BARCELONA, Spain, July 29, 2019 -- A new study performed here shows that during the embryonic development
of the brain, the cells between adjacent segments detect the mechanical forces generated during morphogenesis to regulate the balance between progenitor stem cells and differentiated neurons.
Summary: TEHRAN (FNA)- New study uses live imaging to understand a critical step in early embryonic development
-- how genes and molecules control forces to orchestrate the emergence of form in the developing embryo.
Temperature has a drastic impact on embryonic development
in cephalopods (Boletzky 1987, Repolho et al.
These signaling pathways are pivotal during embryonic development
and continue to play a part in regenerating certain bodily tissues into adulthood.
The researchers from RMIT University have for the first time incorporated the natural processes of embryonic development
to build a material that can more naturally communicate with stem cells for effective tissue repair.
A similar effect was achieved by the application of temperatures higher and lower than the optimum during the first days of spider embryonic development
(Jacunski and Templin, 2003; Templin et al., 2009).
Getting as close as possible to in-vivo incubation conditions is essential to ensure the most favorable environment for embryonic development
, given that exposure to non-optimal conditions outside of an incubator may affect the viability and quality of embryos.
Their topics include gut health and susceptibility to enteric bacterial disease in poultry, understanding and boosting poultry immune systems, leg disorders in poultry: bacterial chondronecrosis with osteomyelitis (BCO), the effect of incubation temperature on embryonic development
in poultry, the contribution of environmental enrichment to sustainable poultry production, and developments in humane slaughtering techniques for poultry.
The researchers identified a protein called agrin, which is expressed during embryonic development
but stops shortly after birth.
The researchers found that while most transcription factors are incapable of binding to DNA sequences containing methylated cytosine, some transcription factors actually prefer the methylated version, including some factors that play a key role in embryonic development
, and in the development of prostate and colorectal cancers.
