Human Stem Cells Promote Liver Regeneration After Partial Hepatectomy in BALB/C Nude Mice. J Surg Res 2019; 239:191-200. [PMID: 30844633 DOI: 10.1016/j.jss.2019.02.010] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Revised: 01/16/2019] [Accepted: 02/05/2019] [Indexed: 02/08/2023]
Abstract
BACKGROUND Mesenchymal stem cells (MSCs) have been suggested to augment liver regeneration after surgically and pharmacologically induced liver failure. To further investigate this we processed human bone marrow-derived MSC according to good manufacturing practice (GMP) and tested those cells for their modulatory capacities of metabolic alterations and liver regeneration after partial hepatectomy in BALB/c nude mice. METHODS Human MSCs were obtained by bone marrow aspiration of healthy donors as in a previously described GMP process. Transgenic GFP-MSCs were administered i.p. 24 h after 70% hepatectomy in BALB/c nude mice, whereas control mice received phosphate-buffered saline. Mice were sacrificed 2, 3, and 5 d after partial hepatectomy. Blood and organs were harvested and metabolic alterations as well as liver regeneration subsequently assessed by liver function tests, multianalyte profiling immunoassays, histology, and immunostaining. RESULTS Hepatocyte and sinusoidal endothelial cell proliferation were significantly increased after partial hepatectomy in mice receiving MSC compared to control mice (Hepatocyte postoperative day 3, P < 0.01; endothelial cell postoperative day 5, P < 0.05). Hepatocyte fat accumulation correlated inversely with hepatocyte proliferation (r2 = 0.4064, P < 0.01) 2 d after partial hepatectomy, with mice receiving MSC being protected from severe fat accumulation. No GFP-positive cells could be detected in the samples. Serum levels of IL-6, HGF, and IL-10 were significantly decreased at day 3 in mice receiving MSC when compared to control mice (P < 0.05). Relative body weight loss was significantly attenuated after partial hepatectomy in mice receiving MSC (2 d and 3 d, both P < 0.001) with a trend toward a faster relative restoration of liver weight, when compared to control mice. CONCLUSIONS Human bone marrow-derived MSC attenuate metabolic alterations and improve liver regeneration after partial hepatectomy in BALB/c nude mice. Obtained results using GMP-processed human MSC suggest functional links between fat accumulation and hepatocyte proliferation, without any evidence for cellular homing. This study using GMP-proceeded MSC has important regulatory implications for an urgently needed translation into a clinical trial.

Abstract
Gastrointestinal (GI) endoscopy is profoundly utilized for diagnostic and therapeutic purposes. The therapeutic potential of GI endoscopy has amplified many folds with the evolution of novel techniques as well as equipments. However, with the augmentation of therapeutic endoscopy, the extent, likelihood and severity of adverse events have increased as well. The attendant risks and adverse events with therapeutic endoscopy are many folds that of diagnostic endoscopy. Besides endoscopic resection, therapeutic endoscopy is widely utilized for hemostasis in GI bleeds, dilatation of stenosis, enteral stenting, foreign body removal, ablation of Barrett's esophagus etc. Major adverse events associated with interventional endoscopic procedures include bleeding and perforation. Adverse events of endoscopic interventions are diverse and related to the underlying disease, therapeutic modality used and operator's experience. Many of these adverse events can be prevented. Early recognition of an unavoidable adverse event is important to minimize the associated morbidity and mortality.

Abstract
We herein report the use of endoscopic n-butyl-2-cyanoacrylate injections to obliterate a gastric varix, which led to cyanoacrylate embolisation in the splenic and portal veins in a single patient. Cyanoacrylate embolisation is a known but uncommonly reported complication of endoscopic sclerotherapy. This case report illustrates the successful management of this complication (i.e. cyanoacrylate embolisation in the splenic and portal veins) with anticoagulation and analyses the presentation and management of other cases of cyanoacrylate embolisation reported in the literature.
