1. A stem cell isolation kit comprising:
- a) a first bag containing a plasma blood expander;
b) a second bag containing an anticoagulant and a growth medium, said second bag comprising an injection port for introduction of a biological sample comprising red blood cells and stem cells;
c) a third bag for collection of sedimented red blood cells from the second bag;
d) a fourth bag comprising an interior surface coated with a cell-adherent surface layer for collection and isolation of adherent stem cells;
e) a fifth bag containing a preservative for storage of adherent stem cells;
wherein said first and second bags are interconnected with each other through sterile tubing for transferring the contents of the first bag to the second bag;
the second and third bags are interconnected with each other through sterile tubing for sedimenting red blood cells from the second bag to the third bag;
the second and fourth bags are interconnected with each other through sterile tubing for transferring of stem cells from the second bag to the fourth bag; and
wherein the fourth and fifth bags are interconnected with each other through sterile tubing for the transfer of adherent stem cells from the fourth to the fifth bag.

Abstract
A method for isolating and processing bone marrow derived stem cells, including the steps of: (a) collecting a biological sample containing adherent bone marrow stem cells in a receptacle with interior walls coated with a cell-adherent substrate; (b) incubating the bone marrow cells on the adherent substrate so that a layer of adherent bone marrow stem cells adheres to the substrate; (c) washing any non-adherent cells from the substrate; and (d) collecting the bone marrow stem cell layer. Isolation kits and use of bone marrow cells harvested for cell therapies are also described.
