Table 1 Frequency of LSK and long-term hematopoietic stem cells at different microenvironments and stages of development

From: Expression of migration-related genes is progressively upregulated in murine Lineage-Sca-1+c-Kit+ population from the fetal to adult stages of development

Tissue % LSK+ % LSK+CD150+CD48-CD41-
FL14.5 (n = 9) 0.45 ± 0.26 *† 0.004 ± 0.004 *
FL17.5 (n = 8) 0.78 ± 0.34 * 0.011 ± 0.006 *
FBM17.5 (n = 6) 1.19 ± 0.57 0.00 ± 0.00 *
Adult BM (n = 11) 2.94 ± 0.70 0.17 ± 0.08
  1. Data shown as mean frequency of live, Lin-/low gated events. The number of independent samples evaluated as n. An asterisk (*) indicates a significant difference (P < 0.05) of LSK or LT-HSCs percentage with adult bone marrow (BM) as reference sample (Tukey and Student's t-test analysis). A dagger (†) indicates a significant difference (P < 0.05) of LSK percentage with FBM17.5 as reference sample (Tukey and Student's t-test analysis). Adult BM, four-week old adult bone marrow; FBM17.5, fetal bone marrow at day 17.5 of gestation; LSK, Lineage- Sca-1+ c-Kit+; LT-HSC, Long Term-Hematopoietic Stem Cells.
