Figure 3 shows the fluorescent staining we obtained with the use of the specific anti-MG probe on NBF-1 and NBF-2 normal fibroblasts of primary cultures originated from the two non-cancer breast tissue samples and on cells of the NDF transformed normal cell line originated from dermal fibroblasts, all cultures having been done in normoxic low or high glucose concentration. The gene discussed is MGAM; the disease is cancer.
