BioVector? NTCC? LU2511大細(xì)胞未分化肺癌異種移植（PDX）模型

BioVector? LU2511指的是一個(gè)患者來源的異種移植（PDX）模型，而非傳統(tǒng)的體外細(xì)胞系。這是一個(gè)在小鼠體內(nèi)生長(zhǎng)的肺癌模型。
LU2511 PDX模型的主要特點(diǎn)
來源：該模型源自一位49歲女性患者的大細(xì)胞未分化肺癌。
組織來源：樣本取自患者的肺部。
組織病理學(xué)：對(duì)腫瘤組織的病理學(xué)分析證實(shí)其為大細(xì)胞未分化癌。腫瘤塊的描述為7厘米 x 6厘米 x 6厘米。
免疫組織化學(xué)（IHC）：腫瘤的標(biāo)志物染色結(jié)果顯示CK和EMA呈陽性，而Vim和CK7呈陰性。同時(shí)，Syn呈陽性，CD56呈陰性。P63染色較弱。
腫瘤生長(zhǎng)：PDX模型在Balb/c裸鼠體內(nèi)生長(zhǎng)，用于體內(nèi)研究這類肺癌的生物學(xué)特征。
研究應(yīng)用
轉(zhuǎn)化研究：LU2511模型用于在活體系統(tǒng)中研究人類肺癌的生長(zhǎng)和進(jìn)展。
藥物篩選：用于測(cè)試新的癌癥治療方法，特別是針對(duì)大細(xì)胞未分化癌的治療。
腫瘤微環(huán)境研究：該模型可以在體內(nèi)研究復(fù)雜的腫瘤微環(huán)境和轉(zhuǎn)移。
什么是PDX模型？
PDX模型是通過將患者的人類腫瘤組織直接植入免疫缺陷小鼠體內(nèi)而創(chuàng)建的。與在實(shí)驗(yàn)室培養(yǎng)皿中體外生長(zhǎng)的細(xì)胞系不同，PDX模型保留了原始腫瘤的大部分特征，包括其遺傳異質(zhì)性、組織病理學(xué)和腫瘤微環(huán)境。這使得PDX模型成為臨床前癌癥研究的重要工具，因?yàn)樗鼈儽葌鹘y(tǒng)的細(xì)胞系更能準(zhǔn)確地模擬人類癌癥。
BioVector? LU2511 refers to a patient-derived xenograft (PDX) model, not a traditional in vitro cell line. It is a lung cancer model that is grown in mice.
Key characteristics of the LU2511 PDX model
Origin: The model was derived from a 49-year-old female patient with a large cell undifferentiated lung carcinoma.
Source tissue: The sample was taken from the patient's lung.
Histopathology: Pathological analysis of the tumor tissue confirmed it to be a large cell undifferentiated carcinoma. The tumor mass was described as being 7cm x 6cm x 6cm.
Immunohistochemistry (IHC): The tumor was positive for the markers CK and EMA, and negative for Vim and CK7. It was also positive for Syn and negative for CD56. P63 staining was weak.
Tumor growth: The PDX model is grown in Balb/c nu mice and is used to study the biological features of this type of lung cancer in vivo.
Research applications
Translational research: The LU2511 model is used to investigate the growth and progression of human lung cancer in a living system.
Drug screening: It is used to test the efficacy of new cancer treatments, especially those targeting large cell undifferentiated carcinoma.
Tumor microenvironment studies: The model allows for the study of the complex tumor microenvironment and metastasis in vivo.
What is a PDX model?
A PDX model is created by implanting human tumor tissue from a patient directly into an immunodeficient mouse. Unlike a cell line, which is grown in vitro in a lab dish, the PDX model maintains much of the original tumor's characteristics, including its genetic heterogeneity, histopathology, and tumor microenvironment. This makes PDX models a valuable tool for preclinical cancer research, as they more accurately mimic human cancer than traditional cell lines.
