Figure 1. Fluidity of cellular identity, in vivo and in vitro.

Cellular identity is the sum of a cell’s epigenetic landscape. It can become altered through numerous in vivo processes including development, metaplasia, and dysplasia. It can also be manipulated by experimenters in protocols such as directed differentiation, transdifferentiation, and reprogramming.
