Preparing Map of Chromosome Territory Distribution Frequency.

The chromosomes in mammalian interphase nuclei are organized into domains called chromosome territories that play a major role in nuclear organization. Here we propose a methodology that combines the use of micro-patterning of adhesive molecules to impose single-cell geometry, with visualization of chromosome territories. This allows obtaining a representative statistical map of the absolute positions of chromosome territories relative to the geometry imposed to the cell population by combining the signal from each cell.
