İşte biz o tek hücre RNA seq ile her hücreyi çalışma, bir floresan etiketi kullanarak heterojen bir nüfus tek hücreleri izole. Biz hasat edilmiş ve dizilenmiştir canlı TH EGFP hücrelerinin% 100 aşağıdaki üç DA-ilişkili gen transkriptleri, Th, DDC ve slc6a3 varlığına dayanarak, gerçekten de dopaminerjik nöronların olduğunu rapor etmektedir. RNA Sek tarafından değerlendirilen TH-eGFP pozitif hücrelerin bu üç gen ifade etti. Bu, her bir TH-eGFP hücresi dopaminerjik nöronlar <sup class="xref...

Parkinson Hastalığı (PH) çaresiz bir, yaşa bağlı nörodejeneratif bir hastalıktır. Bu nispeten yaygın hastalığın nedeni tam olarak anlaşılamamıştır kalır. bradikinezi, katılık ve titreme tanısal klinik özelliklerine lider Substansiya Nigra (SNC) dopaminerjik nöronların belirgin nöron dejenerasyonu ile beynin genelinde yaygın nöron kaybı, vardır. SNc dopaminerjik nöron içeren primer karma kültürler Parkinson hastalığı için, özellikle önemlidir. Ventral Tegmental Alanı (VTA) dopaminerjik nöronların ödül ve bağımlılık sorumlu tutulmuştur. Ventral Mesensefalik (VM) primer karma embriyonik kültürleri SNc ve VTA dopaminerjik (DA) nöronlar ve GABAerjik nöronlar ikisini de içerir. VM birincil kültürleri nöroprotektif tahlilleri için yararlı olabilir ve dopaminerjik nöronların seçici güvenlik aydınlatmak için. morfolojisi dayalı kültür dopaminerjik hücrelerin belirlemek için güvenilir bir yolu yoktur. obiz tek hücreli, yüksek verim RNA sıralama kütüphaneleri belirlemek ve tek dopaminerjik nöronların hasat ve inşa teknikleri geliştirmek yeniden. Biz tek dopaminerjik ve orta beyin kültürlerinden izole edilen GABAerjik nöronlar için temsili RNA transcriptome rapor verilerini. Bu protokol, DA / GABA transcriptome çeşitli tedavilerin etkisini incelemek için nöro-koruma, nörodejenerasyon, ve farmakolojik tahliller için de kullanılabilir. dopaminerjik nöronlar primer VM kültürlerinde ifade nöronların küçük bir azınlığı temsil ettikleri için, güvenilir yaşayan kültürlerde bu nöronlar tanımlamak için yeteneği tek hücreli çalışmalarının gelişmiş bir dizi sağlayacaktır. Bu yeni teknikler hücresel düzeyde gerçekleşen mekanizmaların anlaşılması gelişmeler kolaylaştıracak ve başka bir yerde nörobilim ve moleküler biyoloji alanlarında uygulamalar olabilir.

reliable identification of living dopaminergic neurons in midbrain cultures using rna sequencing and th-promoter-driven egfp expression

<html> Parkinson Hastalığı (PH) bradikinezi, katılık ve titreme neden, Snc dopaminerjik nöronların belirgin dejenerasyon ile beynin genelinde yaygın nöronal kaybı vardır. floresan işaretleyici kullanarak birincil Ventral Mesensefalik (VM) kültürlerde yaşayan dopaminerjik nöronların belirlenmesi sabit hücrelerin immün dayanmadan bu nöronların seçici açığı incelemek için alternatif bir yol sağlar. Burada, izole, ayrışır ve kültür fare VM nöronlar 3 hafta boyunca. Daha sonra (bir tirosin hidroksilaz (TH) promoteri tarafından tahrik edilen) EGFP floresan kullanılarak kültürler dopaminerjik nöronların tanımlar. Bireysel nöronlar cam mikropipetler kullanarak mikrosantrifüj tüpler içine hasat edilir. Sonra, hasat edilen hücreler lize ve tek bir hücre RNA Seq kitaplıkları da 1, 2 üretmek için cDNA sentezi ve transpozon aracılı &quot;tagmentation&quot; yapmak,eşek = &quot;xref&quot;&gt; 3, 4, 5. Bir kalite kontrol kontrolünü geçtikten sonra tek hücreli kütüphaneleri sekanslanır ve sonraki analiz gen ekspresyonunu ölçmek için gerçekleştirilir. Biz bireysel dopaminerjik ve orta beyin kültürlerinden izole edilen GABAerjik nöronlar için transcriptome sonuçlarını rapor. Bu hasat edilmiştir ve dizilenmiştir canlı TH EGFP hücrelerinin% 100 dopaminerjik nöronların olduğunu rapor etmektedir. Bu teknikler nörobilim ve moleküler biyoloji yaygın uygulamalara sahip olacaktır.

Burada, bir tirosin hidroksilaz promotör sekansı ile tahrik eGFP eksprese eden bir fare ön orta beyin nöronları kültür kültürlerden bağımsız flüoresan nöronlar hasat ve RNA SEQ (Şekil 1) kullanılarak, RNA transcriptome ölçmek için bir protokolü sunulmaktadır. veriler toplandı ve dizilenmiştir TH-EGFP-pozitif hücre% 100 aşağıdaki üç DA-ilişkili gen kopyalarının varlığı, Th, dopa dekarboksilaz (DDC), ve dopamin transportörü DAT göre, d...
