Stem cell screening inside the incubator

With conventional cell monitoring procedures, a culture vessel has to be taken out of the incubator for microscope observation, where cells are subjected to stressful environmental changes and vibration. Researchers then have to spend additional time repositioning the vessel to find the same observation points. Nikon's BioStation CT eliminates these problems by providing a stable environment so that the cultures don't suffer while they are being imaged and allowing for a complete trace of the same live cells, including stem cells.

Advanced basic functions

Automatic image capture

The autofocus mechanism allows the capture of in-focus images. Z-stack imaging in phase contrast observation, multi-sample imaging and multi-point imaging are possible with multiple magnifications. User-configured imaging conditions that can be saved in BioStation CT support the repeatability of observations.

Automatic vessel transportation

BioStation CT incorporates a transport unit that provides stable vessel transportation within the heated and humidified incubation area. The high-precision motorized stage in the observation unit allows for automated imaging of the entire area of a well in all culturing formats.

The transport unit carefully conveys the vessels from the storage rack to the observation stage in accordance with configured schedules.

Remote access

Configuring the imaging settings, scheduling a time-lapse experiment, and viewing the cell images are possible via a network. The captured data can be automatically downloaded to the user's local computer. This enables users to monitor the cell status away from the laboratory. When a culture environment (temperature, humidity, CO2 concentration) control error occurs, BioStation CT can notify the users of the error by e-mails.

Various functions

Full-well scan imaging and highly magnified image stitching

High-resolution full-well scans are reconstructed by stitching captured adjacent images. This enables clear detection of an iPS colony, which is difficult to detect because of its low induction efficiency, no matter where it forms in the vessel. The specified position of the vessel can be highly magnified with high resolution. BioStation CT also offers cell registration to allow for repeated visits to the same location. These time-lapse sequences can be created even when a vessel is removed from the BioStation CT for medium exchange.
[Note] Depending on the vessel used, the BioStation CT may not be able to focus on some areas.

Micro observation

Phase contrast and fluorescence images can be captured with the high-sensitivity cooled CMOS camera. These images can be magnified in 2x, 4x, 10x, 20x and 40x. Up to 40 phase contrast images can be captured along the Z axis with the Z-stack function.

Macro observation

Brightfield image of the whole vessel provides users outside the BioStation CT with information such as handwritten information on the vessel, medium color and whether mold is growing or not. In addition, alkaline phosphatase stained cell counting is possible with the optional image analysis software CL-Quant.

Stable culture environment maintenance

Precise temperature control

The inside temperature is directly controlled by panel heaters embedded in the incubator's six sides. This allows highly precise temperature maintenance.

Humidity control with air-flow type active aerosol spray humidifier

Distilled water is automatically sprayed inside the incubator to keep the optimum humidity. Water can be supplied to the tank without opening the incubator door. This air-flow type humidifier reduces contamination risks compared to the water bath type.

Environment data recording

The culture environment is constantly monitored and recorded. The environment data can be accessed at anytime.

Smooth vessel transportation

The waver of liquid surface during the transportation is less than 2 mm. The drift and stress of cells are reduced.

Reduced contamination risk

The incubator interior can be sterilized using hydrogen peroxide gas. (This is optional, and a 200 V power source is necessary.)

Easy operations

1. Vessel installation

Culture vessel installation into the storage rack

Vessels are placed in the incubator through a small door on the front glass panel, minimizing the effect on the environment within the incubator.

2. Imaging parameter setting

Easy touchscreen operation

Time-lapse imaging configurations such as magnification, imaging point, fluorescence channel and stage motion speed can be set.

3. Scheduling

Time-lapse imaging schedule

The imaging interval and total period can be set. The shortest time-lapse imaging interval is one minute.

4. Captured image view

Culture history data management

The time-course change of a specimen can be observed easily in sequentially displayed captured images.

5. Medium exchange

High-precision repeatability

Accurate tracing of same cells, even after medium exchange, is possible using a dedicated tray holder, as BioStation CT records culture history, such as medium exchange and subculture, as well as X-Y positions for each vessel.

6. Data report

Reliable data management and documentation support

Obtained data is duplicated and protected using uninterruptible power supply. Observation information such as temperature, humidity and imaging date can be written and displayed on the captured image to simplify presentation document preparation.
