Fig. 3. Optical projection tomography mapping of D-V clone expansion domains. Three-dimensional representations and virtual sections of ventral (A-G) and dorsal (H,I) clones in E14.5 mouse limbs. (A,F) Lateral and oblique views, respectively, of a ventral clone. (B) Ventral view of the same limb. Lines C'-E' indicate the planes of the virtual sections in C-E, respectively. (G) The three-dimensional clone domain in isolation. (H,I) Lateral and oblique views, respectively, of a dorsal clone.
