	hair biology - hair follicle structure
		The total number of hair follicles for an adult human is estimated at 5 million with 1 million on the head of which 100,000 alone cover the scalp.
		The hair follicle penetrates the dermal layer of the skin composed of fibroblast cells and collagen connective tissue interspersed with blood vessels, sweat glands and sensory nerves.
		When a hair follicle is not producing a fiber the DP cells lose much of their cytoplasm and become inactive.

	Antral Follicle Counts and IVF Stimulation Response
		Presumably, the number of antral follicles visible on ultrasound is indicative of the relative number of microscopic (and sound asleep) primordial follicles remaining in the ovary.
		Antral follicle counts are a good predictor of the number of mature follicles that we will be able to stimulate in the woman's ovaries when we administer the injectable FSH medications that are used for in vitro fertilization.
		At least in some women, the antral follicle count may be a good predictor of the number of eggs remaining in the ovaries, as well as the quality of those eggs.

	Can Egg Follicle Size Indicate Cow Fertility?
		As the follicle grows, the estrogen eventually reaches a threshold level that causes the cow to be in heat.
		Perry measured their ovulating follicles when they were induced to ovulate, but before artificial insemination.
		However, it appears that if the follicle is capable of ovulating naturally, it doesn't matter what size it is. A cow in standing estrus with an 11-mm follicle has the same chance of becoming pregnant and maintaining the pregnancy as a cow with a 16-mm follicle.

	follicle stimulating hormone (injectable)
		Follicle stimulating hormone is used to stimulate a follicle (egg) to develop and mature.
		Follicle stimulating hormone is also used to stimulate the development of multiple eggs for in vitro fertilization.
		Follicle stimulating hormone is in the FDA pregnancy category X. This means that follicle stimulating hormone is known to cause birth defects in an unborn baby (when used beyond the period of ovulation).

	Hair and Follicle Cloning a 2004 Update
		The follicles are then dissected to isolate a small ball of cells at the base of each follicle called the dermal papilla.
		A new hair follicle is made from epithelial cells, but the development and cycling of the follicle is determined by dermal papilla cells.
		It might be possible one day to cause new hair follicle formation by applying skin with a chemical signal that triggers the resident dermal cells to return to their embryogenic days, but such a treatment approach is not likely for a long time.

	The Ovarian Follicle 2
		Schroll down the page to follow the follicles during their maturation from primary follicles to secondary follicles and, finally, to the corpus luteum.
		The blue arrow follows the the ovarian follicles from their maturation (from primary follicles) to their eventual demise (as the corpus luteum).
		The corpus luteum is the enlarged remnant of the secondary (Graafian) follicle following ovulation (the release of the oocyte).

	The World of Hair - Hair Structure - Follicle - Hair Bulb
		A hair follicle is a tiny cup-shaped pit buried deep in the fat of the scalp.
		The temperature around the follicle is normal body temperature, and is not affected by cold or hot weather.

		The hair follicle comprises the dermal papilla which invaginates into the base of the follicle where rapidly dividing matrix cells are located (see Figure 1).
		Aromatase, present in the outer root sheath of the hair follicle, is another enzyme that plays an important function in androgenetic alopecia.

	Hair follicle stem cells contribute to wound healing
		Using an animal model, the researchers discovered that stem cells in the hair follicle are enlisted to help heal wounds in the skin.
		What remained a mystery was the exact nature of the origins of the new cells-specifically, what percentage stems from the deep follicle and what percentage from the epidermis near the wound.
		Cotsarelis' team found that adult stem cells from the lowest portion of the hair follicle, or "bulge," quickly ascend the follicle in response to wounding and ultimately comprise about 30 percent of the new cells in a wound when it first starts to heal.

		Keratosis pilaris is a condition in which the hair follicles become blocked with hair and dead cells from the outermost layer of skin (epidermis).
		The follicles redden and inflame causing bumps (papules) to develop.
		Fruit acid creams (e.g., salicylic acid) are sometimes effective in unplugging the follicles.

		Muscles, oil glands (sebaceous glands), and nerves extend from the follicle into the next layer of the skin — the dermis.
		Inside the follicles, sebum (oil) carries the dead cells to the surface.
		Some contain salicylic acid, which helps to normalize follicle shedding and to exfoliate the top layers of skin.
