  2. 1. Sox proteins and neurogenesis

    Author : Magnus Sandberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The primordium of the central nervous system is specified in a process called neural induction at which point the ectoderm is subdivided into the epidermal ectoderm and the neural plate. With time the neural plate will thicken, fold and form the neural tube. READ MORE

  4. 2. Neural stam cells, TLX, and Neuroblastoma

    Author : Ravi Kanth Rao Saini; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuroblastoma; TLX; Neural Stem Cells; Dedifferentiation; DISC-1; DNA-PKcs;

    Abstract : Neuroblastoma (NB) is one of the most commonly diagnosed extracranial tumors in children below five years of age. Moreover, NB accounts for almost 12-15% of all childhood cancer related fatalities. To date, the origin of NB has been linked to the neural crest derived sympathoadrenal progenitor cells. READ MORE

  5. 3. Early development of the olfactory placode and early rostrocaudal patterning of the caudal neural tube

    Author : Esther Maier; Lena Gunhaga; Fernando Giraldez; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; olfactory placode; caudal neural tube; Wnt; FGF; RA; BMP; Notch; patterning; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The development of the nervous system is a complex process. Cell divisions, cell differentiation and signalling interactions must be tightly regulated. To comprehend the mature nervous system, we have to understand its assembly during development. READ MORE

  6. 4. Regional control of cell fate determination and neurogenesis in the developing CNS

    Author : Ulrika Marklund; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The development of a functional central nervous system relies on the generation of distinct neuronal subtypes in a spatially and temporally defined order. The spatial organisation is achieved at early developmental time points when neural progenitor cells encounter fields of secreted morphogenic signalling molecules along the anterioposterior and dorsoventral axes of the embryo.

  7. 5. Neural stem cells and their contribution to neurogenesis in the adult mammalian brain

    Author : Stefan Momma; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : For a long time it was believed that neurogenesis in the mammalian central nervous system was restricted to the embryonic and early postnatal period. Almost four decades ago Altman and colleagues challenged this notion, but it took more than thirty years before new studies with refined methods convincingly demonstrated neurogenesis in the adult mammalian brain, including the adult monkey and human brain.
