Abstract: | The development of the brachial spinal cord was studied in the marsupial Macropus eugenii (tammar wallaby) on postnatal days 1-34. On day 1 the spinal cord was histologically immature, with a deep central canal, proliferating neuroepithelium and roof and floor plates. The lateral motor column had formed, and forelimb muscles contained primary myotubes. The spinal cord gradually attained a mature appearance between days 1-34. The results confirm the suitability of the wallaby spinal cord for studies of early mammalian development. |
