Follicle Structure Influences the Availability of Oxygen to the Oocyte in Antral Follicles [PDF]

Computational and Mathematical Methods in Medicine, 2011
The ability of an oocyte to successfully mature is highly dependent on intrafollicular conditions, including the size and structure of the follicle. Here we present a mathematical model of oxygen transport in the antral follicle. We relate mean oxygen concentration in follicular fluid of bovine follicles to the concentration in the immediate vicinity ...

Apoptosis in the Hair Follicle [PDF]

Journal of Investigative Dermatology, 2006
Apoptosis plays an important role in many physiological processes, ranging from morphogenetic events to adult tissue homeostasis, and defects in its regulation contribute to many disorders. Here we review molecular mechanisms of apoptosis in the hair follicle (HF), whose cyclical growth pattern is repeatedly interrupted by apoptosis-driven involution ...
