Hints and discussion topics from Scott Gilbert

1. Most students don't know what a salamander or sea urchin is. In my introductions to fertilization (when I discuss these creatures), I often bring in the adult even if we're not going to do any experiments with the beasts.

2. There's a lot of "down" time in many developmental bio. and embryology labs. We wait for the cleavage of the urchin or the imaginal disc to evert, etc. This is a good time to introduce students to some of the ethical and philosophical issues of developmental biology. Some topics (and references to give to the student) include:

(A) Germ-line gene therapy
Danks, D. M. 1994. Germ-line gene therapy: No place in the treatment of genetic disease. Human Genet. Therap. 5: 151 - 153.
Wivel, N. A. and Walter, L. 1993. Germ line modification and disease prevention: Some medical and ethical perspectives. Science 262: 533 - 538.

(B) Pre-conception sex selection
Peter, A. T., Jones, P. P., and Robinson, J. P. 1992. Fractionation of bovine spermatozoa for sex selection: A rapid immunomagnetic technique to remove spermatozoa that contain the H-Y antigen. Theriogen. 40: 1177 - 1185.
Shushan, A. and Schenker, J. G. 1993. Prenatal sex determination and selection. Human Reprod. 8: 1545 - 1549.

(C) Gendered metaphors of fertilization and meiosis
Biology and Gender Study Group 1988. The importance of feminist critique for contemporary cell biology. Hypatia 3: 61 - 76.
Martin, E. 1991. The sperm and the egg. Signs 16: 485-501.
Small, M. F. 1991. Sperm Wars. Discover (July): 48 - 53. (Blatant examples)
Gross, P. R. and Levitt, N. 1994. Higher Superstition: The Academic Left and its Quarrels with Science. Johns Hopkins University Press. (Exerpts of Ch. 5). (They think this whole critique is wrong).

(D) Alcohol as a teratogen
Does one have the right/moral responsibility to go over to a table in a restaurant and stop a pregnant woman from drinking alcohol? Michael Dorris says you do. Chapters from his book The Broken Cord (Harper and Row) can stimulate vehement arguements in the lab.
