[The isolated perfused Bovine Udder Skin]

Area of Science:

• Dermatology
• Toxicology
• Pharmacology

Background:

• The Bovine Udder Skin (BUS) model is an ex vivo skin model derived from slaughterhouse material.
• It can be maintained in culture at high vitality for at least 8 hours.
• BUS skin morphology closely resembles human skin, more so than rodent skin.

Purpose of the Study:

• To evaluate the utility of the BUS model for studying skin penetration, absorption, and irritation.
• To assess the correlation of BUS model data with human in vivo data for pharmacological and toxicological studies.
• To highlight the potential of the BUS model in reducing animal testing and providing unique pharmacokinetic and drug metabolism insights.

Main Methods:

• Utilizing isolated perfused Bovine Udder Skin (BUS) from slaughterhouse material.
• Maintaining the BUS model in culture for extended periods (at least 8 hours).
• Conducting pharmacological and toxicological assessments on raw materials and formulated products.

Main Results:

• The BUS model demonstrates high vitality and can be maintained for over 8 hours.
• It allows for the study of skin penetration, absorption, and irritation under near in vivo conditions.
• Studies show a high correlation between BUS model data and human data for cosmetic and skin products.

Conclusions:

• The BUS model is a promising tool for skin research, offering a valuable alternative to animal testing.
• Its morphological similarity to human skin and high correlation with human data make it suitable for cosmetic and pharmaceutical applications.
• The BUS model provides unique data, including pharmacokinetics and drug metabolism, not obtainable through other in vitro methods or human studies.
