A representative hematoxylin and eosin staining of UV-induced skin tumor or skin obtained from SKH-1 mice colonized by S. epidermidis 1457 or MO34, respectively, treated with UV-B for 12 weeks.

We update our services in dermocosmetology for Skin Pigmentation and Oxidative Stress

Summer is alway a good time to improve our services. Then we are very happy to introduce our updated Skin Pigmentation and Oxidative Stress services. Pigmentation is particularly regulated  at  the  cellular  level  by  melanocytes synthesizing  melanin  within  melanosomes,  which  can be  produced  in  varying  sizes,  numbers,  and  densities. In order to evaluate Read more…

Reticulated hyaluronan hydrogels: a model for examining cancer cell invasion in 3D

Abstract The extracellular polysaccharide hyaluronan (HA) controls cell migration, differentiation and proliferation, and contributes to the invasiveness of human cancers. The roles of HA cell surface receptors and hyaluronidases (HAses) in this process are still controversial. In order to investigate their involvement in cancer pathogenesis, we developed a reticulated HA Read more…

Hyaluronan hydrogel: An appropriate three-dimensional model for evaluation of anticancer drug sensitivity

Abstract The extracellular polysaccharide hyaluronan (HA) controls cell migration, differentiation and proliferation, and contributes to the invasiveness of human cancers. In order to investigate the sensitivity of cancer cells to antimitotic agents, we developed a cross-linked HA hydrogel, a three-dimensional matrix in which cells can invade and grow. We have Read more…

Drug discovery : Need of reliable IVIVE for pharmacodynamics and pharmacokinetics assessment

For ethical and cost-related reasons, use of animals for the assessment of mode of action, metabolism and/or toxicity of new drug candidates has been increasingly scrutinized in research and industrial applications. Physiologically based pharmacokinetic (PBPK2) modeling is the most potent in silico tool used for extrapolation of pharmacokinetic parameters to Read more…
