Arthur C. Danto proposes a complex and controversial relationship between surface and deep interpretations in The Philosophical Disenfranchisement of Art (1986). We detail the analogy between understanding human actions and interpreting works of art that both develops a motivation for Danto's view and clarifies it. We object to the most plausible version of content dependency among surface and deep interpretations and in so doing, we also clarify the way in which an interpretation is constitutive of an artwork

Adipogenic Mesenchymal Stromal Cells from Bone Marrow and Their Hematopoietic Supportive Role: Towards Understanding the Permissive Marrow Microenvironment in Acute Myeloid Leukemia

International audiencePurpose The role of bone marrow-derived mesenchymal stem/stromal cells (MSCs) in creating a permissive microen-vironment that supports the emergence and progression of acute myeloid leukemia (AML) is not well established. We investigated the extent to which adipogenic differentiation in normal MSCs alters hematopoietic supportive capacity and we undertook an in-depth comparative study of human bone marrow MSCs derived from newly diagnosed AML patients and healthy donors, including an assessment of adipogenic differentiation capacity. Findings MSCs from healthy controls with partial induction of adipogenic differentiation, in comparison to MSCs undergoing partial osteogenic differentiation, expressed increased levels of hematopoietic factors and induced greater proliferation , decreased quiescence and reduced in vitro hematopoietic colony forming capacity of CD34 + hematopoietic stem and progenitor cells (HSPCs). Moreover, we observed that AML-derived MSCs had markedly increased adipogenic potential and delayed osteogenic differentiation, while maintaining normal morphology and viability. AML-derived MSCs, however, possessed reduced proliferative capacity and decreased frequency of subendothelial quiescent MSCs compared to controls. Conclusion Our results support the notion of a bone marrow microenvironment characterized by increased propensity toward adipogenesis in AML, which may negatively impact normal hematopoiesis. Larger confirmatory studies are needed to understand the impact of various clinical factors. Novel leukemia treatments aimed at normalizing bone marrow niches may enhance the competitive advantage of normal he-matopoietic progenitors over leukemia cells
