 Neural precursor cells in the human SVZ are known to yield offspring which can then produce glial cells or even migrate and form new neurons in specific areas such as the mammalian olfactory bulb.Although the exact chemical signaling pathways which regulate Neuropoiesis are still poorly understood, there have been some recent advances in this field.Hematopoiesis, the differentiation of stem cells in the bone marrow to form blood cells, is a comparatively well studied phenomenon, and the study of hematopoiesis has yielded some insight into the mechanisms of neuropoiesis.
