<qa>  What is the main reason for the lack of ethical conflict?The human induced pluripotent stem cells hiPSCs represent a prime candidate cell type for current research and future cell therapy because of their significant self-renewal, differentiation potential and the relative lack of ethical conflict. With the advent of efficient technology of reprogramming peripheral blood mononuclear cells PBMCs into hiPSCs, researchers can generate personalized lines of cells from which it will be possible to obtain differentiated cells in a less invasive way, introducing opportunities in treating diseases that are now considered incurable.
