Cellular morphogenesis is the process by which cells change shape and structure during development. This process is crucial for forming tissues and organs in multicellular organisms. It involves various mechanisms, including cell division, cell migration, and changes in cell adhesion, which help cells organize into specific patterns. During cellular morphogenesis, signaling pathways and genetic factors play significant roles in guiding these changes. For example, proteins like cadherins help cells stick together, while growth factors can influence cell behavior. Understanding cellular morphogenesis is essential for studying developmental biology and tissue engineering.
