Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
52 words
A method of providing a cell culture comprising (1) providing a transgenic non-human mammal, all of whose germ cells and somatic cells contain a recombinant activated oncogene sequence introduced into said mammal, or an ancestor of said mammal, at an embryonic stage; and (2) culturing one or more of said somatic cells.
Claim 2
Independent Claim
52 words
A method of providing a cell culture comprising (1) providing a transgenic non-human mammal, all of whose germ cells and somatic cells contain a recombinant activated oncogene sequence introduced into said mammal, or an ancestor of said mammal, at an embryonic stage; and (2) culturing one or more of said somatic cells.
Claim 3
Dependent Claim
49 words
A cell derived from a somatic cell obtained from a transgenic non-human mammal, all of whose germ cells and somatic cells contain a recombinant activated oncogene sequence introduced into said mammal, or an ancestor of said mammal, at an embryonic stage which cell contains said recombinant activated oncogene sequence.
Claim 4
Dependent Claim
49 words
A cell derived from a somatic cell obtained from a transgenic non-human mammal, all of whose germ cells and somatic cells contain a recombinant activated oncogene sequence introduced into said mammal, or an ancestor of said mammal, at an embryonic stage which cell contains said recombinant activated oncogene sequence.
