Discussion Following the Report of Prof. Miyake
I have a comment which is related to the terminology regarding restitution and the protection of the proliferative zone. The process of restitution can occur, as you have pointed out, within 10–30 min — very rapidly, far more rapidly than cells can actually turn over. These cells do not necessarily come from the proliferative zone. Rapid restitution is not cell proliferation; it is cell migration.
