The tumor microenvironment (TME) in pediatric cancers is profoundly shaped by the unique biological 18 context of childhood development. Unlike adult tumors, pediatric malignancies arise in growing 19 tissues, where evolving immune systems, dynamic stromal elements, and distinct hormonal and 20 microbial influences converge to create highly specialized tumor-supportive niches. This review 21 explores how developmental processes interact with tumor biology to drive immune evasion, therapy 22 resistance, and disease progression. Key mechanisms such as extracellular matrix remodeling, 23 metabolic reprogramming, and epigenetic plasticity are highlighted as critical contributors to treatment 24 failure. Also, the recent advancements in nanomedicine, circulating markers makes it possible for 25 interventions to be more precise and age-informed. The integration of developmental biology along 26 with tumor ecosystem can emphasis the necessity of developing treatment plans that take into account 27 risks and advantages associated with pediatric TME.
