Table 1. A sampling of literature with references to functional PGCC using varied terminology.

The presence of polynuclear cells with pluripotent and malignant potential have been reported for many years, yet a cohesive field of shared terminology is only beginning to appear. These references represent some of the papers that form a large but sporadic body of work that underlies the emerging PGCC field.
