Wound healing is a complex process in which a tissue's individual cells have to be orchestrated in an efficient and robust way. We integrated multiplex protein analysis, immunohistochemical analysis, and whole-slide imaging into a novel medium-throughput platform for quantitatively capturing proliferation, differentiation, and migration in large numbers of(More)
BACKGROUND Determining the correct number of positive immune cells in immunohistological sections of colorectal cancer and other tumor entities is emerging as an important clinical predictor and therapy selector for an individual patient. This task is usually obstructed by cell conglomerates of various sizes. We here show that at least in colorectal cancer(More)
BACKGROUND A role for cutaneous human beta-papillomavirus (HPV) types as co-factors in the development of non-melanoma skin cancer has been postulated. Here we have investigated the effects of E7 expression on keratinocyte differentiation, proliferation and cell-cycle proteins in organotypic skin cultures. METHODS Recombinant retroviruses containing the(More)
Cutaneous regeneration utilizes paracrine feedback mechanisms to fine-tune the regulation of epidermal keratinocyte proliferation and migration. However, it is unknown how fibroblast-derived hepatocyte growth factor (HGF) affects these mutually exclusive processes in distinct cell populations. We here show that HGF stimulates the expression and(More)
MOTIVATION For a mechanistic understanding of skin and its response to an induced perturbation, systems biology is gaining increasing attention. Unfortunately, quantitative and spatial expression data for skin, like for most other tissues, are almost not available. RESULTS Integrating organotypic skin cultures, whole-slide scanning and subsequent image(More)
We developed a method for the quantification of skin irritation based on the treatment of skin cultures and the subsequent automatic image analysis of fluorescently stained tissue sections being scanned with a fullslide scanner. In this method, the irritative effect is reflected in a shift of the expression pattern of selected biomarkers inside the(More)
