Examples of research in which knockout mice have been useful include studying and modeling different kinds of cancer, obesity, heart disease, diabetes, arthritis, substance abuse, anxiety, aging and Parkinson's disease. Knockout mice also offer a biological and scientific context in which drugs and other therapies can be developed and tested.
The International Knockout Mouse Consortium (IKMC) is a scientific endeavour to produce a collection of mouse embryonic stem cell lines that together lack every gene in the genome, and then to distribute the cells to scientific researchers to create knockout mice to study.
An example of this method in action can be seen through the production of a knockout mouse. This is accomplished through the administration of one or more transgenes into a fertilized mouse oocyte’s pronucleus. Afterwards, it is reimplanted into a host mother, who then births a transgenic mouse.
The International Mouse Phenotyping Consortium (IMPC) is an international scientific endeavour to create and characterize the phenotype of 20,000 knockout mouse strains. [1] [2] [3] Launched in September 2011, [1] the consortium consists of over 15 research institutes across four continents with funding provided by the NIH, European national governments and the partner institutions.
Gene knock-in originated as a slight modification of the original knockout technique developed by Martin Evans, Oliver Smithies, and Mario Capecchi.Traditionally, knock-in techniques have relied on homologous recombination to drive targeted gene replacement, although other methods using a transposon-mediated system to insert the target gene have been developed.

Mario Ramberg Capecchi (born 6 October 1937) is an Italian-born molecular geneticist and a co-awardee of the 2007 Nobel Prize in Physiology or Medicine for discovering a method to create mice in which a specific gene is turned off, known as knockout mice.

Each stem cell contains one mutant gene copy and one 'wild-type' (normal) gene copy. The entire library is intended to mutate 13,000 genes in total. Of these 13000 mutant genes, 8000 mutations in mouse ES Cells are 'targeted': that is, the mutation which knocks out gene function is inserted precisely into the genome.
