Some of these digits develop completely from cells that have the ability to produce and respond to secreted SHH. This type of signaling is what? Direct contact Paracrine Endocrine Synaptic Autocrine

Solution

Answer: B Paracrine

Paracrine signaling is a form of cell to cell communication in which a cell produces a signal to induce changes in near by cells by altering the behavior differentiation of certain cells. Sonic hedgehog is a protein is known to be involved in embryonic development of digits on limbs and organization of the brain.
