Archivos de Bronconeumologia is an international journal that publishes original studies whose content is based upon results of research initiatives dealing with several aspects of respiratory medicine including epidemiology, respiratory physiology, pathophysiology of respiratory diseases, clinical management, thoracic surgery, pediatric lung diseases, respiratory critical care, respiratory allergy and basic research. Other types of articles such as editorials, reviews, and different types of letters are also published in the journal. Additionally, the journal expresses the voice of the following scientific societies: the Spanish Respiratory Society of Pneumology and Thoracic Surgery (SEPAR; https://www.separ.es/), the Latin American Thoracic Society (ALAT; https://alatorax.org/), and the Iberian American Association of Thoracic Surgery (AIACT; http://www.aiatorax.com/).

It is a monthly journal in which all manuscripts are sent to peer-review and handled by the editor or an associate editor from the team and the final decision is made on the basis of the comments from the expert reviewers and the editors. The journal is published solely in English. All the published data is composed of novel manuscripts not previously published in any other journal and not being in consideration for publication in any other journal..

The journal is indexed at Science Citation Index Expanded, Medline/Pubmed, Embase and SCOPUS. Access to any published article is possible through the journal's web page as well as from Pubmed, ScienceDirect, and other international databases. Furthermore, the journal is also present in X, Facebook and Linkedin. Manuscripts can be submitted electronically using the following web site: https://www.editorialmanager.com/ARBR/.

Objective

Cell cultures provide a good model for studying lung diseases but they are difficult to reproduce and the number of cells obtained is limited. The aim of this study was to develop a way to increase the production of human bronchial epithelial cells (BEC) in primary cultures.

Materialand methods

A total of 12 samples (9 from surgical specimens and 3 from endoscopic biopsies) were processed on plates coated with type I collagen with growth medium supplemented for BEC. When cell proliferation started, the explants were removed for successive subculturing. The remaining cells were left to proliferate and were trypsinized after 50% confluence. We recorded the number of cells obtained, cell viability, and the percentage positive for cytokeratin 7.

Results

The total number of cells obtained by this method was 3-fold the number of human BEC obtained with simple primary cultures. The maximum number of subcultures was 5, mean (SD) cell viability was 91.9% (11.7%), and the percentage of cells positive for cytokeratin 7 was 30.71% (10.68%).

Conclusions

The described method for expanding primary BEC cultures increases cell production.

Objetivo

LOS cultivos celulares son un buen modelo para el estudio de las enfermedades pulmonares, pero son difíciles de reproducir y producen un número limitado de células. El objetivo de este estudio ha sido desarrollar un método que incrementase la producción de células epiteliales bronquiales (CEB) humanas en cultivos primarios.

Materialy métodos

Se procesó un total de 12 muestras (9 procedentes de muestras quirúrgicas y 3 de biopsias endoscópicas) en placas recubiertas de colágeno tipo I con medio suplementado para CEB. Al iniciarse la proliferación celular a su alrededor, los explantes se extrajeron y subcultivaron sucesivamente. Las células restantes se dejaron proliferar y se tripsinizaron tras alcanzar más del 50% de confluencia. Se valoraron el número de células obtenidas, la viabilidad y la citoqueratina 7.

Resultados

El número total de células obtenidas con este método superó en una media de 3 veces el número de CEB humanas obtenidas en cultivos primarios simples. El número máximo de subcultivos fue de 5, la viabilidad media (± desviación estándar) fue de 91,9 ± 11,7% y el porcentaje de células positivas para la citoqueratina 7 del 30,71 ± 10,68%.

Conclusiones

El método descrito para amplificar cultivos primarios de CEB permite incrementar la producción de células obtenidas.
