Stem Cells Might be Heading Soon to Dental Offices for Tooth Repair

GEN | August 12, 2019

An international team of scientists, including researchers from the Biotechnology Center of the TU Dresden BIOTEC, says it has found a new mechanism that could offer a potential solution to tooth repair. They discovered a new population of mesenchymal stromal cells in a continuously growing mouse incisor model. They have shown that these cells contribute to the formation of dentin, the hard tissue that covers the main body of a tooth. Importantly, the work showed that when these stem cells are activated, they send signals back to the mother cells of the tissue to control the number of cells produced, through a molecular gene called Dlk1. This study (“Transit amplifying cells coordinate mouse incisor mesenchymal stem cell activation”), which was published in Nature Communications, reportedly is the first to show that Dlk1 is vital for this process to work. In the same study, the researchers also demonstrated that Dlk1 can enhance stem cell activation and tissue regeneration in a wound healing model. This mechanism could provide an innovative solution for tooth repair, addressing problems such as tooth decay, crumbling, and trauma treatment. Further studies are needed to validate the results for clinical applications to determine the appropriate duration and dose of treatment.

Asahi Kasei Bioprocess America and GeminiBio Enter Strategic Partnership to Advance Application of Inline Buffer Formulation

businesswire | April 20, 2023

Asahi Kasei Bioprocess America, a subsidiary of diversified Japanese multinational company Asahi Kasei, and GeminiBio have entered into a strategic partnership to advance the application of inline buffer formulation (IBF) in the biopharmaceutical industry. Asahi Kasei Bioprocess, with decades of expertise in IBF and the developers of the award-winning MOTIV™ system, and GeminiBio, with industry leading bioprocess liquid manufacturing capabilities, are combining two high-efficiency solutions for buffer management to biopharmaceutical manufacturers in one package. This will result in fewer bottlenecks in manufacturing, streamlining the IBF process. The companies entered the agreement in March 2023 with the initial scope of the North American biopharmaceutical industry. Buffers are used extensively in the development and manufacturing process for all biopharmaceuticals. The manufacturing of buffers is time consuming and resource intensive, and often a significant bottleneck in the biopharmaceutical manufacturing process. The Asahi Kasei Bioprocess MOTIV IBF™ system is built specifically to debottleneck downstream processing to move product more efficiently through the manufacturing process. However, creating the buffer concentrates that are used with these systems has remained a challenge. Pairing MOTIV with GeminiBio’s pre-mixed concentrates provides biopharmaceutical manufacturers a total solution, resulting in a new level of efficiency and cost savings throughout the biopharmaceutical manufacturing process, yielding benefits throughout the entire value chain. “Our partnership with GeminiBio solidifies both companies’ commitment to improving the efficiency and efficacy of buffer formulation,” says Chris Rombach, Senior Vice President of Sales and Marketing at Asahi Kasei Bioprocess America. “The combination of Asahi Kasei Bioprocess America’s long-standing buffer formulation expertise and GeminiBio’s state-of-the-art buffer concentrate manufacturing capabilities will aid bioprocessors to reduce costs, minimize facility footprint and assure on time, every time buffer production.” Moving forward, while this collaboration will provide biopharmaceutical manufacturers with immediate benefit, the value is expected to increase exponentially over time with the open sharing of data and joint testing that will spur innovation at both companies. The MOTIV system will be better acclimated to immediately support a wider variety of pre-mixed buffer concentrates as the variety of the concentrates diversifies. ”We are excited to collaborate with Asahi Kasei Bioprocess to help the biotech industry further address the buffer bottleneck”, said Brian Parker, CEO of GeminiBio. “GeminiBio is committed to helping our customers simplify upstream and downstream process liquid manufacturing, and supporting inline dilution with ready to use buffer concentrates for the MOTIV IBF™ system allows us to provide an even higher level of simplification for our customers.” The partnership between Asahi Kasei Bioprocess America and GeminiBio exemplifies the dedication of the Asahi Kasei Group to its mission of contributing to life and living for people around the world as it paves the way to innovation under their current medium-term management plan: Be a Trailblazer. About Asahi Kasei Bioprocess The Fluid Management Business Unit of Asahi Kasei Bioprocess is devoted to solving therapeutic product safety, efficiency, and purity challenges within the pharmaceutical and bioprocessing industries. With technology platforms for oligonucleotide synthesis, buffer formulation, chromatography, and filtration, our bioprocess systems, columns, and automation solutions advance GMP manufacturing of critical drug substances around the world.

Editas Medicine Announces Publication in Nature Biotechnology of Comprehensive SLEEK Gene Editing Technology Data

Globenewswire | May 02, 2023

Editas Medicine, Inc. a clinical stage genome editing company, announced that the journal Nature Biotechnology published the comprehensive data from a study of the proprietary SLEEK gene editing technology. Despite major progress in achieving gene disruption with CRISPR-Cas gene editing technologies, efficient knock-in of transgenes continues to be a significant challenge for the gene editing field. To solve this challenge, SLEEK was developed to enable high knock-in efficiency with both viral and non-viral transgene formats while also ensuring robust simultaneous expression of up to four transgene cargos. The study demonstrated that utilizing SLEEK results in the knock-in of multiple clinically relevant transgenes through a proprietary process that specifically selects only those cells containing the knock-in cargo. This process was developed by leveraging Editas Medicine’s proprietary engineered AsCas12a nuclease, which can achieve very high editing efficiency while maintaining high specificity. More than 90 percent knock-in efficiencies were observed in various clinically relevant target cells, including T cells, B cells, iPSCs, and NK cells. Additionally, SLEEK can be used to fine-tune the expression levels of transgene cargos, an important feature of next-generation cell therapies. As a demonstration of SLEEK’s potential value in clinical applications, the study authors used SLEEK to generate iPSC-derived NK cells capable of high-levels of in vivo persistence and robust tumor clearance in a solid tumor animal model. “We are thrilled Nature Biotechnology published our paper sharing the comprehensive data on our SLEEK gene editing technology as we believe SLEEK has immense potential for gene editing drug development. As shared in the publication, SLEEK technology enables nearly 100 percent knock-in of functional transgene cargos at specific locations in the genome which may result in highly efficient multi-transgene knock-in for the next generation of cell therapy medicines,” said John A. Zuris, Ph.D., Director of Editing Technologies, Editas Medicine, and senior author on the study. Editas Medicine believes that SLEEK may enable better product purity as well as shorter manufacturing timelines for the next generation of cell therapy medicines. Earlier this year, the Company announced it licensed its interest in the SLEEK technology to Shoreline Biosciences for specific usage in iPSC-derived NK and iPSC-derived macrophage cell therapies for oncology. The SLEEK technology remains an important Editas capability in iPSC engineering for a wide variety of future applications. About Editas Medicine As a clinical stage genome editing company, Editas Medicine is focused on translating the power and potential of the CRISPR/Cas9 and CRISPR/Cas12a genome editing systems into a robust pipeline of treatments for people living with serious diseases around the world. Editas Medicine aims to discover, develop, manufacture, and commercialize transformative, durable, precision genomic medicines for a broad class of diseases.
