Figure 2

Growth and colony‐formation is induced in secretory leukocyte protease inhibitor (SLPI) transfectants independently of protease inhibitor (PI) activity. (A, B) No difference in relative proliferation rates (A) or soft agar colonization (B) of stable transfectants between wild type (WT)/SLPI and the protease‐inhibitor null (PI‐) mutants (n = 5). (C, D) Similar growth advantage in soft agar was observed for WT/SLPI and PI‐ mutants. Number of colonies (C) and colony size (D) were quantitated using digital pictures taken at a 9.5 × magnification. Representative data of three experiments are shown. All P‐values are compared to the mock transfection control. F‐SLPI, PI‐/SLPI mutant Leu72Phe; R‐SLPI, PI‐/SLPI mutant Leu72Arg.
