  • USE OF COMPOUND FOR IMPROVING TRANSPLANTATION EFFICIENCY OF HUMAN HEMATOPOIETIC STEM CELLS
    Publication number: 20240026295
    Abstract: Provided is the use of a compound for improving the transplantation efficiency of human hematopoietic stem cells, wherein the compound is selected from one of or two or more of a tubulin polymerization inhibitor, LND-212854, AZD0364, SCH772984, Pimasertib, Trametinib, IWR-1-endo, TTNPB, JNK-inhibitor IX and CHIR99021. The compound provided can improve the expression of the hematopoietic stem cell surface protein CD184 by means of in vitro short-time treatment, without affecting the phenotype, survival rate and various characteristics of the cell. By means of the binding of the chemokine receptor CD184 expressed by HSC to the chemokine ligand SDF1 in the bone marrow microenvironment, the migration ability of the HSC and the homing ability thereof in the bone marrow are improved, and the transplantation efficiency and the therapeutic effect of the HSC are enhanced.

  • CELL PREPARATION, USE OF PROTEIN IN CHARACTERIZING HEMATOPOIETIC STEM CELLS, AND METHOD FOR DETERMINING HEMATOPOIETIC STEM CELLS
    Publication number: 20240011988
    Abstract: Provided are a cell preparation, a use of a protein in characterizing hematopoietic stem cells, and a method for determining hematopoietic stem cells. The cell preparation is CD34+, CD90+, CD45RA? sorted and obtained from among cells to be sorted, and hematopoietic stem cells that are positive for the following proteins, the protein being selected from one or more among CD48, CD66a, CD66c, CD66d, CD66e, and CD200. By using the foregoing protein(s) to characterize hematopoietic stem cells, not only can target cells be more accurately calibrated and evaluated in vitro, but the ability of a patient to maintain long-term reconstruction of the hematopoietic system after receiving a hematopoietic stem cell transplant can also be improved, achieving a better treatment effect.
