Section 4. Objectives, Tasks and Schedules

Objectives and Tasks

Objective Task
1. Determine the pretreatment of sperm and the timing of the injection of the sperm relative to egg activation that maximizes male pronuclear development a. Describe the temporal changes in the decondensation of the sperm chromatin and the development of the male pronucleus following normal fertilization
1. b. Pretreat sperm with dithiothreitol and/or sonication before microinjection into the eggs. The measurable endpoint of this task is the proportion of eggs in which a male pronucleus is formed.
1. c. Inject the sperm into eggs at varying times following activation. The measurable endpoint will be the proportion of eggs in which a male pronuclues is formed.
2. Produce viable offspring from the injection of a single sperm into an activated egg a. Inject sperm with the gene for pigmentation into activatived, albino trout eggs (the protocol for sperm pretreatment and the time of injection will be dictated by the results of objective 1). The measurable endpoint will be normal, pigmented fry.
2. b. Inject steelhead sperm into activated steelhead eggs. The measurable endpoint will be normal, diploid fry.
2. c. Inject chinook sperm into activated chinook eggs. The measurable endpoint will be normal, diploid fry.

Section 7. Abstract

Abstract

The genetic contributions of male fish from threatened and endangered species are lost if their sperm cells are unable to fertilize eggs. A similar biological problem, human male factor infertility, exists in medicine. The human reproductive problem has been solved by the development of intracytoplasmic sperm injection (ICSI); normal human offspring are now routinely produced by the injection of a single sperm cell into an egg. Since the post-fertilization cellular events, sperm nuclear decondensation and the formation of the male pronucleus, appear to be very similar between mammals and fish, the overall objective of this proposed investigation is to produce fish by injecting a single sperm into an egg. The hypothesis to be tested is that the mechanical introduction of a sperm into the cytoplasm of an activated egg will result in the decondensation of the chromatin within the sperm nucleus, in the development of a morphologically normal male pronucleus, and in the production of a fully functional zygote. The experiments proposed for FY2000 are designed to develop the methodology of sperm intracytoplasmic injection for fish and to demonstrate that the DNA of the injected nucleus contributes to the genome of the resultant zygote. Ultimately, the ability to produce fish by ICSI is expected to provide the means to retrieve the genetics of sperm 1) from infertile or subfertile males, 2) that has been prematurely activated during collection, 3) that was cryopreserved and accidentally thawed, or 4) from dead or dying males.
