Histological examination of the lungs showing the potent anti-metastatic activity of SR4987PTX treatment. a HE staining shows the presence of several B16 lung nodules (black arrows) in control mice (CTRL) and in SR4987 treated mice. Some metastasis are present in mice treated with a very high dose of PTX (10 mg/kg), while mice treated with SR4987PTX appear without metastatic nodules. b Fontana-Masson staining shows the presence of lung micrometastasis (red arrows) in PTX and their absence in SR4987PTX treated mice (boxes 600x magnifications)
