    • Inhibiting stromal cell heparan sulfate synthesis improves stem cell mobilization and enables engraftment without cytotoxic conditioning 

      Saez, Borja; Ferraro, F.; Yusuf, Rushdia Zareen; Cook, Colleen M.; Yu, Vionnie Wing Chi; Pardo-Saganta, A.; Sykes, Stephen M.; Palchaudhuri, Rahul; Schajnovitz, Amir; Lotinun, S; Lymperi, Stefania; Mendez-Ferrer, Simon; del Toro, Raquel; Day, Robyn Rouviere; Vasic, Radovan; Acharya, Sanket Shyamkant; Baron, Roland; Lin, Charles P.; Yamaguchi, Yu; Wagers, Amy Jo; Scadden, David Thomas (American Society of Hematology, 2014)
      The glycosyltransferase gene, Ext1, is essential for heparan sulfate production. Induced deletion of Ext1 selectively in Mx1-expressing bone marrow (BM) stromal cells, a known population of skeletal stem/progenitor cells, ...
    • Myocardial Infarction Activates CCR2+ Hematopoietic Stem and Progenitor Cells 

      Dutta, Partha; Sager, Hendrik B; Stengel, Kristy R.; Naxerova, Kamila; Courties, Gabriel P; Saez, Borja; Silberstein, Lev; Heidt, Timo; Sebas, Matthew; Sun, Yuan; Wojtkiewicz, Gregory; Feruglio, Paolo Fumene; King, Kevin Robert; Baker, Joshua N.; van der Laan, Anja M.; Borodovsky, Anna; Fitzgerald, Kevin; Hulsmans, Maarten; Hoyer, Friedrich Felix; Iwamoto, Yoshiko; Vinegoni, Claudio; Brown, Dennis; Di Carli, Marcelo; Libby, Peter; Hiebert, Scott W.; Scadden, David Thomas; Swirski, Filip K.; Weissleder, Ralph; Nahrendorf, Matthias (Elsevier BV, 2015)
      Following myocardial infarction (MI), myeloid cells derived from the hematopoietic system drive a sharp increase in systemic leukocyte levels that correlates closely with mortality. The origin of these myeloid cells, and ...
    • SIRT1 Regulates Differentiation of Mesenchymal Stem Cells by Deacetylating β-Catenin 

      Simic, Petra; Zainabadi, Kayvan; Bell, Eric; Sykes, David Brian; Saez, Borja; Lotinun, Sutada; Baron, Roland; Scadden, David Thomas; Schipani, Ernestina; Guarente, Leonard (WILEY-VCH Verlag, 2013)
      Mesenchymal stem cells (MSCs) are multi-potent cells that can differentiate into osteoblasts, adipocytes, chondrocytes and myocytes. This potential declines with aging. We investigated whether the sirtuin SIRT1 had a ...
    • Specific bone cells produce DLL4 to generate thymus-seeding progenitors from bone marrow 

      Yu, Vionnie W.C.; Saez, Borja; Cook, Colleen; Lotinun, Sutada; Pardo-Saganta, Ana; Wang, Ying-Hua; Lymperi, Stefania; Ferraro, Francesca; Raaijmakers, Marc H.G.P.; Wu, Joy Y.; Zhou, Lan; Rajagopal, Jayaraj; Kronenberg, Henry M.; Baron, Roland; Scadden, David T. (The Rockefeller University Press, 2015)
      Production of the cells that ultimately populate the thymus to generate α/β T cells has been controversial, and their molecular drivers remain undefined. Here, we report that specific deletion of bone-producing osteocalcin ...
