iPS向肝臟細(xì)胞定向分化試劑盒

產(chǎn)品英文名稱：Cellartis® iPS Cell to Hepatocyte Differentiation System

產(chǎn)品中文名稱：iPS向肝臟細(xì)胞定向分化試劑盒

產(chǎn)品介紹

以肝臟細(xì)胞為模型的實驗越來越受到重視，在肝臟病變機(jī)理研究、藥物代謝研究、藥物毒理評估等方面有廣闊的應(yīng)用前景。然而，以個體原代肝細(xì)胞為材料來源會產(chǎn)生如取材困難、材料批間差大、無法長期穩(wěn)定供應(yīng)等一系列難以克服的問題。因此，通過iPS批量轉(zhuǎn)化生產(chǎn)肝細(xì)胞的方法就顯示出特別的優(yōu)勢。

Cellartis iPS Cell to Hepatocyte Differentiation System可以穩(wěn)定地、規(guī)模化地實現(xiàn)iPS向hepatocyte的誘導(dǎo)轉(zhuǎn)化生產(chǎn)，而且誘導(dǎo)轉(zhuǎn)化出的肝細(xì)胞能夠穩(wěn)定表達(dá)藥物代謝相關(guān)酶系統(tǒng)和藥物轉(zhuǎn)運(yùn)系統(tǒng)。

Cellartis iPS Cell to Hepatocyte Differentiation System是一套Do-It-Yourself系統(tǒng)，客戶既可以對某個特殊病人來源的iPS實現(xiàn)轉(zhuǎn)化，也可以利用cellartis供應(yīng)的iPS進(jìn)行標(biāo)準(zhǔn)化操作。使用本產(chǎn)品的過程起始于誘導(dǎo)人iPS轉(zhuǎn)化成為確定性內(nèi)胚層（Definitive Endoderm (DE)）細(xì)胞，然后誘導(dǎo)轉(zhuǎn)化DE至肝細(xì)胞。本產(chǎn)品是All-In-One型產(chǎn)品，實驗所需的培養(yǎng)基、基質(zhì)（coating）等包括在內(nèi)。應(yīng)用本產(chǎn)品轉(zhuǎn)化約3 × 10⁶ hiPS cells,可以獲得約5 × 10⁶ 肝細(xì)胞（大約50 cm²面積的單層貼壁細(xì)胞）。

利用Cellartis iPS Cell to Hepatocyte Differentiation System轉(zhuǎn)化得到的肝細(xì)胞除了清晰表現(xiàn)出肝細(xì)胞的*特征外（如肝細(xì)胞特異性標(biāo)志物、CYP系列酶等），還保留了原始細(xì)胞供體者的遺傳基因背景。另外，相比較從組織切除獲得的原代肝臟細(xì)胞（通常需要低溫保存），通過本產(chǎn)品系統(tǒng)轉(zhuǎn)化獲得的肝細(xì)胞在更長的時間跨度上保持著生理功能的穩(wěn)定性。這一點對于毒理學(xué)評估和病毒感染評估具有顯著的意義。

產(chǎn)品特點:

高度可重復(fù)性強(qiáng)大的系統(tǒng) - *相同的方法已被證明可用于25種不同的iPS細(xì)胞系，因此無需針對您的細(xì)胞進(jìn)行優(yōu)化。

理想的藥物代謝和安全性研究 - 始終如一地生成具有不同遺傳背景的> 90％純的功能性hiPS細(xì)胞來源的肝細(xì)胞。

定制的起始材料 - 從任何疾病相關(guān)的iPS細(xì)胞系開始，創(chuàng)建準(zhǔn)確的肝臟疾病模型。

準(zhǔn)備好個性化醫(yī)療 - 為治療應(yīng)用制造針對患者的疾病特異性細(xì)胞。

擴(kuò)展實驗窗口 - 肝細(xì)胞可用于功能測試至少11天。

Highly reproducible, robust system—the exact same protocol has been shown to work across 25 different iPS cell lines, so no need to optimize for your lines.

Ideal for drug metabolism and safety studies—consistently generate panels of >90% pure, functional, hiPS cell-derived hepatocytes with diverse genetic backgrounds.

Customized starting materials—start with any disease-relevant iPS cell lines and create accurate liver disease models.

Ready for personalized medicine—make patient-specific, disease-specific cells for therapeutic applications.

Extended experimental window—hepatocytes can be used for a minimum of 11 days for functional tests.

產(chǎn)品性能：

Immunocytochemistry analysis of hepatocyte differentiation. hiPS cells were differentiated into functional hepatocytes using the Cellartis iPS Cell to Hepatocyte Differentiation System. Hepatocytes were immunostained to detect early hepatic markers HNF4α (red, nuclear) and CK18 (green) on days 14 and 21. As the hepatocytes matured, expression of liver-specific markers CYP3A (red, cytoplasmic) and Albumin (green) increased as seen on day 28, as expected. Cell nuclei were stained with DAPI (blue).
