Identification of a transcriptional signature for the wound healing continuum.

Peake MA, Caley M, Giles PJ, Wall I, Enoch S, Davies LC, Kipling D, Thomas DW, Stephens P - Wound Repair Regen (2014 May-Jun)

Bottom Line: Central to these outcomes is the role of the fibroblast.Genes whose expression increases following serum exposure in the order OMF < NF < CWF are candidates for a negative/impaired healing phenotype (the dysfunctional healing group), whereas genes with the converse pattern are potentially associated with a positive/preferential healing phenotype (the enhanced healing group).Sixty-six genes in the enhanced healing group and 38 genes in the dysfunctional healing group were identified.

The growth potential of fibroblasts isolated from adult oral mucosal, adult skin, and adult chronic venous leg ulcer tissues (n = 4 OMF; n = 7 NF1/NF2; n = 4 CWF). CWF, chronic wound fibroblast; NF, normal skin fibroblast; OMF, oral mucosal fibroblast; PDL, population doubling level.

fig03: The growth potential of fibroblasts isolated from adult oral mucosal, adult skin, and adult chronic venous leg ulcer tissues (n = 4 OMF; n = 7 NF1/NF2; n = 4 CWF). CWF, chronic wound fibroblast; NF, normal skin fibroblast; OMF, oral mucosal fibroblast; PDL, population doubling level.

Mentions: To illustrate the concept of a continuum of cellular responses between OMF, NF, and CWF, the growth kinetics of these cells were investigated through senescence. OMF had the greatest proliferative potential, proliferating for much longer in culture and senescing later than patient-matched NF1 (mean of 101.5 PD vs. 56.8 PD, respectively; p < 0.02; Figure 3). Conversely, CWF had the least proliferative potential, growing for a much shorter period of time in culture and senescing earlier than patient-matched NF2 (mean of 18.04 PD vs. 48.03 PD, respectively; p < 0.02). A comparison of NF1 (head/neck) with NF2 (thigh) showed a similar growth potential (p > 0.2). Therefore, for further analysis, three “sets” will be considered: OMF (four patient samples), NF (seven patient samples; 3× head/neck [one of the four samples failed quality control, see above] and 4× thigh), and CWF (four patient samples).
