iPS向*細胞定向分化操作系統(tǒng)

(Cellartis iPS Cell to Hepatocyte Differentiation System)

以*細胞為模型的實驗越來越受到重視，在*病變機理研究、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)?；貙崿F(xiàn)iPS向hepatocyte的誘導轉(zhuǎn)化生產(chǎn)，而且誘導轉(zhuǎn)化出的肝細胞能夠穩(wěn)定表達藥物代謝相關(guān)酶系統(tǒng)和藥物轉(zhuǎn)運系統(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進行標準化操作。使用本產(chǎn)品的過程起始于誘導人iPS轉(zhuǎn)化成為確定性內(nèi)胚層（Definitive Endoderm (DE)）細胞，然后誘導轉(zhuǎn)化DE至肝細胞。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 肝細胞（大約50 cm²面積的單層貼壁細胞）。

利用Cellartis iPS Cell to Hepatocyte Differentiation System轉(zhuǎn)化得到的肝細胞除了清晰表現(xiàn)出肝細胞的*特征外（如肝細胞特異性標志物、CYP系列酶等），還保留了原始細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*細胞（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。這一點對于毒理學評估和病毒感染評估具有顯著的意義。為長時間維持培養(yǎng)hiPS轉(zhuǎn)化而來的肝細胞，我們推薦Cellartis Hepatocyte Maintenance Medium (Cat. No. Y30051)。

■ Cellartis iPS Cell to Hepatocyte Differentiation System 產(chǎn)品特點

· 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.

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).
