Sonic Hedgehog protein

The Sonic Hedgehog (Shh) protein is a signaling molecule crucial for proper development in the body. It helps direct cells to grow, divide, and specialize into different tissues during embryonic development, especially in the brain, limbs, and organs. Shh acts like a messenger, transmitting information between cells to ensure they develop in the correct place and form functional structures. Disruptions in Shh signaling can lead to developmental abnormalities or diseases such as cancer. Overall, Sonic Hedgehog plays a vital role in shaping the body's structure and function during early growth.
