A comparison between real-time quantitative PCR and DNA hybridization for quantitation of male DNA following myoblast transplantation.
The transplantation of muscle precursor cells (myoblasts) is a potential therapy for Duchenne muscular dystrophy. A commonly used method to detect cell survival is quantitation of the Y chromosome following transplantation of male donor cells into female hosts. This article presents a direct comparison between real-time quantitative PCR (Q-PCR) and the DNA hybridization (slot-blot) technique for quantitation of Y chromosome DNA. Q-PCR has a significantly greater linear quantitation range and is up to 40-fold more sensitive at low concentrations of male DNA, detecting as little as 1 ng of male DNA in each female tibialis anterior (TA) muscle. At high male DNA concentrations, accurate quantitation by Q-PCR is 2.5 times higher than the maximum possible with slot-blot. In conclusion, Q-PCR has a higher dynamic range and is more efficient than slot-blot analysis for the detection of donor cell engraftment in a transsexual transplantation model.
