        意大利塔拉莫大學(xué)的Angelo Canciello等在2017年6月19日的《自然》雜志發(fā)表的《孕酮預(yù)防綿羊羊膜上皮細胞上皮-間質(zhì)轉(zhuǎn)化和提高他們的免疫調(diào)節(jié)特性》一文中,提供了孕酮(P4)預(yù)防綿羊羊膜上皮細胞(oAEC)上皮-間質(zhì)轉(zhuǎn)化(EMT)的分子學(xué)證據(jù)。在測定細胞因子TGF- β、IL-4和IL-10的表達時,他們采用了基諾萊斯生物科技有限公司的相關(guān)ELISA試劑盒,并在文章中的兩處做了引用注明。

         具體引用情況如下:
        “在標(biāo)準(zhǔn)條件下擴增的oAEC通過上調(diào)EMT轉(zhuǎn)錄因子自發(fā)獲得間質(zhì)特性, 通過抑制EMT誘導(dǎo)機制比如TGF- β的自分泌(定量測定采用基諾萊斯科技有限公司生產(chǎn)的Nori Sheep TGF-β3 ELISA試劑盒)和細胞內(nèi)相關(guān)信號的活化, P4可以阻止這種表型的變化。從細胞培養(yǎng)基中去掉P4然后細胞傳代一次,P4的這種作用仍然存在,并且P4可以很快逆轉(zhuǎn)擴增中正在進行EMT轉(zhuǎn)化的oAEC間質(zhì)表型。此外,P4促進多能行基因的急性上調(diào)進而提高基底和LPS誘導(dǎo)的oAEC抗炎反應(yīng),表現(xiàn)為抗炎細胞因子表達增加(定量測定采用基諾萊斯科技有限公司生產(chǎn)的Nori Sheep IL-4 and IL-10 ELISA試劑盒)和促炎性細胞因子表達降低。綜合上述結(jié)果,P4對于維持oAEC的上皮表型提高其生物學(xué)特性至關(guān)重要,因此,為了提高這種上皮干細胞的治療潛力,我們提出了一種新的細胞培養(yǎng)方法。”
        《自然》雜志在國際上影響力巨大,其影響因子高達38.138,基諾萊斯產(chǎn)品被其引用有重大的現(xiàn)實意義,標(biāo)志著公司免疫分析技術(shù)已達到世界先進水平,產(chǎn)品質(zhì)量也得到國際上的充分肯定,極大地提升了公司的知名度,有助于公司產(chǎn)品得到更好的推廣和發(fā)展。目前,基諾萊斯正在推行心梗早期預(yù)警診斷項目,預(yù)計相關(guān)產(chǎn)品將在兩年內(nèi)問世?;Z萊斯將不斷向成為心血管病早期預(yù)警診斷一體化POCT智能系統(tǒng)供應(yīng)商的目標(biāo)奮進,為推動我國大健康產(chǎn)業(yè)發(fā)展做出積極貢獻。

 The in vitro expansion is detrimental to therapeutic applications of amniotic epithelial cells (AEC), an emerging source of fetal stem cells. This study provides molecular evidences of progesterone (P4) role in preventing epithelial-mesenchymal transition (EMT) in ovine AEC (oAEC). oAEC amplified under standard conditions spontaneously acquired mesenchymal properties through the up-regulation of EMT-transcription factors. P4 supplementation prevented phenotype shift by inhibiting the EMT inducing mechanism such as the autocrine production of TGF-β (quantified by Nori Sheep TGF-β3 ELISA Kit, Genorise Scientific, Inc.) and the activation of intracellular related signaling. The effect of P4 still persisted for one passage after steroid removal from culture as well as steroid supplementation promptly reversed mesenchymal phenotype in oAEC which have experienced EMT during amplification. Furthermore, P4 promoted an acute up-regulation of pluripotent genes whereas enhanced basal and LPS-induced oAEC anti-inflammatory response with an increase in anti-inflammatory (quantified by Nori Sheep IL-4 and IL-10 ELISA Kits, Genorise Scientific, Inc.) and a decrease in pro-inflammatory cytokines expression. Altogether, these results indicate that P4 supplementation is crucial to preserve epithelial phenotype and to enhance biological properties in expanded oAEC. Therefore, an innovative cultural approach is proposed in order to improve therapeutic potential of this promising source of epithelial stem cells.
