Culture of Normal Human Dermal Fibroblast Cells in a Functionally Closed Automated Cell Expansion System

The Quantum Cell Expansion System is a functionally closed and automated hollow-fiber bioreactor system that is designed to expand both adherent and suspension cells in a reproducible manner. The hollow-fiber membrane requires a coating agent to help facilitate cellular adherence when culturing an adherent cell type such as MSCs. Pooled human cryoprecipitate (CPPT, Bonfils Blood Center) was examined as an alternative to FN because it is a rich source of extracellular matrix components, including fibrinogen (Freedman, 2010), and also because…

Regenerative Medicine

    The year 2011 may be seen as one in which regenerative medicine entered its adolescence. Public attention — from investors to desperate patients — finally turned toward this nascent industry with something other than skepticism or unrealistic expectations. The FDA’s approval of Dendreon’s Provenge cellular immunotherapy switched on the spotlight, and cell therapy companies suddenly faced a barrage of questions about cost, manufacturing issues, product development, and patient access. US Policy: In May 2011, US representatives Brian Bilbray…

Cell Therapies Roundtable: Building the Pillars to Success

In order to deliver cell-based therapies on a commercial scale, cell therapy companies and suppliers must form partnerships in order to overcome existing manufacturing, regulatory, and analytical challenges. Four leading cell therapy experts discuss what is and what has to be done in order to accomplish this objective.

Implementing Custom Single-Use Solutions for Cell Therapy Production

Cellular therapy continues to expand and gain momentum, as evidenced by the growing number of companies and clinical trials in the field each year. Early potential therapies were developed solely by investigators without communication or input from manufacturing experts. That communication gap led to numerous setbacks as potential products were developed without roadmaps for feasible manufacturing scale-up (or scale-out). Contributions from members of the cell therapy community over the past few years have significantly improved the situation in the form…

Scaling Up Stem Cells

    Cell-based products are becoming increasingly important as potential biotherapies. Cell therapy is predicted to have a huge impact on the healthcare sector over the coming decades. Stem cells, in particular, are investigated as potential treatments for a diverse range of applications (such as heart disease and metabolic and inflammatory disorders) in which they might be used to restore lost biological functions. The cell therapy industry is starting to mature. Several emerging companies are now supporting late-stage clinical trials,…

Standards Can Help Bring Cell Therapy Products to Market

Companies trying to market cell therapy products face a number of challenges in communicating highly technical knowledge, understanding the nature and complexity of their products, and trying to understand the global regulatory environment within which they must operate. The role standards development organizations (SDOs) play is key to overcoming some of those challenges through a standardization process. The British Standards Institution (BSI) sits at the forefront, developing a number of documents that will increase the chances of cell therapies for…
