Proliferation of mammalian cells with Chlorococcum littorale algal compounds without serum support.

In recent years, serum-free medium for mammalian cell cultivation has attracted a lot of attention, considering the high cost of production and environmental load involved in developing the conventional animal sera. The use of alternative growth-promoting products in mammalian cell cultivation such as extracts from microalgae has proven to be quite beneficial and environmental-friendly. This research aims to cultivate mammalian cells with growth-promoting factors derived from Chlorococcum littorale.

Development of serum-free and grain-derived-nutrient-free medium using microalga-derived nutrients and mammalian cell-secreted growth factors for sustainable cultured meat production.

Considering the amount of global resources and energy consumed, and animal welfare issues associated with traditional meat production, cultured meat production has been proposed as a solution to these problems and is attracting worldwide attention. Cultured meat is produced by culturing/proliferating animal muscle cells in vitro. This process requires significant amounts of culture medium, which accounts to a major portion of the production cost.

Harvest of quality-controlled bovine myogenic cells and biomimetic bovine muscle tissue engineering for sustainable meat production.

Alternative technology for meat production holds the potential to alleviate ethical, environmental, and public health concerns associated with conventional meat production. Cultured meat produced using cell culture technology promises to become a viable alternative to animal-raised meat for the future of the food industry. In this study, biomimetic bovine muscle tissue was artificially fabricated from myogenic cells extracted from bovine meat.

Proliferation and differentiation of primary bovine myoblasts using Chlorella vulgaris extract for sustainable production of cultured meat.

Recently, cultured meat obtained from livestock-derived cells is being considered as a sustainable food source that reduces the use of natural resources. This study aimed to show that nutrients extracted from Chlorella vulgaris were beneficial in the culture of primary bovine myoblasts (PBMs), a major cell source for cultured meat production. Nutrients (glucose, amino acids, and vitamins) present in the animal-cell culture media were effectively recovered from C.

Bioengineering of a scaffold-less three-dimensional tissue using net mould.

Tissue engineering has attracted attention worldwide because of its application in regenerative medicine, drug screening, and cultured meat. Numerous biofabrication techniques for producing tissues have been developed, including various scaffold and printing methods. Here, we have proposed a novel tissue engineering method using a net metal mould without the use of a scaffold.

Exposure to valproic acid during middle to late-stage corticogenesis induces learning and social behavioral abnormalities with attention deficit/hyperactivity in adult mice.

Single prenatal exposure to valproic acid (VPA) in rodents is a widely used preclinical model of autism spectrum disorder (ASD). Continuous prenatal VPA exposure has been recently proposed as a new ASD model that closely captures the neuropathological features of ASD, including increases in cerebral cortex volume and the number of cortical upper layer neurons. We investigated the influence of prenatal VPA exposure on the behavior of adult offspring of pregnant dams that received intraperitoneal injections of VPA twice on one day during the genesis of cortical upper layer neurons.

Human VAPA and the yeast VAP Scs2p with an altered proline distribution can phenocopy amyotrophic lateral sclerosis-associated VAPB(P56S).

A human isoform of the vesicle-associated membrane protein-associated proteins (VAPs), VAPB, causes amyotrophic lateral sclerosis eight due to the missense mutation of Pro-56, whereas human VAPA and the yeast VAP Scs2p proteins are not significantly affected by similar mutations. We have found that VAPA and Scs2p have three prolines present in a conserved region however VAPB has only two prolines in this region. Consequently, this mutation in VAPB (VAPB(P56S)) leaves a single proline in this region whereas other VAPs can retain two proline residues even if the proline equivalent to the Pro-56 is substituted.
