CD Hairless


This spontaneous mutation model was isolated from a Crl:CD(SD) colony in Charles River, in the late 1980s. Rederived in 1993 and subsequently transferred to Charles River, Raleigh, NC for barrier room production. The model does not exhibit the typical characteristics of hair growth and loss found in other hairless models. Specific genetic analysis to identify the mutation has not been undertaken. Histopathology has determined the model is euthymic.
