The authors have adopted a new nomenclature for the laminins. They are numbered with
arabic numerals in the order discovered. The previous A, B1 and B2 chains, and their
isoforms, are alpha, beta and gamma, respectively, followed by an arabic numeral to
identify the isoform. For example, the first laminin identified from the Engelbreth-Holm-Swarm
tumor is laminin-1 with the chain composition alpha 1 beta 1 gamma 1. The genes for
these chains are LAMA1, LAMB1 and LAMC1, respectively.
