Abstract
Objectives: Hematopoietic stem cells (HSCs) are the cells that give rise to different types of blood cells during the hematopoiesis process. Mesenchymal stromal cells (MSCs) as key elements in the bone marrow (BM) niche interact with hematopoietic progenitor cells (HPCs) by secreting cytokines, which control HPCs maintenance and fate. Here we report that BM-MSCs are capable of inducing granulocytic differentiation of the C-Kit+ HSCs via activating JAK3/STAT3, ERK, and PI3K signaling pathways. Materials and Methods: HSCs with MSCs (experimental group). Afterward, the gene and protein expression were assessed by real-time PCR and western blotting, respectively. Results: HSCs. Conclusion: HSCs via increasing JAK3/STAT3, ERK, and PI3K signaling pathways.
