LAMC2 and idiopathic pulmonary fibrosis: Expression of mRNAs for proteins involved in anchoring (LAMA3, LAMB3, and LAMC2) and hemidesmosomal complexes (ITGA6, ITGB4, PLEC, CD151, DST, and COL17) was up-regulated in the basal cell populations from IPF compared with that in controls (Supplemental Figure S6).
