Definitions
- the present invention relates to a microfluidic suspension culture device for culturing cell aggregates.
- Tissue-specific organoid culture technology is a cutting-edge field that is currently receiving the most spotlight in stem cell research, and has unlimited potential in regenerative medicine and new drug research, such as intractable disease models, patient-specific drug screening platforms, and in vitro models for new drug development. can be expanded.
- the technology of culturing cells using microfluidic devices is a technology that provides a microenvironment suitable for cells and precisely controls the culture conditions of cells that react sensitively to the surrounding environment. are receiving
- a culture dish was mounted on an orbital shaker or a bioreactor such as a spinner flask was used, but each organoid
- the flow of the fluid provided to the organoids is not uniform, which can cause extreme batch-to-batch variation, which is pointed out as the biggest problem in organoid research.
- the conventional suspension culture technique is performed by placing a microliter volume (20-50 ⁇ l) of cell culture solution on a glass or Petri dish. After that, invert the glass or Petri dish. The droplet is prevented from falling due to surface tension, the cells hanging in the culture medium are settled by gravity, and the cells settled in the culture medium interact with adjacent cells to form a bond, forming a three-dimensional spheroid or three-dimensional micro-organism. to form
- the greatest difficulty in this technique is the exchange of the culture medium from the droplet.
- the present inventors developed a microfluidic suspension culture device capable of generating a flow of fluid without a separate facility using a stirring device commonly used in laboratories, and confirmed that the viability, differentiation ability and functionality of organoids can be improved did.
- the present invention provides a culture chamber comprising one or more wells; one or more reservoirs for storing the culture solution; and a microchannel connecting the culture chamber and the reservoir.
- the present invention relates to the device; stirrer; And it aims to provide a cell aggregate culture system comprising a; and a culture medium shared through the microchannel.
- An object of the present invention is to provide a method for culturing a cell aggregate using the culture system.
- One aspect of the present invention is a culture chamber comprising one or more wells; one or more reservoirs for storing the culture solution; and a microchannel connecting the culture chamber and the reservoir.
- the culture chamber may further include a microchannel connecting a plurality of wells.
- the diameter of the well may be 1.5 to 4 mm, and the interval between the wells connected to the microchannel may be 1.5 to 5 mm.
- the reservoir may be located at both ends of the device.
- the cell aggregate is any one of mesenchymal stem cells, neural stem cells, vascular endothelial cells, induced pluripotent stem cells, embryonic stem cells, tissue stem cells, fetal stem cells, cancer stem cells and cardiac cells. It may be a derived spheroid or an organoid.
- the cell aggregate is brain, optic cup, kidney, liver, pancreas, neural tube, stomach, large intestine, prostate, breast, heart, salivary gland, endometrium, It may be derived from one of the group consisting of mammary gland, thyroid, tongue, small intestine, esophagus, spinal cord, skin, bile duct, lung, blood vessel, muscle, adrenal cortex and thyroid organoids.
- Another aspect of the present invention is the device; stirrer; and a culture medium shared through a microchannel; provides a cell aggregate culture system comprising.
- the device may swing motion by the stirrer.
- Another aspect of the present invention provides a method of culturing a cell aggregate using the culture system.
- the cell aggregate culture device of the present invention the cell aggregate culture system including the same, and the method for culturing the cell aggregate using the same have the effect of more enhanced stem cell activity and high differentiation compared to the conventional cell aggregate culture technology.
- the cell aggregate culture device can be reused repeatedly and can be utilized as a platform according to various uses by changing the size and number of wells.
- the cell aggregate culture system utilizes a stirrer so that the culture solution located in the well in the reservoir and the culture chamber continues to flow through the microchannel, so that the environment of the entire well is maintained so that the cell aggregate can be cultured uniformly and with high efficiency.
- the cell aggregate culture system can be utilized as a disease research and drug screening model through mass production of cell aggregates in which the disease phenotype is maintained, and also applied to transplantation treatment for disease treatment through mass production of therapeutic cell aggregates. It is possible.
