Novel approaches in regenerative medicine and tissue engineering are highly promoted by human induced pluripotent stem cells. Typical workflows include the expansion, differentiation and/or cryopreservation of these cells. Often, the differentiation, cytotoxicity tests or disease modelling rely on multicellular aggregates. Here, we present the novel bag-based system “Labbag®” to address workflows required for these applications. As a unique feature, the Labbag® provides a chemical spot pattern to allow the formation of several hundreds of hanging droplets within a few seconds with standard laboratory equipment. In this study, we describe the general concept of the Labbag® and show aggregate formation of stem cells as first stem cell workflow successfully transferred.
