Ufuna ukhathalelo olululo kunye nokusombulula iingxaki zolusu
Emva koko kufuneka sifake amandla amatsha kwiiseli
Iimveliso zokunakekelwa kwesikhumba ezisebenzisa izithako ezisebenzayo ukufikelela nzulu eluswini
Kufana nomthi ofunxa amanzi
Izondlo namanzi kufuneka afikelele ezingcanjini ukuze achume.
Ukuba izondlo namanzi zihlala phezu komhlaba kuphela
Ngaphandle kokufikelela ezingcanjini, umthi uya kubuna ngokuthe ngcembe.
Izisombululo zokunakekelwa kwesikhumba zemveli
Sebenzisa i-sweat glands kunye ne-pores ukungena kwinyathelo lokugxila
Oko kukuthi, i-high-concentration ngaphandle ingena kwi-low-concentration ngaphakathi.
Kuba le ndlela yokungena iyacotha
Uninzi lweemveliso zokhathalelo lwesikhumba ziza ngohlobo lweepastes
Ukwandisa ixesha imveliso ihlala phezu kwesikhumba
Ngexesha elifanayo, ukwenzela ukwandisa ukunyanzeliswa kwezinto ezisebenzayo
Izixhobo zokungena nazo ziya kongezwa kwimveliso
Ukufihla iphunga lezithako zekhemikhali kwimveliso
Kwakhona yongeza incasa
Izilondolozo zongezwa ukwandisa ubomi beshelufu
Ixesha Lokhathalelo Lolusu Lwebhayoloji—Iiseli Zesiqu
Iiseli zestem ziyaziphindaphinda
kunye neeseli zamandulo ezinamakhono amaninzi okwahlula
Iseli yokuqala yomzimba
Yiseli yokuqala eyenza izicubu ezahlukeneyo kunye namalungu omzimba womntu.
Uphando lwamva nje lwenzululwazi lubonisa
I-Stem cells ayiyoyunithi esisiseko ye-biological evolution kunye nophuhliso
Ikwayiyunithi esisiseko yokukhula kwezicubu kunye namalungu.
Ngexesha elifanayo, ukwenzakala, umonakalo wesifo kunye nokuncipha komzimba
Iyunithi esisiseko yokuvuselela kunye nokulungiswa
Ukuhlaziywa kwe-stem cell kunye nokulungiswa kwendlela
Ngumthetho wehlabathi jikelele kwibhayoloji
Kuphela i-5-10% yeeseli ze-stem emzimbeni womntu zisebenza
I-90-95% eseleyo yeeseli ze-stem
Ukulala kude kube sekupheleni kobomi
Ukubaluleka kokuvula iiseli ze-stem
Ulusu lelona lungu likhulu lomzimba womntu.
Zonke iingxaki zesikhumba zibangelwa ukuhla komsebenzi weeseli
Njengoko sikhula
Inani leeseli imizimba yethu enokusebenza kuzo liyancipha ngokuthe ngcembe
Ngenxa yoko, ukwaluphala kuya kusiba nzulu ngakumbi
Ukuba iiseli ze-stem ezileleyo ziyasebenza ukwenza iiseli ezintsha ezisebenzayo
Oku kwandisa inani leeseli ezinokusebenza
Izinga lokuguga liya kuthotha
Iziphumo zokunakekelwa kwesikhumba kwiiseli ze-stem
①Vuselela iiseli zolusu;
② Ukukhuthaza ukwahlukana kweeseli ze-epidermal basal, ukukhawuleza ukuhlaziya, kunye nokuvuselela i-epidermis kunye neeseli;
③Nyusa i-fibroblasts ukuba ikhuphe i-collagen, yenza ulusu luzele ukunwebeka kunye noxinzelelo, kwaye unciphise imibimbi;
④ Ukukhuthaza ukwanda kweeseli ze-vascular endothelial, ukwandisa ukuhamba kwegazi esikhumbeni, kwaye wenze ulusu lube mhlophe kunye ne-rosy;
⑤ Ukuthintela ukugqithisa kunye ne-melanin ye-melanin kunye nokuphucula ukukhutshwa kwe-melanin;
⑥Ukukhawulezisa imetabolism yeeseli, ngokwenza oko kube nzima kwiimveliso ezahlukeneyo zemetabolism eziyingozi ukuba ziqokelele kwiiseli;
⑦ Ukuphelisa ii-radicals zamahhala kwaye uphathe ukuxhatshazwa kwesikhumba;
⑧Vuselela iiseli ze-stem eluswini ukuvelisa iiseli ezintsha ezininzi ukufezekisa iinjongo zokuchasa ukuguga.
