Embryology of the hair follicle
Early Human Development, 1991A study of hair follicle development has enabled us to differentiate four stages by relating them to corresponding gestation ages. Stage I of the hair bud is characterized by an epiblastic proliferation penetrating the subjacent mesenchyma at the extremity of which mesenchymal cells accumulate.

Reproduction in Domestic Animals, 2008
ContentsThe mare provides a unique experimental model for studying follicle development in monovular species. Development of antral follicles in horses is characterized by the periodic growth of follicular waves which often involve the selection of a single dominant follicle.

Follicle selection occurs throughout an adult female's reproductive life, with selected, dominant follicle(s) developing to the preovulatory stage whereas the remaining, subordinate follicles within the growing cohort instead undergo atresia and die. To date, most research into follicle dominance has concentrated on its endocrine regulation, although ...

Lateralization of Ovarian Follicles
Gynecologic and Obstetric Investigation, 2014<b><i>Background/Aim:</i></b> To evaluate a possible lateralization of antral follicle count (AFC) based on the finding that endometriosis, if present, is more commonly found in the left hemipelvis. <b><i>Methods:</i></b> We evaluated the records of 6,617 baseline ultrasounds conducted at our Reproductive

Influence of the dominant follicle on oocytes from subordinate follicles
Theriogenology, 1999As the oocyte grows within the follicle, a number of factors influence its health and developmental competence. These factors include follicle size, day of estrous cycle, level of atresia and influence of other follicles such as the dominant follicle. Follicles were dissected from ovaries of synchronized dairy cows on four days during the estrous cycle,

Hair has many useful biologic functions, including protection from the elements and dispersion of sweat-gland products (e.g., pheromones). It also has psychosocial importance in our society, and patients with hair loss (alopecia) (Table 1) or excessive hair growth often suffer tremendously.

Melatonin and the hair follicle
Journal of Pineal Research, 2007Abstract:âMelatonin, the chief secretory product of the pineal gland, has long been known to modulate hair growth, pigmentation and/or molting in many species, presumably as a key neuroendocrine regulator that couples coat phenotype and function to photoperiodâdependent environmental and reproductive changes.

Hair follicle predetermination
Journal of Cell Science, 2001Recent genetic and molecular studies of hair follicle (HF) biology have provided substantial insight; however, the molecular data, including expression patterns, cannot be properly appreciated without an understanding of the basic cellular rearrangements and interactions that underpin HF cyclic transformations.

The American Journal of Dermatopathology, 1984
A case of a 5-year-old child with a rare nevus of a hair follicle is reported. Histologically it was characterized by many hair follicles within the dermis at the same level of maturation. This nevus must be differentiated from other hamartomas of hair follicles and from Becker's nevus.

Estrogen actions on follicle formation and early follicle development.
Biology of reproduction, 2004Estradiol-17beta (E(2)) affects late follicular development, whereas primordial follicle differentiation and early activation are believed to be independent of E(2). To test this hypothesis we compared numbers of primordial and primary follicles in wild-type and E(2)-deficient, aromatase knockout (ArKO) mice, and the immunohistochemical staining or ...
