He kumu no ka ulu hou ʻana i nā lālā kanaka

He nui nā hiʻohiʻona o ka hana hou ʻana i ke aupuni holoholona: nā moʻo a me nā salamanders e ulu hou i nā lālā a me nā huelo i nā manawa a pau, e like me ka iʻa hōkū. https://blogs.scientificamerican.com/guest-blog/regeneration-the-axolotl-story/

Ua kaulana ʻo Planaria (a ʻaʻole makemake paha) nā mea komo no nā hoʻokolohua i ka ulu ʻana i ʻelua poʻo (https://www.youtube.com/watch?v=roZeOBZAa2Q). ʻAʻole makemake mākou e loaʻa i ʻelua poʻo, akā no ke aha e hiki ʻole ai i ke kanaka ke hoʻoulu hou i nā ʻōpū, nā lima a me nā wāwae i nalowale? 

ʻOiai ʻo kekahi o nā pūnaewele i loko o ko mākou kino e loaʻa i nā mana regenerative - hoʻōla ka ʻili, ka uhi o ko mākou ʻōpū, ko mākou ate - hana lākou pēlā ma ke ʻano palena. ʻO ka credo maʻamau i ka biology ʻo ia ka ʻoi aku o ka hana kūikawā o ke kelepona a i ʻole ka ʻiʻo, ʻoi aku ka liʻiliʻi o kona hiki ke ulu hou. Ke piʻi nei nā kānaka i ke alapiʻi evolutionary, ua hele ka nui o kā mākou mau cell i ka ʻokoʻa o ka hoʻi ʻole: hiki iā ʻoe ke ulu i kekahi o kou lauoho i hope, akā ʻo ka manamana lima i ʻoki ʻia he kumu.

ʻO kā mākou ʻike e hoʻonui nei i nā pūnaewele stem-a me ko lākou hiki ke hoʻokaʻawale-- ua hiki ke hana hou i ka ʻiʻo paʻakikī. ʻO kaʻoiaʻiʻo, ua hōʻoia ʻo Kauka Levin i kāna hana i nā hōʻailona bioelectric e hoʻoulu i ka ʻokoʻa o ka cell a me ka kiko. E heluhelu e pili ana i kona kūleʻa i ka hoʻoulu hou ʻana i ka uila i nā amphibian: https://www.popsci.com/body-electrician-whos-rewiring-bodies

ʻO ka lima a i ʻole ka wāwae he hui paʻakikī o ka ʻili, iwi, ʻiʻo, aʻalolo a me nā ʻiʻo vascular i loaʻa nā hana like ʻole. ʻO ka maalea ka loaʻa ʻana o nā hōʻailona kūpono e hoʻoulu i ka cell progenitor kūpono i ka ulu ʻana i kēia mau hale kikoʻī.

Ke wehe ʻia kēia mau hōʻailona, ​​​​ʻo ke koena o ke ala e hoʻomau ai i kēia kaʻina hana - a pili ia i ke kūʻē ʻana i kā mākou hana ho'ōla maoli. Ke ʻike ke kino i ka ʻeha, hoʻāʻo ʻo ia e hoʻopaʻa i nā wahi i ʻike ʻia ma ka hoʻolei ʻana i ka collagen i loko o ka wahi i lilo i ʻiʻo ʻili. Hiki paha kēia i ka pani ʻana i ka ʻeha, akā hāʻawi ia i ka wahi i ʻeha i kahi hopena hana ʻole.

ʻO kahi hoʻonā ka mālama ʻana i ka wahi 'ho'ōla' i loko o kahi kaiapuni hermetic kahi e kūpono ai ka ulu ʻana o ka ʻiʻo. ʻO ka mālama ʻana i ka lālā e ulu ana i loko o kēia 'ʻauʻau waiʻai' portable e hāpai i ke kaʻina hana ho'ōla me ka mālama ʻana iā ia mai ka maʻi a i ʻole ka ʻeha.
