NCM460 Cells

The NCM460 cell line is derived from normal human colon mucosal epithelial cells, providing a critical in vitro model for studying human intestinal physiology and pathology. This cell line was established from histologically normal tissue isolated during surgery from a gastric cancer patient, specifically from the transverse colon margin considered free of malignant changes. NCM460 cells exhibit characteristics typical of gastrointestinal epithelial cells, including the expression of markers such as villin and human secretory component, confirming their epithelial origin. Importantly, these cells maintain a non-tumorigenic phenotype, as demonstrated by their inability to grow in soft agar and lack of tumor formation in nude mice.

The culture of NCM460 cells requires specialized conditions to support their growth as a mixed suspension-monolayer system, reflecting varying stages of epithelial differentiation. The presence of mucin-positive cells and neuroendocrine marker expression in some subpopulations suggests a retained multilineage capability, indicative of a stem-like component within the cell population. This property makes NCM460 particularly useful for studies on cell differentiation, drug transport, and epithelial barrier functions.

NCM460 has been widely applied in research focusing on colon cancer progression, allowing comparisons between normal and diseased epithelial cells. It also serves as a platform for investigating the effects of dietary components, pharmaceuticals, and other external factors on colon epithelial health and disease. This cell line offers a robust tool for advancing our understanding of gastrointestinal biology at the cellular and molecular levels.
