Abstract: Methods and systems for detection of precancerous colorectal cancerous lesions and early stage colorectal cancer are described. The methods and systems include examination of a rectal cell sample for the presence of mast cells in a field effect detection regime. The methods can incorporate swab-based cell collection, optionally storage and transportation of a cell sample, and/or computer-aided diagnosis.

Abstract: Embodiments of the invention include systems and media for mammalian cell culture that enhance cell viability which enables biological assays and quantitative studies in tissues such as skin explants. Certain embodiments may be used in coordination with each other or may be practiced separately. An exemplary embodiment of the invention is a culture medium that includes Dulbecco's Modified Eagle's Medium, X-VIVO medium, and subcutaneous adipocyte medium. In one embodiment the culture medium includes approximately 30-60% Dulbecco's Modified Eagle's Medium by volume, approximately 30-60% X-VIVO medium by volume, and approximately 2.5-15% subcutaneous adipocyte medium by volume. Certain embodiments of the culture medium can also include recombinant human stem cell factor. Embodiments of the invention disclosed here are not limited to the brands described and encompass equivalents, as well as combinations, of the individual chemical components that make up the media described herein.
