Abstract
The present invention provides a cell culture for obtaining an epithelial organoid, the cell culture comprising i) epithelial stem cells, or tissue fragments comprising said epithelial stem cells, ii) a basal medium for animal or human cells, iii) a Bone Morphogenetic Protein (BMP) inhibitor, iv) a mitogenic growth factor selected from the group consisting of epidermal growth factor (EGF), transforming growth factor-alpha (TGF-alpha), basic fibroblast growth factor (bFGF), brain-derived neurotrophic factor (BDNF) and keratinocyte growth factor (KGF), v) at least one soluble culture enhancer, wherein said at least one culture enhancer induces correct polarization of the cells in said cell culture within the developing organoid such as a laminin/entactin complex or entactin, and vi) a Wnt agonist if said epithelial stem cells, or tissue fragments comprising said epithelial stem cells are healthy cells, wherein said at least one soluble culture enhancer in said cell culture is a laminin/entactin complex in a concentration between 0.2 mg/ml and 3.4 mg/ml. A cell culture medium, an in-vitro method for obtaining an epithelial organoid, and an epithelial organoid obtained by said method are also disclosed.
