14) Immunology
I am not aware of any relevant data.
15) Pathological Features
Griner (1983) reported myocardial necrosis and depicted severe scoliosis in tree shrews. The scoliotic animal also had ankylosing arthritis. A number of parasites have been identified in three shrews, the literature to which is accessible through PubMed.
16) Physiological Data
According to the vascular arrangement described above, the maternal/fetal flow conditions can be described best as a cross-current flow exchanger system. Tree shrews have been investigated anatomically especially for their neural anatomy. Relevant literature is accessible through PubMed.
17) Other Resources
At CRES (San Diego Zoo) fibroblast cell strains are available of only two specie of tree shrews: Tupaia minor and Tupaia tana. They can be made available by contacting Dr. Oliver Ryder at oryder@ucsd.edu.
18) Other Remarks - What additional information is needed?
There is imperfect knowledge of the depth of trophoblastic invasion into blood vessels.
Acknowledgement
The tupaias were derived from a colony of the Schering Company, Berlin, Germany. Dr. Walter Elger, Schering Company kindly provided the placentas as well as most of the endocrine data.
