Cyclic dermal BMP signalling regulates stem cell activation during hair regeneration [PDF]

, 2008
In the age of stem cell engineering it is critical to understand how stem cell activity is regulated during regeneration. Hairs are mini-organs that undergo cyclic regeneration throughout adult life1, and are an important model for organ regeneration ...

Disordered follicle development [PDF]

Molecular and Cellular Endocrinology, 2013
Alterations of ovarian follicle morphology and function have been well documented in women with PCOS. These include increased numbers of growing preantral follicles, failure of follicle growth beyond the mid-antral stage, evidence of granulosa call degeneration, and theca cell hyperplasia.

Combined transcriptome and metabolome analysis of chicken follicles in Tengchong Snow Chicken follicle selection [PDF]

Animal Bioscience
Objective The development of pre-hierarchical follicles (PHFs), especially small yellow follicles (SYFs), directly affects the recruitment of dominant follicles and subsequently affects the egg-laying performance of chickens.

Age as A Predictor of Embryo Quality Regardless of The Quantitative Ovarian Response [PDF]

International Journal of Fertility and Sterility, 2017
Background One determining factor of a successful in vitro fertilization (IVF) cycle is embryo quality. The aim of the present study was to evaluate associations of embryo quality and reserve markers like age, FSH and AMH.

Assembly of the Inner Perivitelline Layer, a Homo log of the Mammalian Zona Pellucida: An Immunohistochemical and Ultrastructural Study [PDF]

, 2012
The avian inner perivitelline layer (IPVL), a homologous structure to the mammalian zona pellucida, is deposited between the granulosa cells and the oocyte cell membrane during folliculogenesis. The glycoprotein meshwork of the IPVL forms a 3-dimensional

Empty follicle syndrome [PDF]

Clinical and Experimental Reproductive Medicine, 2012
Empty follicle syndrome (EFS) is a condition in which no oocytes are retrieved after an apparently adequate ovarian response to stimulation and meticulous follicular aspiration. EFS can be classified into 'genuine' and 'false' types according to hCG levels. It is a rare condition of obscure etiology. The existence of genuine EFS has been questioned and

Optimal Timing of Ovulation Triggering to Achieve Highest Success Rates in Natural Cycles—An Analysis Based on Follicle Size and Oestradiol Concentration in Natural Cycle IVF

Frontiers in Endocrinology, 2022
IntroductionTiming of ovulation triggering is essential in infertility treatments including treatments based on natural menstrual cycles. However, data on follicle size and oestradiol (E2) concentration are limited.
