Abstract

The area vasculosa of the chick embryo is subdivided into two concentric zones: the inner transparent area pellucida vasculosa (AVP) and the less transparent surrounding area opaca vasculosa (AOV). The different optical properties of these zones are caused by the different morphology of the endoderm, which consists of flat cells in the APV and of high-prismatic cells containing large yolk vacuoles in the AOV. The present study describes how this endodermal subdivision of the area vasculosa is related to the development of the extraembryonic vascular pattern. By injection of ink into the vascular system of chick embryos at stages 12 to 20 (Hamburger and Hamilton 1951 "HH"), it has been demonstrated that the vascular net of the area vasculosa from stage 14 (HH) onwards develops into different patterns in APV and AOV. The small loops of uniform capillary vessels of stage 13 (HH) are widened due to the rapid expansion of the extraembryonic mesoderm. In the AOV from stage 14 (HH) onwards numerous small blood vessels sprout into the enlarged intervascular spaces. This process is maximal at stage 17 (HH). In contrast, the blood vessels of the APV remain largely unbranched. These findings suggest that the development of the extraembryo...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
