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). | |||||||||||||||||

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)一步提升了實驗效率。 | |||||||||||||||||
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)而影響實驗結(jié)果。我認(rèn)為Cellartis系統(tǒng)的優(yōu)點主要在于各個實驗階段偏差小,結(jié)果穩(wěn)定,適合追求實驗效率的人。 | |||||||||||||||||

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。這次實驗中,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)驗尚淺的實驗者,也能夠進(jìn)行培養(yǎng)并得到穩(wěn)定的再現(xiàn)。 | |||||||||||||||||
