Udindo wa stem cell mu biotech komanso zachipatala

Ma cell stem, omwe ali ndi mphamvu ziwiri zodzikonzanso okha komanso kusiyanitsa, ndi ofunikira kwambiri mu gawo la regenerative mankhwala ndi kafukufuku wamankhwala. Maselo amenewa amatha kukhala amitundu yosiyanasiyana, kuwapangitsa kukhala ofunikira kwambiri pakukonzanso ndi kukonza minofu. Kuwongolera kachitidwe ka cell cell kumaphatikizapo njira zovuta za mamolekyulu, zomwe ndizofunikira kuti zisungidwe ndikugwira ntchito.

Mitundu ingapo ya ma cell stem cell, kuphatikiza ma embryonic stem cell (ESCs), induced pluripotent stem cell (iPSCs), mesenchymal stem cell (MSCs), ndi haematopoietic stem cell (HSCs), amapereka njira zochiritsira zosiyanasiyana. Ma ESC amadziwika chifukwa cha kuchuluka kwawo, ma iPSC pakugwiritsa ntchito mankhwala amunthu payekha, ma MSC okonza minofu, ndi ma HSC pochiza matenda amagazi. Maselo amenewa ali patsogolo pa chithandizo chamakono cha matenda osiyanasiyana, kuchokera ku matenda okhudzana ndi magazi mpaka kuvulala kwa mafupa.

Kugwiritsiridwa ntchito kwa maselo a stem kumafikira pakupanga mizere yokhudzana ndi odwala, kutengera matenda, ndi chitukuko cha mankhwala, kusintha. mankhwala mwamtundu ndi njira zothandizira. Pamene gawo la kafukufuku wa stem cell likupita patsogolo, liri ndi lonjezo losintha chithandizo chamankhwala pazochitika zosiyanasiyana, kuphatikizapo matenda a neurodegenerative ndi matenda a shuga, kuwonetsa nyengo yatsopano mu sayansi ya zamankhwala.

Kodi ma stem cell ndi chiyani?

Ma cell cell amatanthauzidwa ndi ntchito ziwiri zofunika: kudzikonzanso ndi kusiyanitsa. Kudzikonzanso kumawathandiza kugawanitsa ndikupanga maselo ambiri, pamene kusiyanitsa kumawathandiza kupanga mitundu yeniyeni ya maselo ofunikira kuti akonze ndi kukonza minofu. Uwiriwu ndi wofunika kwambiri kuti thupi lisinthe. Stem cell amakwaniritsa izi kugawanika kwa asymmetric, pamene selo limodzi limasunga makhalidwe a tsinde ndipo lina limasiyanitsa, kuonetsetsa kuti ma cell a tsinde ndi osiyana amaperekedwa mosalekeza.

Pamlingo wa mamolekyulu, machitidwe a cell cell amayendetsedwa ndi netiweki ya zolembera ndi njira zowonetsera, omwe amawongolera mafotokozedwe a jini ofunikira kuti asunge mawonekedwe awo apadera. Kusokonekera kwa maukondewa kumatha kuyambitsa matenda monga khansa. The stem cell niche, chilengedwe mkati mwa minyewa yomwe ma SC amakhala, amathandizanso kwambiri pakuwongolera machitidwe awo. Niche iyi imapereka zizindikilo zomwe zimakhudza kusamalidwa kwa ma stem cell, kuyambitsa, ndi kusiyanitsa, zomwe zimagwirizana ndi ntchito yawo pakusinthika kwa minofu.

Ma stem cell ndi ofunika kwambiri kutsanzira matenda ndi chitukuko cha mankhwala chifukwa cha kuthekera kwawo kusiyanitsa mitundu yosiyanasiyana ya ma cell. Katunduyu amalola kupanga zitsanzo za matenda zomwe zimapereka chidziwitso pamayendedwe a matenda ndikuyesa mankhwala ochizira. Kumvetsetsa biology ya ma SCs, kuphatikiza kuwongolera kwawo komanso kuyanjana ndi chilengedwe chawo, ndikofunikira kuti pakhale chitukuko chamankhwala obwezeretsanso ndikupanga mankhwala atsopano.

Kugwiritsa ntchito ma stem cell mu zamankhwala

Ntchito zochiritsira za stem cell zimayambira m'magawo angapo azachipatala, zomwe zimatha kukula mosalekeza limodzi ndi kupita patsogolo kwa stem cell biology. Hematopoietic stem cell kumuika akhala chithandizo choyambirira cha matenda osiyanasiyana amagazi ndi khansa. Mumikhalidwe ngati khansa ya m'magazi ndi lymphoma, zoikamo zimenezi zimatsitsimula mphamvu ya thupi yopanga maselo athanzi a magazi mwa kuchotsa m’mafupa owonongeka kapena odwala ndi ma HSC athanzi.

Mesenchymal stem cell (MSCs) akupeza chidwi pazomwe angathe pakukonzanso minofu yowonongeka. Akufufuzidwa kuti agwiritsidwe ntchito ngati osteoarthritis ndi kuvulala kwa msana, ndipo mphamvu zawo zotsutsana ndi kutupa zikufufuzidwa kuti zithandizidwe zatsopano. automatenda a chitetezo cha mthupi. Kuphatikiza apo, ma cell stem cell a mesenchymal ndi ofunikira popanga zitsanzo zama cell kuti aphunzire kusinthika kwa minofu ndi zotsatira zake mankhwala odana ndi kutupa.

Ma cell Stem Cells Opangidwa ndi Pluripotent (iPSCs) ali patsogolo pakusintha mankhwala amunthu. Mwa kukonzanso maselo achikulire kukhala ochulukirachulukira, ma iPSC amathandizira kupanga mizere ya cell yeniyeni ya odwala. Ma Induced Pluripotent Stem Cell awa ndiwothandiza kwambiri popanga ma cellular ophunzirira momwe matenda akuyendera, kuyesa mphamvu ya mankhwala, ndikuwunika chithandizo chamunthu payekha. Ma iPSC amathandizanso kwambiri pakupanga mankhwala, kupereka chithunzithunzi cholondola cha matenda a anthu kuposa nyama zachikhalidwe, chifukwa cha kuthekera kwawo kutsanzira ma cell osiyanasiyana amtundu wa vitro.

Kupitilira izi, ma SC akufufuzidwa mochulukira momwe angathere pochiza matenda osiyanasiyana, kuphatikiza matenda a neurodegenerative, matenda amtima, ndi shuga. Kuthekera kosintha ma cell owonongeka ndi athanzi omwe amachokera ku ma SC kumapereka chiyembekezo chosangalatsa cha chithandizo chamankhwala chamtsogolo.

Mphamvu ya stem cell

Munda wa kafukufuku wa stem cell, wophimba ma embryonic stem cell, iPSCs, mesenchymal stem cell, ndi hematopoietic stem cell, ndi dera lomwe likupita patsogolo mwachangu mu biomedicine. Kupezeka kulikonse kumakulitsa kuthekera kwa ma SC pochiza matenda osiyanasiyana, kusonyeza nyengo yatsopano mu sayansi ya zamankhwala ndi zochizira. Gawo lomwe likupita patsogololi lili ndi lonjezo lotsegula njira zatsopano zochiritsira ndikukulitsa kumvetsetsa kwathu za matenda ovuta, kuyika ma SCs ngati gawo lofunikira pakupita patsogolo kwaukadaulo ndi zamankhwala.

M'munda wovuta kwambiri wopanga mapuloteni ophatikizanso, kusankha kwa zida ndi maukadaulo ogwirizana ndikofunikira. Mayankho athu ali patsogolo pa luso la sayansi yasayansi, yopereka zida zamakono komanso zogwira mtima kwambiri pagawo lililonse la kupanga mapuloteni.

Advanced Bioreactor Technology: Zathu bioreactors ⇀  adapangidwa ndi mawonekedwe apamwamba kwambiri kuti akwaniritse chikhalidwe cha ma cell, kupititsa patsogolo zokolola komanso mtundu wa mapuloteni ophatikizanso. Kuwongolera koyenera kwa magawo a chilengedwe monga kutentha, pH, ndi mpweya wa okosijeni, kuphatikizidwa ndi machitidwe apamwamba owunikira, zimatsimikizira kukula kwabwino kwa maselo ndi mawonekedwe a mapuloteni.
