Results Eleven types of hematopoietic precursors and mature cells in erythroid and lymphoid lineage at different developmental stages were identified and documented through cytological description and morphometry in head kidneys of both the species. (caluniv.ac.in)

Within the bone marrow the red cell is derived from a primitive precursor, or erythroblast, a nucleated cell in which there is no hemoglobin. (assemblymade.com)

Built upon scDiffCom, scAgeCom is an atlas of age-related cell-cell communication changes covering 23 mouse tissues from 58 single-cell RNA sequencing datasets from Tabula Muris Senis and the Calico murine aging cell atlas. (nature.com)
scRNA-seq on murine hematopoietic stem cells (HSC) and their progeny MPP1 separated the cells into 3 main clusters with distinct features: active, quiescent, and an un-characterized cluster. (nih.gov)
Disruption of murine leads to embryonic lethality seen as a a major lack of bloodstream cells and reductions in hematopoietic precursors (22, 23). (researchhunt.com)

[ 3 ] The 2016 revision of the World Health Organization (WHO) classification of myeloid neoplasms and acute leukemia continued to recognize pure erythroid leukemia but eliminated the erythroid/myeloid type of acute erythroleukemia. (medscape.com)
Cases previously classified as erythroid/myeloid subtype, based on the 2008 WHO classification, are currently categorized either as myelodysplastic syndrome with excess blasts or acute myeloid leukemia, not otherwise specified. (medscape.com)
We identify a mutation (D262N) in the erythroid-affliated transcriptional repressor GFI1B, in an acute myeloid leukemia (AML) patient with antecedent myelodysplastic syndrome (MDS). (lu.se)
We demonstrate here that GSK-3 maintains the MLL leukemia stem cell transcriptional program by promoting the conditional association of CREB and its coactivators TORC and CBP with homedomain protein MEIS1, a critical component of the MLL-subordinate program, which in turn facilitates HOX-mediated transcription and transformation. (stanford.edu)
An increased M:E ratio (6:1) may be seen in infection, chronic myelogenous leukemia or erythroid hypoplasia. (assemblymade.com)
Leukemia control cells are the AZD1080 KIAA0901 initial reported kind of tumor control cells [5]. (immune-source.com)
10% of cells), or acute myeloid leukemia. (dermatologyadvisor.com)
RUNX1-positive leukemia cells in preclinical models. (lu.se)

Mutations in TET2, other epigenetic regulators, and other regulators of cytokine signaling are not specific to the classic myeloproliferative neoplasms (MPNs) but may influence prognosis and play roles in hematopoietic stem cell (HSC) dysregulation and progression to accelerated or blast-phase disease. (oncohemakey.com)
Several studies have attempted to explore direct effects of Epo on tumor cells and the possible mechanisms for Epo-mediated tumor progression, but the data are still controversial. (cancer8.info)

OBJECTIVE: Polycythemia Vera (PV) is a myeloproliferative neoplasm characterized by the overproduction of red blood cells. (bvsalud.org)
LMO2 protein expression has been noted in diffuse large B-cell lymphoma, the most common adult non-Hodgkin's lymphoma, as well as follicular lymphoma, a neoplasm derived from germinal center B-cells that accounts for a number of cases of non-Hodgkin's lymphomas. (genomeme.ca)
PV is a myeloproliferative neoplasm (MPN) of the bone marrow characterized by an overproduction of erythrocytes and often other blood cells. (cdc.gov)

In this context, an appealing approach is based on the exploitation of decellularized tissues as biological matrices to be colonized by the appropriate cell types to regenerate the desired organs. (bvsalud.org)
In mammals, O 2 is transported to tissues bound to the hemoglobin contained within circulating red cells. (mhmedical.com)
Tabula Muris is a compendium of single cell transcriptome data from the model organism Mus musculus , containing nearly 100,000 cells from 20 organs and tissues. (ucsc.edu)

In the bone marrow, the first morphologically recognizable erythroid precursor is the pronormoblast. (mhmedical.com)

However, Ueno and Weissman provided the earliest contradiction to the hemangioblast theory when they saw that distinct ES cells mixed into a blastocyst resulted in more than 1 ES cell contributing to the majority of the blood islands found in the resultant embryo. (wikipedia.org)

Erythroleukemia shares clinical and pathologic features with myelodysplastic syndromes , especially with erythroid-predominant myelodysplastic syndromes. (medscape.com)

The mutations arise later in life and are confined to hematopoietic precursor cells in bone marrow and myeloid cells (e.g., neutrophils and monocytes) in peripheral blood. (nejm.org)

These results table the SPI1-GFI1B transcriptional network as an important regulatory axis in AML as well as in the development of erythroid versus myelomonocytic cell fate. (lu.se)

When the bone marrow hematopoietic cells are mostly clonally derived cells, the disease is clinically manifested as cytopenia and morphologic dysplasia. (standardofcare.com)
