Abstract

Official abstract text for this publication.

Provided are multi-phase systems that may be used to prepare a three-dimension aggregate of cells referred to as a cellular spheroid. The multi-phase system includes a droplet of an aqueous polymer phase within an immersion aqueous polymer phase. The droplet of the droplet aqueous polymer phase contains a three-dimensional aggregate of cells (cellular spheroid). Types of cells that may be used in the multi-phases system include stem cells and cancer cells. The cellular spheroids with the multi-phase system may be used to monitor cell growth in three-dimensional systems, or screen drugs in a three-dimension aggregate of cells.

First claim

Opening claim text (preview).

What is claimed is: 1. An aqueous two-phase system for cell aggregates comprising: an immersion aqueous polymer phase; and within the immersion aqueous polymer phase, a droplet of a droplet aqueous polymer phase containing a three-dimensional aggregate of cells. 2. The aqueous two-phase system of claim 1 , where the three-dimensional aggregate of cells is a cellular spheroid. 3. The aqueous two-phase system of claim 2 , where the cellu…
