Identification of side population cells in mouse primordial germ cells and prenatal testis [PDF]
, 2011 In mammals, the stem cells of spermatogenesis are derived from an embryonic cell population called primordial germ cells (PGCs). Spermatogonial stem cells displaying the "side population" (SP) phenotype have been identified in the immature and adult ...

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment
The Anatomical Record, EarlyView.Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Gonad Maturation of Clown Loach (Botia macracanthus) in Pond
Jurnal Akuakultur Indonesia, 2007 <p>The objective of this research is to know the gonad maturation of clown loach <em>{Botia macracanthus) </em>reared in pond. Two groups contain 4 female broodstock; I) carried and II) non-carried egg broodstock were reared in two separated hapas which placed in pond. Each hapa was also stocked nine males.

The Anatomical Record, EarlyView.Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

Investigation of \u3cem\u3ede novo\u3c/em\u3e cholesterol synthetic capacity in the gonads of goldfish (\u3cem\u3eCarassius auratus\u3c/em\u3e) exposed to the phytosterol beta-sitosterol [PDF]
, 2006 Total and intra-mitochondrial gonadal cholesterol concentrations are decreased in fish exposed to the phytoestrogen beta-sitosterol (beta-sit). The present study examined the potential for beta-sit to disrupt de novo cholesterol synthesis in the gonads ...

Thyroid hormone status within the physiological range affects bone mass and density in healthy men at the age of peak bone mass [PDF]
, 2011 Context: The hormonal factors involved in the regulation of peak bone mass (PBM) in men have not been fully investigated. Apart from gonadal steroids and somatotropic hormones, thyroid hormones are known to affect bone maturation and homeostasis and are ...

The Anatomical Record, EarlyView.Abstract Sexual differentiation in the equine fetus involves coordinated morphogenetic processes that shape both the gonads and the genital ducts. Although the formation of testes and ovaries has been relatively well documented, the temporal dynamics and morphometric patterns of the mesonephric (Wolffian) and paramesonephric (Müllerian) ducts remain ...
