HISTOCHEMICAL STUDY ON GLYCOGEN METABOLISM IN HAIR FOLLICLES

Histochemical study of follicles in the senescent porcine pituitary gland.

Follicles displaying a positive periodic acid-Schiff reaction to a colloid substance in the anterior pituitary gland have been observed in many vertebrates, including humans. It is also known that these follicles greatly increase in number and size with age. We therefore performed histochemical analysis of these colloid follicles in the senescent porcine pituitary gland in order to clarify thei...

Temporary hair removal by low fluence photoepilation: histological study on biopsies and cultured human hair follicles.

BACKGROUND AND OBJECTIVES We have recently shown that repeated low fluence photoepilation (LFP) with intense pulsed light (IPL) leads to effective hair removal, which is fully reversible. Contrary to permanent hair removal treatments, LFP does not induce severe damage to the hair follicle. The purpose of the current study is to investigate the impact of LFP on the structure and the physiology o...

On Artifacts Appearing in the Histochemical Fixation of Glycogen

1. Fixation artifacts associated with glycogen translocation are prevalent in tissues of parenchymatous type and scarce or non-existent in tissues of loose type. 2. Liver tissue treated with M/3 NaOH solution before fixation did not show an uneven distribution of glycogen. This was interpreted as indicating that the liver, a tissue of parenchymatous type, was changed, so to speak, into a loose ...

Histochemical demonstration of glycogen synthesis in vitro.

Immunohistochemical study of hair follicle stem cells in regenerated hair follicles induced by Wnt10b

The regulation of the periodic regeneration of hair follicles is complicated. Although Wnt10b has been reported to induce hair follicle regeneration, the characteristics of induced hair follicles, especially the target cells of Wnt10b, have not yet been clearly elucidated. Thus, we systematically evaluated the expression and proliferation patterns of Wnt10b-induced hair follicles. We found that...
