| 摘要 |
The present invention relates to a method for identifying a specific type and/or state of a mammalian cell in a sample obtained from a mammal, comprising a) analyzing the relative amount of accessible chromatin in regions that are specific for a cell-type and/or cellular state in the genome of said cell, b) comparing said relative amount of accessible chromatin said in regions with the relative amount of accessible chromatin in regions in the genome of said cell that are unspecific for a cell-type and/or cellular state, and c) deducing the specific type and/or state of said mammalian cell in said sample based on said comparison. Preferably, said identifying further comprises a relative quantification of said specific cell type and/or state based on said comparison. The method can further comprise a diagnosis of a predisposition to a disease or a disease based on said identification. Kits and certain markers in regions of accessible chromatin in the genome are described, too. |
