Recently, mesenchymal stromal cells (MSCs) and their derivative exosome have become a promising approach in the context of liver diseases therapy, in particular, acute liver failure (ALF). In addition to their differentiation into hepatocytes in vivo, which is partially involved in liver regeneration, MSCs support liver regeneration as a result of their appreciated competencies, such as antiapoptotic, immunomodulatory, antifibrotic, and also antioxidant attributes. Further, MSCs-secreted molecules inspire hepatocyte proliferation in vivo, facilitating damaged tissue recovery in ALF. Given these properties, various MSCs-based approaches have evolved and resulted in encouraging outcomes in ALF animal models and also displayed safety and also modest efficacy in human studies, providing a new avenue for ALF therapy. Irrespective of MSCs-derived exosome, MSCs-based strategies in ALF include administration of native MSCs, genetically modified MSCs, pretreated MSCs, MSCs delivery using biomaterials, and also MSCs in combination with and other therapeutic molecules or modalities. Herein, we will deliver an overview regarding the therapeutic effects of the MSCs and their exosomes in ALF. As well, we will discuss recent progress in preclinical and clinical studies and current challenges in MSCs-based therapies in ALF, with a special focus on in vivo reports.

Cancer is a group of diseases that include uncontrolled cell division and cell migration, as well as resistance to cell death

In this study we evaluated the influence of Alpinia officinarum rhizome extract (AO) on the alleviation of testicular damage induced by cisplatin in rats. The study groups included the control group, AO-administered group, cisplatin-administered group, and three groups administered with cisplatin and AO (different concentrations of 100, 200, and 400 mg/kg). On the 14^th day we removed the testes of the rats, and the testicular organ parameters were measured. Moreover, through the malondialdehyde concentration we assessed the oxidative stress and superoxide dismutase (SOD) activity of the testes and ran a histopathological analysis. The results demonstrated that cisplatin-induced oxidative stress and severe testicular damage on the AO-administered group showed no harm compared with the control group. AO- treatment in cisplatin-received rats led to the reduction of oxidative stress, enhancement of SOD activity, and prevention of testicular damage. The lowest testis damage was attributed to the group which received 400 mg/kg of AO compared to 100 and 200 mg/kg. Overall, the Cis+/AO+400 group had the best antioxidant effect. The findings could lead to changes in cancer care guidelines that incorporate phytochemicals, making cancer therapies safer.

This study aimed to evaluate the effect of Alpinia officinarum rhizome extract (AORE) on cisplatin (CP)-induced hepatotoxicity in rats. In this regard, 44 male rats were divided into six groups including the control group, AORE control group, CP control group, and three groups of CP (7 mg/kg dose, on the tenth day) with AORE (at concentrations of 100, 200 and 400 mg/kg, daily for 14 days). After 14 days, the rats' livers were removed and their liver function was assessed using biochemical marker enzymes. Oxidative stress was assessed by evaluating malondialdehyde concentration and hepatic superoxide dismutase activity and a histopathological test was also conducted. According to the results, the group treated with CP had severe liver damage and the group treated with AORE had no harm compared with the control group. Among the groups receiving CP and AORE (at different concentrations), the group with 200 mg/kg AORE showed the lowest liver damage compared to the other two groups.
