Expansion and Characterization of Mesenchymal Stem Cells on Pall SoloHill® Microcarriers

by , and

Mesenchymal stem cells (MSCs) are self-renewing cells that differentiate into several terminally differentiated cell types. These cells have been isolated from multiple sources such as bone marrow, adipose tissue, peripheral blood, and other adult tissues(1–6). The interest in these cells is that they hold the potential to cure disease and are being pursued in clinical trials. Three emerging fields of interest for stem cells are cell therapy, regenerative medicine and screening of candidate drugs. In many cases, poor correlation between…

Strategies for Microcarrier Culture Optimization

by and

The process of delivering an allogeneic stem-cell therapy to patients requires isolation and expansion of rare tissue-specific stem cells, which are subsequently delivered to individual patients for treatment. One type of cell used for such therapies is commonly known as human mesenchymal stem cells (hMSCs). They have been isolated from a number of tissues: e.g., bone marrow, heart, brain, placenta, and umbilical cord. And they have been shown to be immune-privileged in that hMSCs elicit no graft-versus-host (GvH) response such…

SoloHill Microcarriers in a 25-L PadReactorâ„¢ Single-Use Bioreactor

by , and

        The purpose of this study was to demonstrate compatibility and performance of SoloHill’s Collagen-coated microcarriers in ATMI Lifesciences’ Integrityâ„¢ PadReactorâ„¢ system. The solid polystyrene core of the collagen microcarriers prevents absorption of serum or cell products into the core of the microcarrier, and the 1.03 specific gravity and 125- to 212-μm diameter allows them to be maintained in suspension with gentle low stirring speed. These solid microcarriers provide an excellent substrate for cell growth. They can…
