We subcutaneously injected collagen wound dressing (CAS) extracts equivalent to the area covering human body surface by 35 and 70%, respectively, into mouse dams from days 6 to 15 of pregnancy. No toxicity was observed in dams and no external, skeletal and visceral anomalies related to CAS treatment were observed in fetuses. It is, therefore, concluded that CAS extracts produces no teratogenesis after subcutaneous injection during organogenesis in mice.
