Hücre dışı veziküller (EVs) tümör salgılanan tümör destekleyici bir ortam oluşturmak için yerel ve uzak Mezenkimal hücreler fizyolojisi değiştirebilirsiniz. Burada diseksiyon tümör hücreleri arasında EV-aracılı etkileşimlerin sağlar osteosarkom preklinik fare modeli nesil tanımlamak ve (MSCs) vivoMezenkimal Kök hücreler. Biz insan tümör EV eğitimli MSCs osteosarkom xenografts şiddetle taşıyan farelerde sistemik enjeksiyon IL-6/STAT3 sinyal yolu7aktive edere...

Tümör microenvironment metastaz oluşumu ve tedavi1direnç gelişimi de dahil olmak üzere tumorigenesis ve kanser progresyon çoğu, hepsi değilse de, özelliği aktif olarak katılmaktadır. Bu diseksiyon tümör niş içinde meydana gelen karmaşık tümör-stroma etkileşimlerin izin preklinik orthotopic kanser fare modelleri gerekliliğini vurguluyor.
Tümör microenvironment birçok hücresel bileşenleri arasında Mezenkimal Kök hücre (MSCs) kuvvetle kanser meme kanseri, prostat kanseri, Beyin tümörleri, Multipl Miyelom ve osteosarkom2 gibi birden çok kanser türü ilerlemesinde katkıda ,3,4,5,6,7. MSCs kemik iliği, yağ dokusu, plasenta, göbek kordon kanı ve diğerleri de dahil olmak üzere çeşitli yetişkin ve fetal dokularda,8,9bulunan multipotent kök hücreler vardır. İnflamatuar sinyaller kanser üretilen cevaben, MSCs tümör siteleri doğru geçiş, tümör microenvironment dahil etmek ve sonuçta kanser destek hücreleri10ayırt etmek. Bu kanser ilişkili MSCs temel faktörler (Yani, büyüme faktörleri, kemokinler, sitokinler ve immünsupresif arabulucu) tümör hücreleri hem de çevresindeki stroma2, hareket tümör ilerleme sağlamak 3 , 11 , 12 , 13. kanser ilişkili MSCs tümör teşvik etkileri çok sayıda kanser modellerinde araştırdık iken, hangi tarafından tümör hücreleri yeniden programlamak kanser teşvik niş şekillendirmek için MSCs mekanizmalar kötü anlaşılır. Burada özellikle kemik kanseri hücreleri ve MSCs pro tumorigenic etkileşimini ekstraselüler veziküller (EVs) yolu ile çalışma sağlar orthotopic xenograft modelinin üretimi açıklayın.
EVs tümör ve stromal hücreler14arasındaki hücreler arası iletişim çok önemli arabulucu vardır. EVs kökenli proteinler, lipidler ve gen düzenlemesinde de dahil olmak üzere hücrenin fonksiyonel biomolecules taşırlar. Ekstrasellüler alanda serbest sonra bu veziküller çevreleyen hücreleri tarafından alınabilir veya kan veya lenf dolaşımını üzerinden uzak sitelere yapılan ve hedef hücre davranış derinden etkileyebilir. 15 , 16 , 17 Mesela kanser EVs stromal fibroblastlar tarafından alımını angiogenez destekleyen ve tümör büyüme vivo içinde18,19, endotel tarafından içselleştirilmesi hızlanan myofibroblast ayrımında neden olabilir hücreler tümör angiogenez teşvik etmek ve vasküler geçirgenliği16,20artırmak ve bağışıklık hücreleri ile etkileşim antitümör bağışıklık yanıtı21bastırılması için neden olabilir.
Son zamanlarda biz, osteosarkom, tümör hücreleri tumorigenic pro ve pro-metastatik fenotip elde etmek için MSCs sor EVs yüksek miktarda serbest bir kollarındaki orthotopic xenograft fare modeli kullanarak gösterilmiştir. Bu efekt ("Yüksek lisans eğitim" anılacaktır) MSC sitokin ifade profil dramatik bir değişim kaynaklanmaktadır ve bir terapötik İnterlökin-6 reseptörü (IL-6R) antikor7yönetimi tarafından engellenebilir. Çalışmalarımız kanser EVs MSC davranış, böylece microenvironment hedefli yaklaşımlar osteosarkom ilerleme durdurmak için bir gerekçe sağlayan çok önemli modülatörler olduğunu gösterdi. Burada, EV-aracılı tümör-MSC etkileşim içinde vivoaraştırmak için adım adım bir protokol açıklar. Bu model için tasarlanmıştır: 1) özellikle kanser EV kaynaklı değişikliklere MSC davranışının tümör microenvironment define, 2) nasıl bu etkileşim katkıda kemik tümörü büyümesi ve metastaz oluşumu ve 3) çalışma için engel olup olmadığını değerlendirmek EV-aracılı crosstalk vivo içinde kanser ilerleme engeller.

a preclinical mouse model of osteosarcoma to define the extracellular vesicle-mediated communication between tumor and mesenchymal stem cells

Tümör microenvironment içinde ikamet veya işe Mezenkimal Kök hücre (MSCs) birden çok kanser türü Malign ilerlemesinde katkıda bulunur. Belirli çevre sinyalleri etkisi altında bu yetişkin kök hücreler lider hızlandırılmış tümör büyüme ve metastaz parakrin arabulucu serbest bırakabilirsiniz. Tümör ve MSCs arasında çapraz karışma tanımlama kanser ilerleme yatan mekanizmaları anlamak ve terapötik müdahale için yeni hedefler belirlemek için birincil önem taşımaktadır.
Kanser hücrelerinin derinden hedef hücreler tümör microenvironment veya uzak sitelerdeki davranışını etkileyebilir ekstraselüler veziküller (EVs), yüksek miktarlarda üretmek. Tümör EVs fonksiyonel biomolecules inflamatuar RNA'ların ve stromal hücreler kanser hücrelerinin metastatik davranış geliştirmek için veya önceden metastatik niş oluşumunda katılmak için eğitmek olabilir (onko) proteinler, dahil olmak üzere, alın. Bu makalede, belirli tümör ve Mezenkimal Kök hücreler arasındaki EV-aracılı crosstalk değerlendirilmesi sağlayan bir preklinik kanser fare modeli geliştirilmesi açıklar. İlk olarak, arıtma ve tümör salgılanan EVs karakterizasyonu ve EV içselleştirilmesi MSCs tarafından değerlendirilmesi açıklanmaktadır. Biz o zaman yapmak MSC sitokin ifade profil İLETİMLERİNİZE değerlendirmek için çok katmanlı bir boncuk tabanlı immunoassay kullanımı kanseri EVs tarafından indüklenen. Son olarak, biz bir tümör-MSC etkileşim beyannamedir osteosarkom kollarındaki orthotopic xenograft fare modeli nesil göstermek ve EV eğitimli MSCs tümör büyüme ve metastaz oluşumu için katkı göstermek.
Bizim model nasıl kanser EVs tümör destekleyen bir ortam şekli tanımlamak ve abluka tümör ve MSCs arasındaki EV-aracılı iletişim kanser ilerleme engeller olup olmadığını değerlendirmek için fırsat sağlar.

Bu çalışmada, osteosarkom salgılanan EVs MSCs pro tumorigenic ve pro-metastatik fenotip doğru eğitmek yeteneğini keşfettik. Biz osteosarkom hücreleri MSCs tarafından içselleştirilmiş eksozom benzeri EVs yayın gösterir. Biz kanser EVs tarafından indüklenen MSC sitokin ifade profil İLETİMLERİNİZE ölçülen ve EV eğitimli MSCs tümör büyüme ve metastaz oluşumu üzerinde etkisi değerlendirilir.

A Preclinical Mouse Model of Osteosarcoma to Define the Extracellular Vesicle-mediated Communication Between Tumor and Mesenchymal Stem Cells

Tümör ve Mezenkimal Kök hücreler arasında ekstrasellüler vezikül aracılı iletişim tanımlamak için osteosarkom preklinik fare modeli

Hücre dışı veziküller (EVs) kanser kaynaklı direkt enjeksiyon kemik iliği tümör ilerleme destekleyen yeniden programlama için yol açar; Ancak, bu etkinin hangi hücrelerin aracılık belli değildir. Burada, biz EV-aracılı tümör Mezenkimal Kök hücre (MSC) etkileşimleri vivo içindearaştırmak için adım adım bir protokol için EV eğitimli MSCs metastaz içinde çok önemli bir rol açığa tanımlamak.

Within the tumor microenvironment, resident or recruited mesenchymal stem cells (MSCs) contribute to malignant progression in multiple cancer types. Under ...
