Research: modabwitsa moyo wosatha?

Anthu kalekale pofunafuna mankhwala a matenda chosafa. Akatswiri asayansi apeza zikusonyeza kuti dziko lathu lokongolali ndi cholengedwa kuti moyo kosatha. Izi Zingaoneke kalekale anaphunzira ndipo onani modabwitsa, kapena kani, cholengedwa waung'ono wotchedwa nutrikula. Kodi mukufuna kuphunzira mmene kupeza modabwitsa moyo kwa muyaya?

chilengedwe utitiri

Medusa nutrikuly padziko lonse lapansi sayansi kwa nthawi yaitali. Malongosoledwe loyamba la nyama anaonekera mu m'ma chakhumi ndi chisanu ndi chinayi. Kubereka ndi mkombero moyo kuchokera nutrikuly wamba ndithu. Ngati modabwitsa onse, umuna umuna kumachitika padziko nyanja, ndiyeno nkutembenuka dzira mu larva a. Ndiye planuly kutsitsa kumachitika pa pansi ndi mapangidwe ndi tizilombo ting'onoting'ono, lomwe ndi wosiyana modabwitsa ting'onoting'ono kuti moyo kwamuyaya. Photos wa zolengedwa zimenezi anapereka m'munsimu.

Kunja view modabwitsa Turritopsis nutricula unremarkable, kani, tikhoza kunena kuti ali wolengedwa kakang'ono. Ndi ambulera m'mimba mwake zosakwana 5 mm, umene wazunguliridwa ndi tentacles woonda. Mu wongobadwa modabwitsa iwo 8 okha, ndiye monga munthu wamkulu ali ku zidutswa 100. alinso chamtanda wofiira malo amene anapanga pakati pa ambulera cha ziwalo m'mimba ya modabwitsa. Akhanda nutrikuly kukula kwa 1 mm.

Kupezeka chodabwitsa

The cha m'ma wotsiriza unali wotchuka ndi anapeza zodabwitsa. Iwo likukhalira kuti modabwitsa moyo wosatha. Anazitulukira Italy Fernando Boero. Kukambirana woyera aiwala kamodzi Aquarium pa, asayansi anapeza tizilombo ting'onoting'ono zachilendo. Izi zophuka zachilendo ooneka ngati modabwitsa amene anafa Aquarium, koma wopanda tentacles. Wasayansi anaganiza kupitiriza zimenezo, pamene zolengedwa zina mu Aquarium ndi anamwalira. Kudzaza ndi madzi a m'nyanja, Boero anaonera tizilombo ting'onoting'ono. Patapita nthawi, iwo anayamba, ndi chifukwa anabadwa modabwitsa ting'onoting'ono nutrikuly.

Pakhala zimaoneka zovuta - nutrikuly anatembenuka mkombero chitukuko. zinadziŵika kuti zonse modabwitsa ndi sitepe wotsiriza kwa nthawi ino - gawo kuswana. Ambiri coelenterates nyama, ndipo osati iwo, kubadwa kwa mazira ndi umuna kapena maselo kumabweretsa imfa ya anthu wamkulu. Ndipo kale pali nyama, modabwitsa mphutsi likule n'kukhala ndi tizilombo ting'onoting'ono, ndi kale amabadwa modabwitsa yaing'ono. Kutsegula Boero chabwerera kudziwa zonse za modabwitsa. Mwachitsanzo, asayansi apeza modabwitsa kuti moyo kwamuyaya.

mayendedwe amoyo

Oimira mtundu uwu, monga mitundu ina ya zamoyo hydroid anayesedwa 2 siteji. Woyamba limayamba ndi chitukuko cha mphutsi pambuyo umuna. Ndiye mphutsi kukhazikika pansi pa nyanja atsekerezedwa mu malo ya tizilombo ting'onoting'ono kuwasandutsa. Choncho, pali madera lonse la modabwitsa maonekedwe chokhala ndi spindle kapena mace. Pa nthawi imeneyi chitukuko cha tizilombo ting'onoting'ono kupanga mtundu wa mafupa, pa chitsiriziro pali chibadidwe ndi tentacles modabwitsa maselo lobaya. Choncho, njuchi lonse angathe kudya nyama yaing'ono.

Mbali yachiwiri ikuyamba ndi kulekana kwa achinyamata modabwitsa tizilombo ting'onoting'ono. Choncho, modabwitsa yaing'ono poyamba kukhala zachilendo kwa ife njira ya moyo. Mu miyezi yochepa chabe, iwo akhwime kugonana, dongosolo lonse akubwereza. Kodi izo zimachitika kuti modabwitsa moyo wosatha? N'zochititsa chidwi kuti modabwitsa ndi njira zina kusunga mitundu.

Features modabwitsa

Kuteteza moyo amagwirizana ndi luso zokhalapo hydroid kwa ndondomeko kuchira. Iwo akhala ankadziwikanso kuti modabwitsa mu nthawi yochepa angathe kubwezeretsa otaika ziwalo. Experimentally anatsimikizira kuti odulidwa powomba modabwitsa amatha kubereka yokha. Zimenezi amatchedwa transdifferentiation kuchira. Ndipotu mtundu wina wa maselo angayambe ena, kutanthauza kuti, theoretically, modabwitsa onse moyo wosatha. Komabe mphamvu zimenezi ndi zinthu zina zambiri. Abuluzi mosavuta kukula wekha mchira watsopano, ndipo ofufuza masiku ano amatha ku maselo tsinde kukula ziwalo payekha.

Koma luso modabwitsa ndi nutrikuly kubwezeretsa thupi lanu lonse ndi wapadera. Iwo amatha kubwereza ndondomeko ya nambala wopandamalire nthawi ndi kukhalapo kosatha wamng'ono. Izi njira napatsa sayansi kopanda kukhulupirira kuti modabwitsa moyo wosatha.

Masiku ano, asayansi wayesetsa kuunikira mtundu uwu modabwitsa kufufuza mwatsatanetsatane dongosolo la rejuvenation. Padziko lathuli chodabwitsa, pali unknowns zambiri anthu zokhalapo amene alibe anawulula zinsinsi zawo.
