Shh (Sonic Hedgehog)

Sonic Hedgehog (Shh) is a protein that plays a crucial role in early development, guiding how cells grow, divide, and form different parts of the body. It acts like a signaling molecule, providing instructions to cells about their location and function, especially in the formation of organs and limbs. Proper Shh activity ensures normal development, while abnormalities can lead to birth defects or diseases like cancer. Essentially, Shh is like a communication messenger, helping the body's cells coordinate during critical stages of growth.
