Regrowing the optic nerve (IMAGE) Boston Children's Hospital Caption Rats whose retinas were treated with slow-release beads containing oncomodulin (plus a cofactor that boosts cells’ response to oncomodulin) showed dramatically increased growth of axons into the optic nerve (bottom panel) as compared with controls who received empty beads (top panel). The asterisk indicates the injury site. Credit Courtesy Larry Benowitz, PhD.
