The concentration of CD45^dim/CD34⁺ (HSC) (a), CD45⁻/CD271⁺ (MSC) cells (b), CFU-F (c), and CD45⁻/CD73⁺⁻/CD90⁺⁻/CD105⁺ (MSC) (d) in bone marrow samples correlated to the patient’s age. Empty circles present 1 × 30 mL aspiration, solid filled circles present 3 × 10 mL aspiration of bone marrow. The R² values were obtained by exponential curve fitting for each aspiration technique separately (n = 21)
