AF = atretic follicle; CA = cortical alveolus; F = follicle cells; FG = fullgrown oocytes; Mi = micropyle; MO = maturing oocyte; N= nucleus/germinal vesicle; NC = nest of oogonia; Nu = nucleolus; OG = oogonium; OL = ovarian lumen; OW = ovarian wall; PG = primary growth oocytes; POC = postovulatory follicle complex; SG = secondary growth oocytes ; Y = yolk globules; ZP = zona pellucida.
During ovarian development, follicle cells were stained with positive PR at each ovarian stage.
They treated the grasshopper Oxya japonica with diflubenzuron and found a retardation of ovarian development causing an increase in the receptor tyrosine kinase present on the adjacent follicle cells. This localized signal from the oocyte to the follicle cells normally leads to dorsal follicle cell delimitation and orientation of the future dorsoventral axis of the embryo.
We suggest that some unidentified functional factors in deer antler, such as IGF-1, may play a role in regulating the hair cycle and follicle cell proliferation in rodents.
However, unlike mammalian oocytes that develop within follicles, nemertean oocytes characteristically lack a surrounding sheath of follicle cells and often respond differently to maturation-related cues than do mammalian oocytes.
Histological analysis of Leptobotia elongata Bleeker ovaries revealed five stages in oocyte development (oogonia, previtellogenic oocytes, vitelline vacuolated oocytes, vitellogenic oocytes and mature oocytes) based on nucleoli, follicle cells and vitellogenesis.
Study suggested that genistein and daidzein decreased pig ovarian follicle cell apoptosis in a dose-responsive manner, and daidzein was more potent than both estradiol and genistein (Suttner et al., 1998).
Activation of a follicle cell surface phospholipase by a tyrosine kinase dependent pathway is an essential event in ascidian fertilization, Mol.
However, primary contact may also occur between the larger, naked egg microvilli that formerly connected with the follicle cell processes [ILLUSTRATION FOR FIGURES 24, 25 OMITTED].
The time at which follicle cell removal was accompanied by only a 50% level of GVBD (= the "[T.sub.1/2] inhibitory time") averaged 37 [+ or -] 12 min (n = 16 ovaries).
Very few follicle cells were visible around the oocytes (Fig.
(2,5,12,13) Stimulation of CB1 receptors in the skin--where they are present in differentiated keratinocytes, hair follicle cells, immune cells, sebaceous glands, and sensory neurons (13) - diminishes pain and pruritus, controls keratinocyte differentiation and proliferation, inhibits hair follicle growth, and regulates the release of damage-induced keratins and inflammatory mediators to maintain cutaneous homeostasis.
