Human Bone Marrow CD133+ Cells

Description

Human Bone Marrow CD133+ Cells represent a subset of hematopoietic stem and progenitor cells (HSPCs) in the bone marrow. Morphologically, these cells are usually round or oval, small in size, and have a high nuclear-to-cytoplasmic ratio. Functionally, CD133+ cells are involved in multiple physiological and pathological processes, including hematopoiesis, angiogenesis, and tissue regeneration. Studies have demonstrated their potential to differentiate into endothelial lineage cells, thereby contributing to neovascularization in ischemic tissues. Additionally, they may modulate the bone marrow microenvironment through paracrine signaling (e.g., cytokine secretion) or direct cell-cell interactions. These cells exhibit biological characteristics associated with the expansion of human bone marrow CD133+ cells and reflect the intrinsic regenerative potential of CD133+ cell populations at the molecular and phenotypic levels. The cells undergo rigorous screening and isolation procedures, and are rigorously tested to ensure they are free of contamination from HIV-1, HBV, HCV, Syphilis, Mycoplasma, Fungi, Yeast, and Bacteria.
