Kanser terapötik olarak etkili geliştirilmesi son derece zor olduğu kanıtlanmıştır. Kanser hücre hatları ve tümör eksplant - hem de ksenograftları üzerinde yarım asır 1,2,3 kanser araştırmalarında kullanılmıştır. Bugüne kadar, ilaç hassasiyeti ve mukavemet hem de kurulmuş olan kanser hücre çizgileri ve hasta türetilmiş ksenograftlarının moleküler analizi (PDX) vazgeçilmezdir. Bununla birlikte, sabitlenen kanser hücresi hatlarında bileşiklerin testleri çoğu zaman in vivo etkinliğe işaret eden değildir ve özellikle de PDX modellerinde, hayvanlarda in vivo çalışmalarda da karşılık gelen çok pahalı ve zaman alıcı bir işlemdir. Bu model sistemlerde, tümör ilerlemesi ve tedavi stratejileri yanıt yerli mikroçevresinin etkisi hakkında bilgilendirmek için yani yetersizlik sınırlamalar, bu analizleri iltifat için ek yöntemler geliştirmek araştırma alanını açmıştır. Yakın zamandaki, artan dikkat hasta tum ex vivo analizi doğru ödeniyorKanser terapötik cevap, kanser hücrelerinin temel molekül bileşime özel değildir ama daha çok büyük, geleneksel yöntemler ile kültürleme değinmeyecek edilemez tümör hücresi mikro-6, 7 özelliği etkilenir olmasından dolayı daha iyi anlaşılması için eksplantlar ya da 4, 5 / veya PDX. yukarıdaki bağlamda ex vivo analizi (yani., bitişik çevreleyen tümör hücre mikro-etkisi) daha çok hücre izolatları 8, 9 ex vivo analizine göre, uygun bir primer tümör / metastaz bölme değerlendirilmesini gerektirir. Biz de hasta primer tümörlerin (hassas dilimlenmiş taze doku bölümleri yani.) Ve ilişkili metastazlar (yani, lenf düğümleri) sadakatle yanıt üzerine bilgilendirir (IC50), hedef dışı etkileri bir ex vivo tekniği burada rapor ve moleküler sağlar direnci ve geri besleme mekanizmalarının analizi. Fototerapi ek olarak, bir analiz bağıntılıbiyomarkör ve gen ekspresyon profilinin karşı utic duyarlılık / direnç (yani., yüksek ilaç tepkisi belirli bir biyolojik profil ile hastayı maçları) ilgi deneysel ilaca cevap daha muhtemel hastaları belirlemek için bir çaba yapılabilir. Bir çok parametre moda ex vivo tekniği ve değerlendirme uygulama hasta seçimi ve klinik sonuçların genel iyileştirilmesine yönelik bir harekettir. Ex vivo tedavi yanıtı analizi kanser tedavileri klinik öncesi ve klinik geliştirme standart bir araç haline gelebilir ve tedavi kalkınma stratejilerinde kişiselleştirilmiş tıp yaklaşımına doğru bir adım olarak tasavvur edilir.

ex vivo treatment response of primary tumors and/or associated metastases for preclinical and clinical development of therapeutics

The molecular analysis of established cancer cell lines has been the mainstay of cancer research for the past several decades. Cell culture provides both direct and rapid analysis of therapeutic sensitivity and resistance. However, recent evidence suggests that therapeutic response is not exclusive to the inherent molecular composition of cancer cells but rather is greatly influenced by the tumor cell microenvironment, a feature that cannot be recapitulated by traditional culturing methods. Even implementation of tumor xenografts, though providing a wealth of information on drug delivery/efficacy, cannot capture the tumor cell/microenvironment crosstalk (i.e., soluble factors) that occurs within human tumors and greatly impacts tumor response. To this extent, we have developed an ex vivo (fresh tissue sectioning) technique which allows for the direct assessment of treatment response for preclinical and clinical therapeutics development. This technique maintains tissue integrity and cellular architecture within the tumor cell/microenvironment context throughout treatment response providing a more precise means to assess drug efficacy.

Bu çalışma için, ex vivo olarak teknik, bir ısı şoku proteini 90 inhibitörleri (Hsp90i) terapötik hassaslık / duyarlılık bir bağıntılı analizinde kullanıldı.
