Mechano-regulation of the co-transcriptional effectors Yap and Taz in mesenchymal stem cells (MSC) in in vivo-like 3D systems


Much research in stem cell and developmental biology relies upon culturing cells on 2D surfaces. Indeed, the recent advance that Yap/Taz are mechano-regulators of the Hippo pathway was carried out in 2D culture systems. However, cell behaviour in 2D varies from that in the 3D in vivo environment. To understand stem cell behaviour and develop regenerative therapies, we need to observe cells in 3D. This ambitious project aims to evaluate how mechano-regulation of the co-transcriptional effectors Yap/Taz is controlled in vivo-like 3D systems. Ultimately, manipulation of these signals in defined 3D systems will enable us to effectively direct MSC differentiation.
