Question

Taste receptors in the tongue are replenished periodically, presumably from a stem-cell niche residing in the tongue itself. For an image of the organization of taste receptors in the tongue. Both FGF and Wnt signaling are known to be important for the pattern of where some types of taste receptors are positioned in the tongue. develop a hypothesis that explains how this might occur and how a niche for taste receptors might be regulated. Then, propose experimental approaches to test your hypothesis.

Explanation / Answer

There are several types of gustatory receptor found in tongue. This receptor might replenished periodically from stem cell niche centre present in tongue.

In receptor formation from stem cell fgf and wnt signalling helps in its response.

Niche for taste receptor regulated by stem cell present in tongue by their differentiation. When the taste receptor get damaged the niche cell undergoes differentiation when they get some signals.
