If the cells are part of the same organism, then no, they don't contain different genes. This is a common misconception - although the two cells have very different functions, they have the exact same DNA. The difference is due to the way the DNA is transcribed and translated. Genes that function as enzymes in the liver will be present in the DNA of a kidney cell, but it won't be expressed into the polypeptide.
There are a variety of factors that may "turn off" a gene, some of which include histone acetylation and DNA methylation. If nucleosomes in a chromosome are not acetylated, then they will be more condensed into one area. This in turn may block the RNA polymerase from attaching to a promoter sequence and transcribing the gene. Similarly, methyl groups can bond to the gene, blocking RNA polymerase. This ensures that genes that usually function in different organs aren't expressed.

Do different cells have different genes?
If the cells are from one individual, all will have the same genes except their sex cells which have 1/2 the number. A dog will have different genes from a cat. The genes make the cat different from the dog and human.
For what molecule do genes contain the intructions for building?
Different genes contain the information to construct different proteins which lead to the formation of different cell type and thus the organism.
Do all body cells activate the same genes?
All body cells have the same genes except for the sex cells (sperm and ova). They do not use the same genes. A muscle cell isn't using the same genes as a nerve cell does. Otherwise the muscle cell and the nerve cell would not be different nor do different things.
What are the viral genes for?
to produce copies of the virus once inside the host cell
Why do different genes have a different molecular clock rate according to the neutral theory of molecular evolution?
Different genes have different molecular clock rates due to the amount of Cytoplasmic Dyruduemion the genes contain. The more Cytoplasmic Dyruduemion the genes have, the slower the molecular clock rate, according to the neutral theory of molecular evolution.
What do egg cells usually contain?
genes
Do different cells have different genes?

What do chromosomes contain that control the characteristic of the cells?
genes
Does a cheek cell contain the same chromosomes as a liver cell?
Yes. In an individual, almost all cells contain DNA (Red Blood Cells do not). That DNA is tightly wound like you would twist a drawstring, and kept tightly coiled as chromosomes. Since chromosomes can be found in a cheek cell, a liver cell (hepatocyte), and almost all other cells, they all contain the same chromosomes, which inevitably have the same genes. What makes cheek cells different from liver cells is which genes are turned on and off. Cheek cells have different genes turned on compared to liver cells.
Does a cell in your stomach contain genes for brain cells?
yes
Do body cells contain a complete set of genes?
Yes, they do.
What are threadlike structures in nucleus of cells that contain genes?
DNA, deoxyribonucleic acid, is the structure that contains the genes.
For what molecule do genes contain the intructions for building?
Different genes contain the information to construct different proteins which lead to the formation of different cell type and thus the organism.
What causes the differences between two human cell types?
contain same genes, but uses different combinations of them.
Do all body cells activate the same genes?

Do tumor viruses contain genes found in normal cells?
help idont Know?
Do different kinds of cells in an embryo have different sets of genes?
No. With the odd exception (eg. mature red blood cells because they have no nucleus) every cell in a multicellular organism has the same set of genes. What gives the cells their different character, their phenotype, is which of these genes are expressed at any given time.
