Cleared and double stained fetal cats. "These fetuses were unexpectedly found during routine dissection of the reproductive and excretory systems of adult cats. Note that the long bones in the limbs are beginning to undergo endochondral ossification, the developmental transition from a cartilaginous precursor to a mineralized bone. This specimen was prepared by Katy Delong, class of 2015. All specimens in the exhibit are obtained from Carolina biological Supply co." Descriptions provided by Dr. Staab. Specimens were enzymatically cleared of soft tissues and double stained for bone (red/purple) and cartilage (blue).
