Fig. 1. Absence of {alpha}3ß1 from keratinocytes leads to increased apoptosis upon serum deprivation. Wild-type MK+/+ cells (A,B), {alpha}3-null MK-/- cells (C,D), or {alpha}3-transfected MK-/- cells (E,F) were cultured on LN-5 ECM in serum-free medium for two days. Apoptotic cells were identified by TUNEL staining (A,C,E); corresponding phase images are shown (B,D,F, respectively). Examples of apoptotic cells are indicated with arrows in C and D. (G) Flow cytometry was performed and the percent of TUNEL-positive cells was determined for MK-/- cells (MK-/-), or {alpha}3-transfected MK-/- cells (MK{alpha}3) grown in the presence (white bars) or absence (black bars) of serum.
