| Figure 1: Culture 1; initial state of skin from
8 day chicks. Skin placed in Hank’s Balanced Salt Solution 1X, on
Transwell 3452 culture inserts (24mm diameter). Presence of feather placodes
is obvious along length of skin. (A) Note the dorsal-lateral differences
in development (highlighted by red arrow; D= dorsal, DL =dorsolateral).
(B) Close-up of placodes. Note the curvature of the feather placode patterning
(red arrows); probably a result of uneven positioning of the skin on the
culture dish. |
