In the November 7th edition of biobytes, Mailin Hamm and Wiebke Herzog

(University of Muenster, Muenster, Germany) describe how Semaphorin3d regulates

endothelial cell migration (Hamm et

al.), and Christopher Lengner (University of Pennsylvania, Philadelphia,

PA) explains how Msi proteins maintain a reserve population of intestinal stem cells

(Yousefi

et al.). Plus a round-up of other highlights from The Journal of

Cell Biology. The show was written and produced by Caitlin Sedwick and

Ben Short. Presented by Ben Short. See the associated papers in

JCB for details on the funding provided to support these
