The α(7)β(1)-integrin is an adhesion molecule highly expressed in skeletal muscle that can enhance regeneration in response to eccentric exercise. We have demonstrated that mesenchymal stem cells (MSCs), predominantly pericytes, accumulate in muscle (mMSCs) overexpressing the α(7B)-integrin (MCK:α(7B); α(7)Tg) and contribute to new fiber formation following exercise. Since vascularization is ...

The stratum corneum (SC) serves a primary function of skin barrier and understanding the kinetics of SC formation may provide great insight for skin diagnosis and evaluation of therapies. Besides trans-epidermal water loss (TEWL), few methods have been characterized to assess skin barrier non-invasively in vivo, particularly for dynamic measurements ...

Cell surface receptors bearing immunotyrosine-based inhibitory motifs (ITIMs) maintain natural killer (NK) cell tolerance to normal host tissues. These receptors are difficult to analyze mechanistically because they block activating responses in a rapid and comprehensive manner. The advent of high-resolution single cell imaging techniques has enabled investigators to explore the ...
