Topological defect launches 3D mound in the active nematic sheet of neural progenitors [PDF]
, 2016 Cultured stem cells have become a standard platform not only for regenerative medicine and developmental biology but also for biophysical studies. Yet, the characterization of cultured stem cells at the level of morphology and macroscopic patterns resulting from cell-to-cell interactions remain largely qualitative, even though they are the simplest ...

Recognition and reconstruction of cell differentiation patterns with deep learning [PDF]
arXiv, 2022 Cell lineage decisions occur in three-dimensional spatial patterns that are difficult to identify by eye. There is an ongoing effort to replicate such patterns using mathematical modeling. One approach uses long ranging cell-cell communication to replicate common spatial arrangements like checkerboard and engulfing patterns.

Multi-Compartmental Biomaterial Scaffolds for Patterning Neural Tissue Organoids in Models of Neurodevelopment and Tissue Regeneration [PDF]
J. Tissue Engineering 2016; 7:1-8, 2016 Biomaterials are becoming an essential tool in the study and application of stem cell research. Various types of biomaterials enable three-dimensional (3D) culture of stem cells, and, more recently, also enable high-resolution patterning and organization of multicellular architectures.

Introduction to Neural Stem Cells [PDF]
Stroke, 2007 Neural stem cells self-renew and give rise to neurons, astrocytes and oligodendrocytes. These cells hold great promise for neural repair after injury or disease. However, a great deal of information needs to be gathered before optimally using neural stem cells for neural repair.

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

FEBS Letters, EarlyView.B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Sildenafil enhances neurogenesis and oligodendrogenesis in ischemic brain of middle-aged mouse. [PDF]
PLoS ONE, 2012 Adult neural stem cells give rise to neurons, oligodendrocytes and astrocytes. Aging reduces neural stem cells. Using an inducible nestin-CreER(T2)/R26R-yellow fluorescent protein (YFP) mouse, we investigated the effect of Sildenafil, a phosphodiesterase
