Kutsogola Kwamapulogalamu a Stem Cell

M'zaka zaposachedwa, kupita patsogolo kwakukulu kwachitika pakugwiritsa ntchito ma cell stem padziko lonse lapansi. Kafukufuku wambiri woyesera awonetsa kuthekera kwa maselo oyambira pochiza matenda osiyanasiyana, kuwonetsa kusinthasintha kwawo pothana ndi zovuta zachipatala. Nazi zitsanzo zodziwika:

(1) Ma Embryonic Stem Cell for Heart Tissue Generation:

Israel Institute of Technology yachita bwino kwambiri pokulitsa minofu ya mtima wamunthu kuchokera ku maselo a embryonic stem cell. Kukula kwakukulu kumeneku kumaphatikizapo kulima minofu ya mtima ndi mphamvu zakugunda kwachilengedwe, zomwe zimakhala ndi electrophysiological komanso makina monga minofu yamtima yobadwa kumene. Izi zili ndi lonjezo lalikulu lochiza matenda a mtima.

(2) Ma cell a Hematopoietic Stem Cells ndi Impso Tissue:

Asayansi a ku Britain anena za kupambana kwakukulu kwa opaleshoni yoika ziwalo mwakukula bwino minofu ya impso kuchokera ku maselo a m'mafupa. Kupita patsogolo kumeneku kumatanthauza kusintha kwa kusintha kwa ziwalo, kuchotsa kudalira zopereka za ziwalo. Kuphatikiza apo, kafukufukuyu akuwonetsa kuti maselo akuluakulu am'mafupa amatha kukhwima kukhala maselo a impso ogwira ntchito, kupereka njira zatsopano zochizira komanso kukonza impso zomwe zawonongeka.

(3) Maselo a Neural Stem mu Chithandizo cha Matenda a Parkinson:

Katswiri wa sayansi ya ubongo wa ku Sweden a Biorklund ndi othandizana nawo agwiritsa ntchito maselo a neural stem olekanitsidwa ndi ana obadwa kumene kuti athe kuchiza matenda a Parkinson. Kafukufuku wotsatira awonetsa kuti ma neuron omwe adasinthidwa amakhalabe otheka, akupitiliza kupanga dopamine, zomwe zimapangitsa kusintha kwakukulu kwazizindikiro za odwala. Ntchitoyi ikuwonetsa kuthekera kwa ma cell a neural stem mumankhwala ochizira matenda amisala.

(4) Ma cell a Pancreatic Stem for Diabetes:

Pulofesa Ramiya ndi ogwira nawo ntchito ku yunivesite ya Florida apatula ma cell a pancreatic stem kuchokera ku ma islet ducts a mbewa omwe ali ndi matenda ashuga. Kudzera mu in vitro induction, ma cellwa adasiyanitsidwa kukhala ma cell a beta omwe amapanga insulin. Kuyesa kwapathupi kunawonetsa kuti mbewa za odwala matenda ashuga omwe amawaika awa amawongolera shuga wawo m'magazi, ndikupereka njira yabwino yochizira matenda a shuga. Kafukufukuyu akuwonetsa gawo lofunikira popanga njira zatsopano zochizira matenda a shuga.

Kupita patsogolo kumeneku kumatsimikizira kusintha kwa kafukufuku wa stem cell pakukonzanso malo a chithandizo chamankhwala, kupereka chiyembekezo cha njira zogwira mtima komanso zogwirizana kuti athe kuthana ndi matenda osiyanasiyana.
