What is a transgenic animal?• Transgenic animal: An organism that has had part of another species genome transferred into its own through the techniques of genetic engineering.• Example of a transgenic animal: Mice
How do you create a Transgenic Mouse?•Several methods but one most often used: Transgenic Mouse Process Animation
First Method of Transgenic Mice Creation• (basic steps) Standard Transgenic Approach: 1. Microinject fertilized mouse eggs with transgene
Methods continued…2. Injected eggs are implanted into a fostermother
Methods continued…3. Offspring are then born “Pups”; possiblefounders (have the transgene)
Method Continued…4. Potential founders (pups with the transgene) are found using a PCR analysis and or southern blotting (Black offspring = founders)5. Founders can then be further analyzed for affectsof that transgene
Methods Continue… Transgenic Mice Technology Part 1 Transgenic Mice Technology Part 2
Why create transgenic mice?•Transgenic Mice have: •Aided the study of Alchemies Disease • Aided in study of pancreatic cancer Transgenic Mice aids study of Pancreatic Cancer •Acted as disease models •Tested toxicants •Produced specific proteins helpful in biotechnology
Pros and Cons• Pros – Cheap – Short generation time – Defined genes• Cons – Ethical Concerns • Are the animals treated with respect? – Environmental Issues • What if a genetically modified animal gets loose? – Religious Views • Do we have the right to act as God?
