Radial Glial Fibers Promote Neuronal Migration and Functional Recovery after Neonatal Brain Injury.
2018
Radial glia (RG) are embryonic neural stem cells (NSCs) that produce neuroblasts and provide fibers that act as a scaffold for neuroblast migration during embryonic development. Although they normally disappear soon after birth, here we found that RG fibers can persist in injured neonatal mouse brains and act as a scaffold for postnatal ventricular-subventricular zone (V-SVZ)-derived neuroblasts that migrate to the lesion site. This injury-induced maintenance of RG fibers has a limited time window during post-natal development and promotes directional saltatory movement of neuroblasts via N-cadherin-mediated cell-cell contacts that promote RhoA activation. Transplanting an N-cadherin-contai…
Vitamin A Deficiency and the Lung.
2018
Vitamin A (all-trans-retinol) is a fat-soluble micronutrient which together with its natural derivatives and synthetic analogues constitutes the group of retinoids. They are involved in a wide range of physiological processes such as embryonic development, vision, immunity and cellular differentiation and proliferation. Retinoic acid (RA) is the main active form of vitamin A and multiple genes respond to RA signalling through transcriptional and non-transcriptional mechanisms. Vitamin A deficiency (VAD) is a remarkable public health problem. An adequate vitamin A intake is required in early lung development, alveolar formation, tissue maintenance and regeneration. In fact, chronic VAD has b…
Estudio de la quiescencia y activación de las células madre neurales adultas por uniones adherentes: papel de la N-cadherina.
2017
El descubrimiento de poblaciones de células madre en el cerebro adulto (NSCs) de los mamíferos ha cambiado nuestra visión del sistema nervioso, añadiendo el concepto de plasticidad celular al de plasticidad neural. El conocimiento detallado de los mecanismos que permiten a las NSCs mantenerse indiferenciadas, dividirse de manera asimétrica para auto-perpetuarse mientras generan progenie diferenciada, y activarse para proliferar contribuyendo así a la renovación de ciertas poblaciones de neuronas durante toda la vida se ha convertido en un campo de investigación en continuo avance. El desarrollo de técnicas que permiten la posibilidad de expandir las NSCs in vitro y de estudiarlas en su micr…
