COMBINED SCALABLE IN VITRO DIFFERENTIATION SYSTEM FOR HUMAN BLASTOCYST-DERIVED STEM (HBS) CELLS OR CELLS DERIVED FROM HBS CELLS FOR DIRECT ASSAY APPLICATION IN MULTIWELL PLATES
First Claim
1. A combined differentiation and assay method for hBS cells or cells derived from hBS cells wherein said cells are differentiated in the same format as they are further being subject to analysis in, the method comprising the steps:
- (i) dissociation of the cells into single cells, clusters or a mixture thereof;
(ii) seeding of the dissociated cells into one or more wells of one or more multi-well format plates;
(iii) application of a centrifugal force to the seeded cells for enhanced coalescence;
(iv) incubation to differentiate the cells and without re-plating in steps (ii)-(iv) and assaying the cells without replating.

Abstract
A combined scalable in vitro differentiation and assay system based on human blastocyst-derived stem (hBS) cells or cells derived from hBS cells is provided. This system makes it possible to merge both the differentiation and the assay parts of the system into one. The advantage of the combined assay system is that the hBS cells or the cells derived from hBS cells in the differentiation system are directly applicable for assays, in a large variety of assay units, such as different multiwell plates. The system offers a major improvement compared to the prior art, since the cells are differentiated in the same format as when further being subject to analysis. The starting cell material can be homogenously distributed across a variety of different plates, for use and can be cultured when attached, when semi-attached or when in suspension.
