Loss of intestinal goblet cells causes fatal disease after stem cell transplantation
Allogeneic stem cell transplantation can cause a loss of protective goblet cells from the colon’s inner lining, which can be fatal. But boosting those cells beforehand could improve the outcome. A significant loss of the colon cells following a stem…
