We studied the inhibitory effects of 4-hydroxyphenyl á-glucopyranoside (á-arbutin) on melanogenesis in cultured human melanoma cells, HMV-II, and in a three-dimensional cultured human skin model. á-Arbutin showed no inhibitory effect on HMV-II cell growth at a concentration below 1.0 mM....

This study by scientists at Oxonica, Product Assessment & Regulatory Compliance, and SafePharm Laboratories Ltd. demonstrated that MatTek’s EpiDerm in vitro tissue model system can be used to determine the skin irritation potential of formulations containing nanoparticles. Nanotechnology is the... Read More
Dating back to work originally done by Rheinwald and Green, hydrocortisone (HC) is commonly used in culture media for epithelial cells, especially keratinocytes. In the culture of EpiDerm™, a highly differentiated, three-dimensional model of the human epidermis, this additive is... Read More
The need exists for a rapid, accurate in vitro screening protocol, predictive for human skin irritation in response to topically applied products. The EPI-100, EpiDerm™ Human Skin Model System produced by MatTek Corp. (Ashland, MA) is being investigated for this... Read More
