Papel da imunofenotipagem por citometria de fluxo no diagnóstico diferencial das pancitopenias e das linfocitoses The role of flow cytometer-based immunophenotyping in the differential diagnosis of pancytopenia and of lymphocytosis

Revista Brasileira de Hematologia e Hemoterapia, 2009
A imunofenotipagem por citometria de fluxo (CMF) é atualmente uma ferramenta indispensável para o diagnóstico hematopatológico. Nos últimos anos muitos progressos foram alcançados em instrumentação, novos anticorpos e fluorocromos e programas de análise.

Quantitative Phase Imaging for Label-Free Analysis of Cancer Cells—Focus on Digital Holographic Microscopy

Applied Sciences, 2018
To understand complex biological processes, scientists must gain insight into the function of individual living cells. In contrast to the imaging of fixed cells, where a single snapshot of the cell’s life is retrieved, live-cell imaging allows ...

Comprehensive Phenotyping of T Cells Using Flow Cytometry

Cytometry Part A, 2019
The T cell compartment can form a powerful defense against extrinsic (e.g., pathogens) and intrinsic danger (e.g., malignant cells). At the same time, specific subsets of T cells control this process to keep the immune system in check and prevent ...

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1

Molecular Oncology, EarlyView.
Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

CytoNorm: A Normalization Algorithm for Cytometry Data

Cytometry Part A, 2019
High‐dimensional flow cytometry has matured to a level that enables deep phenotyping of cellular systems at a clinical scale. The resulting high‐content data sets allow characterizing the human immune system at unprecedented single cell resolution ...

The critical role of DNA damage‐inducible transcript 4 (DDIT4) in stemness character of leukemia cells and leukemia initiation

Molecular Oncology, EarlyView.
Stemness properties, including quiescence, self‐renewal, and chemoresistance, are closely associated with leukemia relapse. Here, we demonstrate that DNA damage‐inducible transcript 4 (DDIT4) is induced in the hypoxic bone marrow niche and is essential for maintaining the stemness of AML1‐ETO9a leukemia cells.

Fluctuation of Information Entropy Measures in Cell Image

Entropy, 2017
A simple, label-free cytometry technique is introduced. It is based on the analysis of the fluctuation of image Gray Level Information Entropy (GLIE) which is shown to reflect intracellular biophysical properties like generalized entropy.

Magnetic Twisting Cytometry

Cold Spring Harbor Protocols, 2011
INTRODUCTIONThis protocol provides the general steps for magnetic twisting cytometry (MTC). MTC is an active microrheology method well-suited to measuring the mechanical properties of the individual adherent cells. Specialized equipment is required for producing the magnetic fields used in this technique.
