Mouse testis development and function are differently regulated by follicle-stimulating hormone receptors signaling during fetal and prepubertal life.

PLoS ONE, 2012
It is currently admitted that Follicle-Stimulating Hormone (FSH) is physiologically involved in the development and function of fetal/neonatal Sertoli cells in the rat but not the mouse.

Luteinizing hormone-like and follicle-stimulating hormone-like activities of equine chorionic gonadotropin β-subunit mutants in cells expressing rat luteinizing hormone/chorionic gonadotropin receptor and rat follicle-stimulating hormone receptor

Animal Cells and Systems, 2021
To identify the specific region of eCG involved in FSH-like activity, the following mutant expression vectors were constructed targeting the amino acid residues 102–104 of the eCG β-subunit: single mutants, eCGβV102G/α, eCGβF103P/α, and eCGβR104K/α ...

Species-specific differences in follicular antral sizes result from diffusion-based limitations on the thickness of the granulosa cell layer

, 2013
The size of mature oocytes is similar across mammalian species, yet the size of ovarian follicles increases with species size, with some ovarian follicles reaching diameters more than 1000-fold the size of the enclosed oocyte.

Gonadotropin and kisspeptin gene expression, but not GnRH, are impaired in cFOS deficient mice. [PDF]

, 2015
cFOS is a pleiotropic transcription factor, which binds to the AP1 site in the promoter of target genes. In the pituitary gonadotropes, cFOS mediates induction of FSHβ and GnRH receptor genes.

Leptin receptor in the chicken ovary: potential involvement in ovarian dysfunction of ad libitum-fed broiler breeder hens [PDF]

, 2004
In hens, the ovarian follicles committed to ovulation are arranged in an ordered follicular hierarchy. In standard broiler breeders hens genetically selected for high growth rate the reproductive function is clearly dysfunctional.

An update on the potential for male contraception : emerging options [PDF]

, 2013
The human population continues to grow and is estimated to rise to 10.1 billion by the end of the century. Therefore, there is still an unmet need for safe and highly effective contraceptive options for both men and women.

Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes

Advanced Functional Materials, EarlyView.
Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...

Programmable Microscale Actuation of Hydrogels With Tunable Response via Printing on Particles

Advanced Materials Technologies, EarlyView.
We fabricate microscale hydrogels with precisely tunable phase transition temperatures (23–60 °C) by particle‐templated two‐photon polymerization using chemically tailored inks. Multi‐material printing enables stepwise thermal actuation through sequential volume changes at distinct VPTTs, while pH‐dependent hysteresis drives anisotropic actuation with ...

Extragonadal FSH Receptor: Is It Real?1

Biology of Reproduction, 2014
Follicle-stimulating hormone (FSH) is a pituitary gonadotroph-derived heterodimeric glycoprotein that binds G protein-coupled FSH receptors (FSHRs) on ovarian granulosa cells [1–3]. This FSH/FSHR signaling pathway is essential for female fertility because null mice lacking either the FSH ligand [4] or FSHR [5, 6] are sterile as a result of preantral ...
