Normal hair growth occurs in cycles, comprising (anagen), cessation (catagen) and rest (telogen). Upon aging, the initiation of anagen is significantly delayed, which results impaired regeneration. Hair regeneration driven by follicle stem cells (HFSCs). We show here that aged HFSCs present with a decrease canonical Wnt signaling shift towards non-canonical Wnt5a antagonizes signaling. Elevated...
A hairy kinase o get a hairy mouse, look to the Sgk3 kinase. So say Alonso et al. on page 559. The control of hair follicle growth has been an enigma for cell biologists. While growth factors such as EGF are known for their ability to stimulate proliferation in epithelial cells, EGF causes hair loss. In addition, the downstream signals that control hair growth are largely unknown. Now, an Akt r...
Hair regression and balding are distressing concerns for an increasing number of people due to changes in lifestyle and serious nutritional imbalances. Therapies for treatment of hair loss are needed. Among potential therapeutics, adenosine has been suggested as a potent regulator of hair growth. In this study, we investigated the effects of adeno...
BACKGROUND/AIM The lipopolysaccharide (LPS)-like compound derived from Pantoea agglomerans (immunopotentiator from Pantoea agglomerans 1 (IP-PA1)) has been used not only as dietary supplement or cosmetic for humans, but also by Japanese veterinarians as an anti-tumor, anti-allergy, "keep a fine coat of fur" and hair growth-promoting functional food for dogs and cats. In the present study, we fo...
Natural mutations in the LIPH gene were shown to be responsible for hair growth defects in humans and for the rex short hair phenotype in rabbits. In this species, we identified a single nucleotide deletion in LIPH (1362delA) introducing a stop codon in the C-terminal region of the protein. We investigated the expression of LIPH between normal coat and rex rabbits during critical fetal stages o...
The rough coat (rc) spontaneous mutation causes sebaceous gland (SG) hypertrophy, hair loss, and extracutaneous abnormalities including growth retardation. The rc mice have a missense mutation in the predicted Ig protein Myelin Protein Zero-Like 3 (Mpzl3). In this study, we generated Mpzl3 knockout mice to determine its functions in the skin. Homozygous Mpzl3 knockout mice showed unkempt and gr...
BACKGROUND Androgenetic alopecia (AGA) is a common problem in men of all ages, affecting approximately 50% at 50 years of age. The underlying cause is an androgen-dependent miniaturization of genetically predetermined hair follicles. Here, the hair organ culture model was used to investigate the effects of testosterone and caffeine; the latter being a promising candidate for hair growth stimula...
Melanocytes characterized by their tyrosinase activity, melanosomes and dendrites locate in the basal layer of epidermis and hair bulb in the skin of mice. Melanocytes differentiate from undifferentiated melanoblasts derived from embryonic neural crest. Melanocyte-stimulating hormone plays an important role in the regulation of the differentiation of mouse melanocytes in the epidermis and hair ...
Moringa olifera lamk and Nephelium lappaceaum L leaves are empirically widely used to stimulate hair growth. The purpose of this research is combine the kelor leaf extract rambutan formulated in tonic. tonic preparations made were evaluated by performing a physical test preparation knowing best concentration on rabbit orepared 3 formulations with ratio exract (1:3 , 1:1 3:1)% w/v. positive cont...
