Anatomy and Cell BiologyCell Biology



We have been studying how the mammalian brain is constructed (Fig. 1). Structures of the central nervous system including the brain, spinal cord and retina are formed through multiple steps of cellular events. First, neural stem/progenitor cells divide to give rise to neurons. Then, young neurons migrate and find appropriate positions to settle. Finally, post-migratory neurons make connections with other neurons to establish neural circuit. Understanding of the basic mechanisms underlying these brain-forming events is important to elucidate pathological mechanisms of neurological diseases and to develop regenerative treatment methods against brain damages. One of our main strategies is live imaging using fluorescent microscopy. To experimentally ask how cells’ proliferative or migratory behaviors are regulated, we also carry out various experiments by which cell-intrinsic or cell-extrinsic factors are manipulated in culture or in vivo.

Research Projects

1. Systems-biological study to ask how the neuroepithelium is formed and three-dimensionally maintained by efficient assembly of heterogeneously moving cells (Miyata group).


i) Cell biological study to elucidate mechanisms underlying the formation of pseudostratified neuroepithelial structure (Shinoda, Nagasaka, Miyata)
Neural progenitor cells (also called neuroepithelial cells, radial glia, apical progenitors) are highly elongated connecting the apical (ventricular) and the basal (pial) surfaces of developing brain walls (Fig. 2)(Miyata et al., 2001: http://www.sciencedirect.com/science/article/pii/S0896627301004202). They move nuclei/somata in a cell cycle-dependent manner (apically during G2 phase, basally during G1 phase, with cell division at the apical surface). This is called interkinetic nuclear migration (INM) (reviewed in Miyata et al., 2015) (http://journal.frontiersin.org/article/10.3389/fncel.2014.00473/full). This project asks how movements of different cells within the neuroepithelium are coordinated.

ii) Study to elucidate mechanisms underlying the apicobasally elongated morphology of neural progenitor cells (Watanabe, Miyata).
We are asking cell-intrinsic and cell-extrinsic mechanisms that are potentially involved in the elongated morphology of neural progenitor cells.


iii) Measurement and simulation of mechanical properties of neural progenitors (Nagasaka, Shinoda, Miyata)
We are quantitatively measuring mechanical properties of progenitor cells using atomic force microscopy and other methods.

iv) Mechanical factors that neural progenitors sense and respond to (Kawasoe, Saito, Miyata)
Recently, we found that overcrowded progenitor cells responded to excessive mechanical stress to abnormally detach from the apical surface, which lead to disruption of cortical histogenesis (Fig. 3) (Okamoto et al., Nat. Neurosci. 2013: http://www.nature.com/neuro/journal/v16/n11/full/nn.3525.html). Following this study, we are now investigating mechanism underlying mechanosensation by progenitor cells.


v) Cell-cell interaction in heterogeneously crowded neuroepithelium and its contribution to cell-fate choice (Kawaue, Miyata)
Neuroepithelium is dynamically composed of cells differing in cell cycle phase and differentiation status. We investigate how a daughter cell’s fate is influenced by its interaction with neighboring cells. Three-dimensional imaging using transgenic mouse lines that we recently made (Kawaue et al., Dev. Growth Differ. 2014: http://onlinelibrary.wiley.com/doi/10.1111/dgd.12131/abstract;jsessionid=8FEFD53CB40ED938E616C30E8939A82D.f02t03) will be carried out.

vi) Collective migration of neurons and tissue mechanics (Saito, Miyata).
Mechanical factors should be considered not only for progenitor cells but also for neurons. We are asking this issue using live imaging and mechanical evaluations.

vii) Migration mechanism and role of microglia in embryonic cerebral walls (Hattori, Naito, Miyata)
Although it is known that microglia exist in the developing cerebral cortex from early embryonic days, how they behave there and what factors are involved are unclear. We are investigating this issue by combining neurodevelopmental and immunological approaches.

viii) Intravital live observation of developing brain (Hattori, Saito, Miyata)
Although slice culture methods are powerful to live observe cellular behaviors that construct brains, isolation from the normal (vascularized and complete three-dimensional) environment limits our investigation. Thus, we are trying to perform in utero live observation of developing brain cells.

2. Study to elucidate molecular mechanisms in regulating differential behaviors of neural progenitor cells (Kawaguchi group).


i) Temporal characteristics of the neural progenitor cells (Saito, Kawaguchi)
Cell cycle progression is not necessary for transitions in temporal gene expression and the laminar fate of neural progenitor cells (Okamoto et al., 2016, Fig5). We are investigating “timer” mechanism by which neural progenitor cells know the right developmental time.


ii) Detachment from the apical surface (Kawaue, Kawaguchi)
Some daughter cells generated by the division of neural progenitor cells detach their apical process from the apical surface and migrate out from the ventricular zone (Fig6). We are studying the molecular mechanisms regulating this detachment.
