Sık sık bir AAO imalatı kusurları çatlaklar, gözenekleri ve yazma düzensiz şekiller gibi muzdarip. Ana nedeni bu kusurları için güçlü Eloksal metal yüzeylerde yapısı ve elektrolit21direnci etkilenir elektrolitik bir arıza denir. Bağlı olarak sıcaklık elektrolit direnci değişir bu yana ısı sürekli elektrotlar ortadan kaldırmak olarak böyle bir yüksek gerilim Eloksal durum ahırda elektrolit gerektirebileceği sıcaklığı korumak için kritik nokta olduğunu. Bu ileti?...

Yanıt hücre yüzey topografyası fiziksel uyarılması tarafından son zamanlarda, hücre mühendislik1,2,3,4alanında kataloglarımızda. Bu nedenle, daha fazla dikkat hücre ek yüzey5üç boyutlu nanoyapıların üzerinde duruldu. Bu hücre yüzey tanıma oyunlarından biri, integrin ECM mikro-nano yapılar ile mekanik iletim6tarafından tahrik fiziksel uyarıcı iletir bildirilmiştir. Bu mekanik stimülasyon hücre davranış ile ilgili rehberlik7 düzenleyen ve odak yapışıklıklar ve sertlik hücre8' in yanı sıra şeklini değiştirmek için hücre iskeleti yeniden yapılanma neden olmaktadır.
İnsan endotelyal progenitor hücreler (hEPCs) vücuttaki yakından çevreleyen ECM9microenvironment ile etkileşim. Bu kesme stres kan akışı10' dan türetilmiş kadar ECM fiziksel durumunu belirli hücre-matris yapışması karmaşık oluşumu için önemli bir parametre olarak davranır gösterir. Bu yüzey nanotopography geniş kılcal tüp ağlar hEPCs11 ' in vitro oluşumunu artırır ve ECM/biyo çözünür faktör sistem kombine hEPCs işlevsel olmayan yüzeylerde tanımasını sağlar ve destekler bildirilmektedir şifa12,13yara. Yine de, ECM ve hEPCs arasındaki ilişkiyi açıkça anlaşılmış değildir.
Hücre yanıtları ve fiziksel ipuçları farklı yüzeylerde14,15,16arasındaki ilişkiyi açıklamak için pek çok araştırmacı çalıştı rağmen bu çalışmalar bir nanostructure yalnızca sabit boyutu kullanılan veya nanopatterns nanostructure ve hücre davranışını boyutu arasındaki ilişkiyi aydınlatmak için bir sınırlama var düzensiz düzenlemeler ile. Buradaki sorun nanostructure en uygun boyutu bulmak için varolan sıkıcı ve yinelemeli yaklaşımlar yerine hücresel yanıt süzmek için uygun araçlar eksikliğidir. Bu nedenle, basit bir teknik tekrarlama olmadan fiziksel elektrodlar hücre reaksiyonlar eleme için gereklidir.
Burada, bizim önceki raporlar17,18,19 içinde hangi görücü usulü nanopillars çapını yavaş yavaş artar bir degrade nanopattern üretmek için kullanılan bir yöntem açıklanmaktadır. Buna ek olarak, ayrıca nasıl yetiştirmek ve hECFCs fiziksel bir çekim gücü etkisi hücreleri belirlemek için degrade nanopattern plakaları davranışını analiz nitelendirdi. Hafif anodization, yavaş yavaş gravür ve anti-yapışma katman kaplama yöntemi degrade AAO kalıp imal etmek kullanılmıştır. Litografi tekniği basma bir termal benimseyerek, aynı polistren degrade nanopatterns bir maliyet-etkin ve facile şekilde üretilmiştir. Degrade nanopatterns kullanarak, hangi boyutunu nanostructure deney bir dizi hücre davranışı üzerinde büyük bir etkiye sahip belirlemek için mümkün olabilir. Biz bu gradyan nanopattern kan kaynaklı hECFC veya diğer hücreler ve taşınımı çeşitli boyutlarda arasındaki etkileşim mekanizmaları anlamada yardımcı olacaktır bekliyoruz.

fabrication of gradient nanopattern by thermal nanoimprinting technique and screening of the response of human endothelial colony-forming cells

Nanotopography çeşitli hücre dışı matrisler (ECMs) vücut etrafında bulunabilir ve hücresel reaksiyonlar üzerine önemli yasal eylemleri sahip olduğu bilinmektedir. Ancak, bir nanostructure boyutunu ve hücre uygun tarama araçları eksikliği nedeniyle yanıt arasındaki ilişkiyi belirlemek zordur. İşte, tekrarlanabilir ve düşük maliyetli degrade nanopattern plakaları hücresel yanıt manipülasyon gelişimini göstermektedir. Ana kalıp, degrade nanopattern pilakalar ve artan çap aralığı [120-200 nm (GP 120/200), 200-280 nm (GP 200/280) ve 280-360 nm (GP 280/360)] nanopillars olarak anodik alüminyum oksit (AAO) kullanarak basma tekniği bir termal tarafından fabrikasyon. Bu degrade nanopattern plakaları nanotopography ECM içinde çeşitli boyutlarda taklit etmek için tasarlanmıştır ve insan endotel koloni oluşturan hücre (hECFCs) yanıt-e doğru elemek için kullanılmıştır. Bu protokol için mühendislik, hECFCs insan periferik kandan yetiştirilmesi ve hECFCs nanopattern plakaları kültür teknikleri hücre için degrade nanopattern tabak imalatı, adım adım bir yordam açıklanmaktadır.

Şekil 1 SEM görüntüleri uydurma degrade AAO kalıp türüne ve konumuna göre gösterir. Şekil 2 SEM görüntüleri degrade nanopattern plakaları ile normal yuvarlak nanopillars gösterir ve Şekil 3 nanopillar çapının miktar verilerdir. Tablo 1 fabrikasyon nanopillars özellikleri listeler.
