Mesenchymal stromal cells (MSC) are a promising platform for regenerative medicine applications because of their multi-lineage differentiation abilities and ease of collection, isolation, and growth ex-vivo. To meet the demand for clinical applications, large scale manufacturing will be required using three-dimension culture platforms in vessels such as stirred suspension bioreactors. As MSCs are an

Microorganisms build fatty acids with biocatalytic assembly lines, or fatty acid synthases (FASs), that can be repurposed to produce a broad set of fuels and chemicals. Despite their versatility, the product profiles of FAS-based pathways are challenging to adjust without experimental iteration, and off-target products are common. This study uses a detailed kinetic model of the E. coli FAS as a foundation

Formed by aberrant cell division, minicells possess functional metabolism despite their inability to grow and divide. Minicells exhibit not only superior stability when compared with bacterial cells but also exceptional tolerance—characteristics that are essential for a de novo bioreactor platform. Accordingly, we engineered minicells to accumulate protein, ensuring sufficient production capability

After >20 years of research at the intersection of virology and immunology, two brothers have launched a venture seeking to turn arenaviruses into an anticancer virotherapy.

Cancer is one of the major health-related issues affecting the population worldwide and subsequently accounts for the second-largest death. Genetic and epigenetic modifications in oncogenes or tumor suppressor genes affect the regulatory systems that lead to the initiation and progression of cancer. Conventional methods, including chemotherapy/radiotherapy/appropriate combinational therapy and surgery

In large-scale bioreactors, gradients in cultivation parameter such as oxygen, substrate and pH result in fluctuating cell environments. pH fluctuations were identified as a critical parameter for bioprocess performance. Traditionally, scale-down systems at the laboratory scale are used to analyze the effects of fluctuating pH values on strain and thus process performance. Here, we demonstrate the

The non-conventional yeast Kluyveromyces marxianus is widely used for several biotechnological applications, mainly due to its thermotolerance, high growth rate, and ability to metabolise a wide range of sugars. These cell traits are strategic for lignocellulosic biomass valorisation and strain diversity prompts the development of robust chassis, either with improved tolerance to lignocellulosic inhibitors

L-Homoserine is a valuable amino acid as a platform chemical in the synthesis of various important compounds. Development of microbial strains for high-level L-homoserine production is an attractive research direction in recent years. Herein, we converted a wild-type Escherichia coli to a non-auxotrophic and plasmid-free hyperproducer of L-homoserine using systematically metabolic engineer strategies

Phenolic acids and tanshinones are main bioactive compounds produced in Salvia miltiorrhiza widely used in treatment of cardiovascular diseases, which could be promoted by abscisic acid elicitation. However, the regulation mechanism remained to be elucidated. An ABA-inducible IIa WRKY transcription factor (TF) named SmWRKY34 exhibiting high homology with AtWRKY40 was isolated. SmWRKY34 exhibited a

Dietary studies play a crucial role in determining the health-benefiting effects of most food substances, including prebiotics, probiotics, functional foods, and bioactive compounds. Such studies involve gastrointestinal digestion and colonic fermentation of dietary substances. In colonic fermentation, any digested food is further metabolized in the gut by the residing colonic microbiota, causing a

In the ascendant world of mRNA medicines, circular RNA shows promise as an alternative way for making proteins inside human cells.

Metabolic engineering seeks to rewire the metabolic network of cells for the efficient production of value-added compounds from renewable substrates. However, it remains challenging to evaluate and identify strains with the desired phenotype from the vast rational or random mutagenesis library. One effective approach to resolve this bottleneck is to design an efficient high-throughput screening (HTS)

The oxidized kaurene (Ox-Kau) compounds are the core structures of many important diterpenoids with biological activities and economical values. However, easy access to diverse Ox-Kau products is still limited by low natural abundance, and large-scale manufacture remain challenging due to lack of proper heterologous production. To achieve an abundant source alternative to natural extracts, we here

Phospholipids are unique and versatile molecules, essential in a variety of biological systems. Moreover, their diverse structures and amphiphilic properties endorse their indispensable and unparalleled roles in research and industrial-related applications. However, in most cases of applications, naturally occurring phospholipids are either deficit in structural variety or insufficient in quantity;

The biotech sector must devote more resources to cybersecurity — especially those companies that are manufacturers of essential medical products.

Huperzine A (HupA) is a plant-derived lycopodium alkaloid used for the treatment of Alzheimer's disease due to its inhibition against acetylcholinesterase. Currently, industrial production of HupA relies primarily on direct extraction from Huperzia serrate, a perennial herbaceous plant. However, this strategy cannot satisfy the increasing demand for HupA due to scarcity of H. serrate whose growth is

Endochondral ossification is the process of bone formation derived from growing cartilage duringskeletal development. In previous studies, we provoked the osteocyte differentiation of osteoblast precursor cells under a three-dimensional (3D) culture model. To recapitulate the endochondral ossification, the present study utilized the self-organized scaffold-free spheroid model reconstructed by pre-chondrocyte

Cancer cells adapt their intracellular energy metabolism to the oxygen-deprived tumor microenvironment (TME) to ensure tumor progression. This adaptive mechanism has focused attention on the metabolic phenotypes of tumor cells under hypoxic TME for developing novel cancer therapies. Although widely used monolayer (2D) culture does not fully reflect in vivo hypoxic TME, spheroid (3D) culture can produce

5-aminovalerate (AVA) is a platform chemical of substantial commercial value to derive nylon-5 and five-carbon derivatives like δ-valerolactam, 1,5-pentanediol, glutarate, and 5-hydroxyvalerate. De novo bio-production synthesis of AVA using metabolically engineered cell factories is regarded as exemplary route to provide this chemical in a sustainable way. So far, this route is limited by low titers

The overexploitation of fossil fuels has led to a significant increase in atmospheric carbon dioxide (CO2) concentrations, thereby causing problems, such as the greenhouse effect. Rapid global climate change has caused researchers to focus on utilizing CO2 in a green and efficient manner. One of the ways to achieve this is by converting CO2 into valuable chemicals via chemical, photochemical, electrochemical

Cell lysis is an essential step in many studies related to biology and medicine. Based on the scale and medium that cell lysis is carried out, there are three main types of the cell lysis: (1) lysis of the cells in the surrounding environment, (2) lysis of the isolated or cultured cells, and (3) single cell lysis. Conventionally, several cell lysis methods have been developed, such as freeze-thawing
