Regulation of X chromosome inactivation in development in mice and humans.
Since each stem cell located in the basal layer of epidermis or hair follicle would give rise to a clone of progeny cells that would populate an intraepidermal column, we reasoned that the width of this clonally derived column could be determined by obtaining samples of increasing diameter and examining the DNA for the presence of a maternal versus paternal pattern of X chromosome inactivation.
To verify the HUMARA methodology, DNA isolated from a basal cell carcinoma was analyzed and observed to yield a clonal pattern of X chromosome inactivation by comparing tumor DNA before and after HpaII digestion.
