  • Method for culturing stem cells
    Patent number: 9163214
    Abstract: In the field of biological technology, a stem cell culture method is provided. The method includes preparing an amniotic epithelial cell feeder layer that is not treated to lose the division ability; and seeding the stem cells onto the amniotic epithelial cell feeder layer, and culturing in a culture medium. The stem cell culture method according to the present invention does not require the treatment of the feeder layer cells to lose the division ability, and is thus simple and safe, thereby effectively solving the problem of contamination caused by animal-derived ingredients in culture of human stem cells at present, greatly reducing the culture cost of the stem cells, and providing a safe, effective, and inexpensive stem cell culture method for the industrialization of the stem cells in the future.
