Topographical analysis of the subependymal zone neurogenic niche
Falcão, Ana M.; Palha, Joana Almeida; Ferreira, Ana Catarina; Marques, Fernanda Cristina Gomes de Sousa; Sousa, Nuno; Sousa, João CarlosThe emerging model for the adult subependymal zone (SEZ) cell population indicates that neuronal diversity is not generated from a uniform pool of stem cells but rather from diverse and spatially confined stem cell populations. Hence, when analysing SEZ proliferation, the topography along the anterior-posterior and dorsal-ventral axes must be taken into account. However, to date, no studies have assessed SEZ pr...
The path from the choroid plexus to the subventricular zone: go with the flow!
Falcão, Ana M.; Marques, Fernanda; Novais, Ashley da Cruz; Sousa, Nuno; Palha, Joana Almeida; Sousa, João CarlosIn adult mammals, under physiological conditions, neurogenesis, the process of generating new functional neurons from precursor cells, occurs mainly in two brain areas: the subgranular zone in the dentate gyrus of the hippocampus, and the subventricular zone (SVZ) lining the walls of the brain lateral ventricles. Taking into account the location of the SVZ and the cytoarchitecture of this periventricular neural...
In vivo biodistribution of carboxymethylchitosan/poly(amidoamine) dendrimer nan...
Pereira, Vitor H.; Salgado, A. J.; Oliveira, Joaquim M.; Cerqueira, Susana R.; Frias, A. M.; Fraga, J. S.; Roque, Susana; Falcão, Ana M.Carboxymethylchitosan/poly(amidoamine) dendrimer nanoparticles (CMCht/PAMAM) have recently been proposed for intracellular drug delivery purposes. These are constituted by a PAMAM dendrimer core grafted with chains of CMCht. Previous reports have shown that these nanoparticles disclosed an improved cytotoxic profile when compared to traditional dendrimers. Following on these results the present study aims to as...
