Human Proteome Project and Human Pluripotent Stem Cells: Odd Bedfellows or a Perfect Match?

The Chromosome-Centric Human Proteome Project (C-HPP) aims at the identification of missing proteins (MPs) and the functional characterization of functionally unannotated PE1 (uPE1) proteins. A major challenge in addressing this goal is that many human proteins and MPs are silent in adult cells. A promising approach to overcome such challenge is to exploit the advantage of novel tools such as pluripotent stem cells (PSCs), which are capable of differentiation into three embryonic germ layers, namely, the endoderm, mesoderm, and ectoderm.
