Viability results of the test made using the MTT assay on fibroblast cells (HGF-1). Control is (HGF-1) without sample. (a) Sample HAP; (b) sample HAPEu3%; (c) sample HAPEu5%; (d) sample HAPEu10%; (e) sample HAPEu20%. (f) Results of the viability tests made using the MTT assay on HeLa cells with sample HAPEu5%+5FU. Control is HeLa cells without HAP sample. (g) Results of viability tests using the MTT assay 5-fluorouracil (5-FU) against HeLa cells.
