  • Design and operation of bioreactor systems for the expansion of pluripotent stem cell-derived neural stem cells

    Neurodegenerative disorders, such as Parkinson's disease, Huntington's disease, and multiple sclerosis, affect millions of people worldwide, with devastating impact on the patients and families. A reliable method to obtain cells for replacement therapy, using ex-vivo culture techniques, would be of great value for the treatment of these conditions. This project focuses on the development of bioreactor culture systems for the large-scale expansion of neural stem cells, starting with a model line of mouse embryonic stem cell- derived neural stem cells under adherent culture conditions. Adherent conditions are an alternative to conventional culture of NS cells as aggregates and may circumvent problems associated with this system. Small scale stirred bioreactors were successfully used for mNS cell expansion, with microcarriers to support cell adhesion and proliferation, with retention of neural stem/progenitor cell markers. The system was optimized by determining the best values for parameters like stirring speed, microcarrier concentration or feeding regimen. The system here described may open a new door for applications requiring high numbers of mouse neural cells, providing an efficient way for their generation. Furthermore, the know-how obtained with this work may be applied for the development of an equivalent system for human cells, which may find clinical applications.

  • Comparative proteomic analysis of neural stem cells between differentiating and undifferentiating to dopaminergic neuron

    The neural stem cells were induced by low-level dopamine (DA). We allowed cells 72 h of differentiation before protein extraction. The global proteins of neural stem cells and dopaminergic neurons were extracted. In this study, the protein from cell lysat was rudiment separated by SDS-PAGE, and the gel strip was cut into several portions. The protein in each portion is digested by trypsin, and then the peptides mixtures were analyzed by mass spectrometry (LC-MS/MS). 839 proteins in the neural stem cells and 718 proteins in the dopaminergic neuron were identified. The nestin protein was found in the NSCs and the Sodium-dependent dopamine transporter (DA transporter)(DAT) was found in the dopaminergic neuron which was induced by low level DA. The cytoskeletal proteins rearranged after the NSCs differentiated and regulating proteins changed a lot.

  • Multi-Thread, Increment-Bandwidth and Weighted Mean-Shift Algorithm for Neural Stem Cells Tracking

    For studying their activities in time lapse image sequences, as some limitations of traditional mean-shift algorithm (MSA) applied in large population cells' tracking exist, an improved MSA with increment bandwidth and adjusted weight is presented for the neural stem cells tracking. Meanwhile, as the limitation of serial computation of MSA, multithreading technique is applied to save tracking time. The presented algorithm has been tested in three image sequences. Tracking result from comparison between improved and traditional MSA shows that the former has increased the accuracy rate and saved time, especially in large populationpsilas cells tracking.

  • Differentiation of neural stem cells regulated by three-dimensional tissue shape

    This paper describes the effect of three-dimensional (3D) tissue shape on differentiation ratio of neurons. We cultured mouse neural stem cells (mNSCs) in the closed agarose microchamber sealed with an agarose sheet. We succeeded in fabricating mNSC tissues of various 3D shapes in the closed agarose microchamber and induced differentiation of the lane-shaped mNSC tissues to neurons and glial cells. We confirmed that tissues of thin width and thickness have higher differentiation ratio of neurons than that of spherical-shaped tissue, by changing the width and thickness of the lane shaped tissues.

  • Reconstruction of vascular niche of neural stem cells using perfusable microfluidic device

    In brain, vascular niche is well known to function for regulation of proliferation and cell fate decision of neural stem cells (NSCs). The NSC niche is composed of vascular endothelial cells (VECs), and shear stress is known as a key factor on activity of the VECs. To reconstruct the NSC niche, perfusable coculture system is needed. Here we developed perfusable microfluidic device for coculture of NSCs and VECs under shear stress mimicking physiological flow. We found that NSCs and VECs were activated under the shear stress, and highly expressed NSC-associated genes and shear stress responsive genes, respectively. The finding indicates that the culture system using the microfluidic device can reproduce NSC niche for research on development, homeostasis and regeneration of central nervous system (CNS).

  • Automatic Segmenting and Classifying the Neural Stem Cells in Adherent Culturing Condition

    The neural stem cells (NSCs) have a wide range of perspectives in clinical applications for neurology disorders due to their multi-potent potentials of differentiation. Automatic segment and classify the NSCs can be useful tools for biologist to monitor the progress of differentiation. In this paper, a hybrid image segmentation framework based on self-organizing map and watershed algorithm was applied to segment the NSCs in adherent culturing conditions. The cells shapes were analyzed using Fourier descriptors and classified using a feed-forward neural network. The results indicated that different shapes of NSCs in adherent culturing condition can be successfully segmented and classified based on these methods.

  • Donation of neural stem cells? Post mortal viability of spinal cord neuronal cells

    Transplantation of cells into central nervous system (CNS) shows a potential for treatment of post-traumatic and neurodegenerative diseases. Cadaver- derived neural cells can help reducing deficit of allogeneic material ready for transplantation. In this study we analyze post-mortal survival of spinal cord neural cells. Maximal time when alive neuronal cells can be recovered form spinal cord of the animals was determined as 56hr for human-size animal and 18hr for rat. Cells with surface expression of ganglioside GD2 and antigen CD24 constituted up to one percent of all recovered alive cells in earlier samples with time dependent decline in percentage. GD2-positive cells from rat spinal cord demonstrated spontaneous and induced electrical activity, which reduces with time post mortem.

  • Magneto-Optical Labeling of Fetal Neural Stem Cells for in vivo MRI Tracking

    Neural stem cell therapy for neurological pathologies, such as Alzheimer's and Parkinson's disease, may delay the onset of symptoms, replace damaged neurons and/or support the survival of endogenous cells. Magnetic resonance imaging (MRI) can be used to track magnetically labeled cells in vivo to observe migration. Prior to transplantation, labeled cells must be characterized to show that they retain their intrinsic properties, such as cell proliferation into neurospheres in a supplemented environment. In vivo images must also be correlated to sensitive, histological markers. In this study, we show that fetus-derived neural stem cells can be co-labeled with superparamagnetic iron oxide and PKH26, a fluorescent dye. Labeled cells retain the ability to proliferate into neurospheres in culture, but labeling prevents neurospheres from merging in a non-adherent culture environment. After labeled NSCs were transplantation into the rat brain, their location and subsequent migration along the corpus callosum was detected using MRI. This study demonstrates an imaging paradigm with which to develop an in vivo assay for quantitatively evaluating fetal neural stem cell migration

  • Online 3-D Tracking of Suspension Living Cells Imaged with Phase-Contrast Microscopy

    Neural stem cells/neural progenitors (NSCs/NPs) are cells that give rise to the main cell types of the nervous system: oligodendrocytes, neurons, and astrocytes. Studying NSCs/NPs with time-lapse microscopy is critical to the understanding of the biology of these cells. However, NSCs/NPs are very sensitive to phototoxic damage, and therefore, fluorescent dyes cannot be used to follow these cells. Also, since in most of NSC/NP-related experiments, a large number of cells neesd to be monitored. Consequently, the acquisition of a huge amount of images is required. An additional difficulty is related to our original suspension living, tracking objective, behavior much closer to the natural, in vivo, way of development of the cells. Indeed, unlike adherent cells, suspension cells float freely in a liquid solution, thus, making their dynamics very different from that of adherent cells. As a result, existing visual tracking algorithms that have primarily been developed to track adherent cells are no longer adequate to tackle living cells in suspension. This paper presents a novel automated 3-D visual tracking of suspension living cells for time-lapse image acquisition using phase-contrast microscopy. This new tracking method can potentially strongly impact on current 3-D video microscopy methods, paving the way for innovative analysis of NSCs/NPs and as a result, on the study of neurodegenerative diseases.

  • Accurate Extraction of Contour Information from the Cleavage of Neural Stem Cells

    Accurate extraction of contour information from neural stem cells is important, as the shapes of neural stem cells may contain significant features for studying their activities in time lapse image sequences especially during their cleavage. In this paper, an algorithm is presented for this purpose. Fuzzy threshold method based on Zadeh's maximum entropy is adopted for cell segmentation. The best parameters of maximum fuzzy entropy are computed using genetic algorithm. The acquired contours are then smoothed in their one- dimensional Centroid-Contour Distance (CCD) diagrams. Compared with the results derived from traditional segmentation methods, the contours extracted using our method are much closer to the real cells, even for tiny objects size down to 30 pixels in images.
