Abstract:
Objective Vimentin is one of the proteins of cytoskele to n and cell movement. To investigate the effect of gene expression of fibroblast vimentin on the formation and contraction of hypertrophic scar in this report. Methods According to the results of differently expressed genes in hypertrophic scar by gene microarray, Vimentin, one of the most important g enes , was selected and made into oligonucleotide probe. 24 cases of hypertrophi c scar and 24 non-hypertrophic scar and 12 normal skin were used and these scar were taken on 3, 6, 9 and 12 months after burned. Frozen section and cultured f ibroblasts were made to detect the expression of the gene by in situ hybridizati on. Results Expression of vimentin was defected in scar tissue, but those in the hypertrophic scar on 3 and 6 months after burn were significan tly stronger than those in the hypertrophic scar on 9 and 12 months after burn a nd non-hypertrophic scar. Conclusions Over-expression of cyto skeletal relative genes causes the contraction of scar and vimentin acts leading and key functions.
