The results of studies conducted by Carow, Hangoc, and Broxmeyer in 1993 reveal that the CFU-GEMM can be classified as a stem cell due to its high replating efficiency in the presence of certain growth factors and cytokines. (wikipedia.org)

A team of researchers collected blood samples from National Aeronautics and Space Administration (NASA) astronauts who flew space shuttle missions between 1998 and 2001. (spaceref.com)

It has been suggested that eosinophils do not derive from the common myeloid progenitor in humans. (wikipedia.org)

and 5,000 cells showed a linear relationship between the level of engraftment, as measured by FACS for CD45, and cell dose. (ox.ac.uk)

By studying these immature blood cells, he aims to better understand what causes these diseases, as well as the mechanisms by which they sometimes become resistant to standard therapies. (missionbio.com)
Taken together, these data challenge the current view that the thymus is colonized by a lymphoid-restricted progenitor and provide evidence that a more immature precursor population with lymphoid and myelomonocytic potential is actually seeding the human postnatal thymus. (ashpublications.org)
Hematopoietic stem cells are immature cells that develop into all types of blood cells. (differencebetween.com)
consist of predominantly immature, poorly differentiated cells (usually blast forms). (msdmanuals.com)

Lymphoid cells include T cells, B cells, innate lymphoid cells, and natural killer cells. (differencebetween.com)

Among all cancerous cells, a few act as stem cells that reproduce and sustain the tumor, much like stem cells normally renew and sustain our organs and tissues. (atlasantibodies.com)
Progenitor cells are an intermediary step in the development of mature cells in tissues, organs, blood, and the central nervous system. (differencebetween.com)
Therefore, progenitor cells are necessary for repairs and to maintain tissues after an injury. (differencebetween.com)
They can create new tissues and even whole organs from a few stem cells. (differencebetween.com)
Totipotent stem cells contain all the constituents necessary to produce a living being, given that these cells can supply all embryonic and extraembryonic tissues required for proper growth (Can/Hematol 2008). (papersowl.com)
The term "oncotarget" encompasses all molecules, pathways, cellular functions, cell types, and even tissues that can be viewed as targets relevant to cancer as well as other diseases. (oncotarget.com)
