比较硬皮病患者真皮成纤维细胞系和正常对照真皮成纤维细胞系中转化生长因子β的产生和结合情况。硬皮病患者皮损皮肤成纤维细胞24小时分泌转化生长因子β的平均水平为30.8+/-5.5 pmoles/10(6)细胞,而正常人皮肤成纤维细胞分泌转化生长因子β的平均水平为29.7+/-5.8 pmoles/10(6)细胞。因此,我们发现成纤维细胞本身产生了转化生长因子β。来自硬皮病患者临床受累和非受累皮肤的成纤维细胞系产生的转化生长因子β是相同的。硬皮病成纤维细胞每个细胞的转化生长因子β受体的平均+/-扫描电子显微镜数目为9,736+/-1,375个,平均+/-扫描电子显微镜Kd值为25.2+/-3.9 PM。在对照组成纤维细胞中,这一值类似,每细胞12,431+/-2,425个转化生长因子β受体,平均+/-扫描电子显微镜Kd为27.1+/-5.2 PM
The production and binding of transforming growth factor beta (TGF beta) were compared in dermal fibroblast lines derived from scleroderma patients and normal control donors. The mean +/- SEM 24-hour level of secretion of TGF beta by fibroblast lines derived from the involved skin of scleroderma patients was 30.8 +/- 5.5 pmoles/10(6) cells, and it was 29.7 +/- 5.8 pmoles/10(6) cells for fibroblast lines derived from the normal skin of the healthy donors. Thus, we found that the fibroblasts themselves produced TGF beta. TGF beta production was equivalent in fibroblast lines derived from clinically involved and uninvolved skin of scleroderma patients. The mean +/- SEM number of TGF beta receptors per cell on scleroderma fibroblasts was 9,736 +/- 1,375, with a mean +/- SEM Kd of 25.2 +/- 3.9 pM. This value was similar in control fibroblasts, at 12,431 +/- 2,425 TGF beta receptors per cell, with a mean +/- SEM Kd of 27.1 +/- 5.2 pM.
