    • Aromatase activity of human mesenchymal stem cells is stimulated by early differentiation, vitamin D and leptin 
      Pino, Ana María; Rodríguez, Juan Manuel; Ríos, Susana; Astudillo, Pablo; Leiva, Laura; Seitz, Germán; Fernández Gálvez, Mireya; Rodríguez, J. Pablo (SOC ENDOCRINOLOGY, 2006-12)
      Human mesenchymal stem cells (hMSCs) are multipotent cells present in bone marrow, which differentiate into osteoblasts and adipocytes, among other lineages. Oestrogens play a critical role in bone metabolism; its action ...
    • Collagenase-like activity associated to the leukemic WEHI-3B cell line 
      Fernández Gálvez, Mireya; Martínez Winkler, Jorge; Minguell Uribe, José (1990)
      The leukemic cell line, WEHI-3B presents a latent collagenase-like activity which is activated after trypsin treatment. The enzymatic activity is not released from cells and is specific for the degradation of interstitial ...
    • Concentration of Adipogenic and Proinflammatory Cytokines in the Bone Marrow Supernatant Fluid of Osteoporotic ... 
      Pino, Ana María; Ríos, Susana; Astudillo, Pablo; Fernández Gálvez, Mireya; Figueroa, Paula; Seitz, Germán; Rodríguez, J. Pablo (2010-03)
      Osteoporosis is characterized by low bone mass, microarchitectural deterioration of bone tissue leading to increased bone fragility, and a resulting susceptibility to fractures. Distinctive environmental bone marrow ...
    • Cryopreservation of rainbow trout (Oncorhynchus mykiss) spermatozoa using programmable freezing 
      Conget Molina, Paulette; Fernández Gálvez, Mireya; Herrera, Guillermo; Minguell Uribe, José (Elsevier B.V., 1996)
      In an attempt to establish a protocol for the cryopreservation of the spermatozoa of the rainbow trout (Oncorhynchus mykiss), we studied the effect of various cryoprotective agents (CA) in spermatozoa motility and viability, ...
    • Evidence for cooperative effects in human liver arginase 
      Carvajal Baeza, Nelson; Acoria García, Marina; Rodríguez Vives, Juan Pablo; Fernández Gálvez, Mireya; Martínez Winkler, Jorge (1982)
      The reaction kinetics of human liver arginase (l-arginine amidinohydrolase, EC 3.5.3.1) in terms of arginine concentration is strikingly altered by varying the pH. Lowering the pH from the optimum (9.5) toward a more ...
