻaʻohe embryonic a i ʻole nā ​​mākua: ʻO kēia nā pūnaewele i hana ʻole i ke kaʻina hana ʻokoʻa a he kuleana no ka hoʻohou hou ʻana i nā āpau i ke kino. Hiki ke loaʻa kēia ʻano keʻa ma nā wahi āpau o ke kino, akā ʻo ka mea nui i ka umbilical cord a me ka iwi iwi. Hiki ke hoʻokaʻawale ʻia nā pūnaewele kūpuna i ʻelua mau hui nui: hematopoietic stem cells, ke kuleana no ka hoʻāla ʻana i nā hunaola koko, a me nā keena mesenchymal, kahi e hoʻoulu ai i ka cartilage, nā mākala a me nā olonā, no ka laʻana.

Ma waho aʻe o nā hunaola embryonic a me nā mākua makua, aia kekahi i loko o nā pūnaewele i hoʻokomo ʻia, ʻo ia nā mea i hana ʻia i ka hale hana a hiki ke hoʻokaʻawale i nā ʻano ʻāpana like ʻole.

Pehea e hana ai i ka mālama ʻana i ka cell cell

Aia nā hunaola kūlohelohe i ke kino a pono no ka hana ʻana i nā hunaola hou a me ka hoʻōla hou ʻana o nā aʻa. Hoʻohui ʻia, hiki iā lākou ke hoʻohana e mālama i nā maʻi like ʻole, nā mea nui i:

• Maʻi ʻo Hodgkin, myelofibrosis a i ʻole kekahi ʻano leukemia;
• Beta thalassemia;
• Anemia maʻi maʻi maʻi;
• Maʻi ʻo Krabbe, maʻi ʻo Günther a i ʻole maʻi Gaucher, nā maʻi e pili ana i ka metabolism;
• Immunodeficiencies e like me Chronic Granulomatous Disease;
• Nā hemahema e pili ana i ka iwi kuamoʻo e like me kekahi ʻano anemia, neutropenia a i ʻole Evans Syndrome;
• Osteopetrosis.

Hoʻohui ʻia, ua hōʻike ʻia kekahi mau noiʻi e hiki ke hoʻohana ʻia nā hunaola kūmole i ka mālama ʻana i nā maʻi ʻaʻohe lāʻau lapaʻau a i ʻole nā ​​lawelawe kūpono, e like me Alzheimer, Parkinson's, Cerebral Palsy, AIDS, Rheumatoid Arthritis a me Type 1 Diabetes. Hana ʻia ka mālama ʻana i ke koʻokoʻo paʻa.

No ke aha e mālama ai i nā pūnaewele koʻokoʻo?

Ma muli o ka hiki ke hoʻohana ʻia i ka mālama ʻana i nā ʻano maʻi like ʻole, hiki ke ʻohiʻohi a mālama ʻia nā pūnaʻi koʻokoʻo i nā mahana haʻahaʻa haʻahaʻa a hiki ke hoʻohana ʻia e ka pēpē a i ʻole ka ʻohana ke pono.

Kāhea ʻia ke kaʻina hana o ka ʻohiʻohi ʻana a mālama ʻana i nā hunaula kumu i ka cryopreservation a me ka makemake e ʻohi a mālama i kēia mau huna pono ma mua o ka lawe ʻana. Ma hope o ka lawe ʻana, hiki ke kiʻi ʻia nā hunaola o ke pēpē mai ke koko, umbilical cord a i ʻole ka iwi iwi. Ma hope o ka hōʻiliʻili ʻana, mālama ʻia nā pūnaewele koʻokoʻo i nā mahana maikaʻi haʻahaʻa haʻahaʻa loa, e ʻae iā lākou e loaʻa i kēlā me kēia manawa no 20 a 25 mau makahiki paha.

Mālama mau ʻia nā keena ʻo Cryopreserve i loko o nā keʻena hoʻokolohua loea i ka histocompatibility a me ka cryopreservation, kahi e hāʻawi mau ai i nā hoʻolālā uku no ka mālama ʻana i nā keena no 25 mau makahiki, a i ʻole i kahi panakō lehulehu ma o ka papahana BrasilCord Network, kahi i hāʻawi ʻia ai nā hunaola i ke kaiāulu, a hoʻohana ʻia no ka mālama ʻana i ka maʻi a noiʻi paha.

Nā pōmaikaʻi o ka mālama ʻana i nā hunaula koʻokoʻo

Hiki ke kōkua ʻia ke mālama ʻana i nā huna puʻupuʻu o kāu pēpē e mālama i nā maʻi i loaʻa i ka pēpē a i ʻole kona ʻohana pili. No laila, nā mea maikaʻi o ka cryopreservation:

1. Pale i ka pēpē a me ka ʻohana: inā pono kahi transplant o kēia mau hunaola, hoʻoliʻiliʻi kā lākou mālama ʻana i nā manawa o ka hōʻole ʻia no ka pēpē, a aia pū kekahi hiki ke hoʻohana ʻia e mālama i kekahi lālā ʻohana pono e pono ai, e like me kaikunāne a i ʻole hoahānau, no ka laʻana.
2. Hiki i ke loaʻa koke ʻana o ka pūnaewele no ke kanu ʻana inā pono;
3. Nā hana hōʻiliʻili maʻalahi a ʻeha hoʻi, hana koke ʻia ma hope o ka hānau ʻana a ʻaʻole kumu ʻeha i ka makuahine a pēpē paha.

Hiki ke kiʻi ʻia nā hunaola like ʻole ma o ka iwi iwi, akā ʻoi aku ka liʻiliʻi o ka loaʻa ʻana o kahi mea kōkua kūpono, he mea hoʻohui i ke kaʻina hana e ʻohiʻohi i nā hunaola, aia kahi pilikia, e koi ana i ke ʻoki.

ʻO Cryopreservation o nā cell stem i ka wā hānau hānau kahi lawelawe i hiki ke loaʻa i ke kumu kūʻai kiʻekiʻe a me ka hoʻoholo e hoʻohana i kēia lawelawe a i ʻole ʻaʻole e kūkākūkā ʻia me ke kauka, i hiki i nā mākua hou ke hoʻoholo pono loa no kā lākou pēpē. Hoʻohui ʻia, ʻaʻole lawelawe nā pūnaewele koʻokoʻo e mālama wale i nā maʻi o ka wā e hiki mai ana i ka pēpē, akā hiki ke mālama i nā maʻi o nā lālā o ka ʻohana pololei, e like me ke kaikaina, makuakāne a i ʻole hoahānau.
