. The aim of this study was to analyse the expression of CO11A1, C011A2 and CO13A1 in 6 mm diameter punch biopsies obtained from human wounds. Total RNA was isolated from biopsies taken from Sacrococcygeal pilonidal sinus excision cavities at weekly intervals between surgery and clinical closure. cDNAs were generated from the RNA using reverse transcriptase and polymerase chain reaction (PCR) amplifications performed with oligonucleotide primer pairs specific for regions of the CO11A1, CO11A2 and C013A1 genes. The expression of these three genes was demonstrated throughout the course of healing on 36 biopsies taken from nine patients between surgery and clinical closure. Amplification bands demonstrated on cDNAs generated from 6 mm diameter biopsies were comparable in intensity and specificity with those generated from 50 mg excised scar tissue and cultured fibroblasts. The RT‐PCR technique described here allows the rapid ‘routine’ detection of specific gene expression in 6 mm biopsies obtained from healing wounds.
