[A method for the primary culture of fibroblasts isolated from human airway granulation tissues]
1Department of Pulmonary Medicine, Beijing Tiantan Hospital, Capital Medical University, Beijing 100050, China.
Objective:
To establish a feasible method to culture primary fibroblasts isolated from human airway granulation tissues, and therefore to provide experimental data for the investigation of the pathogenesis of benign airway stenosis.
Methods:
The granulation tissues were collected from 6 patients during routine bronchoscopy at our department of Beijing Tiantan Hospital from April to June 2011. Primary fibroblasts were obtained by culturing the explanted tissues. Cell growth was observed under inverted microscope.
Results:
All of these 6 primary cultures were successful. Fibroblast-like cells were observed to migrate from the tissue pieces 3 d after inoculation. After 9-11 d of culture, cells reached to 90% confluence and could be sub-cultured. After passage, the cells were still in a typical elongated spindle-shape and grew well. The cells could be sub-cultured further when they formed a monolayer.
Conclusion:
Explant culture is a reliable method for culturing primary fibroblasts from human airway granulation tissues.
