The respiratory epithelium is the first line of contact with the external hazards. Thus it can be damaged and need to be replaced to avoid healing by fibrosis. Tracheal tissue engineering is an alternative promising treatment modality. Mesenchymal stem cell markers are surface proteins, which are responsible for some of these cells unique properties. The objective of this study was to detect the mesenchymal stem cell phenotype among the human nasal respiratory epithelial cells via two immunophenotyping techniques. Respiratory epithelial cells were cultured using co-culture technique, fibroblasts was removed at confluence leaving respiratory epithelial cells, which were passage further to passage 4. Cells were evaluated for mesenchymal stem cell markers that were CD73, CD90, CD105 and the hematopoietic stem cell marker CD45 at passage 1 (P1) and passage 4 (P4) using Flow cytometry and Immunocytochemistry techniques. Respiratory epithelial cells expressed the mesenchymal stem cell markers at P1 and maintain the expression these markers until P4. Using both techniques, to compare the values of mesenchymal stem cell markers expression at P1 to P4 there was no significant difference. This study indicates that respiratory epithelial cells derived from nasal turbinate retain some of mesenchymal stem cells properties even after serial passages. Both methods of Immunophenotyping are comparable.
