  1. Regenerated tails from proximal and distal blastemas were collected on day 10 post-amputation, fixed, cryosectioned and total mesenchymal cell numbers counted (see Methods). The table compares the total cell counts, the calculated number of progenitor cells required to give rise to the total cell number within 10 days (accounting for all proliferation parameters, see Methods), the counted cell numbers within the amputation plane and the calculated spatial extent of the progenitor pools for both amputation levels. Despite several individual parameters differing between amputation levels, the distances the progenitor pools extend proximal to the amputation plane are similar within the confidence intervals
