Xa uzijonga esipilini uze ngequbuliso ubone iinwele ezimbalwa ezingwevu, uziva uxhalabile kwaye ulusizi, akunjalo? Kufuneka ukuba kukho amaxesha amaninzi apho ucinga, "Owu, nam ndimdala ngoku." Kwabanye abantu, iinwele zabo ziqala ukuba ngwevu besebancinci kakhulu, ngamanye amaxesha besesesikolweni. Kutheni oku kwenzeka ngokwenene? Ingaba kungenxa yokuba sikhula? Uphando lwamva nje lwezonyango lufumanise ukuba oku kusenokubangelwa lutshintsho oluncinci emzimbeni wethu olungakhange lucingelwe mntu kuthi.
Zeziphi ezi seli zimangalisayo ezinika iinwele umbala wazo?
Ngamafutshane, iinwele zakho zifumana umbala wazo omhle omnyama nomdaka ngenxa yohlobo olukhethekileyo lweseli ezantsi kweshaft yeenwele zakho. Sizibiza ezi pigment stem cells , okanye ngokuthe ngqo ``Melanocyte Stem Cells - McSCs``. Ezi zezona nxalenye ziphambili zefektri yethu yombala weenwele.
Kodwa ezi stem cells azikwazi ukufaka umbala ngqo kwiinwele. Ukuze zenze loo nto, kufuneka ziqale zikhule zibe "ziimelanocytes." Ezi melanocytes zezo zivelisa umbala onika iinwele umbala wazo.
Ngoko ke isizathu sokuba iinwele zakho zibe sempilweni kwaye zibe mnyama kukuba ezi seli ze-stem ziye zakhula ngokuhamba kwexesha, zaba ziiseli ze-pigment, kwaye zenza umsebenzi wazo ngokufanelekileyo. Okumangalisayo kukuba, ezi seli ze-pigment stem ziphila iminyaka, kodwa ziyafa ngaphambi kwezinye iiseli ezenza umngxuma weenwele. Usenokuba uqaphele ukuba abanye abantu abalahlekelwa ziinwele zabo njengoko bekhula, kodwa iinwele zabo zijike zaba mhlophe ngokupheleleyo. Nasi isizathu. Iiseli ze-hair shaft zisasebenza, kodwa iiseli ezenza umngxuma weenwele ziyekile ukusebenza.
Kuthetha ukuthini 'ukunamathela'? Ukufunyanwa kwamva nje!
Kangangexesha elide, oogqirha kunye nososayensi babecinga ukuba ezi stem cells zihlala kwindawo enye, zivuthwa xa kufuneka, zize zife xa umsebenzi wazo ugqityiwe. Kodwa uphando lwamva nje lutshintshe ngokupheleleyo eli bali.
Okwenzekayo ngokwenene yinto entsonkothileyo nemangalisayo. Ezi seli zifana nenciniba etshintsha umbala. Oko kukuthi, zinokuhamba phakathi kweendawo ezahlukeneyo zeenwele kwaye zitshintshe uhlobo lwazo, endaweni yokuhlala kwindawo enye.
Ngokwale nto intsha ifunyenweyo, ezi seli zisebenza ngokwemijikelo. Oko kukuthi:
1. Inqanaba lokuqala: Ziqala njengee-stem cells ezingavuthwanga.
2. Umsebenzi: Emva koko iya kwenye indawo ye-hair shaft, ivuthwe, ize ivelise imibala enika iinwele umbala wazo.
3. Uhambo lokubuyela: Xa umsebenzi ugqityiwe, ezo seli zibuyela kwimeko yazo yokuqala, oko kukuthi, imeko yeeseli ezisisiseko , kwaye zibuyela kwindawo yazo yokuqala.
Lo gama nje olu mjikelo luqhubeka, iinwele zethu ziya kufumana umbala.
Iphi ke ingxaki?
Abaphandi bafumanise ukuba njengoko sikhula, ezi seli zibalulekileyo ngamanye amaxesha zinamathela kwindawo engafanelekanga kwi-hair shaft. Zinamathela kwinxalenye ye-hair shaft ebizwa ngokuba yi-follicle bulge. Xa zinamathela, azikwazi ukuphinda zigqibezele umjikelo wazo, oko kuthetha ukuba azikwazi ukuvuthwa zenze i-pigment.
Isiphumo? I-shaft yeenwele ezintsha ayifumani mbala. Ngoko ke iphuma imhlophe okanye ingwevu.
Masiyichaze ngakumbi le nkqubo.
| Inkqubo | Yintoni enye (nje) |
|---|---|
| Iinwele eziselula ezisempilweni | Ii-stem cells (ii-McSC) ziyafuduka ngokuchanekileyo, zivuthwe (zibe zii-Melanocytes), kwaye zinike umbala kwiinwele. Emva koko zibuyela kwimeko yazo yokuqala. Lo mjikelo uyaqhubeka. |
| Xa ukhula/xa iinwele zakho zijika zibe mhlophe | Ezinye iiseli ze-stem zinamathela kwinxalenye ye-hair shaft ebizwa ngokuba yi-'bulge'. Azikwazi ukuhamba phambili okanye ukukhula. |
| Iziphumo zokugqibela | Ngenxa yokuba kungekho ziseli zokuvelisa umbala, iinwele ezisandula ukukhula zimhlophe okanye zingwevu. |
Ingaba oku kunika ingcaciso malunga nomhlaza?
Ewe. Oku kufunyaniswe kungabalulekile kungekuphela nje ekugugeni kweenwele, kodwa nasekuqondeni umhlaza wolusu . Ngokukodwa, uhlobo lomhlaza wolusu olubi kakhulu , i-melanoma , luvela kwezi seli zepigment (melanocytes).
Enye yezona mpawu ziyingozi zeeseli zomhlaza we-melanoma kukukwazi kwazo ukutshintsha ngokulula uhlobo lwazo. Kwizonyango, oku kubizwa ngokuba yi -'plasticity' . Olu buchule yingakho umhlaza we-melanoma kunzima ukuwulawula kwaye unyangeke ngokupheleleyo.
Olu phando lutsha lubonisa ukuba iiseli zethu zepigment eziqhelekileyo nezisempilweni nazo zinomlinganiselo ophezulu 'we-plasticity'. Ngoko ke, izazinzulu ngoku zicinga ukuba le ndlela iyingozi yokuziphatha kweeseli zomhlaza we-melanoma isenokuba ibangelwa 'kukwazi ukutshintsha' kwiiseli zepigment eziqhelekileyo ngokwazo, apho zivela khona.
Ngaba ke kuya kwenzeka ukufumana unyango lwale nto?
Lo ngumbuzo osezingqondweni zomntu wonke. Ngoku ekubeni le nkqubo 'ibambekile' ifunyenwe, injongo elandelayo yabaphandi kukufumana indlela yokukhulula ezi seli zibambekileyo nokuzibuyisela kwindawo yazo efanelekileyo . Ukuba oko kungenziwa, kungenza iinwele zingabi ngwevu, kwaye mhlawumbi kwenze kube nzima nokuguqula iinwele zibe mnyama kwakhona.
Kodwa oku kusesekwinqanaba lophando. Akukho nyango loku okwangoku. Nangona kunjalo, kukho iingxelo zabantu abathile abaneenwele ezingwevu eziphinde zaba ngwevu ngenxa yamayeza anikwa ezinye izifo. Mhlawumbi loo mayeza 'akhulula' ezi seli zivalelekileyo ngengozi.
Sikwafuna ukuphanda ngakumbi ukuba izinto ezifana noxinzelelo kunye nokutshaya ziyayichaphazela na into yokuba ezi seli zivaleleke, kuba siyazi ukuba ezi zinto zichaphazela kakubi iinkqubo ezininzi emzimbeni.
Umyalezo Wokuya Ekhaya
- Eyona nto iphambili ebangela ukuba iinwele zakho zibe mhlophe kukuba iiseli zesiqu ezikhethekileyo ezinika umbala weenwele, ezibizwa ngokuba ziiMelanocyte Stem Cells, 'zinamathele' kwindawo engafanelekanga kwi-hair shaft.
- Olu luvumbululo olutsha lwesayensi. Abaphandi bazama ukufumana unyango olunokukhulula ezi seli zivalelekileyo kwaye luthintele iinwele ukuba zingabi ngwevu.
- Okwangoku, akukho yeza lithile elinokuthintela iinwele ukuba zingabi ngwevu. Lumka malunga nezinto ezikhoyo kwimarike.
- De kubekho unyango oluchanekileyo olufumanekayo, ukwamkela imikhwa enempilo efana nokutya ukutya okunesondlo, ukuphepha ukutshaya, kunye nokulawula uxinzelelo kuya kunceda impilo yakho iyonke kunye nempilo yeenwele zakho.
- Ukuba ubona utshintsho olungaqhelekanga nolungaqhelekanga eluswini okanye ezinweleni zakho (umz., amabala amatsha, ukuba ngwevu ngokukhawuleza), musa ukoyika, kodwa qiniseka ukuba ubona ugqirha wakho ukuze akunike icebiso.
