In the present experiment, we noticed that 7 days after the intraperitoneal injection of different doses of RRPs, the protein expressions of Fas and FasL were decreased in BMCs, indicating that under the present modelling conditions, RRPs could inhibit BMC apoptosis by influencing the Fas/FasL apoptotic pathway and thereby promote the restoration of haematogenesis in mice with aplastic anaemia. Here, FAS is linked to aplastic anemia.
