Talk:Mouse Timeline Detailed
From Embryology
Taste Development
Timeline of mouse morphological development in the taste system.
| Gustatory ganglion | Placode formation | Placode delamination migration | Initial axon outgrowth | Peak cell production | Axons reach tongue | Peak cell death | Target innervation |
|---|---|---|---|---|---|---|---|
| E8.5 | E9.5 | E9.5 | E10.5 | E12 | E14.5 | E14-15 | |
| Tongue and taste buds | Tongue | Fungiform papillae (placode) (SEM) | Full no. of fungiform papillae | Taste bud differentiation begins | Taste pores | Full no. of vallate taste buds | |
| E12 | E13-13.5 | E14.5 | E16.5 | postnatal | adult | ||
A general timetable of major morphological changes is provided for rats and mice. The first sperm/plug positive day is considered day 0.5. Mice typically develop two days earlier than rats. The bold time points have been determined experimentally, non-bold numbers are estimated values based on this two-day difference.
