Movie A: 3D reconstruction of the follicle shown in Figure 6A of Kopan et al., "Genetic mosaic analysis reveals that the bulb region of anagen hair follicles contains several active multipotent stem cells".

Movie B: 3D reconstruction of the follicle shown in Figure 6B of Kopan et al., "Genetic mosaic analysis reveals that the bulb region of anagen hair follicles contains several active multipotent stem cells".

Movie C: 3D reconstruction of the follicle shown in Figure 6C of Kopan et al., "Genetic mosaic analysis reveals that the bulb region of anagen hair follicles contains several active multipotent stem cells".

Movie D: 3D reconstruction of the same follicle shown in Movie C except that the LacZ+ clone (blue), the melanin granules (green), and the LacZ- clone (red) are shown sequentially.

Movie E: Movement of GFP cells from the bulb up the can be seen in these loop of static images. Cloistered GFP clones in a representative whisker, cultured for 5 d, were photographed from the same vantage point on successive days  UV epi-illumination. GIF images were collected into a movie loop and transition frames were added with GIFBuilder. the bulb is to the left, the bulge to the right of the image.
