Contribution of Y chromosome BM SP cells to female recipient tracheas

Mouse Y Chromosome +ve Total DAPI nuclei % Y Chromosome +ve
SP1 23 1993 1.15
SP2 0 1281 0
SP3 9 1824 0.45

  • Cells were counted on the epithelial layer of the tracheas taken from the female CBA/Ca mice 3 months after tail vein injection of 1×104 male ROSA26 bone marrow SP cell and 7 days post intratracheal instillation of 2% polidocanol. From the mice injected with SP cells, 4/5 showed the presence of Y chromosome positive donor cells in their tracheas.
