The main goal of HESC research is to identify the mechanisms that govern cell differentiation and to turn HESCs into specific cell types that can be used for treating debilitating and life-threatening diseases and injuries. A typical day-5 human embryo consists of 200–250 cells, most of which comprise the trophoblast, which is the outermost layer of the blastocyst.That is, if the zygote, A, divides into two genetically identical cell groups that give rise to identical twins B and C, B and C cannot be the same individual as A because they are not numerically identical with each other.This shows that not all persons can correctly assert that they began their life as a zygote.We share our knowledge and peer-reveiwed research papers with libraries, scientific and engineering societies, and also work with corporate R&D departments and government entities.Human embryonic stem cell (HESC) research offers much hope for alleviating the human suffering brought on by the ravages of disease and injury.At this stage, human embryos are said to be “whole living member[s] of the species homo sapiens …[which] possess the epigenetic primordia for self-directed growth into adulthood, with their determinateness and identity fully intact” (George & Gomez-Lobo 2002, 258).The issue of when a human being begins to exist is, however, a contested one.The standard view of those who oppose HESC research is that a human being begins to exist with the emergence of the one-cell zygote at fertilization.While each of the cells is alive, they only become parts of a human organism when there is substantial cell differentiation and coordination, which occurs around day-16 after fertilization.Thus, on this account, disaggregating the cells of the 5-day embryo to derive HESCs does not entail the destruction of a human being.
