The authors have adopted a new nomenclature for the laminins. They are
numbered with arabic numeral in the order discovered. The previous A,
B1 and B2 chains, and their isoforms, are alpha, beta and gamma and r
espectively, followed by an arabic numeral to identify the isoform. Fo
r 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.
