2. Figure 1
Depiction of results evaluating quality of assay methods. (A–C) Comparison of the number of CD45hi/CD34+ cells from two sample tubes (Samples A and B) with the same specimen assayed simultaneously with the same procedure. (A) PBMCs. (B) Trochanteric bone marrow. (C) Femoral head bone marrow. The linear regression line is depicted visually, and the Spearman correlation (r) is noted. (D) Comparison of the results from GM-CFC assays of specimens from the same individual, but different locations—femoral versus trochanteric bone marrow. Numbers represent colonies formed per 1 × 105 mononuclear cells. For all figures, the linear regression line is visually depicted, and the Spearman correlation (r) noted.

3. Figure 2
Comparison of the proportion of CD45hi/CD34+ cells with the less differentiated CD45hi/CD133+ cells. Cells are represented as a percentage of peripheral blood mononuclear cells (A), trochanteric bone marrow mononuclear cells (B), or femoral bone marrow mononuclear cells (C). For all figures, the linear regression line is visually depicted and the Spearman correlation (r) noted.

4. Figure 3
The effect of age on hematopoietic stem cells in the various compartments. Numbers of CD45hi/CD34+ (A) and CD45hi/CD133+ (D) in the peripheral blood are depicted as percentage of peripheral blood mononuclear cells. HSCs in the bone marrow—trochanteric CD45hi/CD34+ (B) and CD45hi/CD133+ (E) and femoral CD45hi/CD34+ (C) and CD45hi/CD133+ (F)—are depicted as percentage of bone marrow mononuclear cells. The linear regression line is visually depictedm and the Spearman correlation (r) is noted.

5. Figure 4
Results represent GM-CFC colony number at day 14 per 1 × 105 bone marrow mononuclear cells plated—trochanter (A) and femur (B)—relative to age. To determine whether fat infiltration in the femur affected colony formation, (C) represents a comparison between GM-CFC and the amount of fat harvested from the femur (milligrams of fat per gram of bone marrow).
