In two separate studies, Se-Jin Lee of Johns Hopkins discovered that overproduction of follistatin and a lack of myostatin led to massive muscular hypertrophy in these organisms.
In 2006, a team led by Ellen Heber-Katz at the Wistar Institute discovered the unusual regenerative abilities of the Murphy Roths Large strain of this organism.

Capecchi, Evans, and Smithies won the 2007 Nobel for a technique in which junk DNA is introduced to the genomes of these organisms to (*) displace an existing gene, while another type has been engineered to carry activated oncogenes. Notable examples of this organism include the immuno-compromised, thymus-lacking "nude" variety, as well as the "knockout" type. Charles Cavanti seeded human cartilage cells into a biodegradable mold on the back of one of these organisms in 1995, prompting an outcry from ignorant animal rights activists because it looked like an ear. For 10 points, identify this most common mammalian model organism, a rodent and member of the genus Mus.
