Post embryonic development refers to the process by which an organism develops mature structures from the completion of embryonic development. Post embryonic development typically involves a series of procedures such as the growth and maintenance of adult form. Furthermore, it is noteworthy that in some organisms, the appearance of adult characteristics is closely linked to changes in programs as well as genes during embryonic development.

Postembryonic development involves multiple changes, such as regeneration and aging. Normally, animals continue to develop after birth. When animals are injured, they can regenerate specific tissues. Aging is the most common phenomenon and is mainly determined by genes. In addition, nutrition is also a crucial factor affecting post embryonic development.
In organisms, changes at different stages of the life cycle may lead to altered characteristics in adulthood. In recent years, research on the mechanisms of postembryonic development has gradually received widespread attention. The advent of a series of scientific technologies such as sequencing and genetic engineering has promoted this process. Importantly, studies of postembryonic development also provide new perspectives for a comprehensive understanding of developmental diversity.
The formation of a unique organism from a single cell is an amazing process, which is closely related to the activity of multiple signaling pathways. In fact, several signaling pathways play an integral role in this process. Therefore, understanding these signaling pathways contributes to exploring the basic mechanisms of biological development.
RA signaling plays a vital role in the development of humans. Currently, RA signaling is shown to have a positive impact on regenerated limb length. Furthermore, this signaling is closely linked to the patterning of regenerated limbs. Treatment of regenerated limbs with exogenous RA effectively promotes bone elongation.
This signaling pathway participates in the control of cell polarity, cell movement, and migration. WNT/β-catenin signaling is also essential for development and diseases, especially in cancers.
This pathway is closely linked to the maintenance of adult homeostasis, such as stem cell maintenance. This signaling allows components to be reset, allowing the cell to become competent again. Therefore, this pathway is also essential for the development of the organism.
