MEIS1 is a transcription factor expressed in hematopoietic stem and progenitor cells and in mature megakaryocytes. This biphasic expression of MEIS1 suggests that the function of MEIS1 in stem cells is distinct from its function in lineage committed cells. Mouse models show that Meis1 is required for renewal of stem cells, but the function of MEIS1 in human hematopoietic progenitor cells has no...

Acute myeloid leukemia (AML) is a disease characterized by neoplastic transformation and abnormality of progenitor cells differentiation from cells. In AML there heterogeneous in hematopoietic cells, this has been identified affects the balance between proliferation, survival body Mutation FMS-like tyrosin kinase 3 (FLT3) gene causes overexpression which one most often found mechanism that coul...

The hematopoietic cells are multipotent primitive cells, which differentiate into either common myeloid and lymphoid progenitor. However, if there an abnormality in this process of differentiation, condition leukemia arises, is the 11th leading cause cancer-related mortality worldwide year 2018. These abnormalities brought about by array mutations occurring at cellular level. According to two-h...

stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. they are found in multicellular organisms. in mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. in ad...

objective: allogeneic transplantation with umbilical cord blood (ucb) in adult recipients is limited mainly by a low cd34+ cell dose. to overcome this shortcoming, human placenta as a novel source of human mesenchymal progenitor cell (mpc)- unrestricted somatic stem cells (ussc)- was incorporated in an attempt to expand cd34+ cells from ucb. to provide a similar environment in vitro, we coated ...

The transcriptional responses of drug treatments combined with a protein target prediction algorithm was utilised to associate compounds to biological genomic space. This enabled us to predict efficacy of compounds in cMap and LINCS against 181 databases of diseases extracted from GEO. 18/30 of top drugs predicted for leukemia (e.g. Leflunomide and Etoposide) and breast cancer (e.g. Tamoxifen a...

new blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ecs) which in turn give rise to primitive capillary network. human cord blood (hcb) contains large subsets of mononuclear cells (mncs) that can be differentiated into endothelial-like cells in vitro. human mononuclear progenitor cells were purified from fresh umb...

Endothelial progenitor cells (EPCs) and hematopoietic progenitor cells are recruited to ischemic regions, improving neovascularization. 1 and 2 integrins play a crucial role for progenitor cell homing to ischemic tissues. Integrin activity is regulated by chemokines and their respective G protein–coupled receptors. The phosphatidylinositol3-kinase catalytic subunit (PI3K ) is the PI3K isoform t...

dental tissues provide an alternate source of stem cells compared with bone marrow and have a similar potency as that of bone marrow derived mesenchymal stem cells. it has been established there are six types of dental stem cells: dental pulp stem cells, stem cells from human exfoliated deciduous teeth, stem cells from apical papilla, periodontal ligament stem cells, dental follicle progenitor ...

Sox2 regulates the self-renewal of multiple types of stem cells. Recent studies suggest it also plays oncogenic roles in the formation of squamous carcinoma in several organs, including the esophagus where Sox2 is predominantly expressed in the basal progenitor cells of the stratified epithelium. Here, we use mouse genetic models to reveal a mechanism by which Sox2 cooperates with microenvironm...
