Neogenesis of Wool Follicles

Abstract

The possible formation of new wool follicles in healing experimental wounds was studied in one adult sheep and in three new-born lambs. True neogenesis 'was considered to have occurred in the epithelium covering the scars, though relatively few follicles were observed. Attempts to prevent contraction of the scar tissue, so that formation of new follicles might be encouraged, were unsuccessful. This failure is possibly the reason for the paucity of new follicles. Several early-stage follicles, seen in association with the neck region of existing follicles surrounding the wound margin, were also considered to be newly formed.
