Formation of cardiac muscle cells by using 3-D folding of DNA

The 3-D folding of the DNA restructures itself during the differentiation of pluripotent stem cells to cardiomyocytes. This restructuring of the DNA architecture introduces and defines important epigenetic patterns. At the University of Freiburg in the Department of Experimental and Clinical Pharmacology and Toxicology headed by way of Prof. Dr. Lutz Hein, a group lead with the aid of personal lecturer Dr. Ralf Gilsbach, who conduct research have come to this conclusion. The consequences endorse that the genome's spatial organization is an vital change for defining cell types, thereby representing a very promising beginning point for future reprogramming strategies. The genome stores data about an organisms development. The epigenome is crucial for determining cellular identity because every cell type in a mammalian organism requires access to genomic areas in a tempo-spatial specific manner. Various epigenetic mechanisms are associated with cell differentiation as it is already known.

Modern studies also show that differentiation processes are accompanied by a reorganization of the 3-D folding of the DNA. A team made it viable to map the third-dimensional genome organization as well as epigenetic mechanisms throughout the differentiation of cardiomyocytes across the whole genome. For this purpose, the researchers set up techniques for setting apart cardiomyocytes in a variety ofdevelopmental stages from healthy mouse hearts. This cell-type-specific evaluation was fundamental to demonstrate that there is a close interplay between epigenetic mechanisms and the spatial folding of the DNA in the cardiomyocytes' nucleus. The type of spatial folding of DNA defines which genes are activated and which methylation patterns are formed. The spatial arrangement of the DNA is not dependent on the DNA methylation with cells and amoung other things that have no DNA methylation at all. The 3-D genome organization is thus a central switchboard for determining cellular identity.
