1. 21. Derivation, propagation and differentiation of human stem and progenitor cells

   Författare :Mathilda Zetterström Axell; Göteborgs universitet; []
   Nyckelord :Human embryonic stem cells; neural progenitor cells; stem cells; differentiation; propagation; migration; cell culturing; rostral migratory stream; electrospun scaffolds;

   Sammanfattning : Neuronal loss is a common feature of many neurological disorders, including stroke, Parkinson’s disease, Alzheimer’s disease and traumatic brain injury. Human embryonic stem cells (hESCs) and hESC-derived neural progenitors (NPs) may provide a number of new ways for studying and treating diseases and injuries in the brain. LÄS MER

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. Genetic Sex Differences in Early Human Neuronal Development : An Investigation in Embryo Tissue and Embryonic Stem Cells

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sex chromosome; gametolog; x y homolog; male; female; sex differences; sex bias; embryonic stem cells; neurodevelopment; neuronal differentiation; neural stem cells; genetics; neurodevelopmental disorders; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi; Neuroscience; Neurovetenskap; Medicinsk genetik; Medical Genetics;

   Sammanfattning : Sex differences in the human body affect many different organs and tissues, some of them have an effect on the human brain and its development. In the developing nervous system, sex differences can bias the number or functionality of neurons, glial cells or synapses. As a result, neural networks might develop with a sex-specific bias.

5. 24. 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.

7. 25. Adult Stem Cell Plasticity, Hype or Hope?

   Författare :Jalal Taneera; diabetes och endokrinologi Genomik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; pancreatic beta cell ; stem cell ; plasticity ; Medicin människa och djur ;

   Sammanfattning : Several studies have reported that bone marrow (BM)-derived stem cells have the capacity to give rise to cells of different type of tissue; an ability termed stem cell plasticity or transdifferentiation. Controversies exist as to how frequent this phenomenon is, or if it may be explained by alternative mechanisms. LÄS MER
