No Evidence of Impact of Genetic Sex on Hyperthermia-Induced Neural Tube Defects in Chicken Embryos. [PDF]
Birth Defects ResABSTRACT Background In mammals, cranial neural tube defects (NTDs) are more likely to occur in females. It has been proposed that the sex bias in NTDs was due to the presence of the inactive X chromosome in the somatic cells of female embryos and that the inactive X acted as a heterochromatic sink, competing for silencing factors with the rest of the ...

Oldest preserved umbilical scar reveals dinosaurs had ‘belly buttons’
BMC Biology, 2022 Background In egg-laying amniotes, the developing embryo is tethered to a number of the extraembryonic membranes including the yolk sac and allantois that deliver oxygen and nutrients and remove metabolic waste products throughout embryonic development ...

New Insights Into the Role of β-NGF/TrKA System in the Endometrium of Alpacas During Early Pregnancy
Frontiers in Veterinary Science, 2021 One striking reproductive feature in South American camelids is that more than 90% of gestations are established in the left uterine horn (LUH). This phenomenon could be related to a differential vascular irrigation of the LUH.
