Mouse colon colony assay. Titration of 2 batches of LIM1863 conditioned medium using a single-cell suspension isolated from murine colonic crypts. Both colonies (>40 cells) and clusters (15-40 cells) were counted after 23 days. Each assay was performed in triplicate.

(A) Electron micrograph of a section through 4 cells of a colony of mouse colonic cells picked from agar after 28 days in culture. The viability of the cells is confirmed by the intact nuclei and cytoplasmic organelles. Lipid droplets can be seen in the cytoplasm of some cells. Tight junctions are present at the apical junctions between cells (arrows). No microvilli or mucin inclusions were found (original magnification 3600×). (B) Apical junctional complex (arrow) between 2 adjacent cells in a colony derived from mouse colonic epithelial cells. Each cell was joined to neighboring cells by a similar junction in the apical region (original magnification 12,600×).
