摘要: Content and aims: Ginsenoside RG1 (RG1) is thought to enhance proliferation differentiation of stem cell, however, its role on paracrine efficacy cell remains unclear. Here we examined if how enhances the effects bone marrow-derived mesenchymal cells (BM-MSCs) radiation induced intestinal injury (RIII). Method Irradiated rats randomly received intraperitoneal injection conditioned medium (CM) derived from non-activated BM-MSCs (MSC-CM) or pre-activated by RG-1 (RG1-MSC-CM). Intestinal samples were collected, followed evaluation histological functional change, apoptosis, proliferation, inflammation, angiogenesis regeneration. The heme oxygenase-1 (HO-1) investigated using HO-1 inhibitor siRNA. Result enhanced partially through upregulation HO-1. RG1-MSC-CM rather than MSC-CM significantly improved survival damage irradiated via improvement proliferation/apoptosis, regeneration in a dependent mechanism. mechanism for superior related higher release two pivotal cytokines VEGF IL-6. Conclusion Our study revealed that RIII, providing novel method maximizing potential MSCs.
