EXPANSION OF STEM CELLS IN SUSPENSION IN A BIOREACTOR
20230059873 · 2023-02-23 · ·

The present invention relates to a method of expanding pluripotent stem cells (PSC) in suspension culture in a bioreactor, the method comprising (i) adding an inhibitor of ROCK (ROCKi) to pluripotent stem cells being cultivated in suspension in the bioreactor; (ii) adding a cell dissociation agent, thereby dissociating aggregates of the pluripotent stem cells; (iii) diluting the cell dissociation agent added in step (ii) by adding an excess volume of culture medium sufficient to decrease the concentration of the cell dissociation agent to a concentration at which cell aggregates can form again; and (iv) culturing of the mixture obtained in step (iii) under suitable conditions that allow the expansion of the PSCs.

20170304369 · 2017-10-26 ·

The present disclosure provides methods and kits for the differentiation of stem cells into relevant liver cell lineages, as well as methods of using the relevant liver cell lineages in screening for a cellular response, a phenotype and in the treatment of a condition. In one embodiment, stem cells are first differentiated into cells of the definitive endoderm lineage, which are differentiated into posterior foregut (PFG) lineage cells by one or more of retinoic acid activators and/or one or more inhibitors of transforming growth factor-β (TGFβ). An additional embodiment provides a method for the differentiation of posterior foregut lineage cells into liver bud progenitors (LB) by one or more activators of TGFβ signalling, and/or one or more modulators of Wnt signalling, and/or one or more activators of cyclic AMP/PKA signaling; and a further embodiment provides a method for the differentiation of liver bud progenitors into hepatic progenitors by one or more inhibitors of TGFβ signalling and/or fibroblast growth factor (FGF) inhibitors and/or one or more Notch inhibitors. Another embodiment discloses the differentiation of hepatic progenitors into hepatocyte-like cells or perivenous hepatocyte-like cells by one or more of Notch inhibitors and/or activators of glucocorticoid signalling and/or one or more activators of insulin signalling and/or one or more of ascorbic acid signalling activators and/or additional factors. Methods and kits for maintaining LB in self renewal state, hepatocyte-like cells in perivenous or periportal state, as well as surface markers for LB and mid/hindgut (MHG) cells are also disclosed.
