Dependence of the number of eGFP⁺ cells in organs of blood system (BM, spleen, thymus, and blood) of the recipient mice on time after BM transplantation. (a) eGFP C57Bl/6 strain (syngeneic transplantation); (b) BALB strain (allogeneic transplantation) (green: BM, blue: spleen, yellow: thymus, and orange: blood). The abscissa axis indicates time after transplantation in days; the ordinate axis indicates number of eGFP⁺ cells (: arbitrary units). Solid lines represent a cubic polynomial approximation. (Error: mean ± SD, the mean of values of 2–6 experiments per point).
