Prostaglandins guard stem cells by increasing the production of an inhibitory factor in the mesenchymal bone marrow cells. Mesenchymal cells are marked with a green protein (left); the inhibitory factor is red (center). Combined image (right): Treatment with prostaglandins (bottom) increases the secretion of the inhibitory factor
