Iiseli zemithambo-luvo yokuvuselela?

Xa abantu, kukho ezingaphezu kwesinye elinamanci billion iiseli zemithambo-luvo. Ngamnye kubo luquka iinkqubo kunye umzimba - ngokuqhelekileyo luvo eziliqela, emifutshane branched, kunye yemithambo-nye. iinkqubo ikhutshwa phandle ngokuqhagamshelana luvo kunye nabanye. Ngenxa yoko kwasekwa izangqa kunye nothungelwano kunye apho kwegazi ukubetha. Ukususela kumaxesha amandulo, izazinzulu baxhalabile malunga nokuba iiseli zemithambo-luvo ukuba ukuntshula.

Kuyo yonke impilo yengqondo ulahlekelwa iiseli zemithambo-luvo. Le ukufa izakhi ihlelwa. Nakuba kunjalo, ngokungafaniyo nezinye iiseli, oko akuthethi ukuba ukwabelana namandla. Kwiimeko ezinjalo, uqala ukwenza indlela eyahlukileyo. Imisebenzi iiseli ezilahlekileyo baqale ukwenza ekufutshane, apho, ukwandisa ubukhulu, baqale ukwakha uxhulumaniso ezintsha. Ngenxa yoko, neyalo ukushiywa zemithambo-luvo ezifileyo.

Ngaphambili bekucingelwa ukuba iiseli zemithambo-luvo musa ukuntshula. Noko ke, le yinto leyo, wawancamisa ekuhleni ngamayeza mihla. Nangona kungekho ukukwazi ukwahlula, iiseli zemithambo-luvo ukuba ukuntshula nokuphuhlisa ebuchotsheni, nkqu nomntu omdala. Ukongeza, luvo nga ubunokuzihlaziya waso ezilahlekileyo nokunxibelelana nabanye iiseli.

Iqela Okubaluleke kakhulu iiseli zemithambo akhiwe ebuchotsheni. Ngenxa off-amasebe kwakheka abafowunelwa amaninzi kunye luvo angabamelwane.

Cranial, spinal kunye yawo iindawo, luvo kwalapho kunye luvo, ukubonelela Uhanjiso neemvakalelo ukuya izihlunu, izibilini omzimba, inxalenye neuropathy zenza luvo yabantu.

Inkqubo luvo emzimbeni nempilo inkqubo kakuhle. Nakuba kunjalo, ukuba kwikhonkco entsonkothileyo omnye amakhonkco akusekho azalisekise imisebenzi yawo, ukuze babe ukubandezeleka umzimba uphela. ukwenzakala kwengqondo ezimandundu eziyelelene izifo, ukufa kwamalungu omzimba, Parkinson xa isifo i-Alzheimer kukhokelela kwilahleko olukhawulezileyo zemithambo-luvo. Amashumi eminyaka, izazinzulu bazama ukuphendula umbuzo njani iiseli zemithambo-luvo ukuvuselela.

Namhlanje kwakusazeka ukuba isizukulwana zemithambo-luvo kwi abadala ebuchotsheni mammalian enokwenziwa usebenzisa iiseli Isiqu ezizodwa (ebizwa ngokuba yi-neuronal). Ngeli xesha bafumanisa ukuba iiseli zemithambo-luvo zifunyanwe kwindawo subventricular, Hippocampus (dentate gyrus), kunye uthinte cerebellar. Icandelo lokugqibela amakishe neurogenesis kakhulu. KwiCerebellum libandakanyeka ekufumaneni nokugcina ulwazi malunga izakhono ngokuziphatha zingqondweni. Umzekelo, intshukumo razuchivaya umdaniso, abantu ngokuthe ngcembe uyayeka ukuba bacinge ngazo, wenza ngokuzenzekelayo.

Oosonzululwazi zibangel bakholelwa nokuhlaziya ngokutsa luvo kwi gyrus dentate. Kulo mmandla, ukuzalwa iimvakalelo, ukugcina nokuhoywa ngolwazi lwesithuba. Izazinzulu ziye kodwa wakwazi ukuphelisa ukuqonda indlela luvo elisandul 'ukusekwa kuchaphazela iinkumbulo sele kwakhiwa, yaye njani intsebenziswano zabo luvo abaqolileyo kulo mmandla ebuchotsheni.

Izazinzulu qaphela ukuba iiseli zemithambo-luvo zibuyiselwa kwezo ndawo, athi abenoxanduva ngqo ukusinda kwi-moya ngokwasemzimbeni: kuqhelaniswa isithuba, ivumba, ukuyilwa motor memory. Formation of nekhono lokuhlaziya iya esebenzayo eselula, ngexesha ukukhula kwengqondo. Kule neurogenesis lu dityanisiwe yonke imimandla. Emva kokuba uphuhliso ebudaleni kwemisebenzi cognitive ikhutshwa phandle hlengiso nabo phakathi luvo, kodwa ngenxa ukuyilwa iiseli ezintsha.

Kufuneka kuqatshelwe ukuba izazinzulu kuqhubeka ukukhangela nakujoliso olutsha ngaphambili olungaziwayo lwe neurogenesis, nangona abaliqela kwempumelelo. Le indlela ubaluleke nje kuphela inzululwazi esisiseko kodwa uphando kwakhona izicelo.
