In addition we report pockets of CXCR4 expression that lack co-localization with CXCL14 in IPF lungs (Fig. 6H) which confirms a widely observed trait in normal tissue sections (Fig. 6P,L,N), specfically this phenomon is most distinct in the airways of both normal (Fig. 6N) and IPF (Fig. 6H) sections. Here, CXCL14 is linked to idiopathic pulmonary fibrosis.
