| Abstract | Background State-of-the-art advances have indicated the pivotal characteristics of bone marrow-derived mesenchymal stem/stromal cells (BM-MSCs) in hematopoietic microenvironment as well as coordinate contribution to hematological malignancies. However, the panoramic view and detailed dissection of BM-MSCs in patients with acute myeloid leukemia (AML-MSCs) remain obscure. Methods For the purpose, we isolated and identified AML-MSCs together with healthy donor-derived HD-MSCs from the bone marrow mononuclear cells (BM-MNCs) by using the standard density gradient centrifugation based on clinical diagnosis and cellular phenotypic analysis. Subsequently, we systematically compared the potential similarities and discrepancy both at the cellular and molecular levels via flow cytometry, multilineage differentiation, chromosome karyotyping, cytokine quantification, and transcriptome sequencing and bioinformatic analysis including single-nucleotide polymorphism (SNP), gene ontology (GO), HeatMap, principal component analysis (PCA), Kyoto Encyclopedia of Genes and Genomes (KEGG), and gene set enrichment analysis (GSEA). Results On the one hand, AML-MSCs exhibited undistinguishable signatures in cytomorphology, surface biomarker expression pattern, stemness, chromosome karyotype, and chondrogenesis as HD-MSCs, whereas with impaired adipogenesis, enhanced osteogenesis, and variations in cytokine expression pattern. On the other hand, with the aid of genomic and bioinformatic analyses, we verified that AML-MSCs displayed multidimensional discrepancy with HD-MSCs both in genome-wide gene expression profiling and genetic variation spectrum. Simultaneously, the deficiency of cellular vitality including proliferation and apoptosis in AML-MSCs was largely rescued by JAK-STAT signaling inhibition. Conclusions Overall, our findings elucidated that AML-MSCs manifested multifaceted alterations in biological signatures and molecular genetics, and in particular, the deficiency of cellular vitality ascribed to over-activation of JAK-STAT signal, which collectively provided systematic and overwhelming new evidence for decoding the pathogenesis of AML and exploring therapeutic strategies in future. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
