iPS向肝臟細(xì)胞定向分化操作系統(tǒng)
(Cellartis iPS Cell to Hepatocyte Differentiation System)
以肝臟細(xì)胞為模型的實(shí)驗(yàn)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(shí)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(shí)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(shí)驗(yàn)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)胞的必備特征外(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(diǎn)對于毒理學(xué)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(xì)胞,我們推薦Cellartis Hepatocyte Maintenance Medium (Cat. No. Y30051)。

詳情
 
■ 產(chǎn)品特點(diǎn)
· 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).

訪談時間:
1. 開始使用Cellartis iPS Cell to Hepatocyte Differentiation System(Y30055)的契機(jī)是什么?
很多研究組已經(jīng)報道了多種從人iPS細(xì)胞誘導(dǎo)分化形成肝臟細(xì)胞的方法,我們研究組也在做相關(guān)工作。由于細(xì)胞分化不穩(wěn)定,我擔(dān)心使用飼養(yǎng)層細(xì)胞培養(yǎng)人iPS細(xì)胞會對肝臟分化產(chǎn)生影響,因此決定嘗試使用Cellartis iPS細(xì)胞無飼養(yǎng)層培養(yǎng)系統(tǒng)Cellartis DEF-CS™ 500 Culture System(Y30010)和肝臟分化系統(tǒng)Cellartis iPS Cell to Hepatocyte Differentiation System(Y30055)
 
2.實(shí)際使用后感覺如何?
與之前使用的飼養(yǎng)層培養(yǎng)方法相比,Y30010能更簡便高效的進(jìn)行培養(yǎng);使用Y30055進(jìn)行的肝臟分化非常穩(wěn)定,進(jìn)一步提升了實(shí)驗(yàn)效率。
 
3. 對暫未使用該制品的用戶有什么寄語?
人iPS細(xì)胞向肝臟細(xì)胞分化過程中,細(xì)胞密度對分化效率有很大影響,進(jìn)而影響實(shí)驗(yàn)結(jié)果。我認(rèn)為Cellartis系統(tǒng)的優(yōu)點(diǎn)主要在于各個實(shí)驗(yàn)階段偏差小,結(jié)果穩(wěn)定,適合追求實(shí)驗(yàn)效率的人。

訪談時間:
1.開始使用Cellartis iPS Cell to Hepatocyte Differentiation System(Y30055)的契機(jī)是什么?
一起進(jìn)行研究的老師使用后能夠進(jìn)行穩(wěn)定的培養(yǎng),我們研究室也正好想利用無飼養(yǎng)層培養(yǎng)系統(tǒng),所以開始使用了Cellartis DEF-CS™ 500 Culture System(Y30010)和肝臟分化系統(tǒng)Cellartis iPS Cell to Hepatocyte Differentiation System(Y30055)
 
2.實(shí)際使用后感覺如何?
Y30010無飼養(yǎng)層培養(yǎng)系統(tǒng)使用比較簡便,同時能夠穩(wěn)定的培養(yǎng)人iPS細(xì)胞。這次實(shí)驗(yàn)中,利用Y30055分化至肝前體細(xì)胞(iPS-HPCs),進(jìn)一步誘導(dǎo)分化成了膽管細(xì)胞,我認(rèn)為誘導(dǎo)分化的再現(xiàn)性好。不僅分化至成熟肝細(xì)胞譜系,同時相比于以往報道的方法,再現(xiàn)性更穩(wěn)定。
 
3. 對暫未使用該制品的用戶有什么寄語?
在人iPS細(xì)胞的培養(yǎng)和分化至肝細(xì)胞譜系的誘導(dǎo)中,即使是對人iPS細(xì)胞使用經(jīng)驗(yàn)尚淺的實(shí)驗(yàn)者,也能夠進(jìn)行培養(yǎng)并得到穩(wěn)定的再現(xiàn)。
