Oogenesis in cultures derived from adult human ovaries

Reproductive Biology and Endocrinology, 2005
Ten years ago, we reported that in adult human females the ovarian surface epithelium (OSE) is a source of germ cells. Recently, we also demonstrated that new primary follicles are formed by assembly of oocytes with nests of primitive granulosa cells in ...

Rodent Models of Polycystic Ovary Syndrome [PDF]

, 2013
Rodents are clearly valuable models for assessing disruption of fertility. The effects of different steroid treatments at different stages of reproductive life through from fetal to adult have been assessed for effects on fertility, ovarian morphology ...

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Vascular health and exercise in females throughout the lifespan: Exploring puberty, pregnancy and menopause

Experimental Physiology, EarlyView.
Abstract This narrative review highlights the impact of exercise on vascular health in females over the lifespan with an emphasis on puberty, pregnancy and menopause. These events encompass substantial changes in sex hormone levels, particularly oestrogens and progesterone.

Potential Effects of Prepubertal Exposure to Perfluorooctane Sulfonic Acid on the First Wave of Folliculogenesis in Young CD‐1 Mice

Birth Defects Research, Volume 118, Issue 5, May 2026.
ABSTRACT Background Perfluorooctane sulfonic acid (PFOS) belongs to a group of synthetic chemicals referred to as per‐ and polyfluoroalkyl substances (PFAS) that are known to degrade slowly. Exposure to PFOS has been reported to cause birth defects and disrupt female sex hormone levels in mice.

RNA Modifications: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 5, May 2026.
Types of RNA modification. We have summarized the currently common types of RNA modifications, including ac4C, m6A, m1A, m5C, m3C, m7G, and ψ, and visually characterized their features through structural formulas. The characteristic structures are marked with a background color different from the background color.

Ovarian Follicle Disaggregation to Assess Granulosa Cell Viability

International Journal of Clinical Medicine, 2018
Background: Mammalian ovaries contain follicles containing an oocyte enclosed by layers of granulosa cells (GC). Follicle growth and oocyte maturation are largely dependent on GC numbers and viability, but there is no established, reliable method for assessing the number of viable GC within an isolated follicle.

Estrous cycle-dependent changes of Fas expression in the bovine corpus luteum: influence of keratin 8/18 intermediate filaments and cytokines [PDF]

, 2012
Background Fas expression and Fas-induced apoptosis are mechanisms attributed to the selective destruction of cells of the corpus luteum (CL) during luteal regression.

Insights Into Bifenthrin Stereoisomers and Their Regulatory Implications

ChemistryOpen, Volume 15, Issue 5, May 2026.
Bifenthrin is a pyrethroid insecticide with two stereogenic centers, generating four stereoisomers with distinct physicochemical and electronic properties. A combined crystallographic and density functional theory study, supported by Hirshfeld surface, quantum theory of atoms in molecules, natural bond orbital, and reactivity descriptor analyses ...

El sistema reproductor femenino de Zearaja chilensis (Guichenot, 1848) (Chondrichthyes, Rajidae): Gametogénesis y validación microscópica de los criterios de madurez [PDF]

, 2015
Los condrictios son extremadamente susceptibles a la explotación pesquera debido, entre otras cosas, a sus adaptaciones reproductivas. Los conocimientos básicos de sus parámetros reproductivos son esenciales, ya sea desde el punto de vista ecológico como
