研究概览
简要总结
The study aims to investigate the inflammatory response of endothelial cells to various stimulations, in particular the production of IL33 and of endocan in response to allergens, agonists of microorganisms and pollutants.
For that purpose, this project attempts to set up a biological collection of lung and umbilical cord endothelial cells.
Lung endothelial cells are resected from a surgical specimen, resulting from a lung cancer surgery.
Umbilical cord-derived endothelial cells are taken from the umbilical cord collected during the delivery.
