Figure 1: Immunohistochemical detection of human LAM/TSC cells by using COX IV rabbit monoclonal antibody (red staining) in uteri of mice 3 (A) and 6 (B) months after human LAM/TSC cell administration. COX IV positive cells (arrows) are detected in the myometrium layer (X40). Scale bars: 50 μm. Quantification of LAM/TSC cells in uteri was calculated as percentage of COX IV-labelled LAM/TSC cells/ total number of cells in the field (C). Data are expressed as mean ± SEM. *P<0.05 vs n°COX IV labelled cells/ (n°total cells x10-3) of mice 3 months after LAM/TSC cell administration
