Summary Autografts of peripheral nerve or allografts of muscle basal lamina were inserted into the putamen-caudate complex of rats, with the outer end of the implant being sutured to the temporalis muscle. Elongation of central axons within the grafts, as revealed by the horseradish peroxidase retrograde labelling technique, did occur in the presence of basal lamina implants. With both types of grafting materials stained neurones exhibited a comparable distribution, being mainly found in the proximity of the central tip of the grafts. However, labelled cells in the presence of basal lamina were limited in number, compared with peripheral nerve autografts. Therefore, the usefulness of implants of muscle basal lamina into the central nervous system, in order to direct regenerating central axons toward distant target regions, is limited. This material might be suitable, as an alternative grafting material, in experimental models where avoidance of neurological impairment or size and length of the graft are crucial factors.
