Data Supplement

Files in this Data Supplement:

• Video 1 (MOV, 1.02 Mb)
  - Migration of GFP+ lymphocytes in mouse ear pinna in the absence of an applied electric field. The 3D images were depth coded so the depth of the cells (0-90um) is represented by colors (from blue to red).
• Video 2 (MOV, 1.1 Mb)
  - Migration of GFP+ lymphocytes in mouse ear pinna in an applied electric field (2.5V across ~5mm in the ear tissue with the cathode on the left). The 3D images were depth coded so the depth of the cells (0-90um) is represented by colors (from blue to red).
