Dampened X-chromosomes in human pluripotent stem cells: dampening or erasure of X-upregulation?
The recent report of X-chromosome dampening in human preimplantation embryos remains controversial. Subsequently, Sahakyan et al. found evidence of X-chromosome dampening in human naïve pluripotent stem cells (hPSCs) as well. Here, we discuss whether X-dampening reported in hPSCs truly reflects the dampening of X-chromosomes or it is a consequence of the erasure of X-chromosome upregulation.
期刊介绍:
Chromosoma publishes research and review articles on the functional organization of the eukaryotic cell nucleus, with a particular emphasis on the structure and dynamics of chromatin and chromosomes; the expression and replication of genomes; genome organization and evolution; the segregation of genomes during meiosis and mitosis; the function and dynamics of subnuclear compartments; the nuclear envelope and nucleocytoplasmic interactions, and more.
The scope of Chromosoma encompasses genetic, biophysical, molecular and cell biological studies.
