A: Iyantlukwano yeeseli zenzeke ngenkqubo ebizwa ngokuba kukwahluka kweeseli. Ngexesha lokwahlula, iiseli ze-embryonic ezingabonakaliyo zifumana iimpawu ezikhethekileyo kunye nemisebenzi. Le nkqubo ilawulwa yintsebenziswano phakathi kweeseli, iimpawu zeekhemikhali kunye nezinto ezithile zofuzo.

Umbuzo: Yintoni ukubaluleka kokwahlukana kweeselula kwezonyango?
A: Ukuqonda ukuhlukahluka kweeseli kubalulekile kwiyeza, njengoko izifo ezininzi zihambelana nokuguqulwa komsebenzi okanye isakhiwo seeseli ezithile. Ngapha koko, ukunyangwa kweeseli ze-stem kunye nokuhlelwa ngokutsha kweeseli zivela njengezicwangciso ezithembisayo zonyango kwizifo ezahlukeneyo.

Umbuzo: Ngaba kukho izifo ezinxulumene nokwahluka kweeseli?
A: Ewe, kukho izifo ezinxulumene nokwahluka kweeseli. Eminye imizekelo ibandakanya umhlaza, apho iiseli ziphulukana namandla azo okwahlula ngokuchanekileyo kwaye ziphindaphindeke ngokungalawulekiyo, kunye nezifo zemfuza, apho kukho utshintsho kwijene elawula ukwahlula kweeseli.

Umbuzo: Ngaba iyantlukwano yeeselula ingatshintshwa?
A: Ewe, iyantlukwano yeeselula inokutshintshwa kwiimeko ezahlukeneyo. Umzekelo, ukuvezwa kwimiba ethile yokusingqongileyo okanye yeekhemikhali kunokubangela utshintsho kukwahlukana kweeseli. Ukongeza, ukuhambela phambili kobugcisa bokuhlelwa ngokutsha kweeseli kuvumela ukuba iiseli zilawulwe ukuze zifumane iimpawu zezinye iindidi zeeseli.

Umbuzo: Ifundwa njani iyantlukwano yeeseli?
A: Uphononongo lweyantlukwano yeeselula lwenziwa ngeendlela ezahlukeneyo, ezifana ne-fluorescence microscopy, i-flow cytometry kunye nokulandelelana kwe-RNA. Ezi ndlela zisivumela ukuba sichonge kwaye sibonakalise iintlobo ezahlukeneyo zeeseli, kunye nokuhlalutya umsebenzi wabo kunye nobudlelwane kunye nezinye iiseli emzimbeni.

Q: Yeyiphi imiceli mngeni ekhoyo ngoku kuphando lweyantlukwano yeeselula?
A: Phakathi kwemiceli mngeni ekhoyo ngoku kuphando lokwahluka kweeseli kukuchongwa kunye nokuchazwa ngokweenkcukacha kwazo zonke iintlobo zeeseli kumzimba womntu. Ngapha koko, ukuqonda indlela iiseli ezisebenzisana ngayo kunye kunye nendlela utshintsho kwiiyantlukwano zamaselula ezinokuthi zibe negalelo kuphuhliso lwezifo zihlala ziphuhlisa iindawo zophando.

Ukuququmbela

Ukuqukumbela, iyantlukwano yeeseli yinto engaphakathi kwaye inomdla kwibhayoloji. Ngobuninzi beentlobo zeeseli kunye nobungcali bazo obusebenzayo, izinto eziphilayo ziyakwazi ukwenza imisebenzi enzima kunye nokugcina i-homeostasis. Uphando kule ndawo lubonakalise ulwazi olubalulekileyo malunga nophuhliso, ukuguga, izifo kunye nokuvuselelwa kwamaselula. Ngaphaya koko, ukuqhubela phambili rhoqo kolandelelwano lwemfuza kunye netekhnoloji yohlalutyo lweeseli enye kusivumela ukuba siqhubele phambili siphonononga kwaye siqonde iyantlukwano yeselula kwezona nkcukacha zinkulu. Njengoko sifunda ngakumbi malunga nobutyebi kunye nobunzima beyantlukwano yeeselula, amathuba amatsha ayavuleka kuphando lwebhayoloji kunye namayeza okuhlaziya. Nangona kunjalo, kuninzi ekufuneka kufunyenwe kwaye kuqondwe, ngoko ke kubalulekile ukuqhubeka nokuxhasa kunye nokukhuthaza uphando kweli candelo linika umdla. Ukwahluka kweeSelluli lisango elikhokelela kwihlabathi lamathuba kunye nolwazi oluya kusenza sibuqonde ngcono ubomi kunye nokuntsonkotha kwabo.
