MicroRNA (miR-34a)

Caption

Duke scientists grew two sets of cellular "miniguts" on culture dishes and stimulated them with inflammatory factors. The miniguts on the left are normal. But on the right, the deletion of a MicroRNA called miR-34a causes stem cells (green markers in the top right image and red markers in the bottom right image) to divide out of control. This causes the minigut to bloat into a cancerous sphere.
