  • Patent number: 8828720
    Abstract: We disclose a particle comprising a matrix coated thereon and having a positive charge, the particle being of a size to allow aggregation of primate or human stem cells attached thereto. The particle may comprise a substantially elongate, cylindrical or rod shaped particle having a longest dimension of between 50 ?m and 400 ?m, such as about 200 ?m. It may have a cross sectional dimension of between 20 ?m and 30 ?m. The particle may comprise a substantially compact or spherical shaped particle having a size of between about 20 ?m and about 120 ?m, for example about 65 ?m. We also disclose a method of propagating primate or human stem cells, the method comprising: providing first and second primate or human stem cells attached to first and second respective particles, allowing the first primate or human stem cell to contact the second primate or human stem cell to form an aggregate of cells and culturing the aggregate to propagate the primate or human stem cells for at least one passage.
