Experimental bone tumors as models of human bone tumors

Experimental models of human bone tumors may be classified as causal, descriptive, and selective models. These models are useful for analyzing the morphology, biology, and therapy of human bone tumors. The application of these models, however, requires us to define clearly the questions to be answered and to consider the special features of experimental and human bone tumors. The suitability of experimental bone tumors as models can be determined only on the basis of a large amount of relevant experimental and clinical data.
