The process, occurring in the embryo, by which the anatomical structures of the hindlimbs are generated and organized. The hindlimbs are the posterior limbs of an animal. [ISBN:0198612001]
Embryonic hindlimb morphogenesis is a complex and tightly regulated process that involves the coordinated action of numerous signaling pathways, transcription factors, and cell-cell interactions. It begins with the specification of the hindlimb field, a region of the embryonic mesoderm that is destined to give rise to the hindlimbs. This specification is controlled by a combination of inductive signals from the surrounding tissues, including the notochord, the somites, and the lateral plate mesoderm. Once the hindlimb field is established, it undergoes a series of morphogenetic movements, including outgrowth, patterning, and differentiation, which ultimately result in the formation of a fully developed hindlimb. Outgrowth is driven by the proliferation and migration of mesenchymal cells, which form the core of the limb bud. The limb bud is also patterned along its proximodistal (shoulder to fingertip), anteroposterior (thumb to little finger), and dorsoventral (back to palm) axes. This patterning is regulated by a complex interplay of signaling molecules, including fibroblast growth factors (FGFs), Wnt proteins, and retinoic acid. These signaling molecules interact with each other and with transcription factors to establish distinct domains within the limb bud that are destined to give rise to different skeletal elements, muscles, and connective tissues. Differentiation occurs as cells in the limb bud become committed to specific fates and begin to express the genes that are required for their development. This process is influenced by a variety of factors, including the expression of specific transcription factors, the interaction of cells with their surrounding environment, and the availability of nutrients. For example, the expression of the transcription factor Shh in the zone of polarizing activity (ZPA) at the posterior margin of the limb bud is essential for the development of digits, while the expression of the transcription factor Tbx5 in the anterior limb bud is required for the development of the humerus. The formation of the hindlimb is a highly coordinated process that requires precise temporal and spatial regulation of a diverse array of genes and signaling pathways. Dysregulation of these processes can lead to a variety of birth defects, such as limb deficiencies and polydactyly.'
