Fig 1. The proliferation and attachment of oral mucosal epithelial cells in the presence of calpain inhibitors.

Fig 1

(A) Phase contrast microscopic images of cultured rat oral mucosal epithelial cells. The bars indicate 200 μm. (B) The cells were collected and counted at 8–11 days after seeding (calpeptin, n = 4; calpain inhibitor III, n = 3; calpastatin, n = 3; B27-WT, n = 3; and cystatin C, n = 2). White blocks, controls; blue blocks, inhibitors. * P < 0.05 using Student's t-test. (C) The number of initially attached epithelial cells was determined 48 h after seeding (n = 4). The error bars indicate the SD. * P < 0.05 using Student's t-test.
