Germline Confirmation / Coat Color Markers

Ensures that a targeted genetic modification has been successfully passed through reproductive cells to offspring. Coat-color markers serve as a visible indicator of ES cell contribution in chimeric founder animals.

Overview

Germline confirmation ensures that a targeted genetic modification has been successfully passed through reproductive cells to offspring. Coat-color markers serve as a visible indicator of ES cell contribution in chimeric founder animals.

Frequently Asked Questions

How does coat color indicate ES cell contribution?

After blastocyst injection, ES-cell–derived mice exhibit mixed coat colors based on parental strain background (e.g., agouti × albino), helping identify high-contribution chimeras.

Germline Transmission

The process by which a genetic modification introduced into an organism is passed on to its offspring through reproductive (germ) cells. It confirms that the engineered change is stably integrated into the genome and can be inherited by future generations.

Blastocyst Injection / Chimera Production

The process of introducing genetically modified cells into a developing mouse blastocyst to create a chimera—an organism composed of cells from both the host embryo and the engineered cells.

Breeding Scheme (Hetero × Hetero, etc.)

Planned mating strategies used to generate offspring of specific genotypes—such as heterozygous, homozygous, or compound mutant combinations—from established genetically modified lines.
