Malinga ndi zotsatira za kafukufuku wa mabungwe ovomerezeka padziko lonse lapansi, matenda ndi senescence ya thupi la munthu imayambira kuwonongeka kwa maselo. Kuthekera kwa maselo kuti adzipangenso okha kudzachepa ndi kukula kwa zaka. Maselo okalamba ndi matenda akamapitiriza kuwunjikana, maselo atsopano sangathe kuwaloŵa m’malo mwa nthaŵi, ndipo matenda ndi senescence zimachitika mosapeŵeka.
Maselo a tsinde ndi mtundu wapadera wa selo m'thupi lomwe lingathe kusandulika kukhala mtundu uliwonse wa selo m'thupi lathu, lomwe limagwiritsidwa ntchito kukonzanso zowonongeka ndikusintha maselo okalamba. M'zaka zaposachedwa, ndikukula kwa lingaliro la chithandizo cha stem cell ku matenda ndi anti-aging effect, stem cell cryopreservation yakhala chisankho chofunikira pa thanzi lamtsogolo la anthu ambiri.
Nthawi Yosungirako Ma Stem Cells mu Liquid Nitrogen System
Mwachidziwitso, kusungidwa kwa nayitrogeni wamadzimadzi kumatha kusunga ma cell kwamuyaya. Pakalipano, chitsanzo cha cell chodziwika chautali kwambiri chosungidwa mu labotale ya Chinese Academy of Sciences chasungidwa kwa zaka 70. Izi sizikutanthauza kuti kusungirako kwachisanu kumatha kuchitidwa kwa zaka 70 zokha, koma chitukuko cha mafakitale onse chimakhala ndi mbiri ya zaka 70 zokha. Ndi chitukuko cha The Times, nthawi ya ma cell tsinde owumitsidwa idzakulitsidwa mosalekeza.
Zoonadi, nthawi ya cryopreservation imadalira kutentha kwa cryopreservation, monga cryopreservation yakuya yokha yomwe ingapangitse maselo kugona. Nthawi yabwino, imatha kusungidwa kwa maola 5 kutentha kwapakati. Kutentha kochepa 8 digiri Celsius kumatha kusungidwa kwa maola 48. Mafiriji ozama otsika kwambiri -80 digiri Celsius amatha kusungidwa kwa mwezi umodzi. Nayitrogeni wamadzimadzi amakhala wokhazikika pa -196 digiri Celsius.
Mu 2011, zotsatira za kuyesa kwa in vitro ndi nyama zomwe zidasindikizidwa mu Magazi ndi Pulofesa Broxmeyer ndi gulu lake ku yunivesite ya Indiana, yemwe ndi katswiri pa kafukufuku wa chingwe BLOOD stem cell biology, adatsimikizira kuti ma cell a stem cell omwe amasungidwa kwa zaka 23.5 amatha kukhalabe ake enieni. kuthekera kwa kuchuluka kwa in vitro, kusiyanitsa, kukulitsa komanso kuyika kwa vivo.
Mu 2018, cell stem cell yomwe inasonkhanitsidwa ku Beijing Obstetrics and Gynecology Hospital inazizira kwa zaka 20 ndi miyezi 4 mu June 1998. Pambuyo potsitsimutsa, ntchitoyi inali 99.75%!
Pakalipano, pali oposa 300 mabanki a magazi padziko lapansi, ndi 40 peresenti ku Ulaya, 30 peresenti ku North America, 20 peresenti ku Asia ndi 10 peresenti ku Oceania.
Bungwe la World Marrow Donor Association (WMDA) linakhazikitsidwa mu 1994 ndipo lili ku Leiden, Netherlands. Yaikulu kwambiri ndi National Marrow Donor Programme (NMDP), yomwe ili ku Minneapolis, Minn., ndipo inakhazikitsidwa mu 1986.DKMS ili ndi opereka ndalama pafupifupi 4 miliyoni, kupereka oposa 4,000 chaka chilichonse. Chinese Marrow Donor Program (CMDP), yomwe idakhazikitsidwa mu 1992, ndi banki yayikulu yachinayi pambuyo pa United States, Germany ndi Brazil. Amatha kusiyanitsa mitundu ina ya maselo a magazi, monga maselo ofiira a magazi, maselo oyera a magazi, mapulateleti ndi zina zotero.
Liquid Nayitrojeni System Yosungira Ma cell Stem
Makina osungira ma cell cell amakhala ndi thanki yayikulu yamadzimadzi ya nayitrogeni cryogenic, makina opopera a vacuum (kuphatikiza chitoliro cha vacuum jacket, vacuum jacketed hose, cholekanitsa gawo, vacuum jacketed stop valve, chotchinga chamadzimadzi, etc.) chidebe chachilengedwe chosungiramo zitsanzo za ma stem cell mu thanki.
Nayitrogeni wamadzimadzi amapereka chitetezo chotsika kutentha kosalekeza muzotengera zachilengedwe. Chifukwa cha mpweya wachilengedwe wa nayitrogeni wamadzimadzi, nthawi zambiri ndikofunikira kudzaza zotengera zamoyo kamodzi pa sabata kuwonetsetsa kuti kutentha kwa chidebe chachilengedwe ndikotsika kokwanira.
HL Cryogenic Equipment
HL Cryogenic Equipment yomwe idakhazikitsidwa mu 1992 ndi mtundu womwe umagwirizana ndi Chengdu Holy Cryogenic Equipment Company ku China. HL Cryogenic Equipment yadzipereka kupanga ndi kupanga High Vacuum Insulated Cryogenic Piping System ndi Zida Zothandizira Zogwirizana.
