Skin Irritation

Wound Healing

BioLegacy provides definitive, quantitative assessments of a therapeutic’s ability to accelerate the complex cascade of tissue repair. We leverage a comprehensive, multi-species platform of well-characterized dermal wound models. Our expertise in systems from diabetic ulcer models to deep wound evaluation in translational large animal species allows for a robust characterization of your compound or device’s impact on re-epithelialization, granulation tissue formation, and wound tensile strength.

  • Dermal Wound Healing: Multi-species (Rat, Mouse, Mini-pig, Rabbit) excisional and incisional models to assess wound closure kinetics and tissue regeneration.
  • db/db Mouse Dermal Wound Model: The gold-standard model of impaired healing in a diabetic context, essential for testing therapeutics targeting diabetic foot ulcers.
  • Full-Thickness Dermal Wound Healing in Rabbit: Evaluate wound contraction and the histopathological quality of the repaired tissue.
  • Long-Term Deep Wounds model in Mini-pig: The most translationally relevant model for assessing therapies on deep, long-term wounds due to physiological similarity between porcine and human skin.

Dermatitis & Psoriasis

Understanding a therapeutic’s ability to impact complex skin diseases like dermatitis and psoriasis requires careful examination of distinct immune pathways. BioLegacy provides definitive assessments of immunomodulatory effects using a comprehensive suite of highly translatable in vivo models. Our expertise in platforms ranging from classic hapten-induced dermatitis to sophisticated human skin engraftment models allows for a robust characterization of your compound’s impact on epidermal hyperplasia, inflammatory infiltrates, and key cytokine axes, giving you a key understanding of its clinical potential.

  • DNFB-Induced Dermatitis (Mice, Pigs): A classic DTH model of contact hypersensitivity to evaluate the efficacy of both topical and systemic anti-inflammatory agents.
  • Human Psoriatic Skin Engraftment: A sophisticated humanized model that allows for the direct evaluation of a therapeutic's effect on human psoriatic tissue in vivo.
  • IL-12/LPS-Induced Psoriasis in SCID Mice: A rapid, cytokine-driven model that recapitulates key Th1-mediated pathological features of psoriasis.
  • Patch Application Models: Specialized study designs for assessing the local tolerance, delivery, and efficacy of transdermal patch-based therapeutics.

Skin Irritation

A quantitative characterization of a compound’s potential for dermal irritation is a critical safety checkpoint for any topical therapeutic or compound with dermal exposure risk. BioLegacy provides this definitive local tolerance assessment using robust, validated in vivo models that adhere to global regulatory guidelines. Our expertise in systematic scoring of erythema, edema, and other clinical signs ensures the generation of a clear, unambiguous data package to define your compound’s irritation profile and support its safe progression to the clinic.

  • Modified Draize Scoring for Dermal Irritation: Standardized, semi-quantitative scoring to objectively assess the severity of dermal reactions such as erythema and edema, providing essential local tolerance data in rodent and non-rodent species.
