Chimeric antigen receptor (CAR)-T cell therapies are on the verge of becoming powerful immunotherapeutic tools for combating hematological diseases confronted with pressing medical needs. (nature.com)
In this review, we are going to take a closer look at the commercial CAR-T cell therapies, as well as on CAR-T and CAR-NK cell products, which are currently under evaluation in clinical trials, that are being conducted in Germany. (nature.com)
The specific effect on bone marrow fibrosis of JAK2 inhibition, and other rationally based therapies currently being evaluated in myelofibrosis, has yet to be fully elucidated. (haematologica.org)
We therefore briefly discuss differences found in subsets of human bmMSCs and in MSCs isolated from some other sources and touch upon how this could be utilized for cell-based therapies. (hindawi.com)
Therefore, we aimed to identify cell surface proteins specifically expressed on NPM1)-mutated AML cells, allowing for potential targeting with antibody-based therapies. (lu.se)

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)
Organ Transplantation.2 These Guiding Principles - whose emphases include voluntary donation, noncommercialization, genetic relation of recipients to donors and a preference for cadavers over living donors as sources - have considerably influenced professional codes, national, state and provincial legislation, and the policies of intergovernmental organizations. (who.int)
Allogeneic hematopoietic stem cell transplantation is limited mainly by lack of histocompatible donors. (msdmanuals.com)
Donor CTLA-4 genotype influences clinical outcome after T cell-depleted allogeneic hematopoietic stem cell transplantation from HLA-identical sibling donors. (cdc.gov)

Today, more than 50 years after the first successful bone marrow transplantation, clinical application of hematopoietic stem cells is a routine procedure, saving the lives of many every day. (hindawi.com)
Overall, this evidence has suggested that progenitor cell treatment may be a promising intervention, but robust data on clinical outcomes are lacking. (southcarolinablues.com)
In principle, transplantation of mesenchymal progenitor cells would attenuate or possibly correct genetic disorders of bone, cartilage and muscle, but clinical support for this concept is lacking. (nih.gov)
This computational approach to the haematopoietic system is novel and provides insight into the dynamics and the nature of possible solutions, with potential applications in both fundamental and clinical research. (lu.se)

Abnormal mutations in stem cells were found accompanying with the occurrence of MPN. (biomedcentral.com)
Relevance: Acute leukemia arises because abnormal white cell precursors proliferate within special growth zones within the bone marrow. (cancer.gov)

The success in these studies was related in part to the selective growth of genetically altered/corrected progenitors. (eyesoftheelephants.com)
eg, bone, bone marrow, and skin grafts) Genetically identical (syngeneic [between monozygotic twins]) donor tissue (isografts) Genetically. (msdmanuals.com)

When specific tissue or organ damage occurs, these cells can rapidly generate new cells of the desired type to facilitate the healing process. (thenoveldifference.com)
The tumor will rapidly recur if the therapy eliminates cancer cells but spares a significant population of the cancer stem cells. (hoajonline.com)
Mature, differentiated cells that accompany the hematopoietic stem cells, disappear rapidly after transplantation as they lack the ability to self-renew. (ca.gov)
At steady-state, HSC infrequently divide and slowly but continuously spawn rapidly dividing progenitor cells. (digs-bb.de)
