- ‘The population has experienced an expansion from a few copies in the single germ cell, and a distribution skewed toward more molecules having several mutations may be expected.’
- ‘Male identity would be a cell-autonomous decision entirely independent of the sexual identity of the soma but dependent upon the number of X chromosomes in the germ cell.’
- ‘A mature male or female germ cell usually possessing a haploid chromosome set is capable of initiating formation of a new diploid individual by fusion with a gamete of the opposite sex.’
- ‘A majority of the strains examined contained one insertion and the highest number of insertions that occurred in a single germ cell was seven.’
- 1.1 An embryonic cell with the potential of developing into a gamete.
- ‘Of all the stem cells that we use in research, they come from three sources: embryonic stem cells, embryonic germ cells and adult stem cells.’
- ‘Researchers discovered that they could develop primordial germ cells from embryonic stem cells.’
- ‘In order to create sperm, the scientists first had to make embryonic germ cells, that in itself a major achievement.’
- ‘These types of moles are produced by the development of a germ cell that lacks equal contributions of DNA from both the egg and the sperm.’
- ‘The follicle is composed of the germ cell, the oocyte, and surrounding follicle cells that originate from the epithelial cells of the germinal epithelium.’
