Determination of the Depth of Excision Using a Dermatome (Aesculap^®) to Export all Hair Follicle Bulbs from a Donor Site in the Dog

Abstract

The aim of the study was to determine the depth of excision using a dermatome to excise all hair follicle bulbs from the donor site. Partial-thickness skin samples of different depth, ranging from 0.4 to 1 mm, were excised using a dermatome (Aesculap) from the dorsal aspect of the trunk of the dog. Biopsies, using a 6-mm biopsy punch, were performed in the centre of each donor site and excised sample. They were processed routinely for histological examination and the aspect of the hair follicles was observed. Split-thickness skin grafts of >or=0.7 mm deep performed with a dermatome contain the entire hair follicle.

Time-course RNA-seq analysis reveals stage-specific and melatonin-triggered gene expression patterns during the hair follicle growth cycle in Capra hircus

“…The cashmere goat has two different fibrous hair structures: thick and coarse hairs forming the guard layer and soft hairs forming the ground cashmere. The cashmere comes from secondary hair follicles (SHFs) in the skin [1], and the coarse hair comes from primary hair follicles [2,3]. The cashmere obtained from goats is specially used for production of expansive textile products [4].…”

Skin transcriptome reveals the periodic changes in genes underlying cashmere (ground hair) follicle transition in cashmere goats

“…Inner Mongolian cashmere goats have two distinctly different fibrous hair structures, with thick, coarse guard hairs forming the outer layer and fine, soft ground hairs forming the cashmere underneath. The cashmere comes from secondary hair follicle structures in the skin [8], and the coarse hair comes from primary hair follicles [9,10]. Hair follicles, after shedding their old hair shafts, produce new hair shafts [11], thereby starting a new cycle of hair growth [12].…”
