Transgenic pigs as animal models for xenogeneic transplantation: A collaborative project is underway to examine the genetic engineering of porcine tissues to resist the destructive effects of human complement-mediated hyperacute reaction.
The Sertoli Cell and Spermatogeneses: The Sertoli cell plays an important supporting and controlling role in the production of sperm cells. Compensatory hypertrophy/hyperplasia in unilaterally castrated animals has been used as a model system to study spermatogeneses and particularly the role of the Sertoli cell in this process.
Use of Multimedia Backgrounder Computer Aided Instruction Modules in Improving Teaching: Instructors must deal with the disparity between the level at which they wish to teach and the level of the least-well-prepared students. This is most difficult in introductory courses, to which freshmen come from very different backgrounds. It is further aggravated in animal science where some students come from a farm background or vocational agricultural high schools and know agricultural vocabulary and concepts. Three multimedia computer aided instruction modules are being developed in an effort to address this problem. These modules will allow less well prepared students to obtain the prerequisite knowledge and allow the class to function at a more advanced level.
