Abstract
- Context The effects of Rhodiola rosea L. (Crassulaceae) polysaccharides (RRPs) on haematopoiesis are poorly understood.Objective To determine the effects of RRPs on haematopoiesis in mice with aplastic anaemia.Materials and methods Aplastic anaemia was induced in Kunming mice by 60Coγ (2.0 Gy) irradiation and cyclophosphamide administration (50 mg/kg/day for 3 consecutive days; intraperitoneal injection). The in vivo effects of RRPs (10, 20, and 40 mg/kg; intraperitoneal injection) on haematopoiesis were analyzed using peripheral blood tests, histopathological examination of haematopoietic tissues, culture of haematopoietic progenitors and bone marrow stromal cells (BMSCs), and Western blotting of Fas and Fas ligand (FasL). The in vitro effects of RRPs on bone-marrow haematopoietic progenitors and BMSCs were also evaluated.Results Compared to anaemic controls, high-dose RRPs (40 mg/kg) significantly increased red blood cells (8.21 ± 0.57835 versus 6.13 ± 1.34623 × 1012/L), white blood cells (5.11 ± 1.6141 versus l.54 ± 1.1539 × 109/L), and BMSCs (10.33 ± 1.5542 versus 5.87 ± 3.1567 × 1012/L) in mice with aplastic anaemia (all p
