1. 21. Stem cells : proliferation, differentiation, migration

   Författare :Anna Falk; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Embryonic stem cell; adult neural stem cells; proliferation; differentiation; migration;

   Sammanfattning : A stem cell is demanding and requires precise conditions to carry out its unique tasks. This includes proliferation as an undifferentiated stem cell, differentiation to more mature cell types, migration through tissue to its final destination, and functional integration into the cellular network.

3. 22. Roles of PDGF for Neural Stem Cells

   Författare :Mia Enarsson; Karin Nilsson; Bengt Westermark; Peter Eriksson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; CNS; stem cells; neuron; PDGF; proliferation; differentiation; ERK; microarray; transgenic mouse; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi;

   Sammanfattning : Stem cells are endowed with unique qualities: they can both self-renew and give rise to new mature cell types. Central nervous system (CNS) stem cells can give rise to neurons and glia. LÄS MER

4. 23. Regulation and functions of basic helix-loop-helix transcription factors in neuroblastoma cells

   Författare :Paula Persson; Institutionen för translationell medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; Id; Olf EBF; ubiquilin-1; HASH-1; bHLH; Neuroblastoma; neuronal differentiation; cancer; onkologi; cancerology; Cytologi;

   Sammanfattning : Neuroblastoma is a childhood tumor derived from primordial neural crest cells. The tumor cells exhibit a phenotype similar to that of developing neuroblasts, which indicates that the tumor arises due to perturbed differentiation of the sympathetic nervous system. LÄS MER

5. 24. bHLH transcription factors in differentiating neuroblastoma cells

   Författare :Anna Grynfeld; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bHLH; Neuroblastoma; HES-1; HASH-1; N-Myc; differentiation; Mad; Medicine human and vertebrates ; Medicin människa och djur ;

   Sammanfattning : Neuroblastoma is a tumor of the sympathetic nervous system, and arises during early childhood. The tumor is highly heterogeneous and evidence, such as expression of genes normally only expressed during embryonic and fetal stages, suggests that the tumor is of embryonic origin and that the tumor arises as a consequence of perturbed differentiation during the development of the sympathetic nervous system.

7. 25. Phenotypic Specification of Striatal Progenitors; Evidence for both cell-autonomous and environmental control as studied by transplantation into the adult and developing rodent brain

   Författare :Martin Olsson; Neurobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; striatal projection neurons; striatal development; somatostatin; parvalbumin; neuronal differentiation; neural transplantation; medial ganglionic eminence; lateral ganglionic eminence; forebrain dvelopment; cholinergic; embryonic; thyroid transcription fa; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

   Sammanfattning : The striatum is the major component of the ventral telencephalon and basal ganglia, involved in the processing of cortical information. The vast majority of the neuronal population in the striatum are striatal projection neurons, with connection to the globus pallidus and substantia nigra. LÄS MER
