The IPS-Spheres are 100 µm polystyrene microcarrier beads coated with laminin protein. These beads are optimized for suspension culture of human iPS cells in a spheroid cluster format that resembles embryoid bodies. Cultivation in suspension format has several advantages including ease of handling, passaging, and direct differentiation without the need for an additional step of generating EB (since the cells are already in an EB format). Cells can be cultured in aerated-flasks or a 6 well plate format with or without agitation. The IPS-Spheres are a product of Brilliant Research Pte., Ltd. (Singapore) and available globally from REPROCELL.
