Stimulation of spermatogonial DNA synthesis in slug gonad by a factor released from cerebral ganglia under the influence of long days

Incorporation of [ 3H]thymidine into gonadal DNA was shown to increase 1 week after implantation into an immature slug ( Limax maximus) of a “brain” (circumesophageal ring of ganglia) from a male-phase donor. Light microscope autoradiography revealed that in stimulated gonads labeling was localized...
