General description

The development of the vertebrate nervous system entails the generation and differentiation of neurons, establishment of signaling circuits, and the formation of numerous synapses. In particular, the formation of axons and dendrites during differentiation has been an area of intense interest. Although tremendous progress has been made in this area, neuronal outgrowth studies have been hampered by the absence of a solid, easy to use, neurite culturing platform which physically orients the cells during investigation. Traditional outgrowth experiments, conducted either by culturing neural stem cells, primary neurons, or tissue slices, typically result in random, overlapping neurite extensions. The ability to address questions surrounding the specific roles of axons, dendrites and somas in neuron differentiation and growth requires a faster, more specialized method that allows scientists to spatially isolate and study individual neurites and their function.
To this end, Millipore now offers its most advanced tool for the isolation, visualization, and characterization of neurite outgrowth, the AXon Investigation System (AXIS). AXIS is a unique, easy to use, slide-mounted microfluidic platform that allows culture, regulation, and directional differentiation of neuronal cells via a system of growth chambers and interconnected channels. AXIS devices physically isolate developing neurites from each other and their respective neural cell bodies. In addition, the use of hydrostatic pressure during analysis provides researchers with an opportunity for targeted exposure of neuronal parts to growth factors, drug compounds, or other reagents of biological interest. This ability to selectively control exposure of neuronal outgrowth makes AXIS a powerful platform for any researcher interested in understanding axons, dendrites, somas, and their roles in synaptic formation, neural cell development, differentiation, regeneration, degeneration, and trauma.
These Plasma Bonded AXIS products are AXIS devices that have been permanently sealed to glass bottomed tissue culture dishes using plasma gas exposure. This format essentially eliminates issues with leakage or cell penetration under the device and should facilitate researchers in their live or fixed cell confocal imaging. These plasma bonded devices are currently being offered in three different formats to provide test flexibility during investigation.

AX50005PB consists of 5 units of AX500, an axon isolation device consisting of 6 wells, 3 channels and two separate sets of microgrooves that are 500 µm in length. The middle channel is 500 µm wide and lies between the two sets of microgrooves. Each microgroove is approximately 5µm in height by 10µm in width and are designed to allow neurite passage to traverse through while preventing cell bodies from flowing across the device. There are roughly 120 microgrooves in each AX500 device.

The AXIS Axon Isolation Devices have been shown to effectively isolate cell bodies from differentiating neurites for a variety of cell types (Taylor et al., 2005; Park et al., 2006; Liu et al., 2008; Yang, et al., 2009; Taylor et al., 2009) and will likely work with most neuronal cell type that can be successfully grown in tissue culture. Because the AXIS devices are made from an inert and non-toxic polymer, cultures grown within AXIS devices can be maintained for weeks at a time. (Chun et al., 1992; Shibayama et al., 1991). In addition, because the polymer used to fabricate the axon isolation devices is optically clear, cells cultured within the device can be imaged with high resolution microscopy, including live cell imaging, confocal, and differential interference microscopy (Taylor et al., 2005; Park et al., 2006; Liu et al., 2008; Yang, et al., 2009; Taylor et al., 2009).

The microfluidic design of the AXIS devices is highly conducive to generation of hydrostatic pressure, which can be selectively used to isolate a solution, as well as chemical targets of interest, on a designated side of the device (Park et al., 2006). In addition, immunocytochemistry (IHC) can also be performed within an AXIS Axon Isolation device and a protocol to do so is provided in the manual.
