Voorbeelden van follicle

• A gland may be a simple pocket, or follicle, as is an oil gland of the skin, or it may be an aggregate of such glands, as is the liver. 

• The hair grows from the bottom of the follicle by a multiplication of the cells covering the papilla upon which its root is moulded. 

• The quantity of hair varies according to the proximity and condition of the follicles. 

• The saliva is composed of four elementary secretions, derived respectively, from the mucous follicles of the mouth, and the parotid, the submaxillary, and the sublingual glands. 

• These glands terminating in the hair follicles secrete an oily substance, which bathes and lubricates as well as nourishes the hair. 

• Eggs and follicles were photographed by immunofluorescence microscopy.

• The cultured follicles developed an antrum, demonstrating that the follicles survived.

• The total numbers of follicles are given in parentheses.

• In the primordial follicle oocytes reach the dictyate stage of prophase 1, at which point meiotic arrests occurs.

• The development and maturation of a follicle are highly involved processes.

• Extracellular and intracellular factors affecting nuclear and cytoplasmic maturation of porcine oocytes collected from different sizes of follicles.

• The resumption of meiotic maturation can be triggered also after the liberation of the oocytes from their follicles in vitro.

• The follicle cells have an ovoid nucleus containing a large prominent nucleolus with a conspicuous granular component.

• Cloned transgenic offspring resulting from somatic cell nuclear transfer in the goat: oocytes derived from both follicle-stimulating hormone-stimulated and nonstimulated abattoir-derived ovaries.

• Co-culture of mouse embryos with cells isolated from the human ovarian follicle, oviduct and uterine endometrium.

• Isolated follicles were measured with an eyepiece micrometer in a stereoscopic microscope.

• Isolated follicles were measured with an eyepiece micrometer in a microscope stereoscope.

• Fractionation did not induce any notable changes in follicle size.

• Follicular volumes increased with maturity of the follicle.

• Induction of maturation in cumulus cell-enclosed mouse oocytes by follicle stimulating hormone and epidermal growth factor: evidence for a positive stimulus of somatic cell origin.
