March 2024: Ukwelashwa kwe-stem cell kuye kwavela njengendlela yokwelapha ethembisayo yesifo sikashukela, okungenzeka kubhekwane nezithiyo iziguli ezihlangabezana nazo. Ucwaningo kulo mkhakha luphenye izinhlobo ezahlukahlukene zamaseli e-stem, njengamaseli e-embryonic stem cell, ama-stem cell enziwe i-pluripotent, amaseli we-umbilical cord stem, namaseli e-mesenchymal atholakala kumnkantsha, njengezinye izindlela zamaseli e-embryonic stem ukubhekana nokulinganiselwa kwawo.
Intuthuko Ocwaningweni Lwe-Stem Cell
Ucwaningo lwakamuva lubonise impumelelo enkulu ekusebenziseni ama-stem cells ukuze kuhlukaniseke ama-β cell kanye nokuvuselelwa kabusha kwe-pancreatic, okuyizinto ezibalulekile ekuxazululeni izinkinga eziwumsuka zesifo sikashukela. Isiqu ukwelashwa kwamaseli ifuna ukwakha amangqamuzana akhiqiza i-insulini akwazi ukuphendula kahle emazingeni eglucose, anamandla okubuyisela emuva izimpawu zesifo sikashukela ngokuvuselelwa kabusha kwama-pancreas. Amaseli esiqu e-pluripotent womuntu angasetshenziswa ukwenza ama-β-cell avuthiwe, asebenzayo, kodwa izinkinga ezinjengokuvikela amaseli akhiqiza i-insulin afakiwe ezimpendulweni ze-autoimmune zisasetshenzwa.
I-Latin America's Call to Action
I-Latin America ikuvumile ukubaluleka kocwaningo lwe-stem cell ekwelapheni umthwalo wesifo sikashukela esifundeni. Imizamo iyenziwa yokukhuthaza ucwaningo olusha kanye nokubeka izinqubomgomo zokusiza ekuthuthukisweni kokwelashwa kwe-stem cell ekwelapheni isifo sikashukela. Ukugcizelela kwesifunda ekuthuthukiseni amaseli akhiqiza i-insulin asabela ku-glucose kanye nokuphenya amaseli e-mesenchymal stem njengamathemba okwelapha kubonisa intshisekelo ekhulayo yokusebenzisa amasu asekelwe ku-stem ukwelapha izinkinga zesifo sikashukela.
Amathemba Nezinselele Zesikhathi esizayo
Nakuba ukwelashwa kwe-stem cell kubonisa isithembiso sokwelapha isifo sikashukela sohlobo loku-1, kusenezinselelo zobuchwepheshe okufanele zinqobe. Izinkinga ezinjengokukhiqiza izinhlobo zamaseli eziqondiwe ezanele zokufakelwa kabusha, ukuqinisekisa ukuzimela okuphelele kwe-insulin, kanye nokunqoba imikhawulo isivivinyo somtholampilo imiphumela ihlinzeka ngezithiyo ezidinga ukutadisha nokuthuthukiswa okwengeziwe. Amasu e-encapsulation aye aphenywa ukuze kuvikelwe amangqamuzana atshalwe kabusha ekuphenduleni amasosha omzimba, okusikisela indlela engaba khona yokuthuthukisa ukusebenza kahle kwe-stem cell therapy yesifo sikashukela.
Okokugcina, i-stem cell therapy inamandla okuguqula ukwelashwa kwesifo sikashukela. Izindlela zokwelapha ezisekelwe ku-stem cell ezinikeza ithemba ezigulini emhlabeni wonke zinganquma ikusasa lokwelashwa kwesifo sikashukela ngocwaningo oluqhubekayo kanye nentuthuko yezobuchwepheshe.
