Sampling, Trimming and Embedding Guides

The interactive guides and images were created by David Savio and Beth Mahler. Three guides from RITA and NACAD are for organ sampling and trimming in rats and mice. These guides were originally published in Experimental Toxic Pathology, in 2003, Vol. 55, publisher: URBAN & FISCHER
