The hypothalamus is a key homeostatic brain region and the primary effector of neuroendocrine signaling. Recent studies show that early embryonic developmental disruption of this region can lead to neuroendocrine conditions later in life, suggesting that hypothalamic progenitors might be sensitive to exogenous challenges. To study the behavior of hypothalamic neural progenitors, we developed a novel dissection methodology to isolate murine hypothalamic neural stem and progenitor cells at the early timepoint of embryonic day (E) 12.5, which coincides with peak hypothalamic neurogenesis. Additionally, we established and optimized a culturing protocol to maintain multipotent hypothalamic neurospheres that are capable of sustained proliferation or differentiation into neurons, oligodendrocytes, and astrocytes. We characterized media requirements, appropriate cell seeding density, and the role of growth factors and sonic hedgehog (Shh) supplementation. Finally, we validated the use of fluorescence activated cell sorting of either Sox2GFPKI or Nkx2.1GFPKI transgenic mice as an alternate cellular isolation approach to enable enriched selection of hypothalamic progenitors for growth into neurospheres. Combined, we present a new technique that yields reliable culturing of hypothalamic neural stem and progenitor cells that can be used to study hypothalamic development in a controlled environment.

A replication-defective strain of Murine leukemia virus (LEUKEMIA VIRUS, MURINE) capable of transforming lymphoid cells and producing a rapidly progressing lymphoid leukemia after superinfection with FRIEND MURINE LEUKEMIA VIRUS; MOLONEY MURINE LEUKEMIA VIRUS; or RAUSCHER VIRUS.
A replication-defective murine sarcoma virus (SARCOMA VIRUSES, MURINE) capable of transforming mouse lymphoid cells and producing erythroid leukemia after superinfection with murine leukemia viruses (LEUKEMIA VIRUS, MURINE). It has also been found to transform cultured human fibroblasts, rat liver epithelial cells, and rat adrenocortical cells.
A group of replication-defective viruses, in the genus GAMMARETROVIRUS, which are capable of transforming cells, but which replicate and produce tumors only in the presence of Murine leukemia viruses (LEUKEMIA VIRUS, MURINE).
