Abstract

Methods of study of tumour invasiveness in vitro were investigated using the interactions between malignant virally transformed C3H mouse fibroblasts (MO4) with fragments from embryonic chick heart. Invasion of MO4 cells into the heart tissue could be demonstrated in all three-dimensional cultures. On the contrary, seeding of MO4 cells on top of a monolayer of heart cells did not mimic invasion. Precultured heart fragments were more suitable for the study of the early phase of invasion than freshly cut ones because they presented healthy well-delineated borders. Aggregates of MO4 cells proved more suitable than suspensions or monolayer fragments because they were amenable to quantitation, were not traumatized or treated with enzymes during harvest. They allowed precise control of the initial site of contact with the heart tissue. The nature of the culture medium predominantly affected the growth of the MO4 population. This factor influenced the pattern of invasion quantitatively, but did not alter the invasive capacity of the MO4 cells itself. In cultures on adhesive substrates the interaction between the MO4 cells and the heart tissue was complicated by the fact that both also interacted with the aritficial substrate.

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.
