Promotion of regeneration and axon growth following injury in an invertebrate nervous system by the use of three-dimensional collagen gels

BY SUSANNA E. BLACKSHAW, SCOTT ARKISON, CLAIRE CAMERON AND JANE A. DAVIES

On pages 658-660, figures 1, 2 and 4 should have appeared with their respective scale bars and lettering (see below and overleaf).

Figure 1. Migration of cells into the gel matrix from the cut ends of connectives of leech ventral nerve cord. Two leech ganglia with shortened connectives were apposed within the gel. Migration of cells appears to be directed towards the apposing cut end. Four-day-old culture. Scale bar: 100 urn.

Figure 2. Typical examples of nerve fibre outgrowth into the gel. (a) Outgrowth of connective axons, 6-day-old culture. (b) Fasciculation of axons regenerating into the gel from the cut end of connectives after 12 days of culture. (c) Co-culture of ganglion with target tissue after 6 days of culture. Outgrowth from the cut end of connectives (c) is directed towards, and appears to make contact with, the cut end of the nerve root (n) of a second ganglion. (d) Neurite outgrowth (*) from the cut ends of axons (minus their cell bodies) within a piece of connective. Three-day- old culture. Rhodamine-phalloidin staining also shows the muscle fibres within the connective sheath that run the length of the nerve cord. Scale bar: 50 gm.
