BACKGROUND/AIMS: Liver is considered as the vital organ in the body as it performs various essential functions. Following an injury to the liver, the repair process even though initially beneficial becomes pathogenic when it is not controlled appropriately. Extensive accumulation of extracellular matrix (ECM) components can ultimately lead to cirrhosis and liver failure. Thus, the ideal strategy to treat a liver injury is to generate new hepatocytes replacing damaged cells without causing excessive ECM deposition. The objective of this study was to evaluate the potential of mesenchymal stem cells, conditioned media and murine epidermal growth factor (m-EGF) in liver regeneration following partial hepatectomy in a rat model. METHODS: The animals were anaesthetized and a midline laparotomy was done. The liver was exposed and the left lateral and median lobes were ligated and resected out (about 65-70% of total liver mass). The muscles and skin were sutured in routine fashion and thus the rat model of partial hepatectomy was prepared. The animal models were equally distributed into 4 different groups namely A, B, C and D and treated with PBS, conditioned media, mesenchymal stem cells and epidermal growth factor respectively. The liver regeneration was assessed based on clinical, haemato-biochemical, colour imaging, histopathological and immune-histochemical parameters. RESULTS: Partial hepatectomy model with surgical removal of 65-70% liver lobe was standardized and successfully used in this study. Alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), bilirubin, transaminases were significantly higher (P<0.05) in group A indicating that the liver damage was not restored properly. Colour digital imaging, histopathological and immune-histochemistry observations revealed that a better liver regeneration was observed in groups C and D, followed by groups B and A. Regeneration coefficient calculated based on liver weight was higher in groups C and D as compared to group A. CONCLUSION: Rat bone marrow-derived mesenchymal stem cells were found to induce hepatocytes proliferation; whereas EGF induced more angiogenesis. Conditioned media was not as effective as stem cells and EGF in liver tissue repair.

ABSTRACT The role of epidermal growth factor (EGF) in liver regeneration was studied in mice after partial hepatectomy. Two weeks before partial hepatectomy, mice were sham-operated (control) or sialoadenectomized (removal of submandibular glands) to reduce plasma EGF levels. Sialoadenectomized mice showed low plasma EGF levels (29·7 ±6·6 pmol/l; mean ± s.e.m.) compared with controls (66·0±8·3 pmol/l). After partial hepatectomy, sialoadenectomized mice were treated with or without a daily s.c. injection of 5 μg EGF and the rate of DNA synthesis in the regenerating liver was monitored by [125I]iododeoxyuridine uptake. Control mice showed a sharp peak of DNA synthesis at 48 h after partial hepatectomy while sialoadenectomized mice showed a delayed and broad peak at 84 h. Treatment of sialoadenectomized mice with EGF (5 μg/mouse per day) completely restored the pattern of DNA synthesis so that a sharp peak appeared at 48 h. The total liver DNA content of the control mice (79·1±2·5% of the preoperative level; mean ± s.e.m.) was significantly (P < 0·01) higher than that of the sialoadenectomized mice (65·2±3·0%) 3 days after partial hepatectomy, but this difference disappeared on day 7 when liver regeneration was almost completed in both groups. Treatment of sialoadenectomized mice with EGF increased total liver DNA content (78·2±2·9%) to that of control mice on day 3 after partial hepatectomy. In addition, normal mice showed a rapid increase in plasma EGF levels at 1–8 h after partial hepatectomy, whereas sialoadenectomized mice showed low plasma EGF levels throughout the course of the experiment. These results suggest that EGF derived from the submandibular glands plays a role in promoting the early stage of liver regeneration. Journal of Endocrinology (1991) 128, 425–431

BACKGROUND: Research on human bone marrow mesenchymal stem cells (hBM-MSCs) for burns healing has been known to increase the percentage of integrin expression of α2β1, type I collagen, transforming growth factor-β, and matrix metalloproteinases-9, but research on giving hBM-MSCs to growth factor expression in the process of re-epithelialization of burn healing has not been done. AIM: This study aims to the effect of hBM-MSCs given on the expression of epidermal growth factor (EGF) and EGF receptor (EGFR) in the process re-epithelialization in the healing of burn experimental rat. MATERIALS AND METHODS: This research is experimental with the post-test only control design, using 30 Wistar rats. Rats were divided into two groups, namely, control (phosphate-buffered saline), and the treatment was given hBM-MSCs, and stem cells were given subcutaneous doses of 2 × 106 cells/ml. Before being treated rats were anesthetized using xylazine and ketamine then the rats were burned in the dorsal (spine) with full-thickness. On the 3, 7, and 14 days, skin tissue was taken to see the expression of EGF and EGFR by immunohistochemical methods. This study was approved by the Ethics Commission of the Faculty of Medicine, Andalas University, Padang. The results of the study were analyzed by the t-test. RESULTS: Immunohistochemical examination of EGF and EGFR expressions after hBM-MSCs administration has significantly increased epithelialization compared with controls. Increased EGF expression was found on days 3 and 7 with moderate positive internal revenue service (IRS) assessment and on day 14 strong positive EGF expression, as well as EGFR expression on days 3 and 7 with moderate positive IRS assessment and on day 14 robust positive EGFR expression. CONCLUSION: This study concluded that giving of hBM-MSCs can increase the expression of EGF and EGFR which enhances the process of re-epithelialization thereby accelerating the healing of burns of experimental rats.
