2Transcriptomic landscape regulated by the 14 types of bone morphogenetic proteins(BMPs)in lineage commitment and differentiation of mesenchymal stem cells(MSCs)显示文摘Mesenchymal stem cells(MSCs)are ubiquitously-existing multipotent progenitors that can self-renew and differentiate into multiple lineages including osteocytes,chondrocytes,adipocytes,tenocytes and myocytes.MSCs represent one of the most commonly-used adult progenitors and serve as excellent progenitor cell models for investigating lineagespecific differentiation regulated by various cellular signaling pathways,such as bone morphogenetic proteins(BMPs).As members of TGFb superfamily,BMPs play diverse and important roles in development and adult tissues.At least 14 BMPs have been identified in mammals.Different BMPs exert distinct but overlapping biological functions.Through a comprehensive analysis of 14 BMPs in MSCs,we demonstrated that BMP9 is one of the most potent BMPs in inducing osteogenic differentiation of MSCs.Nonetheless,a global mechanistic view of BMP signaling in regulating the proliferation and differentiation of MSCs remains to be fully elucidated.Here,we conducted a comprehensive transcriptomic profiling in the MSCs stimulated by 14 types of BMPs.Hierarchical clustering analysis classifies 14 BMPs into three subclusters:an osteo/chondrogenic/adipogenic cluster,a tenogenic cluster,and BMP3 cluster.We also demonstrate that six BMPs(e.g.,BMP2,BMP3,BMP4,BMP7,BMP8,and BMP9)can induce ISmads effectively,while BMP2,BMP3,BMP4,BMP7,and BMP11 up-regulate Smad-independent MAP kinase pathway.Furthermore,we show that many BMPs can upregulate the expression of the signal mediators of Wnt,Notch and PI3K/AKT/mTOR pathways.While the reported transcriptomic changes need to be further validated,our expression profiling represents the first-of-its-kind to interrogate a comprehensive transcriptomic landscape regulated by the 14 types of BMPs in MSCs.Linghuan Zhang Qing Luo Yi Shu Zongyue Zeng Bo Huang Yixiao Feng Bo Zhang Xi Wang Yan Lei Zhenyu Ye Ling Zhao Daigui Cao Lijuan Yang Xian Chen Bin Liu William Wagstaff Russell R*Reid Hue H*Luu Rex C*Haydon Michael J*Lee Jennifer Moriatis Wolf Zhou Fu Tong-Chuan He Quan Kang 2019Genes & Diseases2019,6,3:11
3Further geological and palaeoanthropological investigations at the Maludong hominin site, Yunnan Province, Southwest China显示文摘Three-dimensional mapping and section work undertaken by us in 2008 have identified 11 stratigraphic units at Maludong site.AMS radiocarbon dating of charcoal established an accurate and internally consistent age profile for the sequence of 17.8±0.2 ka to 13.2±0.1 ka.Archaeomagnetic analysis showed changes in externally derived pedogenically enhanced material consistent with a warming in climate between the cold period of Henrich Event 1 and the B lling-Aller d interstadial.Human remains recovered during the 1989 excavation were derived from a deposit dating to this interstadial,or between 14.3±0.3 ka and 13.5±0.1 ka.Anthropogenic features,including burnt rocks,baked sediment and thick charcoal and ash layers,were identified and examined through archaeomagnetic analysis.Two monkey fossils are described here,one of them being reassigned from Macaca robustus to M.aff.M.assamensis.They confirm the young age of the site and also show signs of anthropogenic alteration in the form of burning.Additional human cranial remains are reported for the first time and new data are provided for some specimens described previously.A range of new features is identified that strengthen the affinities of the Maludong remains to archaic humans.The presence of this globally unique mosaic of archaic and modern features raises important questions about human evolutionary history in East Asia during the Late Upper Pleistocene.JI XuePing CURNOE Darren BAO ZhenDe HERRIES Andy I R FINK David ZHU YunSheng HELLSTROM John LUO Yun TACON Paul S C 2013Chinese Science Bulletin2013,58,35:3
4Terahertz Semiconductor Quantum Well Devices显示文摘For eventually providing terahertz science with compact and convenient devices,terahertz (1~10THz) quantum-well photodetectors and quantum-cascade lasers are investigated.The design and projected detector performance are presented together with experimental results for several test devices,all working at photon energies below and around optical phonons.Background limited infrared performance (BLIP) operations are observed for all samples (three in total),designed for different wavelengths.BLIP temperatures of 17,13,and 12K are achieved for peak detection frequencies of 9.7THz(31μm),5.4THz(56μm),and 3.2THz(93μm),respectively.A set of THz quantum-cascade lasers with identical device parameters except for doping concentration is studied.The δ-doping density for each period varies from 3.2×1010 to 4.8×1010cm-2.We observe that the lasing threshold current density increases monotonically with doping concentration.Moreover,the measurements for devices with different cavity lengths provide evidence that the free carrier absorption causes the waveguide loss also to increase monotonically.Interestingly the observed maximum lasing temperature is best at a doping density of 3.6×1010cm-2.Liu H C Luo H Ban D Waichter M Song C Y Wasilewski Z R Buchanan M Aers G C SpringThorpe A J Cao J C Feng S L Williams B S Hu Q 2006Journal of Semiconductors2006,27,4:2
