Figure 4From: Transdifferentiation of pancreatic cells by loss of contact-mediated signalingCell density affects conversion efficiency. (A) The fraction of acinar cells that convert to islet cells increases with decreasing cell density, as shown for three values of lateral stabilization strength, b=1 (dotted), b=0.1 (solid), b=0.01 (dashed). (B) Examples of the steady-state situation (acinar cells in red and islet cells in blue) for three different cell densities as indicated on the dashed curve (b=0.01, densities 0.25, 0.50 and 0.75). Note the presence of compact clusters of stable acinar cells in the middle panel. (C) Shape of cellular aggregates determines the efficiency of conversion. A decrease in compactness, measured as average neighbors per cell, increases the islet cell yield. Parameters as in Table 1, b as indicated.Back to article page
