Fig. 2From: Intra-discal injection of autologous, hypoxic cultured bone marrow-derived mesenchymal stem cells in five patients with chronic lower back pain: a long-term safety and feasibility studyTotal number of cells injected versus the overall improvement. Scatter plot displaying the overall improvement reported by patients under the quality of life questionnaires (values from Table 3) against the total number of cells injected into these patients (values from Table 1). The trend line shows positive correlation between the overall improvement and the total number of hypoxic cultured MSCs injectedBack to article page
