- New microcarrier, or particle utilized in bioreactor-based cell manufacturing, provides considerably greater harvest of cells grown with over 90% harvest fee in comparison with 50-60% fee seen in present requirements
- Homogenous microcarrier dimensions facilitate uniform environmental situations for controlling constant cell numbers per microcarrier
- Facilitates growth of mesenchymal stromal cells used to deal with varied illnesses comparable to coronary heart assaults, bone defects and immune system rejection of cell therapies
Singapore, 29 October 2020 – Researchers from Singapore-MIT Alliance for Analysis and Know-how (SMART), MIT’s analysis enterprise in Singapore, have developed a novel microcarrier for large-scale cell manufacturing and growth that provides greater yield and cost-effectiveness in comparison with conventional strategies, and reduces steps required within the cell retrieval course of. Microcarriers are particles utilized in bioreactor-based cell manufacturing of anchorage-dependent cells.
SMART’s newly developed dissolvable gelatin-based microcarrier has confirmed helpful for growth of mesenchymal stromal cells (MSCs), a cell kind of nice present curiosity as they are often remoted from grownup tissues and additional expanded to deal with varied illnesses comparable to bone and cartilage defects and the physique’s rejection of overseas bone-marrow and cells (referred to as graft vs. host illness). This dissolvability of the microcarriers additionally eliminates an extra separation step to retrieve the cells from the microcarriers. This reduces the complexity of cell manufacturing and growing the convenience with which the therapeutic cells might be harvested to make the product for sufferers.
SMART’s Important Analytics for Manufacturing Personalised-Drugs (CAMP) Interdisciplinary Analysis Group (IRG) found that gelatin microcarriers, which totally dissolves in enzymatic remedy, might be helpful within the cell restoration step – one of many present bottlenecks confronted in 3D microcarrier tradition. The novel gelatin microcarrier confirmed greater yield and lowered cell loss on the cell harvesting step in comparison with business microcarriers, with comparable cell attachment effectivity and proliferation fee.
Their discovery is defined in a paper titled “Dissolvable gelatin-based microcarriers generated by way of droplet microfluidics for growth and tradition of mesenchymal stromal cells” revealed in Biotechnology Journal and co-authored by researchers from SMART CAMP, Massachusetts Institute of Know-how (MIT), Nationwide College of Singapore (NUS) and Metropolis College of Hong Kong (CityU).
“Our examine achieved over 90% harvest fee of cells grown on the gelatin microcarriers, which is considerably greater than the 50-60% harvest fee seen in present requirements,” mentioned Dr. Ee Xien Ng, lead writer of the paper and CAMP alumnus. “Utilizing gelatin microcarriers additionally achieved tight management over microcarrier dimensions (for instance, microcarrier diameter and stiffness) that facilitate uniform environmental situations for controlling constant cell numbers per microcarrier.”
The analysis additionally confirmed that MSCs cultured by gelatin microcarriers retain vital high quality attributes of retrieved cells, comparable to a better diploma of trilineage multipotency with extra balanced differentiation efficiency in comparison with business microcarriers. Most business microcarriers confirmed related traits in adipogenic differentiation effectivity, whereas dropping some levels of chondrogenic and osteogenic differentiation functionality.
“Improvements in microcarriers will support within the scalability of sure cell sorts comparable to mesenchymal stromal cells for cell-based remedy, together with for regenerative medication functions,” says Professor Krystyn J. Van Vliet, co-author of the paper in addition to Lead Principal Investigator at CAMP and Professor of Supplies Science and Engineering and Organic Engineering at MIT. “Creating a microcarrier platform for MSC tradition has been a key half for SMART CAMP’s understanding and managing the vital high quality attributes of those cell remedy merchandise. We hope our findings assist result in higher, extra environment friendly and scalable cell therapies with predictable therapeutic outcomes for a number of affected person wants, and excessive harvesting effectivity of these potent cells.”
Whereas the examine targeted on whether or not gelatin microcarriers are appropriate for MSC tradition and growth, the workforce’s analysis might probably be prolonged for different varieties of anchorage-dependent cells.
The analysis is carried out by SMART and supported by the Nationwide Analysis Basis (NRF) Singapore underneath its Campus for Analysis Excellence And Technological Enterprise (CREATE) programme.

About Important Analytics for Manufacturing Personalised-Drugs (CAMP IRG)
CAMP is a SMART interdisciplinary analysis group launched in June 2019. It focuses on higher methods to provide dwelling cells as medication, or mobile therapies, to supply extra sufferers entry to promising and accredited therapies. The investigators at CAMP handle two key bottlenecks going through the manufacturing of a variety of potential cell therapies: vital high quality attributes (CQA) and course of analytic applied sciences (PAT). Leveraging deep collaborations inside Singapore and MIT in america, CAMP invents and demonstrates CQA/PAT capabilities from stem to immune cells. Its work addresses illnesses starting from most cancers to tissue degeneration, focusing on adherent and suspended cells, with and with out genetic engineering.
CAMP is the R&D core of a complete nationwide effort on cell remedy manufacturing in Singapore.
