If I were a developmental biologist…

1. I would like to learn more about how chromatin modifications affecting gene expression are passed on through cell lineages, thus maintaining proper gene expression (e.g. through cell lineages in the same tissue). I would like to learn which proteins are used to modify histones, and the process through which that occurs.

2. If we could learn more about these, it could potentially help us learn how to reverse this pattern of gene repression and create cells that could possibly differentiate into more types of cells.
