| 1 | Transcriptomic 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 | 2019 | Genes & Diseases2019，6，3： | 11 |
| 2 | Highly expressed BMP9/GDF2 in postnatal mouse liver and lungs may account for its pleiotropic effects on stem cell differentiation,angiogenesis,tumor growth and metabolism显示文摘Bone morphogenetic protein 9(BMP9)(or GDF2)was originally identified from fetal mouse liver cDNA libraries.Emerging evidence indicates BMP9 exerts diverse and pleiotropic functions during postnatal development and in maintaining tissue homeostasis.However,the expression landscape of BMP9 signaling during development and/or in adult tissues remains to be analyzed.Here,we conducted a comprehensive analysis of the expression landscape of BMP9 and its signaling mediators in postnatal mice.By analyzing mouse ENCODE transcriptome datasets we found Bmp9 was highly expressed in the liver and detectable in embryonic brain,adult lungs and adult placenta.We next conducted a comprehensive qPCR analysis of RNAs isolated from major mouse tissues/organs at various ages.We found that Bmp9 was highly expressed in the liver and lung tissues of young adult mice,but decreased in older mice.Interestingly,Bmp9 was only expressed at low to modest levels in developing bones.BMP9-associated TGFβ/BMPR type I receptor Alk1 was highly expressed in the adult lungs.Furthermore,the feedback inhibitor Smads Smad6 and Smad7 were widely expressed in mouse postnatal tissues.However,the BMP signaling antagonist noggin was highly expressed in fat and heart in the older age groups,as well as in kidney,liver and lungs in a biphasic fashion.Thus,our findings indicate that the circulating BMP9 produced in liver and lungs may account for its pleiotropic effects on postnatal tissues/organs although possible roles of BMP9 signaling in liver and lungs remain to be fully understood. | Wei Liu Zhongliang Deng Zongyue Zeng Jiaming Fan Yixiao Feng Xi Wang Daigui Cao Bo Zhang Lijuan Yang Bin Liu Mikhail Pakvasa William Wagstaff Xiaoxing Wu Huaxiu Luo Jing Zhang Meng Zhang Fang He Yukun Mao Huiming Ding Yongtao Zhang Changchun Niu Rex C.Haydon Hue H.Luu Jennifer Moriatis Wolf Michael J.Lee Wei Huang Tong-Chuan He Yulong Zou | 2020 | Genes & Diseases2020，7，2： | 9 |
| 3 | Microvesicles(MIVs)secreted from adipose-derived stem cells(ADSCs)contain multiple microRNAs and promote the migration and invasion of endothelial cells显示文摘Extracellular vesicles(EVs)such as microvesicles(MIVs)play an important role in intercellular communications.MIVs are small membrane vesicles sized 100e1000 nm in diameter that are released by many types of cells,such as mesenchymal stem cells(MSCs),tumor cells and adipose-derived stem cells(ADSC).As EVs can carry out autocrine and paracrine functions by controlling multiple cell processes,it is conceivable that EVs can be used as delivery vehicles for treating several clinical conditions,such as to improve cardiac angiogenesis after myocardial infarction(MI).Here,we seek to investigate whether ADSC-derived MIVs contain microRNAs that regulate angiogenesis and affect cell migration of endothelial cells.We first characterized the ADSC-derived MIVs and found that the MIVs had a size range of 100 e300 nm,and expressed the MIV marker protein Alix.We then analyzed the microRNAs in ADSCs and ADSC-derived MIVs and demonstrated that ADSC-derived MIVs selectively released a panel of microRNAs,several of which were related to angiogenesis,including two members of the let-7 family.Furthermore,we demonstrated that ADSC-derived MIVs promoted the cell migration and invasion of the HUVEC endothelial cells.The PKH26-labeled ADSC-derived MIVs were effectively uptaken into the cytoplasm of HUVEC cells.Collectively,our results demonstrate that the ADSC-derived MIVs can promote migration and invasion abilities of endothelial cells,suggesting pro-angiogenetic potential.Future studies should focus on investigating the roles and mechanisms through which ADSC-derived MIVs regulate angiogenesis. | Bo Huang Lin-Feng Huang Ling Zhao Zongyue Zeng Xi Wang Daigui Cao Lijuan Yang Zhenyu Ye Xian Chen Bin Liu Tong-Chuan He Xiaozhong Wang | 2020 | Genes & Diseases2020，7，2： | 8 |
| 4 | Stem cell therapy for chronic skin wounds in the era of personalized medicine:From bench to bedside显示文摘With the significant financial burden of chronic cutaneous wounds on the healthcare system,not to the personal burden mention on those individuals afflicted,it has become increasingly essential to improve our clinical treatments.This requires the translation of the most recent benchtop approaches to clinical wound repair as our current treatment modalities have proven insufficient.The most promising potential treatment options rely on stem cellbased therapies.Stem cell proliferation and signaling play crucial roles in every phase of the wound healing process and chronic wounds are often associated with impaired stem cell function.Clinical approaches involving stem cells could thus be utilized in some cases to improve a body’s inhibited healing capacity.We aim to present the laboratory research behind the mechanisms and effects of this technology as well as current clinical trials which showcase their therapeutic potential.Given the current problems and complications presented by chronic wounds,we hope to show that developing the clinical applications of stem cell therapies is the rational next step in improving wound care. | Elam Coalson Elliot Bishop Wei Liu Yixiao Feng Mia Spezia Bo Liu Yi Shen Di Wu Scott Du Alexander J.Li Zhenyu Ye Ling Zhao Daigui Cao Alissa Li Ofir Hagag Alison Deng Winny Liu Mingyang Li Rex C.Haydon Lewis Shi Aravind Athiviraham Michael J.Lee Jennifer Moriatis Wolf Guillermo A.Ameer Tong-Chuan He Russell R.Reid | 2019 | Genes & Diseases2019，6，4： | 6 |

| 6 | Cloud-based smartphone-assisted chemiluminescent assay for rapid screening of electroactive bacteria显示文摘Electroactive bacteria(EAB)can transfer electrons to exocellular solid acceptors and have widespread applications in the fields of pollutant degradation,biosynthesis,and hydrogen generation.Traditional EAB screening methods can precisely measure the bacterial extracellular electron transfer ability,but they suffer from time-consuming and labor-intensive procedures.The chemiluminescence technique is effective for the rapid detection of hemoglobin but has not been applied for EAB screening.Herein,we utilized a chemiluminescent assay to identify EAB through a multiheme c-type cytochrome(c-Cyt)triggered chemiluminescent reaction.The multiheme c-Cyts-triggered chemiluminescence was conveniently determined by taking photographs with commercial smartphones and cloud-based computing.The acquired image signal shows a significant and linear relationship with the bacterial concentration.Measurement results of the chemiluminescence intensity triggered by different bacterial species with the proposed method are strongly associated with those of the microplate reading method(Pearson’s r of 0.9795;P<0.01)and dissimilatory Fe(Ⅲ)reduction method(Pearson’s r of 0.9628;P<0.01).Furthermore,this cloud-based and smartphone-assisted chemiluminescent assay is instrument-free and easy to operate,and results can be obtained within 2 min.The findings demonstrate that the proposed method can effectively detect EAB.Therefore,it will be an alternative approach for EAB screening and can have promising applications in microbiology,environmental science,and bioenergy. | WEN JunLin HE DaiGui LUO SongQing ZHOU ShunGui YUAN Yong | 2023 | Science China(Technological Sciences)2023，66，3： | 1 |
