Stem cells in the bone marrow give rise to all of your different blood cells. (medlineplus.gov)
Due to the smaller number of stem cells, blood counts take much longer to recover. (medlineplus.gov)
The stem cells travel through the blood into the bone marrow. (medlineplus.gov)
Leukapheresis -- First, the donor is given several days of shots to help stem cells move from the bone marrow into the blood. (medlineplus.gov)
The part of white blood cells that contains stem cells is then separated in a machine and removed to be later given to the recipient. (medlineplus.gov)
The red blood cells are returned to the donor. (medlineplus.gov)
Storage of bone marrow or blood leukemic cells in biobanks is strongly recommended. (cancercentrum.se)

The identification of cytogenetic, molecular, and clinical factors impacting on outcome at acute myeloid leukemia (AML) diagnosis improved risk stratification [ 1 , 2 ]. (oncotarget.com)
Various factors including age, sex, performance status (PS), disease status, cytogenetic risk, donor type, graft source, sex mismatch between the donor and the recipient, and year of transplantation were all shown to impact OS 2 . (apbmt.org)
Criteria for diagnosis of MDS consist of anemia, thrombocytopenia, or neutropenia that persist for six months or longer, dysplasia greater than 10% in at least one bone marrow cell lineage, and MDS associated clonal cytogenetic abnormalities or molecular markers. (standardofcare.com)

In the study, patients with active, relapsed, refractory AML are randomized 1:1 to receive either apamistamab conditioning therapy and allogeneic HCT or conventional care. (onclive.com)
Lately, CAR-NK cell therapies have also come into focus as novel therapeutic options to address hurdles related to CAR-T cell therapies, such as therapy-induced side effects. (nature.com)
Most CAR-T cell-based gene therapy products that are under clinical evaluation consist of autologous enriched T cells, whereas CAR-NK cell-based approaches can be generated from allogeneic donors. (nature.com)
An autologous CAR-T or NK cell therapy comprises several steps as shown in Fig. 1 . (nature.com)
Patients undergo lymphodepletion therapy 3-5 days prior to CAR T cell infusion and receive anti-CD33 CAR T-cells intravenously (IV) on day 0. (survivornet.com)

Clonal hematopoietic stem cell disorders characterized by ineffective hematopoiesis and peripheral cytopenias. (standardofcare.com)
There is clonal proliferation of malignant hematopoietic stem cells, dysregulated cellular differentiation, and compromised tissue function. (standardofcare.com)
The clonal outgrowth of mutant stem cells favors and abnormal hematopoietic stem cell niche. (standardofcare.com)

The donor first has to be treated with G-CSF, and then the stem cells can only be harvested a couple of days after the donor since time is needed for the donor's body to form more stem cells and transport these cells into the bloodstream. (differencebetween.net)
A bone marrow transplant is when stem cells are removed from a donor's bone marrow for transplant into a patient. (differencebetween.net)

Minimal residual disease assessment in childhood acute lymphoblastic leukaemia: a Swedish multi-centre study comparing real-time polymerase chain reaction and multicolour flow cytometry. (smw.ch)

This is when stem cells that are obtained from the bloodstream or umbilical cord of a donor are used for transplant into a patient. (differencebetween.net)
A stem cell transplant is when stem cells are harvested from the bloodstream or the umbilical cord. (differencebetween.net)
Stem cells are removed from a newborn baby's umbilical cord right after birth. (medlineplus.gov)

75 years old) followed by cytarabine consolidations and/or allogeneic stem-cell transplantation (ASCT). (dovepress.com)

The FLAMSA protocol is most often used as an induction part of a reduced-intensity conditioning regimen for patients eligible to undergo an allogeneic stem cell transplant. (wikipedia.org)

Acute myeloid leukemia (AML) is a malignant disease of the bone marrow in which hematopoietic precursors are arrested in an early stage of development. (medscape.com)
The paradox is that the mutation provides advantage at the stem cell level and progenitor cells, with a disadvantage at the level of hematopoietic precursors. (standardofcare.com)

Quantitating the CD34+ cell population can also be useful during mobilization as well as for determining the optimal timing of apheresis sessions to make sure that enough CD34+ cells have been harvested. (bdbiosciences.com)

How I treat measurable (minimal) residual disease in acute leukemia after allogeneic hematopoietic cell transplantation. (nih.gov)

2 Evaluation of harvest adequacy requires the use of reliable progenitor cell assays and this is usually achieved by CD34 cell counting using flow cytometry. (bdbiosciences.com)
Flow cytometric applications for CD34+ cell identification and enumeration provide a rapid, quantitative and reproducible method to evaluate the progenitor cell population. (bdbiosciences.com)
