Modeling hematopoietic stem cell dynamics in bioengineered niches

Sonja Giger

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 ...

Enhanced understanding of normal and malignant hematopoiesis pathways should facilitate the development of effective clinical treatment strategies for hematopoietic malignancies. Nuclear receptor corepressor 1 (NCoR1) has been implicated in transcriptional ...

AMER SOC HEMATOLOGY2019

Hematopoietic stem cells (HSCs) are responsible for the continuous production of all blood cells. This unique ability has made it possible to successfully use HSCs in the clinical setting to remedy various blood disorders. However, despite six decades of r ...

Identification of Oxidative Stress in Red Blood Cells with Nanoscale Chemical Resolution by Infrared Nanospectroscopy

Giovanni Dietler, Giovanni Longo, Francesco Simone Ruggeri

During their lifespan, Red blood cells (RBC), due to their inability to self-replicate, undergo an ageing degradation phenomenon. This pathway, both in vitro and in vivo, consists of a series of chemical and morphological modifications, which include devia ...

Label-Free Optofluidic Nanobiosensor Enables Real-Time Analysis of Single-Cell Cytokine Secretion

Hatice Altug, George Coukos, Xiaokang Li, Maria Soler Aznar

Single-cell analysis of cytokine secretion is essential to understand the heterogeneity of cellular functionalities and develop novel therapies for multiple diseases. Unraveling the dynamic secretion process at single-cell resolution reveals the real-time ...

Molecular landscapes of human hematopoietic stem cells in health and leukemia

Cyrille Dunant

Blood cells are organized as a hierarchy with hematopoietic stem cells (HSCs) at the root. The advent of genomic technologies has opened the way for global characterization of the molecular landscape of HSCs and their progeny, both in mouse and human model ...

ESCRT proteins restrict constitutive NF-kappa B signaling by trafficking cytokine receptors

Because signaling mediated by the transcription factor nuclear factor kappa B (NF-kappa B) is initiated by ligands and receptors that can undergo internalization, we investigated how endocytic trafficking regulated this key physiological pathway. We deplet ...

Deciphering Metabolic Regulation of Hematopoietic Stem Cell Fate

Mukul Girotra

Hematopoietic stem cells (HSCs) are responsible for life-long production of all mature blood cells. This unique characteristic makes them an ideal candidate for cell-based therapies to treat various hematological malignancies. Their extensive use in the cl ...

Endocrine hormones and local signals during the development of the mouse mammary gland

Cathrin Brisken, Dalya Ataca

Most of mammary gland development occurs postnatally under the control of female reproductive hormones, which in turn interact with other endocrine factors. While hormones impinge on many tissues and trigger very complex biological responses, tissue recomb ...

Red Blood Cell Aging During Storage, Studied Using Optical Tweezers Experiment

Sylvia Jeney, Hanieh Mohammadi

This paper presents experimental and numerical studies of erythrocyte stretching, with a focus on the aging of red blood cells in an in vitro environment during storage. The experimental studies were performed using optical tweezers. The laser beam was use ...
