Characterization of the gut-bone marrow axis through bile acid signaling
Communication between the intestine and other organs such as the lungs, brain or bones is mediated by several metabolites, like short-chain fatty acids or bile acids, that relay information about nutritional and microbiota status. Bile acids are endogenous ...
EPFL2024Disruption of stem cell niche-confined R-spondin 3 expression leads to impaired hematopoiesis
Freddy Radtke, Ute Koch, Jialin Zhang, Soufiane Boumahdi
Self-renewal and differentiation of stem and progenitor cells are tightly regulated to ensure tissue homeostasis. This regulation is enabled both remotely by systemic circulating cues, such as cytokines and hormones, and locally by various niche-confined f ...
ELSEVIER2023Novel quantitative bioengineered tools to track human bone marrow niche cellular constituents in health and disease
Acute leukemia has a high mortality rate of approximately 50%, and current methods are not effective in predicting disease progression and relapse. To improve our understanding of hematopoiesis and develop new markers for predicting disease relapse in dead ...
EPFL2023New approaches to uncover the minimally functional hematopoietic niche using the adipocytic differentiation axis: pharmacological modulation and adrenal niche induction
Hematopoietic Stem and Progenitor Cells (HSPCs) reside in their niche, a structure that regulates the balance of cellular quiescence, self-renewal and commitment towards differentiated cells. This highly plastic niche is formed by several cellular players, ...
EPFL2022Inhibition of SRC-mediated integrin signaling in bone marrow niche enhances hematopoietic stem cell function
Interaction with microenvironmental factors is crucial for the regulation of hematopoietic stem cell (HSC) function. Stroma derived factor (SDF)-1 alpha supports HSCs in the quiescent state and is central to the homing of transplanted HSCs. Here, we show t ...
CELL PRESS2022Quantitative approaches to unravel bone marrow adipocyte site-specificity and its implication in hematopoiesis
Josefine Catharina Pedersen Tratwal
Over the last decade, bone marrow (BM) adipose tissue (BMAT) has emerged as a distinct adipose depot with unique metabolic properties and effects both in homeostasis and in the progression of disease.
We provide a first comprehensive review of existing an ...
EPFL2020Reporting Guidelines, Review of Methodological Standards, and Challenges Toward Harmonization in Bone Marrow Adiposity Research. Report of the Methodologies Working Group of the International Bone Marrow Adiposity Society
Olaia Maria Naveiras Torres-Quiroga, Josefine Catharina Pedersen Tratwal
The interest in bone marrow adiposity (BMA) has increased over the last decade due to its association with, and potential role, in a range of diseases (osteoporosis, diabetes, anorexia, cancer) as well as treatments (corticosteroid, radiation, chemotherapy ...

Vasco Ledebur de Antas de Campos
The procedure-associated mortality rate of bone marrow transplantations (BMT) remains close to 25%. The BMT is therefore only indicated for life-threatening diseases, with no replacement of this technology to be expected in the foreseeable future. Modest i ...
EPFL2019Modeling hematopoietic stem cell dynamics in bioengineered niches
Bone marrow transplantation is a well-established medical procedure for the treatment of various hematologic diseases. However, the relatively low number of hematopoietic stem cells (HSCs) that can be harvested, especially from umbilical cord blood, limits ...
EPFL2019Bioengineering human bone marrow models to elucidate the triggers of the stem cell niche
The bone marrow (BM) microenvironment, or niche, significantly affects behaviors of its resident stem cell populations. Disruptions in the BM niche contribute to a number of severe clinical pathologies. Discovery of novel therapeutic strategies for BM-rela ...
