Gumi-Audenis, Berta, Costa, Luca, Redondo-Morata, Lorena, Milhiet, Pierre-Emmanuel, Sanz, Fausto, Felici, Roberto, Giannotti, Marina Ines, Carla, Francesco, (2018). In-plane molecular organization of hydrated single lipid bilayers: DPPC:cholesterol Nanoscale 10, 87-92

Understanding the physical properties of the cholesterol-phospholipid systems is essential to get a better knowledge on the function of each membrane constituent. We present a novel, simple and user-friendly setup that allows for straightforward grazing incidence X-rays diffraction characterization of hydrated individual supported lipid bilayers. This configuration minimizes the scattering from the liquid and allows the detection of the extremely weak diffracted signal of the membrane, enabling the differentiation of coexisting domains in DPPC:cholesterol single bilayers.


Alcaraz, J., Otero, J., Jorba, I., Navajas, D., (2018). Bidirectional mechanobiology between cells and their local extracellular matrix probed by atomic force microscopy Seminars in Cell and Developmental Biology 73, 71-81

There is growing recognition that the mechanical interactions between cells and their local extracellular matrix (ECM) are central regulators of tissue development, homeostasis, repair and disease progression. The unique ability of atomic force microscopy (AFM) to probe quantitatively mechanical properties and forces at the nanometer or micrometer scales in all kinds of biological samples has been instrumental in the recent advances in cell and tissue mechanics. In this review we illustrate how AFM has provided important insights on our current understanding of the mechanobiology of cells, ECM and cell-ECM bidirectional interactions, particularly in the context of soft acinar tissues like the mammary gland or pulmonary tissue. AFM measurements have revealed that intrinsic cell micromechanics is cell-type specific, and have underscored the prominent role of

P., (2018). Chronic lower-dose relaxin administration protects from arrhythmia in experimental myocardial infarction due to anti-inflammatory and anti-fibrotic properties International Journal of Cardiology 250, 21-28

Background: The peptide hormone relaxin-2 (RLX) exerts beneficial effects during myocardial ischemia, but functional data on lower-dose RLX in myocardial infarction (MI) is lacking. Therefore, we investigated the impact of 75

Garreta, E., González, F., Montserrat, N., (2018). Studying kidney disease using tissue and genome engineering in human pluripotent stem cells Nephron 138, 48-59

Kidney morphogenesis and patterning have been extensively studied in animal models such as the mouse and zebrafish. These seminal studies have been key to define the molecular mechanisms underlying this complex multistep process. Based on this knowledge, the last 3 years have witnessed the development of a cohort of protocols allowing efficient differentiation of human pluripotent stem cells (hPSCs) towards defined kidney progenitor populations using two-dimensional (2D) culture systems or through generating organoids. Kidney organoids are three-dimensional (3D) kidney-like tissues, which are able to partially recapitulate kidney structure and function in vitro. The current possibility to combine state-of-the art tissue engineering with clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated systems 9 (Cas9)-mediated genome engineering provides an unprecedented opportunity for studying kidney disease with hPSCs. Recently, hPSCs with genetic mutations introduced through CRISPR/Cas9-mediated genome engineering have shown to produce kidney organoids able to recapitulate phenotypes of polycystic kidney disease and glomerulopathies. This mini review provides an overview of the most recent advances in differentiation of hPSCs into kidney lineages, and the latest implementation of the CRISPR/Cas9 technology in the organoid setting, as promising platforms to study human kidney development and disease.
