During cell migration, forces generated by the actin cytoskeleton are transmitted through adhesion complexes to the substrate. To investigate the mechanism of force generation and transmission, we analyzed the relationship between actin network velocity an ...
Notch1 regulates neural stem cell (NSC) number during development, but its role in adult neurogenesis is unclear. We generated nestin-CreER(T2)/R26R-YFP/Notch1(loxP/loxP) [Notch1inducible knock-out (iKO)] mice to allow tamoxifen (TAM)-inducible elimination ...
Researches on neural differentiation using embryonic stem cells (ESC) require analysis of neurogenesis in conditions mimicking physiological cellular interactions as closely as possible. In this study, we report an air-liquid interface-based culture of hum ...
In vertebrates, face and throat structures, such as jaw, hyoid and thyroid cartilages develop from a rostrocaudal metameric series of pharyngeal arches, colonized by cranial neural crest cells (NCCs). Colinear Hox gene expression patterns underlie arch spe ...
Severe lesions of the rodent or human spinal cord lead to permanent paralysis of the legs. Here, we review novel evidences suggesting that interventions combining pharmacological and electrical stimulations of the spinal cord have a high potential to promo ...
BACKGROUND: Endoderm organ primordia become specified between gastrulation and gut tube folding in Amniotes. Although the requirement for RA signaling for the development of a few individual endoderm organs has been established a systematic assessment of i ...
Snail-type transcription factors (TFs) are found in numerous metazoan organisms and function in a plethora of cellular and developmental processes including mesoderm and neuronal development, apoptosis and cancer. So far, Snail-type TFs are exclusively kno ...
In animals, pigment cells are essential for coloration, as seen in feathers, fur, skin and eyes. In mammals, neural crest-derived melanocytes constitute the major population of pigment cells that is located mainly in the skin epidermis, as well as in hair ...
Intensive research over the past few years has provided evidence, that stress is a potent modulator of brain function and cognition. In particular cognitive and emotional processes have been shown to be susceptible to modulation by stress. Whereas acute st ...
Stress is known to be a potent modulator of brain function and cognition. While prolonged and/or excessive stress generally exerts negative effects on learning and memory processes, acute stress can have differential effects on memory function depending on ...
