General description

In mammals, the Musashi family is important for cell fate determination, playing roles in maintenance of the stem-cell state, cellular differentiation, nuclear signaling and tumorigenesis. Musashi-1 (also known as Msi1), is selectivley expressed in neural progenitor cells, including neural stem cells. Outside the nervous system, Musashi-1 is a selective marker for intestinal stem or early lineage cells. Musashi-1 interacts with the Notch pathway during asymmetric cell division by binding the 3′ UTR of Numb. Numb is prevented from repressing Notch signaling when Musashi-1 is present.

Immunogen

GST-tagged recombinant protein corresponding to human Musashi-1.

Evolutionarily conserved RNA-binding protein Musashi1 (Msi1) can regulate developmentally relevant genes. Here we report the generation and characterization of a mouse model that allows inducible Msi1 overexpression in a temporal and tissue-specific manner. We show that ubiquitous Msi1 induction in

As for many lizards, the leopard gecko (Eublepharis macularius) can self-detach its tail to avoid predation and then regenerate a replacement. The replacement tail includes a regenerated spinal cord with a simple morphology: an ependymal layer surrounded by nerve tracts.
