Clonogenic growth of porcine mesenchymal stromal cells isolated from the mandible after fractionated irradiation with 2 χ 9 Gy. (A) Colony formation of primary cultivated cells isolated 4–6 weeks post-irradiation and (B) integration of data accounted from all primary cultures isolated at the latter time points. (C) Integration of data accounted from all assessments of osteogenic differentiation with MSC isolated at time points indicated in (A). Specification of arbitrary units, see Materials and methods. Experimental results in bar graphs are shown as mean ± standard deviation.
