Reasons why the pediatrician should participate in social media are studied, the differences between both types of social networks (vertical or scientific versus generalists) and how to estimate the likely audience in order to optimize the visibility efforts of pediatric professionals in both types, when networking. Some best practices in both categories are...

  8. Differentiation of mesenchymal stem cells for cartilage tissue engineering: Individual and synergetic effects of three-dimensional environment and mechanical loading

    Panadero Pérez, Juan Alberto; Lanceros-Méndez, S.; Gómez Ribelles, José Luís
    [EN] The importance of biomechanical cues in chondrogenesis is well known. This paper reviews the existing literature on the effect of mechanical stimulation on chondrogenic differentiation of mesenchymal stem cells in order to regenerate hyaline cartilage. Contradictory results found with respect to the effect of different modes of external loading can be explained by the different properties of the scaffolding system that holds the cells, which determine cell adhesion and morphology and spatial distribution of cells, as well as the stress transmission to the cells. Thus, this review seeks to provide an insight into the interplay between external loading program...
