Scientists from The Hebrew University of Jerusalem, Columbia University Medical Center (CUMC) and The New York Stem Cell Foundation Research Institute (NYSCF) have succeeded in generating a new type of embryonic stem cell that carries a single copy of the human genome, instead of the two copies typically found in normal stem cells.
The researchers showed that these haploid stem cells were pluripotent—meaning they were able to differentiate into many other cell types, including nerve, heart, and pancreatic cells—while retaining a single set of chromosomes.
