Embryonic chick ciliary ganglion x30

In the eye, non-motile cilia are found inside the light-sensitive cells (photoreceptors) of the retina. These cilia act like microscopic train-tracks, and allow the transport of vital molecules from one end of the photoreceptor to the other.

Cilia is an organelle (hair-like organ in its simplest form). Every cell has them. Lungs, kidneys, optical nerve, etc. have them. They are everywhere. Ganglion simply means a network/mass of cilia for a specific function. Chick embryotic cilia is just that. Cilia extracted/cut out of a embryonic stem cell (not any cell) and given conditions where it can grow (in a petri dish) but it dies fairly soon after that. If they could make it survive, the hope is; they could do the transplant say inside the retina and restore person's sight. Lot of research, not much success

Striking!

Isn't life amazing! 1fd
