Global transcriptome of bone marrow niche cells in homoestatis and human xenografts at late time points

ABSTRACT: We analysed the transcriptional signature in different niche cells extracted from the bone marrow of mice engrafted with human AML patient-derived samples or AML cell lines and compared it to the one of mice engrafted with human normal hematopoietic cells derived from cord blood or untransplanted mice

leukemia propagating cells rebuild an evolving niche in response to therapy

Project description:Residence of cancer-propagating cells (CPCs) within preferential microenvironmental niches has a major part in evading therapy. However, the nature of niches involved and the mechanisms protecting CPCs remain largely unknown. We addressed these issues in mouse transplantation models of acute lymphoblastic leukemia (ALL). When the engrafted leukemic cells substantially damaged adjacent vascular structures and endosteal linings in the bone marrow (BM), after chemotherapy small foci of CPCs were retained, surrounded by sheaths of supporting cells that comprise a novel niche. We investigated patients’ BM biopsies and found evidence of a similar process in patients receiving induction-therapy. The efficacy of chemotherapy was enhanced by interfering with the niche formation or niche-CPC interaction. We therefore identified a therapy-induced niche that protects CPCs. We used microarrays to compare the gene expression profile of ALL cell line (Nalm-6) from model (A0D) mice and rediduel cells from Ara-C treatment for 2 days (A2D) mice. Engrafted NALM-6-GFP+ cells from A0D mice and residual cells from A2D mice were flow sorted. Total RNA was isolated using RNeasy micro kit (Qiagen). Biotinylated cRNA was hybridized using HGU133Plus 2.0 GeneChip arrays (Affymetrix).

The bone marrow niche regulates redox and energy balance in leukemia stem cells

Project description:The Cxcr4-Cxcl12 axis has been postulated as a critical pathway dictating leukemia stem cell (LSCs) chemoresistance in AML due to its role in controlling cellular egress from the marrow. Nevertheless, the cellular source of Cxcl12 in the AML microenvironment and the mechanism by which Cxcl12 exert its protective role in AML in vivo remain unresolved. We have evaluated the functional role of Cxcl12 secreted by early mesenchymal stromal cells (MSCs) and osteolineage committed cells in acute myeloid leukemia (AML) maintenance in vivo. Our results demonstrate that early MSCs, in contrast to committed osteoblasts, are integral part of the MLL::AF9 derived AML niche and control LSCs maintenance through Cxcl12 secretion. Cxcl12 from MSCs regulates the oxidative state of LSCs and promotes energy metabolism. Furthermore, the protective role of the niche through the activation of the CXCL12-CXCR4 axis, may also represent a biological hallmark in human pediatric and adult AML, hence, reinforcing the notion that targeting the MSCs-derived CXCL12 may help eradicate leukemia.

A T-cell receptor targeting a shared neoantigen mediates elimination of primary human acute myeloid leukemia in vivo

Project description:This paper presents a T-cell receptor (TCR) reactive to the recurrent D835Y driver mutation in the FLT3 tyrosine-kinase domain. TCRFLT3D/Y-redirected T cells selectively eliminated primary human AML cells harboring the D835Y mutation in vitro and in vivo. The TCRFLT3D/Y cells rejected both CD34+ and CD34- AML in mice engrafted with primary leukemia from patients, reaching minimal residual disease negative levels, and eliminated primary CD34+ AML leukemia-propagating cells in vivo. Thus, T cells targeting a single shared mutation can provide efficient immunotherapy towards selective elimination of clonally involved primary AML cells in vivo.

Restoring bone marrow niche function rejuvenates aged hematopoietic stem cells by reactivating the DNA Damage Response [4]

Project description:The bone marrow (BM) niche comprised of BM endothelial cells (BMECs) and LepR+ mesenchymal stromal cells (MSCs), plays a critical role in preserving the fitness of hematopoietic stem cells (HSCs). Aging is associated with defects in the BM niche that impair their ability to support HSC activity. However, mechanisms underlying age-related defects in the BM niche remain poorly understood. In this study, we identify BM niche derived Netrin-1 (NTN1) as a critical regulator of BM niche cell fitness during aging. Conditional deletion of NTN-1 specifically within BM MSCs or BMECs of young mice resulted in premature aging phenotypes within the BM niche including increased vascular leakiness, hypoxia, DNA damage and adiposity. On the other hand, supplementation of aged mice with NTN1 resulted in restoration of these hallmark niche defects and a rejuvenation of HSC activity. Mechanistically, we identify NTN1 as a critical regulator of DNA Damage Response (DDR) within BM niche cells and HSCs. In this experiment, RNA Seq analysis was performed on HSCs derived from young mice (3 month old), PBS treated aged mice (18 month old), and NTN1 treated aged mice (18 month old), to characterize transcriptional alterations within HSCs during aging, and following NTN1 treatment of aged mice.
