which remained unchanged upon oligo-differentiation (Determine 6F), we suggest that their conversion into cells in a position to acquire an oligodendroglial destiny in the system of in vitro growth was Shhindependent

Also these differentiated `RSCs' confirmed expression of oligodendrocyte-specific markers at protein and RNA stages (information not shown). To verify that peripheral `RSC'-derived oligodendrocytes resemble oligodendrocytes at the molecular level, we…
