    Genetically engineered mesenchymal stem cells as a nitric oxide reservoir for acute kidney injury therapy

    Haoyan Huang, Meng Qian ... Zongjin Li
    Engineered mesenchymal stem cells (MSCs) could produce mutant β-galactosidase and trigger nitric oxide (NO) release when the NO prodrug is systemically administered, which can achieve NO release in a precise spatiotemporal manner and augment the therapeutic efficiency of MSCs.

    Reciprocal interaction between mesenchymal stem cells and transit amplifying cells regulates tissue homeostasis

    Junjun Jing, Jifan Feng ... Yang Chai
    The molecular regulatory mechanisms that control the interaction between mesenchymal stem cells and transit amplifying cells to maintain tissue homeostasis.

    The neural crest is a source of mesenchymal stem cells with specialized hematopoietic stem cell niche function

    Joan Isern, Andrés García-García ... Simón Méndez-Ferrer
    Developing long bones contain distinct mesenchymal stem-cell populations derived from mesoderm and neural crest, which have specialized functions in skeleton formation and the establishment of the hematopoietic stem-cell niche, respectively.

    ATF4 licenses C/EBPβ activity in human mesenchymal stem cells primed for adipogenesis

    Daniel M Cohen, Kyoung-Jae Won ... David J Steger
    The transcription factor C/EBPβ binds to different DNA sequences depending on whether it binds to ATF4, which enables C/EBPβ to conduct diverse transcriptional programs during adipocyte differentiation by exploiting an expanded motif repertoire.

    PROP1 triggers epithelial-mesenchymal transition-like process in pituitary stem cells

    María Inés Pérez Millán, Michelle L Brinkmeier ... Sally A Camper
    The transcription factor PROP1 controls a genetic network that drives pituitary stem cells to undergo an epithelial-to-mesenchymal-like transition and differentiate.

    Mesenchymal stem cell suppresses the efficacy of CAR-T toward killing lymphoma cells by modulating the microenvironment through stanniocalcin-1

    Rui Zhang, Qingxi Liu ... Wenjian Ma
    The stanniocalcin-1-dependent immunosuppressive roles of mesenchymal stem cell on chimeric antigen receptor modified T cell therapy.

    Activation of hedgehog signaling in mesenchymal stem cells induces cartilage and bone tumor formation via Wnt/β-Catenin

    Qi Deng, Ping Li ... Baojie Li
    Cartilage and bone tumors arise from chondrocyte or osteoblast progenitors but not differentiated cells or multipotent mesenchymal stem cells (MSCs) via the IHH-Wnt/β-Catenin pathway.

    Cell circuits between leukemic cells and mesenchymal stem cells block lymphopoiesis by activating lymphotoxin beta receptor signaling

    Xing Feng, Ruifeng Sun ... Joao Pedro Pereira
    Acute lymphoblastic and myeloblastic leukemias activate lymphotoxin beta receptor in mesenchymal stem cells in the bone marrow to turn off interleukin-7 production and lymphopoiesis and gain competitive advantage.

    Transcriptional profiling of Hutchinson-Gilford Progeria syndrome fibroblasts reveals deficits in mesenchymal stem cell commitment to differentiation related to early events in endochondral ossification

    Rebeca San Martin, Priyojit Das ... Rachel Patton McCord
    Age-stratified comparisons of gene expression in progeria patient fibroblasts reveals disruption of mesenchymal lineage pathways and points to a deficit in chondrogenic commitment in early development and a depletion of the mesenchymal lineage stem cell pool.

    PLZF targets developmental enhancers for activation during osteogenic differentiation of human mesenchymal stem cells

    Shuchi Agrawal Singh, Mads Lerdrup ... Klaus Hansen
    A key transcription-factor for osteogenic differentiation, PLZF, acts as a transcriptional activator by binding to active developmental enhancers and facilitates mediator recruitment, but is not involved in enhancer looping.
