    Hepatocyte Growth Factor-mediated satellite cells niche perturbation promotes development of distinct sarcoma subtypes

    Deborah Morena et al.
    The functional relevance of stem cell niche perturbation in sarcomagenesis is defined and the mouse model presented provides a rationale for the use of combination therapy for the treatment of genetically heterogeneous sarcomas.

    Reduced matrix rigidity promotes neonatal cardiomyocyte dedifferentiation, proliferation and clonal expansion

    Yfat Yahalom-Ronen et al.
    Compliant matrix provides a permissive micoenvironment for cardiomyocyte dedifferentiation, cell division and expansion, and thus may open a new avenue towards cardiac regeneration.

    Macrophages promote endothelial-to-mesenchymal transition via MT1-MMP/TGFβ1 after myocardial infarction

    Laura Alonso-Herranz et al.
    Macrophage production of MT1-MMP upon MI contributes to adverse cardiac remodeling and worsened function by promoting EndMT via TGFB, suggesting MT1-MMP inhibition as a therapeutic option for patients with MI.

    Increasing heart vascularisation after myocardial infarction using brain natriuretic peptide stimulation of endothelial and WT1+ epicardial cells

    Na Li et al.
    Brain natriuretic peptide supplementation can increase cardiac neovascularization in infarcted hearts by stimulating endogenous endothelial cell proliferation and proliferation of precursor cells, which will differentiate into endothelial cells.

    A new view of transcriptome complexity and regulation through the lens of local splicing variations

    Jorge Vaquero-Garcia et al.
    New methods reveal that complex local splicing variations are more prevalent in animals than previously appreciated, and demonstrate that local splicing variations are relevant for studies of development, gene regulation and neurodegenerative diseases.
