Insight Into Neural Stem Cells Has Implications For Designing Therapies
...ells. In theory you could activate these genes in embryonic
stem cells in the culture dish to try to create the desired type of neuron". The Alvarez-Buylla lab has identified neural stem cells in the adult human brain, but it is not known if these cells are heterogeneous. If human brains show a similar regi...
Cocaine Exposure can Alter Neuronal Development in Zebrafish

expression of genes regulating growth, neurotransmission and circadian system. Moreover, we found that the effects of the cocaine exposure were dependent on time of exposure, being more robust in the day, and were blocked or attenuated by the princ...

...n mammalian models. When dmPGE2 was added to mouse embryonic
stem cells in the lab, production of blood stem cells increased. In mice that underwent bone marrow transplant, treatment with dmPGE2 led to enhanced blood-stem-cell formation, and the stem cells remained present in the marrow more than six months af...
