Kanıt büyüyen kök hücre vaadi bir roman kontur terapi olarak göstermiştir. Bu söz kök hücre therapeutics yatağımın en az 40 tamamlanmış veya devam eden klinik çalışmalar ile ilerlemek için önemli bir çalışma sonuçlandı. Kontur patoloji çünkü akut hakaret sonra kurtarma engelleyen hiçbir nörodejeneratif işlem ödünç vermek kendisi için kök hücre tedavisi benzersiz bir nörolojik bozukluk sunmaktadır. Kök hücre gelişmiş inme kurtarma tam mekanizmasının belirsizdir. Anjiogenez, syn...

İnme dünyada ölüm ikinci önde gelen nedenidir ve ölüm beşinci önde gelen nedenidir Amerika Birleşik Devletleri olduğunu. Bu yüksek ölüm oranlarını rağmen tedaviler inme kurtarma için şu anda bir sorun yok uygun tıbbi seçenekler mevcut1kalır. Orada şu anda yaklaşık 300 klinik çalışmalarda hangi kök hücreler sadece 40 kullanmak iskemik inme ile ilgili. Önceki çalışmalarda kök hücre tedavileri kontur onarım2,3üzerinde yararlı bir etkisi olduğunu ortaya koymuştur. Parakrin faktörler beyin kaynaklı Nörotrofik faktör (BDNF) ve Transplante insan nöral progenitör hücre (hNPCs) yayımlanan trombospondin-1 (THBS-1) gibi bir artış ile ilgili mekanizmalar yoluyla geliştirilmiş fonksiyonel iyileşme göstermiştir oluşumu, anjiogenez, dendritik dallanma ve yeni aksonal projeksiyonlar sinaps gibi bağışıklık sistemi4,5,6modülasyonlu. Ancak, kök hücrelerin en uygun teslimat yöntemlerinin zor kalır.
Başarılı kök hücre teslim beyin için bir meydan okuma olarak kalır. Şu anda, enjekte edilebilir hidrojel ve polimerik İskele sistemleri kök hücre sunmak için getirilmiştir. Bu teslim yöntemi kök hücre nakli sırasında korumak hem de ana bilgisayarın inflamatuar yanıt ve hipoksik koşullar7,8,9 gibi sert inme sonrası çevre koruma , 10. ancak, en yaygın olarak kullanılan malzemeler hangi hücreleri11sürekli Modülasyon (Yani, elektriksel stimülasyon) kısıtlar etkisiz,. Elektriksel stimülasyon farklılaşma, iyon kanal yoğunluğu ve kök hücre12neurite akıbet etkiler bir ipucudur. İnert polimerler ile karşılaştırıldığında, elektriksel stimülasyon ve kök hücre2manipülasyon için geçerli bir izin iletken polimerler taşıyabilir. Ancak, hangi tarafından Nörotrofik faktör sürümü (Yani, BDNF ve THBS-1) elektriksel stimülasyon modüle kesin mekanizması hala tam keşfedilmeden.
Bu protokol için bir iletken polimer iskele, vitro için elektriksel stimülasyon sağlar polypyrrole (PPy), oluşan bir hücre kültür sistemi oluşturmak için adımları açıklar. Hangi hücre kültür sistemi fabrikasyon olduğunu şekilde nedeniyle, peri-enfarktüsü korteks üzerine kök hücre numaralı seribaşı iskele sonraki implantasyonu mümkündür. Bu sistem için biz elektrikle kök hücre iskele üzerinde kısa bir süre önce implantasyon için yaygõn. Elektriksel stimülasyon hücreleri taşıyan iletken polimer iskele intracranially minimal invaziv bir yöntem kullanarak başarılı bir şekilde yerleştirilir.

electrically conductive scaffold to modulate and deliver stem cells

Kök hücre tedavisi heyecan verici bir kontur olarak terapötik çıkmıştır ama en uygun Teslimat yöntemi belirsizdir. Mikroenjeksiyon tekniği kök hücre kontur modellerinde sunmak için yıllardır kullanılan iken, bu teknik enjeksiyon önce kök hücre işleme yeteneği eksikliği ile sınırlıdır. Bu kağıt bir elektriksel olarak iletken polimer iskele kök hücre teslim için kullanma yöntemi ayrıntıları. Bir iletken polimer iskele kullanarak kök hücrelerin elektriksel stimülasyon kök hücrenin genler hücre hayatta kalma, inflamatuar yanıt ve sinaptik remodeling yer değiştirir. Elektrik Önkoşullanma sonra iskele üzerinde kök hücre intracranially distal orta serebral arter tıkanıklığı sıçan modelinde nakledilen. Bu iletişim kuralı bir iletken polimer iskele üzerinden kök hücre işlemek için güçlü bir teknik anlatılmaktadır ve daha fazla kök hücre tabanlı terapisi geliştirmek için yeni bir araç oluşturur.

Şekil 1 ' de gösterilen şematik genel iş akışını hNPCs ve potansiyel aşağı akım uygulamaları elektriksel stimülasyon ve temsil eder. Bir geçerli kök hücre tedavisi, kök hücre iltihabı ve iskemik koşulları gibi sert bir sonrası nakli ortamına maruz kısıtlamadır. Bu zor koşullar büyük olasılıkla onların tedavi edici etkinliği14,15sınırlayın. Bu ortamdan hNPCs korumak...
