Horses may be used when a large amount of antiserum is needed
Primates may be used in research related to vaccine development
Experimental Systems • Experimental animal models include mice • easy to handle • genetically well characterized • rapid breeding cycle • Inbred strains (syngeneic) • repeated inbreeding between litter mates • C3H • C57BL/6
Comments on the use of animals in research and teaching Ethical issue?
Adoptive-transfer systems • First the immune response of a syngeneic host is destroyed • eliminate with x-ray (650-750 rads) • then reconstitute with other lymphocytes • X-ray will lead to death of the mouse unless reconstitution is accomplished
Experimental Systems • Scid mice • must be raised in a germ-free environment • can accept transplanted bone marrow cells • Cell culture systems • primary lymphoid cell cultures • cloned lymphoid cell lines • hybrid lymphoid cell lines
SCID mice grafted with human scalp and treated with X-ray to study hair loss
Fetal tissue research Ethical issue?
Human embryonic stem cells(see Science, vol 282, p 1061) • Pluripotential stem cells can generate all of the cells types and can self renew • Now human ES cells from the blastocyst can be grown in culture • Have been used to produce transgenic mice • With refinement in techniques we may produce directed, lineage restricted differentiation
Assignment • Read Chapter 1 (Overview) for information and review only • Read Chapter 2, Experimental Systems • Review question 12 (pg 45)
