| These cells, usually seen as being mesodermal, apparently represent another cell line originating from endoderm. |
| The adrenal cortex is of mesodermal origin, whereas the adrenal medulla is derived from the neural crest. |
| However, some lesions are amelanotic and others demonstrate features similar to other malignant neoplasms of ectodermal, mesodermal, or hemopoietic origin. |
| It is characterized by induction of the mesodermal layer and by commitment of cell movements. |
| This emphasis on complexity has lead to delineations within the metazoans based on mesodermal features. |
| This mode of establishing the mesodermal musculature likely has occurred in small vermiform organisms. |
