Figure 5. Differential partition of ICK/MAK/MOK proteins between intestinal epithelial and mesenchymal cells.

Intestinal epithelial cells and mesenchymal cells were isolated and enriched from small intestine (A) and colon (B) tissues of young adult C57BL/6J mice. ICK/MAK/MOK protein signals in these two distinct cell populations were analyzed on Western blot. The E-Cadherin signal was used as a marker for epithelial cells and the VIM (Vimentin) and α-SMA (α-Smooth Muscle Actin) signals were used as markers for mesenchymal cells. The ERK1/2 signals were shown to indicate an equal distribution pattern between the epithelial and mesenchymal cell populations.
