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.

POGZ Is Required for Silencing Mouse Embryonic β-like Hemoglobin and Human Fetal Hemoglobin Expression

Cell Reports, 2018
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.

Meta-analysis of the incidence of pregnancy losses in dairy cows at different stages to 90 days of gestation

JDS Communications, 2023
Pregnancy losses are a biological challenge and economically important in dairy herds. A meta-analysis was conducted to quantify losses in 4 periods from 19 to 90 d of pregnancy corresponding to the physiological development of gestation in dairy cows. A

Superovulation of female mice delays embryonic and fetal development [PDF]

Human Reproduction, 2001
Mouse and human embryos, cultured in vitro, undergo a delay in development compared with those grown in vivo. This delay can be caused by suboptimal culture conditions, but possible influences of ovarian stimulation cannot be excluded. The objective of this study was to test the hypothesis that both in vitro and in vivo, preimplantation embryonic ...

Circadian clocks during embryonic and fetal development

Birth Defects Research Part C: Embryo Today: Reviews, 2007
AbstractCircadian rhythmicity is a fundamental characteristic of organisms, which helps ensure that vital functions occur in an appropriate and precise temporal sequence and in accordance with cyclic environmental changes. Living beings are endowed with a system of biological clocks that measure time on a 24‐hr basis, termed the circadian timing system.

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.

Prenatal Development and Function of Human Mononuclear Phagocytes

Frontiers in Cell and Developmental Biology, 2021
The human mononuclear phagocyte (MP) system, which includes dendritic cells, monocytes, and macrophages, is a critical regulator of innate and adaptive immune responses. During embryonic development, MPs derive sequentially in yolk sac progenitors, fetal
