Histopathology of organs from BALB/c mice upon eCATH1 treatment. The organs of untreated mice and mice receiving a daily subcutaneous dose of 1 mg/kg body weight of eCATH1 for 7 days were stained with hematoxylin and eosin. Representative examples are shown of small intestine (a), kidney (b), liver (c), lung (d), spleen (e), and stomach (f) sections. The histopathology analysis did not reveal any histological changes between treated and nontreated mice.
