| Research Abstract |
In a keloid lesion, T lymphocytes are found around activated and invasive keloid fibroblasts whose levels of type 1 collagen production, transforming growth factor-beta expression and α-SMA expression are very high. So we co-cultured keloid fibroblasts with T lymphocytes to establish the keloid in vitro model. But the levels of type 1 collagen and transforming growth factor-beta of the keloid fibroblasts co-cultured with T lymphocytes tended to rather decrease. Some subset of T lymphocytes might suppress keloid fibroblasts.
