Mesenchymal stromal cells (MSC) are a rare, heterogeneous and multipotent population that can be isolated from several tissues. MSC were originally discovered in the bone marrow and studied for their capacity to maintain hematopoietic cells. We will describe here methods to isolate, culture, and bank MSC from human bone marrow. Then, characterization protocols by flow cytometry, clonogenic assays and doubling time evaluation will be developed. Finally, in vitro MSC culture and differentiation into osteoblasts, adipocytes, and chondrocytes will be explained. Thus, this chapter will detail all bases to work on MSC with consensus and clear methods and protocols.

The objective of this study was to evaluate the concentration and integrity index of circulating cell-free DNA (ccf-DNA) as biomarkers for the detection and monitoring of minimal residual disease (MRD) in pediatric patients with B-cell acute lymphoblastic leukemia (B-ALL). Comparison with a validated methodology for the quantification of monoclonal rearrangements of the IGH gene was made. Peripheral blood and bone marrow samples were collected from 10 pediatric patients with B-ALL at diagnosis, remission, and maintenance phases.

Background: Neurotraumatic conditions, such as spinal cord injury, brain injury, and neurodegenerative conditions, such as amyotrophic lateral sclerosis, pose a challenge to the field of rehabilitation for its complexity and nuances in management. For decades, the use of cell therapy in treatment of neurorehabilitation conditions have been explored to complement the current, mainstay treatment options; however, a consensus for standardization of the cell therapy and its efficacy has not been reached in the medical community. This study aims to provide a comparative review on the very topic of cell therapy use in neurorehabilitation conditions in an attempt to bridge the gap in knowledge.

Two types of plasmacytoid dendritic cell (pDC) proliferation disease are acknowledged so far by the 5th edition of the World Health Organization Classification of Haematolymphoid Tumors: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) and mature pDC proliferation associated with myeloid neoplasms (MPDCP) in which pDC is part of the malignant clone. We aim to investigate pDC proliferation associated with non-myeloid acute leukemia (AL). A retrospective analysis of all cases admitted in our center with a diagnosis of non-myeloid AL from September 2020 to April 2023 was performed to select cases with pDCs greater than 2% of bone marrow by flow cytometry (FCM).

Lymphoma-associated hemophagocytic lymphohistiocytosis (LA-HLH) is a life-threatening hyperinflammatory syndrome, and hierarchical management based on a prognostic model is important. The endothelial activation and stress index (EASIX) score has demonstrated prognostic utility in recipients of allogeneic stem cell transplantation and chimeric antigen receptor (CAR) T-cell therapy. However, its role in LA-HLH remains unestablished.

Chronic myelomonocytic leukemia (CMML) is an aggressive hematologic neoplasm characterized by an expansion of CD123 monocytes and plasmacytoid dendritic cells (pDCs). pDC bone marrow clusters in CMML have been associated with higher rates of acute myeloid leukemia transformation. We evaluated tagraxofusp, a CD123-targeted therapy, in a phase 1/2 trial for patients with CMML.
