Limb Development
Limb development is an important process during fetal development that produces the limbs of the human body. The limbs develop from limb buds, which are located at the edges of the developing embryo. Growth factors, hormones, and other complex signals work together to coordinate the morphogenesis of the limb buds, ultimately resulting in the formation of the five distinct segments of each limb: shoulder/arm, forearm, wrist, hand, and finger or thigh, lower leg, ankle, foot, and toe. Defects that occur during limb development can have serious long-term implications for the health and function of an individual. Consequently, research into limb development continues to be a priority in developmental biology and medicine, with the aim to improve our understanding of the genetic and environmental factors that contribute to development and to identify potential novel treatments for limb malformations.
