Radiation-Induced Dermatitis Model
Radiation-induced dermatitis is a common and distressing side effect of radiation therapy, affecting nearly 90% of patients. This condition manifests as moderate-to-severe skin reactions, significantly diminishing the quality of life and potentially complicating the treatment process. Radiation not only damages the skin surface but also affects deeper tissues, leading to symptoms such as dryness, loss of elasticity, pigmentation changes, soft tissue fibrosis, capillary dilatation, and dermatitis in the treated areas. Furthermore, it causes irreversible damage to the microvascular network and endothelial cells of small blood vessels in the skin, resulting in prolonged healing times and increased susceptibility to infections.

To address these challenges, Creative Bioarray has developed the Radiation-Induced Dermatitis Model. This innovative model is designed to simulate the complex skin reactions triggered by radiation therapy, providing a critical tool for evaluating the efficacy of new therapeutic compounds aimed at alleviating these common side effects. By leveraging this model, researchers can gain deeper insights into the mechanisms of radiation-induced skin damage and accelerate the development of effective treatments to improve the quality of life for cancer patients undergoing radiation therapy.
