Advances and challenges in storage, transplantation, expansion and homing of Umbilical Cord Blood Hematopoietic Stem Cells (UCB-HSCs)
Abstract Background and Objectives Umbilical cord blood hematopoietic stem cells (UCB-HSCs) have high potential capabilities in the treatment of hematological and non-hematological disorders. Awareness of biology, self-renewal, homing, expansion, storage, and transplantation can lead to optimal use of these cells. Materials and Methods In this Review article in order to investigate the adv...
متن کاملMild hypoxia and human bone marrow mesenchymal stem cells synergistically enhance expansion and homing capacity of human cord blood CD34+ stem cells
Objective(s): Cord blood (CB) is known as a valuable source of hematopoietic stem cells (HSC). Identifying strategies that enhance expansion and maintain engraftment and homing capacity of HSCs can improve transplant efficiency. In this study, we examined different culture conditions on ex vivo expansion and homing capacity of CB-HSCs. Materials and Methods: In this study, 4-5 different units o...
متن کاملT-Lymphocyte Homing: An Underappreciated yet Critical Hurdle for Successful Cancer Immunotherapy
Advances in cancer immunotherapy have offered new hope for patients with metastatic disease. This unfolding success story has been exemplified by a growing arsenal of novel immunotherapeutics, including blocking antibodies targeting immune checkpoint pathways, cancer vaccines, and adoptive cell therapy (ACT). Nonetheless, clinical benefit remains highly variable and patient-specific, in part, b...
متن کاملEngineering lymph node homing of ex vivo-expanded human natural killer cells via trogocytosis of the chemokine receptor CCR7.
Natural killer (NK) cells have gained significant attention in adoptive immunotherapy for cancer. Consequently, novel methods of clinical-grade expansion of NK cells have emerged. Subsets of NK cells express a variety of chemokine receptors. However, to expand the scope of adoptively transferred NK cell homing to various malignancies, expression of corresponding chemokine receptors on NK cells ...
متن کاملMelatonin Pretreatment Enhances the Homing of Bone Marrow-derived Mesenchymal Stem Cells Following Transplantation in a Rat Model of Liver Fibrosis
Background: Bone marrow-derived mesenchymal stem cells (BMMSCs) transplantation has been considered as a promising milestone in liver fibrosis treatment. However, low amounts of homing are a major obstacle. We aimed to investigate the role of melatonin pretreatment in BMMSC homing into experimental liver fibrosis. Methods: BMMSCs were obtained, grown, propagated and preconditioned with 5 µ...
