LAMB2 and neoplasm: HASM cells were thus re-plated from serum-fed confluent cultures on dishes pre-coated with different laminin preparations, including (1) laminin from EHS tumours that contains laminin type 1 (laminin 111) isoform, (2) affinity purified β1 chain-containing laminin from human placenta that includes laminin-1 (laminin 111), 2 (laminin 211), 6 (laminin 311), 8 (laminin 411), 10 (laminin 511) isoforms, and (3) affinity purified α2 chain-containing laminin from human placenta that consists of laminin-2 (laminin 211) and 4 (laminin 221).
