Camel milk and urine has traditionally been used to treat cancer, but this practice awaits scientific scrutiny, in particular its role in tumor angiogenesis, the key step involved in tumor growth and metastasis. We aimed to investigate the effects of camel milk and urine on key components of inflammatory angiogenesis in the murine cannulated sponge implant angiogenesis model. Polyester‐polyurethane sponges, used as a framework for fibrovascular tissue growth, were implanted in Swiss albino mice and camel milk and urine (25, 50 and 100 mg/kg/day) was administered for 14 days through installed cannula. The implants collected at day 14 post‐implantation, were processed for the assessment of hemoglobin (Hb), myeloperoxidase (MPO), N‐acetylglucosaminidase (NAG) and collagen, which were used as indices for angiogenesis, neutrophil and macrophage accumulation and extracellular matrix deposition, respectively. Relevant inammatory, angiogenic and brogenic cytokines were also determined. Camel milk and urine systemic treatment attenuated the main components of the brovascular tissue, wet weight, vascularization (Hb content), macrophage recruitment (NAG activity), collagen deposition and the levels of vascular endothelial growth factor (VEGF), Interleukin (IL)‐1β, IL‐6, IL‐17, tumor Necrosis Factor (TNF)‐α and transforming growth factor (TGF‐β) in a dose dependent manner. Camel milk and urine treatment reduced VEGF expression and microvessel density in vivo. A regulatory function of camel milk and urine on multiple parameters of the main components of inflammatory angiogenesis has been revealed giving insight into the potential therapeutic benefit underlying the anti‐cancer actions of camel urine.
