Growth of feathers cultivated <i>in vitro</i> for 11 days.

Abstract

The size (in mm) of 8 truncated feathers (4 from the neck and 4 from the thigh) inserted in their FF was measured after 3, 5, 7, and 11 days in culture. Note that each feather was shortened above the skin level before the dissection process. (A) Growth kinetic of individual feathers. Only the gain of growth over time is shown. Except for two feathers from the neck, all feathers weakly grew in length. (B). Total growth by origin (neck or thigh) over 11 days of cultivation.</p
