Inhibin and activin in embryonic and fetal development in ruminants [PDF]
Inhibin, activin and follistatin are protein hormones with diverse physiological roles. The involvement of inhibin in the regulation of pituitary FSH production and secretion in adult males and non-pregnant females is well established. However, it is unlikely that inhibin plays a similar role in pregnancy in ruminants.

Embryonic and Early Fetal Development of the Human Neocortex [PDF]
Early corticogenesis was studied in human embryos and early fetuses from Carnegie stages 16 to 22 (5–8 gestational weeks) by using immunohistochemistry for Reelin (Reln), calretinin (CR), and glutamic acid decarboxylase (GAD). A first population of Reln-positive cells appears in the neocortical anlage at stage 16 and increases in number at stages 17–18.

Embryonic and fetal development in different genotypes in pigs [PDF]
It is widely accepted that uterine capacity, not ovulation rate, is the greatest restraint on litter size in pigs. Recently, the reproductive strategy(s) of the Chinese Meishan pig, a breed which farrows three to five more piglets per litter than US or European pig breeds, has come under intense scrutiny.

Establishing in vivo and ex vivo chick embryo models to investigate fetal tendon healing
Injured adult tendons heal fibrotically and possess high re-injury rates, whereas fetal tendons appear to heal scarlessly. However, knowledge of fetal tendon wound healing is limited due in part to the need for an accessible animal model.

Birth weight is related with bone mineral content in adulthood: results of ELSA-Brasil
OBJECTIVE To investigate the association between birth weight and bone mineral content (BMC), and whether this relationship differs between men and women. METHODS A total of 10,159 participants from the ELSA-Brasil cohort were eligible for this analysis.

Summary: Fetal globin genes are transcriptionally silenced during embryogenesis through hemoglobin switching. Strategies to derepress fetal globin expression in the adult could alleviate symptoms in sickle cell disease and β-thalassemia.

Development of Human Embryonic and Fetal Dermal Vasculature
This report summarizes recent advances in the understanding of the structure and organization of the microvasculature in developing human skin. Previous observations suggested that the skin contains no blood vessels as late as eight weeks estimated gestational age (EGA).

Upper arm posture during human embryonic and fetal development [PDF]
AbstractThe upper extremity posture is characteristic of each Carnegie stage (CS), particularly between CS18 and CS23. Morphogenesis of the shoulder joint complex largely contributes to posture, although the exact position of the shoulder joints has not been described.

Effect of long-acting injectable progesterone supplementation, seven days after insemination, on embryo and fetal development in Nellore cows [PDF]
This study evaluated the effects of long-acting injectable progesterone supplementation (P4LA) on embryonic and fetal development and birth weight in Nellore cows seven days after timed artificial insemination (TAI).
