Standardization and performance evaluation of a virus isolation technique using murine neuroblastoma cell line (N2A) for the rabies virus (RABV) surveillance in Pará State, Brazil

Rev. bras. ciênc. vet; 30 (3), 2023
Rabies is a zoonotic disease caused by the rabies virus (RABV) from the Lyssavirus rabies species. In humans, around 60,000 deaths are registered annually in the world due to the disease, while accurate estimation of rabies incidence among other animals, mainly in wildlife, is unfeasible. In recent decad...

Aislación y caracterización de las células epiteliales del amnios

Int. j. morphol; 40 (3), 2022
RESUMEN: Las células epiteliales del amnios (hAECs) son células madre pluripotenciales; tienen capacidad de diferenciarse en células de las tres capas embrionarias. Como tales, se utilizan en algunas terapias regenerativas en medicina. Este estudio tiene por objetivo describir un protocolo de aislaci�...

Impact of cell harvesting methods on detection of cell surface proteins and apoptotic markers

Braz. j. med. biol. res; 54 (2), 2021
Assays based on the flow cytometry technique allow a convenient analysis of multiple cellular parameters; however, their results should be interpreted cautiously due to a strong impact of confounding factors. Different techniques in cell culturing such as either enzymatic or mechanic detachment of adhere...

Phenotype changes of oral epithelial stem cells after in vitro culture

Abstract The aim of our study was to isolate populations of keratinocyte stem cells based on the expression of cell surface markers and to investigate whether the culture could affect their phenotype. keratinocytes from human oral mucosa were sorted based on the expression of the epithelial stem cell mar...

A modified method by differential adhesion for enrichment of bladder cancer stem cells

Int. braz. j. urol; 42 (4), 2016
ABSTRACT Purpose: In a previous study the vaccine was effective against bladder cancer in a mouse model. However, a small portion of tumors regrew because the vaccine could not eliminate bladder cancer stem cells (CSCs). In this study, we showed a modified method for the isolation of bladder CSCs using ...

Lacrimal gland primary acinar cell culture: the role of insulin

Arq. bras. oftalmol; 79 (2), 2016
ABSTRACT Purpose: The goal of the present study was to establish a protocol for primary culture of lacrimal gland acinar cells (LGACs) and to assess the effect of adding insulin to the culture media. Methods: LGACs were isolated and cultured from lacrimal glands of Wistar male rats. The study outcomes ...
