| 11. | There are two layers of mesoderm; intraembryonic and extraembryonic.
|
| 12. | Nephric mesenchyme separates from the intermediate mesoderm as a single elongated primordia.
|
| 13. | In most cases, a mesoderm also develops between them.
|
| 14. | The nephrogenic cords are bilateral condensations of the intermediate mesoderm.
|
| 15. | Brachyury is an essential transcription factor required for mesoderm formation.
|
| 16. | The AER expresses FGF8 which induces Shh expression in the posterior mesoderm.
|
| 17. | Ingression of these cells results in formation of the mesoderm.
|
| 18. | Mixl1 plays a role in mesoderm patterning and tissue specification at gastrulation.
|
| 19. | Mixl1 expression is required for both mesoderm development and hematopoiesis.
|
| 20. | Minot found these cells in the context of histological studies of mesoderm.
