(A) TSC adhesion on various integrin ligands. Cell culture dishes were coated with increasing concentrations of EHS laminin-111 (EHS LM-111), recombinant laminin-111 (rLM-111), and recombinant laminin-111 EQ mutant (rLM-111 EQ). (B) TSC proliferation on non-coated, rLM-111–coated, and rLM-111 EQ–coated dishes. *P < 0.05, significant difference between non-coated and laminin-111–coated dishes by t test. (C) TSC proliferation on non-coated or rLM-111–coated dishes. 70CM+F4H was added (Non-coated +70CM+F4H) or depleted (Non-coated −70CM−F4H and rLM-111 −70CM−F4H). Data represent means ± SD (n = 3).
