To understand the cellular and molecular mechanisms regulating cytogenesis within the neocortical ventricular zone, we examined at high resolution the spatiotemporal expression patterns of Ngn2 and Tbr2. Individually DiI-labeled daughter cells were tracked from their birth in slice cultures and immunostained for Ngn2 and Tbr2. Both proteins were initially(More)
Recent imaging studies revealed that neocortical neurons undergo multiple modes of migration, but their earliest morphologies and behaviors remain unclear. We found that some neurons generated at the ventricular surface initially adopt a pin-like morphology and generally lack a leading process. During abventricular nuclear movement, their centrosomes are(More)
Interleukin-10 (IL-10) is a unique cytokine that is thought to be a potent immunostimulatory and immunosuppressive factor. The aim of this study was to investigate IL-10 expression in colorectal cancer, and clarify its relationship to the clinicopathological findings and prognosis. Tissue samples were collected from 92 patients with colorectal cancer and(More)
The small GTPase Rac regulates neuronal behavior, but whether it also functions in neural progenitor cells has not yet been explored. Here we report that Rac contributes to the regulation of nuclear migration in neocortical progenitor cells. Rac1 is expressed by progenitor cells in a unique spatiotemporal pattern. Cross-sectional immunohistochemical(More)
To understand the morphogenetic dynamics of the inner surface of the embryonic pallial (neocortical) wall, we immunohistochemically surveyed the cellular endfeet facing the lateral ventricle and found that the average endfoot area was minimal at embryonic day (E)12 in mice. This endfoot narrowing at E12 may represent a change in the mode of cell production(More)
