OBJECTIVETo investigate the influence of the endothelial cells on the scar-derived fibroblasts in the hypertropic scar tissue.
METHODSThe endothelial cell from the human umbilical vein was cultured and its supernatant was then collected. Thereafter, it was mixed with the pre-cultured scar-derived fibroblasts from the hypertropic scar tissue. The fibroblasts were analyzed with a flow cytometer in a MTT-assay method to evaluate the cell proliferation and its division cycle.
RESULTSThe endothelial cells were significantly increasing the scar-derived fibroblast proliferation (P < 0.05), compared with the control. The proportion of the fibroblasts in the S-stage of cell cycle was also quite high.
CONCLUSIONThe endothelial cells may secrete some active products, which may enhance the proliferation of the scar-derived fibroblasts and stimulate the fibroblasts into the S-stage of cell generation cycle.

Objective·To establish a reliable alcoholic liver disease mouse model (ALDNM) that mimics the drinking pattern of alcoholic liver disease (ALD) patients.Methods·Using the self-designed feeding tubes and liquid diet,ALDNM model was developed through chronic feeding combined with acute gavage of ethanol based on Lieber-DeCarli model and Gao-Binge model.C57BL/6 mice were administered with control liquid diet for adaptation for first 5 d,and then divided into pair-fed group and ethanol-fed group (10 mice each group).Ethanol-fed mice were fed with the liquid diet in which ethanol accounts for 30% of total energy,while the pair-fed mice were fed with the control diet for 10 d.At the 16th day,ethanol-fed mice and pair-fed mice were respectively gavaged a single dose of 31.5% ethanol or isocaloric maltose dextrin,and euthanized 9 h later.Sera and livers were collected.The general physiological condition,hepatic tissue pathological changes and serum indexes between Lieber-DeCarli models and ALDNM models were compared.The liver lipids of ALDNM mice were determined by Oil red O (ORO) staining and hepatic triacylglyceride (TAG) test.Meanwhile,the mRNA levels of interleukin-6 (IL-6),tumor necrosis factor α (TNF-α),fatty acid synthase (Fas),long chain fatty acid elongase 6 (Elovl6) and stearyl-CoA desaturase (Scdl) were detected by real-time PCR in ALDNM models.Western blotting was used to detect the changes of phosphorylated signal transduction and transcriptional activator (p-STAT3) in the livers.Results·Lieber-DeCarli model mice were generally in poor condition,and there was no significant change in serum glutamic-pyruvic transaminase (GPT) and glutamic-oxaloacetic transaminase (GOT) compared to pair-fed group.However,in ALDNM models,H-E staining showed that the hepatocytes of ethanol-fed mice were extremely swollen with round volume,increased cytoplasm and filled with large amounts of fat vacuoles.ORO staining analyses showed obvious microsteatosis in the liver cells from all ethanol-fed mice.The hepatosomatic index,liver TAG content,serum GPT and GOT of ALDNM models were significantly higher than those in the pair-fed group,while the serum HDL significantly decreased compared to the pair-fed group.Moreover,the expression levels of both lipid synthesis pathways and inflammatory signaling pathways related genes in livers significantly increased in the ethanol-fed mice of ALDNM model.Conclusion·ALDNM model was successfully constructed.This model is cost-and time-efficient.Moreover,ALDNM model mimics the drinking pattern and pathogenesis of ALD patients with the advantages of stable food intake,good repeatability,and obvious liver damage.
