Musashi1, a neural RNA-binding protein, plays an important role in regulating cell differentiation in precursor cells. Musashi-1 (Msi-1) has been shown to increase the accumulation of tau isoforms in intracellular inclusions in dementia and Parkinson's. The presence of Msi-1 in a significant percentage of neurons containing cytoplasmic inclusions in 2 other neurodegenerative diseases Alzheimer's disease and Pick disease suggests that it may play a role in the pathogenesis of these neurodegenerative disorders.

Musashi1 has also been detected in human tumor tissues such as gliomas and melanomas, suggesting its involvement in cancer development. Msi-1 also appears to play be an vital role in the development of several types of carcinoma such as human hepatoma, and may be a useful molecular marker for tumor detection.

Images: Immunostaining of  hNP1 Progenitors before and after differentiation. The culture was highly homogenous with neural rosettes. (A) Neural rosettes (white arrows, bright field) from WA09 cells. A similar result also obtained with BG02 cell line. (B) Shown here, a neural rosette stained with Nestin (NES) (green) antibody. Propagated Neural progenitors showed expression of marker genes, NES (C) and Musashi 1 (D) but not SOX2 (E). Further differentiation produced neurons (Tuj1) (F), astrocytes (GFAP) (G) and oligodendrocytes (myelin basic protein)(H) (lower panel). DAPI (blue) was used for staining the nuclei (scale bar for (A) through (E) is 100 mm and for the remaining figures 10 mm).
