(a): Mesenchymal stem cells in culture (Passage 3) under the inverted microscope (40×).

(b-d): Olympus cell counter- printed reports: one out of the 20 umbilical cord samples were cultured and passaged successfully until passage 7. (b): cell count report of harvested cells from one culture flask between passage 3 and passage 4, showing viable cell count of 893,000 cells/ml. (c): cell count report of harvested cells from one culture flask between passage 5 and passage 6, showing viable cell count of 4.55 million cells/ml. (d): cell count report of harvested cells from one culture flask between passage 6 and passage 7, showing viable cell count of 3.17 million cells/ml.
