Numerical areal density of CD34 and CD117 immunoreactive hematopoietic cells in human fetal and embryonic liver [PDF]
Biomedicinska istraživanja, 2019 Introduction. Hematopoiesis is the process of developing blood cells and the formed elements of blood. This dynamic process occurs postnatally in the bone marrow, while the prenatal hematopoiesis is scattered over multiple localizations.

Perturbation of the hematopoietic system during embryonic liver development due to disruption of polyubiquitin gene Ubc in mice. [PDF]
PLoS ONE, 2012 Disruption of the polyubiquitin gene Ubc leads to a defect in fetal liver development, which can be partially rescued by increasing the amount of ubiquitin.

Embryonic ethanol exposure on zebrafish early development
Brain and Behavior, 2021 Introduction Embryonic exposure to ethanol leads to a condition of physical, behavioral, and cognitive deficiencies named fetal alcohol spectrum disorders (FASD). The most severe variations are in fetal alcohol syndrome (FAS), which is easier to diagnose

Inhibin and activin in embryonic and fetal development in ruminants [PDF]
Bioscientifica Proceedings, 2019 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]
The Journal of Neuroscience, 2000 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]
Bioscientifica Proceedings, 2020 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.

Ontological Differences in First Compared to Third Trimester Human Fetal Placental Chorionic Stem Cells [PDF]
, 2012 Human mesenchymal stromal/stem cells (MSC) isolated from fetal tissues hold promise for use in tissue engineering applications and cell-based therapies, but their collection is restricted ethically and technically.

Establishing in vivo and ex vivo chick embryo models to investigate fetal tendon healing
Scientific Reports, 2023 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.
