The annual killifish Austrofundulus limnaeus inhabits ephemeral ponds in northern Venezuela, South America, and is an emerging extremophile model for vertebrate diapause, stress tolerance, and evolution. Embryos of A. limnaeus regularly experience extended periods of desiccation and anoxia as a part of their natural history and have unique metabolic and developmental adaptations. Currently, there are limited genomic resources available for gene expression and evolutionary studies that can take advantage of A. limnaeus as a unique model system.

The number of myofiber is determined during the embryonic stage and does not increase during the postnatal period for birds, including goose. Thus, muscle production of adult goose is pre-determined during embryogenesis.

Muscle is the predominant portion of any meat product, and growth performance and product quality are the core of modern breeding. The embryonic period is highly critical for muscle development, the number, shape and structure of muscle fibers are determined at the embryonic stage.

Various studies of chicken muscle development have focused on identifying miRNAs that are important for embryo or adult muscle development. However, little is known about the role of miRNAs in the whole muscle development process from embryonic to post-hatching periods.

The embryonic day E10–13 period of mouse heart development is characterized by robust cardiomyocyte proliferation that creates the compact zone of thickened ventricular wall myocardium. This process is initiated by the formation of the epicardium on the outer heart surface, which releases insulinlike growth factor 2 (IGF2) as the primary cardiomyocyte mitogen.

Mecp2 null mice model Rett syndrome (RTT) a human neurological disorder affecting females after apparent normal pre- and peri-natal developmental periods. Neuroanatomical studies in cerebral cortex of RTT mouse models revealed delayed maturation of neuronal morphology and autonomous as well as non-cell autonomous reduction in dendritic complexity of postnatal cortical neurons.

Embryonic mortality (EM) is a major concern in the dairy industry across the world and it occurs due to loss of conceptus following fertilization until days 42-45 of pregnancy. The present study was carried out with the objective to detect EM in the crossbred cattle at the University Livestock Farm, Mannuthy, Kerala Veterinary and Animal Sciences University during the period from September 2017 to August 2019. Among the breedable animals inseminated at spontaneous oestrus, non-return animals (n=362) were selected for the study.

Cattle is one of the major livestock species for milk production, contributing significantly to the economy of our country and continuous milk production needs regular conception and successful calf crop production. World-over, for dairy economy, there is emphasis on one calf per year per cattle. Successful calving follows survival of the conceptus through embryonic and fetal development.

The Wnt signaling pathway is evolutionary conserved and controls many biological processes like cell proliferation and differentiation. It also provides planar polarity, regulation of the cell cycle, and cell adhesion during both the embryonic and adult period.
