  August 24, 2023, The U.S. Food and Drug Administration today approved Tyruko (natalizumab-sztn), the first biosimilar to Tysabri (natalizumab) injection for the treatment of adults with relapsing forms of multiple sclerosis (MS). Tyruko, like Tysabri, is also indicated for inducing and maintaining clinical response and remission in adult patients with moderately to severely active Crohn’s Disease (CD) with evidence of inflammation who have had an inadequate response to, or are unable to tolerate, conventional CD therapies and inhibitors of TNF-α (tumor necrosis factor, a substance in your body that causes inflammation). “Biosimilar medications offer additional effective treatment options that have the potential to increase access for people living with relapsing forms of multiple sclerosis,” said Paul R. Lee, M.D., Ph.D., director of the Division of Neurology 2 in the FDA’s Center for Drug Evaluation and Research. “Today’s approval could have a meaningful impact for patients mana...

  Cell culture consumables are necessary items for culturing cells, and play an important role in creating a good growth environment for cells and ensuring their normal reproduction. Cells are sensitive to the environment, especially the requirements for consumables are relatively high, and one of the most important points is the surface TC treatment. Cell Factory Systems TC treatment is a treatment method, and the cell culture consumables treated with TC can promote cell adherent growth and morphological extension. At present, adherent cell culture is still the mainstream culture method in the market, and most animal cells need to be attached to a solid phase interface to grow. Cells can only attach to a hydrophilic solid phase interface. The earliest cell culture vessels were made of glass. Because the surface of the glass is hydrophilic, the surface can be suitable for cell growth without special treatment. However, most of the cell culture consumables on the market are mainly p...

  Adherent cells are relatively common cell types. The growth of this type of cells must have a support surface that can be attached, and the cells can grow and reproduce on the surface by relying on the attachment factors secreted by themselves or provided in the medium. Commonly used cell culture consumables for culturing adherent cells include   cell factory systems , cell culture roller bottles, and cell culture flasks. Cell factory systems: Cell culture consumables commonly used in large-scale culture, consisting of one or more layers of structure, common ones are 1 layer, 2 layers, 5 layers, 10 layers, 40 layers, etc., and the layers are connected by ultrasonic welding process , the strength of its junction is close to that of a whole piece of continuous material, which can achieve good sealing.

  Most of the cells cultured in vitro belong to adherent cells. The growth of this type of cells must have a support surface that can be attached. Cells can grow and reproduce on the surface by relying on the attachment factors secreted by themselves or provided in the medium. So, what are the requirements for cell culture consumables for adherent cells? Cell Factory Systems The anchorage-dependent cells should be attached to the wall of the culture (flask) vessel during culture. Once the cells are attached to the wall, they will spread rapidly, then start mitosis, and soon enter the logarithmic growth phase. Generally, after a few days, the culture surface will be covered and a dense monolayer of cells will be formed. Cell culture consumables for adherent cells include  cell factory systems , cell culture plates, cell culture roller bottles, etc. At present, most of the cell consumables on the market are polymer materials such as PS, PC, which do not have glass materials. Due...
