Cell growth and differentiation

Cell growth and differentiation refers to the coordinated biological processes through which cells increase in mass and acquire specialized structural and functional features (NCBI, 2002). Cell growth is typically regulated by the cell cycle and nutrient-sensing pathways like mTOR, which ensure that cells divide only in response to appropriate physiological signals. Differentiation is the process by which stem or progenitor cells mature into specific lineages, driven by complex gene regulatory networks and epigenetic modifications (Nature, 2023). These mechanisms are essential for embryonic development, wound healing, and the maintenance of tissue homeostasis in adult organisms. Dysregulation of these processes is a hallmark of many diseases, most notably cancer, where cells lose differentiation markers and gain uncontrolled proliferative capacity (PubMed, 2021). Although many therapeutic agents target specific molecules within these pathways—such as growth factor receptors or kinases—the term "cell growth and differentiation" describes a physiological outcome rather than a discrete molecular target.
