| 1 | Derivation of hypermethylated pluripotent embryonic stem cells with high potency显示文摘天真的 hypomethylated 胚胎的 pluripotent 干细胞(转换字符) 离胚囊的 preimplantation epiblast 发展地最靠近,与潜力到贡献所有胚胎的纸巾和 germline,除了在妄想的胚胎的胚胎外的纸巾。由对比,类似于 postimplantation epiblast 的 epiblast 干细胞(EpiSCs ) 是相对更多的 methylated 和表演为 chimerism 的一个有限潜力。第一次,这里,我们在 pluripotent 房间以外发展地揭示先进 pluripotent 干细胞(ASC ) ,它是在内部房间团中,但是与更高的力量比 EpiSCs。因此,单个 ASC 在怪物很高效地作出贡献到胎儿, germline,蛋黄囊和胎盘的迷宫。因为他们是,发展地,更多进展了, ASC 不贡献 trophoblast。ASC 在与 Activin A 和基本成纤维细胞生长因素补充的化学上定义的媒介在二个步骤从胚囊被导出,在包含 ActA, BMP4, CHIR99021 和白血病的 ABCL 媒介由 culturing 列在后面禁止的因素。尤其是, ASC 与天真的 pluripotency 基因,以及 mesodermal 的表示展出不同 transcriptome 体的基因;Eomes,时代, Tdgf1, Evx1, hand1, Wnt5a 和不同重复元素。到 ASC 的确定的转换字符的变换也是可完成的。重要地, ASC 作为与 hypomethylated 相比展出稳定的 hypermethylated epigenome 和主要未经触动的印记胚囊和天真的转换字符的内部房间质量。ASC 的性质建议他们以在 pluripotency 的天真、告知的状态之间的一个中间的细胞的状态代表房间。 | Siqin Bao Walfred WC Tang Baojiang Wu Shinseog Kim Jingyun Li Lin Li Toshihiro Kobayashi Caroline Lee Yanglin Chen Mengyi Wei Shudong Li Sabine Dietmann Fuchou Tang Xihe Li | 2018 | Cell Research2018，28，1： | 4 |
| 2 | Accelerated generation of oligodendrocyte progenitor cells from human induced pluripotent stem cells by forced expression of Sox10 and Olig2显示文摘Oligodendrocyte progenitor cells(OPCs) hold great promise for treatment of dysmyelinating disorders, such as multiple sclerosis and cerebral palsy. Recent studies on generation of human OPCs mainly use human embryonic stem cells(hESCs) or neural stem cells(NSCs) as starter cell sources for the differentiation process. However, NSCs are restricted in availability and the present method for generation of oligodendrocytes(OLs) from ESCs often requires a lengthy period of time. Here, we demonstrated a protocol to efficiently derive OPCs from human induced pluripotent stem cells(hiPSCs) by forced expression of two transcription factors(2TFs), Sox10 and Olig2. With this method, PDGFRα+ OPCs can be obtained in 14 days and O4^+ OPCs in 56 days.Furthermore, OPCs may be able to differentiate to mature OLs that could ensheath axons when co-cultured with rat cortical neurons. The results have implications in the development of autologous cell therapies. | Pengyan Li Mo Li Xihe Tang Shuyan Wang Y.Alex Zhang Zhiguo Chen | 2016 | Science China(Life Sciences)2016，59，11： | 4 |
| 3 | An Outbreak of the SARS-CoV-2 Omicron Variant BA.1—Zhuhai City,Guangdong Province,China,January 13,2022显示文摘On January 13,2022,Zhuhai CDC received a notification that a coronavirus disease 2019(COVID-19)case was found in the fever clinic in nearby Zhongshan City.Zhuhai CDC promptly carried out large-scale population screening in three nearby counties.A total of 4 COVID-19 cases were found in Nanping County.34 cases were screened from close contacts,and 2 cases were reported from close contacts in other cities of Guangdong Province.The 20 cases were sequenced by Guangdong CDC and identified as the variant of concern(VOC)/Omicron variant BA.1.Since January 14,Zhuhai has carried out 8 rounds of nucleic acid screening for COVID-19 in the county where the cases occurred.Four large-scale nucleic acid screening tests for COVID-19 were conducted across the city,and no new community cases were reported after January 15. | Feng Ruan Xuebao Zhang Songjian Xiao Xihe Ni Xiling Yin Zhongwen Ye Guorong Chen Tingting Zhu Zeling Chen Gang Yao Long Chen Sichen Huang Huitao Huang Yi Zhou Heyan Wu Hui Huang Kejing Zhu Shanzi Huang Xiaoou Tang Min Kang Bosheng Li Wenhua Mei | 2022 | China CDC weekly2022，4，30： | 2 |
| 4 | Blastoids generated purely from embryonic stem cells both in mice and humans显示文摘Dear Editor,Embryonic stem cells(ESCs)and trophoblast stem cells(TSCs)are derived from blastocysts(Lu et al.,2001).Blastocyst-like structures(blastoids)are self-assembled structures formed by a combination of ESCs and TSCs(Rivron et al.,2018).To increase the success rate of blastoid formation and its similarity with the features of blastocysts,some reports showed that blastoid could also be derived from a combination of three cell lines,ESCs,TSCs,and extraembryonic endoderm cells(XENs),or novel type of stem cells(Sozen et al.,2018;Weatherbee et al.,2023:Wu et al.,2023;Zhang et al.,2023;Zhang et al.,2019). | Baojiang Wu Yanqiu Wang Jia Yan Mengya Liu Xihe Li Fuchou Tang Siqin Bao | 2024 | Science China(Life Sciences)2024，67，2： | 0 |
| 5 | Comparative characterization of human fetal neural stem cells and induced neural stem cells from peripheral blood mononuclear cells显示文摘Human-induced neural stem cells(iNSCs)transplantation is a potential treatment of neurodegeneration diseases.However,whether the reprogrammed cells have the same characterizations as human fetal neural stem cells needs further exploration.Here we isolated human fetal neural stem cells from aborted 12-week fetal brains and compared with iNSCs reprogrammed from human peripheral blood mononuclear cells in gene expression,proliferation ability,differentiation capacity,and the responses to tumor necrosis factor-α.We found that iNSCs and NSCs both expressed neural stem cell markers Nestin,SOX1,and SOX2.However,only iNSCs can be patterned into dopaminergic neurons and motor neurons.Furthermore,both iNSCs and NSCs can differentiate into oligodendrocyte progenitor cells.In addition,a low dose of tumor necrosis factor-αdid not inhibit the proliferation and differentiation of iNSCs and NSCs.In conclusion,iNSCs have properties similar to,and even better than,fetal neural stem cells and may be suitable for disease modeling and transplantation. | Xihe TANG Meigang YU Rui HUANG Shengyong LAN Yimin FAN | 2020 | BIOCELL2020，44，1： | 0 |
