Umbilical Stem Cells Popkov izvornih celic

Advances In Stem Cell Parkinson's Predplačila V Stem Cell Parkinsonovo

Much effort and time had been given to research of stem cells to repair damaged human tissue. Veliko truda in časa je bila dana za raziskave izvornih celic za popravilo poškodovanih človeških tkiv. One area that has been studied is Stem Cell Parkinson's . Eno od področij, ki je bil raziskan, je Stem Cell Parkinsonove. 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. Nekdo, ki trpi za parkinsonovo boleznijo kaže simptome, kot so težave pri gibanju, ravnotežju in govoru zaradi smrti možganskimi celicami, ki proizvajajo snovi imenujemo dopamin.

Dopamine, obviously, helps regulate movement, balance and speech. Dopamin, seveda, pomaga urejati gibanja, ravnotežje in govora. 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. Torej je cilj te raziskave je bil, da bi nadomestil mrtve celice z novimi, zdravimi zarodnimi celicami, ki se lahko sproži, da postanejo celice, ki proizvajajo dopamin v možganih. Although this seems straight forward, there are hurdles to collection and replacement of these special cells. Čeprav se to zdi naravnost naprej obstajajo ovire za zbiranje in zamenjavo teh posebnih celic.

Stem cells come in a variety of stages and are the basic building block of every tissue in the body. Izvornih celic nadaljuje na različnih stopnjah ter so temeljni element vsakega tkiva v telesu. Stem cells are waiting for triggers to help them decide what part of the body they will become. Zarodnih celic, so čakali na sprožilce, da bi jim pomagali odločiti, kateri del telesa bodo postali. This is why they have been studied for Stem Cell Parkinson's treatments. To je razlog, zakaj so bili raziskani v steblo ječa samica zdravljenje Parkinsonove.

The 'youngest' stem cells are called early embryonic stem cells. The "najmlajši" matične celice, se imenujejo zgodnjih embrionalnih matičnih celic. These cells are formed in the first six days of life, following the fertilization of an egg. Te celice so nastale v prvih šestih dneh življenja, po oploditev jajce. They are termed totipotent, which means they have the ability to become any cell type or kind in the body. Ti se imenujejo totipotentnih, kar pomeni, da imajo možnost, da postanejo kakršne koli vrste ali vrste celic v telesu.

At day seven, following fertilization, the cells are referred to as blastocyst embryonic stem cells or late embryonic stem cells. Na sedem dni po oploditvi, celice so označene kot blastocyst embrionalnih zarodnih celic ali pozno embrionalnih matičnih celic. Now they have the ability to become most every cell in the body, although they do have a few limitations. Zdaj imajo možnost, da postane najbolj vsake celice v telesu, čeprav imajo nekaj omejitev. They are considered pluripotent and they still have no features of a human body. Te so pluripotentne in so še vedno nima značilnosti človeškega telesa.

As the development continues, at week eight the cells are referred to as fetal stem cells. Ker je razvoj nadaljeval, na osem tednov se celice označene kot zaroden matičnih celic. They are still considered pluripotent, but have began the initial development of tissue that now resembles a human body. So še vedno šteje za pluripotentne, vendar so se začeli začetnega razvoja tkiv, ki zdaj spominja na človeško telo. Pluripotent stem cells are the most useful Stem Cell Parkinson's for treatment. Pluripotentnimi zarodnimi celicami so najbolj koristne zarodnih celic za zdravljenje Parkinsonove.

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. Ker so embrionalne matične celice v možganih, še posebej pri plodu fazi, so bili sproženi postanejo celice, ki proizvajajo dopamin, bodo najboljša izbira za Stem Cell Parkinsonove. But obtaining these cells is a large hurdle for some. Toda pridobitev teh celic je velika ovira za nekatere. They can be taken from early termination of a pregnancy, either intentional or non-intentional. Lahko se vzamejo iz zgodnje prekinitve nosečnosti, bodisi namerne ali nenamerne namerna.

Once the cells have been harvested, they then must be implanted into the brain of the recipient. Ko se celice so bili pridelani, ki jih potem mora biti vsadi v možgane o prejemniku. And then they have to be triggered to produce dopamine by the recipients body. In potem jih je treba sprožiti, da proizvajajo dopamin, ki jih prejemniki telo. Some transplantation has been successful in that the patient has noticed a decrease in the difficulty with walking, balance and speech. Nekatere transplantaciji je bila uspešna v tem, da bolnik je opaziti zmanjšanje težave s hojo, ravnotežje in govora.

There have also been some side effects of this treatment to include additional muscle twitching and jerking. Tu so bili tudi nekateri neželeni učinki tega zdravljenja, da vključujejo dodatne mišice twitching in jerking. Great strides have been made in this area, with much room for improvement remaining. Zelo so bila na tem področju, z veliko prostora za izboljšave preostali.
