Biological, Cellular, And Molecular Characteristics Of An Inducible Transgenic Skin Tumor Model: A Review

This review highlights that genetically engineered mouse models are valuable for studying melanoma development and progression by mimicking human skin biology, revealing key signaling pathways and molecular mechanisms that contribute to melanoma heterogeneity and offering insights into potential therapeutic targets.

This study found that transgenic mice expressing IGF-1 in their skin showed significant skin changes, early hair follicle generation, and a higher propensity to develop tumors after chemical promotion, suggesting IGF-1's role in skin carcinogenesis.

This study found that chemically induced skin tumors in mice predominantly originated from Lgr6 + and/or Lrig1 + stem cells of the upper hair follicle rather than from other stem cell populations.

This study standardized a reproducible three-dimensional human skin model for testing skin tumor promoters, using methods that do not require human skin sourcing.

This study found that human skin grafted onto certain immunodeficient mice resulted in proliferative scars with characteristics similar to human hypertrophic scars, suggesting these models may better represent the condition's natural history.
