Establishment of cell strains from human urothelial carcinoma and their morphological characterization

In Vitro
T KakuyaT Ueda

Abstract

We have examined the conditions for cultivation of enzymatically dispersed cells from 34 human urothelial transitional cell carcinomas (TCC) of various types. By employing two culture methods, stationary and tapping suspension, and by using the synthetic medium DM 160 supplement with human umbilical cord serum and fetal bovine serum, six cell strains were established. In two strains the tapping suspension culture method was suitable for growth of highly malignant cancer cells that detach easily from the glass surface in stationary cultures. Each of the six cell strains has been maintained in culture for over 30 months with repeated subcultures of 32 to 128 times. The histopathological features of the original TCC were three differentiated papillary types and three anaplastic nonpapillary types. In two cell strains from TCC with low malignancy, however, the cancer masses that formed in nude mice differed from the original TCC in which they became more malignant, and one cell strain resembled the original TCC closely. In three stationary culture cell strains the epithelial nature was demonstrated by the presence of desmosomes and tonofilaments. In one cell strain only tonofilaments were present. In two tapping suspension culture ...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.
