Advances In Stem Cell Parkinson's Avvanzi Fil Stem Cell Parkinson

Much effort and time had been given to research of stem cells to repair damaged human tissue. Ħafna isforz u l-ħin kienu ġew mogħtija għar-riċerka ta 'ċelloli staminali biex tiswija danneġġata-tessut uman. One area that has been studied is Stem Cell Parkinson's . Qasam wieħed li ġie studjat huwa Stem Cell Parkinson. Someone that suffers from Parkinson's disease displays symptoms such as difficulty with movement, balance and speech due to the death of brain cells that produce a substance called dopamine. Xi ħadd li ssofri mill-marda Parkinson displays sintomi bħal diffikultà mal-moviment, u diskors bilanċ minħabba l-mewt ta 'ċelluli li jipproduċu brain sustanza msejħa dopamine.

Dopamine, obviously, helps regulate movement, balance and speech. Dopamine, ovvjament, jgħin jirregolaw moviment, il-bilanċ u diskors. So the goal of this research was to replace the dead cells with new, healthy stem cells that can be triggered to become dopamine producing cells in the brain. Allura l-għan ta 'din ir-riċerka kien biex tissostitwixxi l-ċelluli mejta mal ġodda, b'saħħithom ċelloli staminali li jista' jiġi attivat biex issir ċelloli li jipproduċu dopamine fil-moħħ. Although this seems straight forward, there are hurdles to collection and replacement of these special cells. Għalkemm dan jidher straight forward, hemm ostakli għall-ġbir u s-sostituzzjoni ta 'dawn iċ-ċelluli speċjali.

Stem cells come in a variety of stages and are the basic building block of every tissue in the body. Ċelloli staminali jidħlu f'varjetà ta 'stadji u huma l-element bażiku ta' kull tessut fil-ġisem. Stem cells are waiting for triggers to help them decide what part of the body they will become. Ċelloli staminali attendent jqajjem biex jgħinuhom jiddeċiedu liema parti tal-ġisem huma ser isiru. This is why they have been studied for Stem Cell Parkinson's treatments. Dan huwa għaliex dawn ikunu ġew studjati għal Stem Cell Parkinson trattamenti.

The 'youngest' stem cells are called early embryonic stem cells. Il-"Liżgħar 'ċelloli staminali huma msejħa kmieni ċelluli stem embrijoniċi. These cells are formed in the first six days of life, following the fertilization of an egg. Dawn iċ-ċelluli huma ffurmati fl-ewwel sitt ijiem tal-ħajja, wara l-fertilizzazzjoni tal-bajda. They are termed totipotent, which means they have the ability to become any cell type or kind in the body. Huma msejħa totipotent, li jfisser li jkollhom l-abbiltà li jsir kull tip jew tip ta 'ċellula fil-ġisem.

At day seven, following fertilization, the cells are referred to as blastocyst embryonic stem cells or late embryonic stem cells. Fl seba 'jum, wara fertilizzazzjoni, iċ-ċelloli huma msemmija bħala blastoċeste ċelluli stem embrijoniċi jew tard ċelluli stem embrijoniċi. Now they have the ability to become most every cell in the body, although they do have a few limitations. Issa għandhom il-kapaċità biex isir aktar minn darba kull ċellula fil-ġisem, għalkemm dawn ikollhom ftit limitazzjonijiet. They are considered pluripotent and they still have no features of a human body. Huma kkunsidrati pluripotenti u dawn ikunu għadhom ebda fatturi ta 'ġisem uman.

As the development continues, at week eight the cells are referred to as fetal stem cells. Billi l-iżvilupp tkompli, f'ġimgħa tmien-ċelloli huma msemmija bħala fetali ċelloli staminali. They are still considered pluripotent, but have began the initial development of tissue that now resembles a human body. Huma għadhom meqjusa pluripotenti, iżda beda l-iżvilupp inizjali ta 'tessut li issa tixbah ġisem uman. Pluripotent stem cells are the most useful Stem Cell Parkinson's for treatment. Ċelluli staminali pluripotenti huma l-aktar utli Stem Cell Parkinson għat-trattament.

Because the embryonic stem cells in the brain, especially in the fetal stage, have been triggered to become dopamine producing cells, they make the best choice for Stem Cell Parkinson's. Minħabba li l-ċelluli staminali embrijoniċi fil-moħħ, speċjalment fil-fetali istadju, jkunu ġew attivati sabiex isiru ċelloli li jipproduċu dopamine, li jagħmlu l-aħjar għażla għall Stem Cell Parkinson. But obtaining these cells is a large hurdle for some. Iżda jikseb dawn iċ-ċelluli hija ostaklu kbir għal xi wħud. They can be taken from early termination of a pregnancy, either intentional or non-intentional. Huma jistgħu jittieħdu mill-terminazzjoni bikrija ta 'tqala, jew intenzjonali jew mhux intenzjonali.

Once the cells have been harvested, they then must be implanted into the brain of the recipient. Ladarba l-ċelluli ġew maħsuda, dawn imbagħad għandhom ikunu impjantati fil-moħħ tar-riċevitur. And then they have to be triggered to produce dopamine by the recipients body. U mbagħad dawn għandhom ikunu attivati sabiex jipproduċu dopamine mir-riċevituri korp. Some transplantation has been successful in that the patient has noticed a decrease in the difficulty with walking, balance and speech. Xi trapjant irnexxa fir-rigward li l-pazjent irid nnutat tnaqqis fil-diffikultà bil-mixi, il-bilanċ u diskors.

There have also been some side effects of this treatment to include additional muscle twitching and jerking. Kien hemm ukoll xi effetti sekondarji ta 'dan it-trattament biex tinkludi addizzjonali muskoli twitching u jerking. Great strides have been made in this area, with much room for improvement remaining. Kbir bil saru f'dan il-qasam, ħafna lok għal titjib fadal.
