Incidence of human ductal growth in recombinants with representative number of sorted cells.

*Grafts not analyzed due to host animal death. ND: Not Determined because the recombinant did not demonstrate visible ductual growth upon micro-dissection.
**There was a 33-fold ratio between non-side and side population cells isolated, however due to the number of cells isolated only a 25-fold ratio was possible for the recombinants from this specimen.
