Radiosensitivity of hematopoietic myeloid progenitor cells.

<p>Values are the mean±SE. of 6–8 separate experiments. <i>P</i> values were calculated using two-factor factorial ANOVA and Tukey–Kramer test. A significant difference was observed between <i>D₀</i> and <i>n</i> for radiation types (<i>D₀</i>: <i>P</i> = 1.40×10⁻⁹, <i>n</i>: <i>P</i> = 1.16×10⁻⁷) and for each progenitor (<i>D₀</i>: <i>P</i> = 1.75×10⁻³, <i>n</i>: <i>P</i> = 4.53×10⁻⁸). <i>^aP</i> = 4.97×10⁻² vs. BFU-E, <i>^bP</i> = 1.33×10⁻⁴ vs. CFU-Mix, <i>^cP</i> = 6.55×10⁻³ vs. CFU-Mix, <i>^dP</i> = 9.49×10⁻⁴ vs. CFC, <i>^eP</i> = 2.87×10⁻³ vs. CFU-GM, <i>^fP</i> = 4.01×10⁻² vs. CFU-Mix, <i>^gP</i> = 4.64×10⁻³ vs. CFC in X-rays. <i>^hP</i> = 3.79×10⁻⁶, <i>ⁱP</i> = 0.00196, <i>^jP</i> = 6.51×10⁻⁵, <i>^kP</i> = 2.34×10⁻³, <i>^lP</i> = 2.50×10⁻² compared with X-rays.
