Cryptorchidism: Novel genetic insights into CCDC149 mutations
Andrology, EarlyView.Abstract Background Cryptorchidism, characterized by the failure of one or both testes to descend into the scrotum, is a common congenital condition that can lead to infertility and increased risk of testicular cancer. CCDC149, a coiled‐coil domain‐containing protein, has been implicated in various developmental processes, but its role in the male ...

Acta Zoologica, EarlyView.Abstract Egg laying begins with the orderly development of follicles in the chicken ovaries and transportation through the oviduct with deposition of nutrients until the eggs are produced. However, the ovarian follicles and oviduct morphology of Lohmann Brown and Potchefstroom Koekoek laying hens have not yet been studied.

The evolution of reproduction in Ediacaran–Cambrian metazoans
Biological Reviews, EarlyView.ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

Advances in the Study of Pluripotent Stem Cells in Livestock
Cell Proliferation, EarlyView.Livestock pluripotent stem cells include embryonic stem cells (ESCs) isolated from the inner cell mass of blastocysts and induced pluripotent stem cells (iPSCs) derived from somatic cell reprogramming. They hold significant potential for applications in livestock breed improvement, rapid propagation, human disease modelling and human organ ...

Reproductive System Structure, Development and Function in Cephalopods with a New General Scale for Maturity Stages [PDF]
, 1992 The main types of reproductive system structure, development and functions in cephalopods are described from personal observations and use of the literature. There is one type in males and three in females which are order specific.

Multi‐Omics Reveal the Metabolic Changes in Cumulus Cells During Aging
Cell Proliferation, EarlyView.Fatty acid β‐oxidation was elevated in cumulus cells from older mice. Tryptophan metabolism in aged cumulus cells was active. Supplementing with 5‐HT could mitigate aging damage in oocytes. ABSTRACT Maternal age has been reported to impair oocyte quality.
