  • B-cells arise from a lymphoid progenitor, while macrophages come from a myeloid progenitor. (innovations-report.com)
  • They observed that impairing Ythdf2 function did not alter the types of cells that were subsequently produced, nor did it lead to increased blood cell malignancies. (scitechdaily.com)
  • Linheng Li believes that this approach could potentially be applied to other types of adult stem cells, which may lead to increasing the number of adult stem cells available for treating patients. (scitechdaily.com)
  • What we've shown is that we can generate a cell that can form all the different types of blood cells. (scitechdaily.com)
  • Together with other published results, these observations blur the concept of fixed cell types and provide new insights concerning potential uses for adult stem cells. (innovations-report.com)
  • we also need to ensure that the lab-created blood stem cells can continue to function properly by making all blood cell types when transplanted. (medicalxpress.com)
  • Our method, which exposes blood stem cells to the small molecules and also inserts an active MLLT3 gene, created blood stem cells that integrated well into mouse bone marrow , efficiently produced all blood cell types and maintained their self-renewing ability. (medicalxpress.com)
  • There are several types of stem cells that can be used for different purposes. (healthline.com)
  • They make new red blood cells, white blood cells, and other types of blood cells. (healthline.com)
  • Adult stem cells can't differentiate into as many other types of cells as embryonic stem cells can. (healthline.com)
  • They can differentiate into all types of specialized cells in the body. (healthline.com)
  • Ensuring a proper blood supply is always readily available, however, is a whole other challenge, thanks to the presence of ultra-rare blood types and the inconvenience associated with blood donation. (extremetech.com)
  • Scientists have transfused lab-made red blood cells into a human volunteer in a world-first trial that experts say has major potential for people with hard-to-match blood types or conditions such as sickle cell disease. (cnn.com)
  • In stem cell science, directing stem cells to become any of the hundreds of cell types that make up the human body is often as much art as science. (wisc.edu)
  • Other approaches require mixing and co-culture of other cell types," explains Shusta. (wisc.edu)
  • Blood stem cells in the bone marrow provide a lifelong replenishment of the different cell types making up the blood system. (eurekalert.org)
  • When stem cells divide, they generate different types of blood cells, like white blood cells. (time.com)
  • That extraction process used to mean drilling deep into their hip bones and using an extra-long needle to pull out bone marrow, which holds the cells that can develop into all types of blood cells. (popsci.com)
  • Stem cells are undifferentiated cells that have the potential to become one of 200 types of cells in the body, including blood, nerve, muscle, heart, glandular, and skin cells. (msdmanuals.com)
  • These stem cells can produce different types of blood cells. (msdmanuals.com)
  • Stem cells are nonspecific cells with powerful self-regeneration properties and they are capable of organizing other cell types in the body. (bvsalud.org)
  • There are basically two types of stem cells: embryonic and somatic (or adult). (bvsalud.org)
  • If we could cure sickle cell disease in a safe and effective way, such as a pill that can reverse the disease, that would be a home run. (medlineplus.gov)
  • The main advance is we now have a fully defined process that uses small molecules to guide cells through the developmental process," says University of Wisconsin-Madison Professor of Chemical and Biological Engineering Sean Palecek of the method that substitutes chemical factors for cells to push stem cells to become the brain endothelial cells that compose the blood-brain barrier. (wisc.edu)
  • The new method, he adds, will also allow industry to scale up production of the brain endothelial cells for drug discovery. (wisc.edu)
  • Bone marrow appears to contain three stem cell populations: hematopoietic stem cells, stromal stem cells and endothelial precursor cells. (bvsalud.org)
  • The hematopoietic stem cells in the bone marrow continuously ensure that the blood system is supplied with new cells throughout life and that in stressful conditions, such as infections, inflammations or bleeding, the production of the required blood cells can then be initiated immediately. (idw-online.de)
  • Red blood cells typically last about 120 days, but a transfusion from a standard donation contains cells that are a variety of ages because the bone marrow continuously makes these cells. (cnn.com)
