Donor Age and Gender Are the Strongest Predictors of Marrow Recovery From Cadaveric Vertebral Bodies
Abstract:The purpose of this retrospective analysis was to determine whether there were donor factors that were useful for predicting the yield of nucleated cells from marrow derived from cadaveric vertebral bodies. An analysis of 132 donors over a 6-year period was performed. The average number of vertebral bodies procured from each donor was 10.2 ± 1.6 (range 5–14). The total number of nucleated cells recovered per donor ranged from 24 × 109 to 160 × 109 with an average recovery of 69 ± 28 × 109 cells. The cell viability of the recovered cells was >95%. The average age of the donors was 33 ± 14 years (mean ± SD; range 12–65) with an average weight of 169 ± 41 lb (range 82–308 lb). Males comprised 68% of the donor population. The average number of days from admission to death was 1.9 ± 1.7 with a range of 1–11.4 days and the interval between asystole and procurement averaged 3.1 ± 2.3 h (range (0.1–14.7 h). The majority of donors died from head trauma due to an intracranial bleed, gunshot wound, or closed head injury. Regression analysis of the data indicated that the total nucleated cell yield tended to decrease with increasing time between hospital admission and death. The data also indicated that in general female donors yielded lower cell numbers independent of age and male donors under 30 years of age yielded the highest number of cells.

More about this publication?
- Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
