New Rochelle, NY, August 19, 2019-Although the literature describes the mammalian zygote as a totipotent cell, one researcher challenges this view and has proposed a revised alternative model of mammalian cellular totipotency. The basis for this new model and its implications and potential applications are presented in an article published in Stem Cells and Development, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

“On Mammalian Totipotency – What Is the Molecular Underpinning for the Totipotency of a Zygote?” is the work of Kejin Hu, PhD, University of Alabama at Birmingham. Dr. Hu explores the concept of a totipotency – the ability of a stem cell to give rise to any cell type or a blastomere to form a complete embryo – from a molecular perspective. He defines three main aspects of totipotency: genetic, epigenetic, and biochemical (the capacity to be reprogrammed to epigenetic totipotency). While a zygote is genetically totipotent, it is not epigenetically totipotent. It does, however, have the capacity for reprogramming to a totipotent state. Based on these conclusions, Dr. Hu developed his revised model for the capacity for cellular totipotency.

Stem Cells and Development values a continuing and evolving discourse on this fascinating and contentious topic,” says Editor-in-Chief Graham C. Parker, PhD, The Carman and Ann Adams Department of Pediatrics, Wayne State University School of Medicine, Detroit, MI.
