Although adult mouse hematopoietic stem cells (HSCs) have been purified to near homogeneity, it remains impossible to achieve this with fetal HSCs. Adult HSC purity recently has been enhanced using the SLAM family receptors CD150, CD244, and CD48. These markers are expressed at different stages of the hematopoiesis hi…

The neuroscience community has witnessed a tremendous expansion of glia research. Glial cells are now on center stage with leading roles in the development, maturation, and physiology of brain circuits. Over the course of evolution, glia have highly diversified and include the radial glia, astroglia or astrocytes, mic…

BACKGROUND: Hematopoiesis is a complex developmental process controlled by a large number of factors that regulate stem cell renewal, lineage commitment and differentiation. Secreted proteins, including the hematopoietic growth factors, play critical roles in these processes and have important biological and clinical…

BACKGROUND: Fear conditioning is a form of learning essential for animal survival and used as a behavioral paradigm to study the mechanisms of learning and memory. In mammals, the amygdala plays a crucial role in fear conditioning. In teleost, the medial zone of the dorsal telencephalon (Dm) has been postulated to be…

Mutations in the gene encoding tau (MAPT) cause frontotemporal dementia spectrum disorders. A rare tau variant p.A152T was reported as a risk factor for frontotemporal dementia spectrum and Alzheimer's disease in an initial case-control study. Such findings need replication in an independent cohort. We analysed an ind…

Hematopoietic stem cells (HSCs) and endothelial progenitors arise from a common embryonic precursor. However, these populations diverge prior to the onset of definitive hematopoiesis, as HSCs become CD45+ and are thought to lose the expression of endothelial markers. After the onset of definitive hematopoiesis, CD144…

Animal models contribute greatly to our understanding of brain development and function as well as its dysfunction in neurological diseases. Epilepsy research is a very good example of how animal models can provide us with a mechanistic understanding of the genes, molecules, and pathophysiological processes involved i…

The zebrafish (Danio rerio) is one of the most promising new model organisms. The increasing popularity of this amazing small vertebrate is evident from the exponentially growing numbers of research articles, funded projects and new discoveries associated with the use of zebrafish for studying development, brain funct…
