| pubmed-article:3768938 | pubmed:abstractText | Non-cycling pluripotent bone marrow stem cells (CFU-S), taken 3 hrs after injection of 20 mg of Ara-C, have been shown to enter DNA synthesis at 1 to 3 hr after being cultured in alpha-medium. This phenomenon was observed when bone marrow was incubated as a plug, but not when incubated as a cell suspension in the present experimental conditions. These results suggest that a medullary structure is necessary in order to observe this effect and/or that accessory cells are destroyed during the process of single cell preparation. | lld:pubmed |
