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.

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,

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 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.

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 ...

Zentralblatt fur Gynakologie, 1984
A review is given of the present knowledge of the development of follicles and oocytes, especially in the human. The first report deals with the course of development of follicles from the beginning in the fetal ovary to the mature Graafian follicle in the adult women.

This chapter presents a very succinct overview of the cyclic biology of the hair follicle as it transitions from the quiescent telogen stage to the anagen stage in which hairs are actively produced before regressing through the catagen stage to telogen.

The ovarian follicle and fertility
The Journal of Steroid Biochemistry and Molecular Biology, 1991The precise roles of follicle stimulating hormone (FSH) and luteinizing hormone (LH) in the control of preovulatory follicle growth has been re-examined. Suppression of both pulsatile LH secretion and FSH or specific suppression of FSH results in an inhibition of preovulatory follicle growth beyond 2.5 mm dia.
