Quantitative of hematopoietic progenitors is commonly done with the use of colony assays. Purpose: Assessment of number and types of cell colonies were formed from bone marrow, cord blood and peripheral blood stem cell samples. Materials and Method: 49 samples were placed in methylcellulose-based colony assay media. Results: Bone marrow samples were formed 322 + or - 25 colonies/10 exponent 5 nucleated cells, include CFU-GEMM (23.4 percent) and CFU-GM (21.6 percent). CFU-G colonies were highest counted form PBSC samples (33.6 percent) and cord blood were highest archived of BFU-E (43.8 percent). Conclusions: Number of cell colonies and its types were different from sources of cell cultured. There results would be useful for choice of cell sources for transplantion.
