PTPRC and endometriosis: We showed that of total endometriosis cells, the majority of BMDCs engrafting endometriosis were CD45− compared to CD45+ cells (leucocytes) as shown in Figure 3B. AMD3100 significantly reduced the engraftment of GFP+ cells in endometriosis including GFP + CD45+ leucocytes and GFP + CD45− BMDSCs, consistent with a reduction of recruitment of total BMDCs in the lesions.
