Lining Xie, Yoichi Moroi, Gaku Tsuji, Min Liu, Sayaka Hayashida, Masakazu Takahara, Shuji Fukagawa, Satoshi Takeuchi, Baoen Shan, Takeshi Nakahara, Hiroshi Uchi, Takehiko Yokomizo and Masutaka Furue. CD10-bearing fibroblast inhibits matrigel invasive potency of interleukin-1α-producing squamous cell carcinoma by diminishing substance P levels in the tumor microenvironment. Cancer Science 2010; 101: 2570–578.

On page 2572, the paragraph on ‘Plasmid construction’ should have read:

The ORF of hCD10 was amplified from commercially available cDNA clones (DNAFORM, Yokohama, Japan) by PCR using a sense primer (5′-CTAGCTAGCATGGGCAAGTCAGAAAGTCAGATGG-3′) covering a NheI site and an antisense primer (5′-CGGGGTACCTCACCAAACCCGGCACTTCTTTTCT-3′) at the stop codon covering a KpnI site. The PCR product was subcloned into the NheI/KpnI site of pCXN2.1(+) and designated pCXN2.1(+)-hCD10. Accurate amplification of the insert was verified by DNA sequencing.

The authors apologize for this error and any confusion it may have caused.
