Prominin-1-expressing cerebellar stem cells reside in the prospective white matter during the first 3 weeks of postnatal life. Their proliferation is tightly controlled by the sonic hedgehog pathway supported by Purkinje cells17. These stem cells/progenitors contribute to later-born GABAergic interneurons called basket cells and stellate cells. These interneurons reside in the molecular layer, where they synapse onto Purkinje cells and sculpt PC topography and function via GABAergic inhibition<sup...

The cerebellum has been long recognized as a major neuronal circuit coordinating voluntary movement1. It receives input from the wide swathes of the neuroaxis, which includes proprioceptive information from the periphery, so as to fine tune motor output&#160;and coordinate motion. More recently, it has also been implicated in regulating cognition and emotions by potentially using similar information processing networks2,3,4.
The adult cerebellum is composed of an outer cerebellar cortex and inner white matter. Interspersed within these structures are deep intracerebellar nuclei. Similar to the rest of the nervous system, the development of the cerebellum is driven by the proliferation of multipotent progenitor cells (stem cells) that migrate and differentiate to yield this well-organized structure. In early development (E10.5&#8211;E13.5), a ventricular stem niche around the developing fourth ventricle generates GABAergic neurons (i.e., Purkinje cells, Lugaro cells, Golgi cells) along with Bergmann glia5,6,7,8.
Later in development (postnatal week one), a second stem cell niche in the rhombic lip generates MATH1- and Nestin-expressing progenitors that give rise to excitatory granule neurons9,10,11,12. Recently a third stem cell niche has been described13. These cells express prominin-1 (also known as CD133), a membrane-spanning glycoprotein that defines a subset of stem cells in the intestine and hematopoietic systems14,15,16. In vivo fate mapping shows that these stem cells generate key molecular layer interneurons (i.e., basket cells and stellate cells), along with astrocytes, during the first three postnatal weeks. In the past, it has been difficult to study these cells in vitro because prior methods have required costly and time-consuming techniques (i.e., fluorescence-activated cell sorting [FACS]) that are dependent on prominin-1 staining12,13,17. This protocol describes an immunomagnetic-based method for the isolation of these stem cells that can then be readily cultured and differentiated.

purification of prominin-1+ stem cells from postnatal mouse cerebellum

Most cerebellar neurons arise from two embryonic stem niches: a rhombic lip niche, which generates all the cerebellar excitatory glutamatergic neurons, and a ventricular zone niche, which generates the inhibitory GABAergic Purkinje cells, which are neurons that constitute the deep cerebellar nuclei and Bergman glia. Recently, a third stem cell niche has been described that arises as a secondary germinal zone from the ventricular zone niche. The cells of this niche are defined by the cell surface marker prominin-1 and are localized to the developing white matter of the postnatal cerebellum. This niche accounts for the late born molecular layer GABAergic interneurons along with postnatally generated cerebellar astrocytes. In addition to their developmental role, this niche is gaining translational importance in regards to its involvement in neurodegeneration and tumorigenesis. The biology of these cells has been difficult to decipher because of a lack of efficient techniques for their purification. Demonstrated here are efficient methods to purify, culture, and differentiate these postnatal cerebellar stem cells.

Prominin-1-positive postnatal cerebellar stem cells formed neurospheres in neurosphere medium rich in growth factors (EGF and bFGF). These neurospheres were positive for prominin-1-staining, the marker used for isolation, and also as a stain for other stem cell markers such as Nestin and GFAP13 (Figure 1). The stem cell marker expression was maintained throughout culture and for up to at least eight passages20. Upon withdrawal of growth factors...
