Tech Can Solve Stem Cell Sector’s Manufacturing Challenges, Genetic Engineering & Biotechnology
05-Jan-2021

Transplanted stem cells have been used as regenerative therapies for decades. But stem cells have wider therapeutic potential. Despite this potential, to date only one stem cell therapy—the ocular burns treatment Holoclar—has been approved by a major regulator. Manufacture is a major challenge that holds back the sector, according to Steve Oh, director of stem cell bioprocessing at Singapore’s Agency for Science, Technology and Research (A*STAR). To try and address the scalability issue Oh and colleagues developed a micro-carrier-based culturing process—in which the cells grow on the surface of beads in solution—to increase productivity. In addition, Oh notes, protein coatings such as laminin, vitronectin, and fibronectin can be added to the surfaces of the carriers to cater to different cell types. The approach also reduces manual steps, while reducing the overall costs of goods for biomanufacturing. The A*STAR technology was recently licensed to Singapore-based contract development and manufacturing organization (CDMO) SingCell, which is offering it as a service to cell therapy companies.

New Protocol Advances Toward Lab-Made Universal Red Blood Cells, The Scientist
17-Dec-2020

The COVID-19 pandemic has led to a steep drop in blood donations, leading blood centers in the US to raise the alarm about critical shortages, laying bare the fragility of the current blood supply. For years, scientists anticipating disruptions to the blood supply have been working on developing ways to produce blood in factories in order to provide an alternative source of the vital substance. In a study published on December 10 in Stem Cell Reports, Steve Oh, the director of the Stem Cell Bioprocessing group at the Agency for Science, Technology and Research (A*STAR) in Singapore, and his colleagues report a new method to generate large quantities of red blood cells (RBCs) from induced pluripotent stem cells (iPSCs), cells that have been reprogrammed from a differentiated state back to an embryonic-like state.

Study finds new way to starve cancer cells, The Straits Times
29-May-2019

Researchers from A*STAR and the National Cancer Centre Singapore (NCCS) discovered that cancer stem cells can use an amino acid called methionine as fuel and are especially dependent on it. The team found that starving lung cancer cells of methionine for 48 hours resulted in a “dramatic” 94 per cent reduction in tumour size compared with a control sample. Dr Tam Wai Leong, Group Leader for Precision Oncology at the Genome Institute of Singapore under A*STAR, said that it may be possible to prevent the cancer stem cells from using methionine by inhibiting an enzyme called MAT2A, and that it will be important for clinicians to select patients who are most likely to benefit from such a drug. The study also involved researchers from A*STAR’s Bioprocessing Technology Institute (BTI) and the team is working on developing a drug for clinical trials that inhibits MAT2A.

Unlocking New Antibiotics, Science & Technology Research News
3-Jan-2019

A*STAR researchers from ICES, BTI, MERL and MEL have unearthed a new antibiotic, auroramycin, from a silent biosynthetic gene cluster discovered in the S. roseosporus genome, and believe there are many more just waiting to be found. Dr Yee Hwee Lim from ICES said that this strain of bacteria is very well studied and it was interesting that, even after so many molecules have been discovered, they now have a new antibiotic simply because they had the tools to access it. The team used CRISPR-Cas9 to introduce a potent gene transcription activator - the kasO* promoter - into the bacterial genome to activate expression of an entire cryptic biosynthetic gene cluster. The gene cluster was found to encode auroramycin, an antibiotic with potent antibacterial activity against Gram-positive bacteria, including MRSA and vancomycin-resistant Enterococcus faecalis (VRE).

Uncapping a New Therapy, Science & Technology Research News
3-Jan-2019

Scientists from A*STAR have found that switching off the enzyme that adds protective caps to chromosome ends could help fight many types of cancer. The team from GIS, IMB, IMCB and BTI demonstrated the treatment's potential by using it to thwart tumour growth in mice. The team found that a master regulator of development, HOXC5, and the microRNA mir-615-3p, which is nested inside the HOXC5 gene, act together to suppress telomerase through these distant switches. Further study showed that the switches are present in many long-lived mammals, including humans and chimpanzees, but not in short-lived mammals, like mice and rats, as an extra barrier against the increased tumour risk that accompanies a longer lifespan.
