First Claim
Patent Images
1. A method of collecting autologous VSELs from a subject comprising the steps of:
- administering to the subject a stem cell potentiating agent;
collecting at least 1010 total nucleated cells from the peripheral blood of the subject;
enriching the total nucleated cells for CD34+/lin−
/CD45−
or Sca-1+/lin−
/CD45−
very small embryonic-like stem cells (VSELs);
preserving the collected cells to maintain the cellular integrity of the cells.
