Secondary damage to hair follicles in full thickness skin autografts

Archiv f�r Dermatologische Forschung, 1974
The hair root pattern in full-thickness skin autografts in guinea pigs was evaluated on the basis of findings in a total of 34 grafts. Between the 4th and 12th day after surgery the proportion of anagen hairs was found elevated and increasing in all cases.

DNA methylation and histone acetylation are involved in Wnt10b expression during the secondary hair follicle cycle in Angora rabbits

Journal of Animal Physiology and Animal Nutrition, 2021
AbstractSecondary hair follicles (SHFs) in the Angora rabbit exhibit classic cyclic hair development, but the multiple molecular signals involved in hair cycling are yet to be explored in detail. In the present study, we investigated the expression pattern, methylation and histone H3 acetylation status of Wnt10b, as a molecular signal participating in ...

Comparative proteomics reveals genetic mechanisms underlying secondary hair follicle development in fine wool sheep during the fetal stage

Journal of Proteomics, 2020
The aim of this study was to investigate the genetic mechanisms underlying wool production by characterizing the skin protein profile and determining the proteomic changes that occur as a consequence of development in wool-producing sheep using a label-free proteomics approach.

The reaction-diffusion (RD) theory of wool (hair) follicle initiation and development. II. Original secondary follicles

Australian Journal of Agricultural Research, 1995
In an accompanying paper it was shown that a spatial prepattern mechanism based on a biochemical reaction referred to as a reaction-diffusion (RD) system is able to account for many aspects of the initiation and development of primary (P) wool follicles. In this paper the same RD system is applied to the initiation and development of original secondary

Never too old to regenerate? Wound induced hair follicle neogenesis after secondary intention healing in a geriatric patient

Journal of Tissue Viability, 2018
Wound healing is a natural process to restore the structure and function of injured or diseased tissues. Repair of a skin wound usually leads to a scar while regeneration implies fully recovery of function and structure of the damaged tissue. Adult skin wound usually heals with scar while fetal skin heals scarless.

The cause of primary and secondary damage to hair follicles on full thickness skin autografts

Archiv f�r Dermatologische Forschung, 1974
Heat loss by radiation and conduction and oxygen release were measured on full thickness skin autografts in 46 guinea pigs on the seventh postoperative day. Using the same animals, the amount of hair on the graft was determined 3 months after surgery.

Conversion of methionine to cysteine by transulphuration in isolated anagen secondary hair follicles of the Angora goat

Proceedings of the British Society of Animal Science, 1998
Enzymes catalysing the conversion of methionine to cysteine via the transulphuration pathway are found in liver and kidney of sheep (Radcliffe and Eggan, 1974), but their presence has not been established in the hair follicle. The aims of this study were (a) to establish the presence of transulphuration and (b) to determine quantitatively the ...

Growth and viability of secondary hair follicles of the Angora goat cultured in vitro.

Journal of anatomy, 1993
The viability of isolated secondary anagen hair follicles from Angora goats was studied in an in vitro tissue culture system. Intact hair follicles were isolated from the dermal layer singly or in groups using watchmakers' forceps under a dissecting microscope following removal of both the epidermis at the basal layer and subcutaneous fat layers using ...

Effect of biotin on growth, viability and apparent DNA synthesis in cultured secondary hair follicles of the Angora goat

Proceedings of the British Society of Animal Science, 1998
Biotin is a water soluble vitamin which has a well proven function in corboxylation reactions in animal tissues. It is well documented that biotin deficiency in mammals causes pathological changes in the skin and its appendages such as desquamative dermatitis and alopecia.

In vitroFibre production and protein deposition in secondary hair follicles of the cashmere and angora goat

Proceedings of the British Society of Animal Production (1972), 1994
Hair fibre represents an important biological process to many feral and domesticated animals, both for environmental protection and as an aid to thermoregulation. Mohair which is the fine fibre produced by secondary hair follicles of the Angora goat grows essentially independent of season, with typical growth rates of 0.5-1 .0mm/day and annual yields ...
