Novel Assay to Probe the DNA Methylation State of Multiple Genomic Loci in Single Cells
The scientists from A*STAR’s Institute of Medical Biology (IMB) and Institute of Molecular and Cell Biology (IMCB) developed a novel methodology to probe single cells for various DNA-methylation errors at multiple loci to reveal failed maintenance of epigenetic mark results in chimeric mice, which display unpredictable phenotypes leading to developmental arrest. This methodology allows the use of a special technique utilizing a microfluidic device to safely extract one cell for performing the assay called “pronuclear transfer” to ameliorate reprogramming defects in embryos.
