Sentences with phrase «patterns on a cell type»

Not exact matches

In the clearest possible case, the ANT - OAR cell would differ from a zygote on all of the parameters noted above: The ANT - OAR cell would have a pattern of gene expression that is clearly distinct from a zygote; it would generate a homogeneous population of cells rather than multiple cell types; it would undergo simple cleavage divisions and not produce any multicellular structures.

Typically, cells of the same type have matching patterns of gene activity — many of the same genes are turned off or on in all cells.

Surprisingly, they found that although the patterns of gene expression — as shown by the RNA sequencing — differed between the hepatocellular carcinomas and the liver cancers with biliary phenotype and depended on the histological type, the overall pattern of mutations in the cells was actually similar between the tumors — of either type — that had emerged in patients who had had infections with either hepatitis C or B, and were different in patients without such infections.

«We generate a pattern of an organ that we want, creating a 3D hollowed - out structure, stick it on a piece of glass, then we can introduce a lot of different cell types,» Gillrie says.

They found that carcinoma cells from smokers carried the «transcriptional fingerprint» (i.e. the pattern of genes that were switched on or off) of basal cells, suggesting that the tumors may originate from this type of cell.

«Cell - type — based model explaining coexpression patterns of genes in the brain» appears online in PNAS on March 24, 2014.

Depending on the composition of the viral envelope, viruses exhibit particular patterns of cell tropism, and thus are suited for infecting specific cell types.

The resulting DNA copy number variation and patterns of chromosome loss and gain are tumor - type specific, suggesting differential selective pressures on the two tumor cell types.

During development, genes within specific cell types are turned on and off to trigger the necessary expression patterns that create a whole animal.
