The Case of Disease-Specific Primary Cells

Image
  Primary cells have also been used in life sciences research, and there is a high demand for these cells. The main advantages of primary cells over immortalised cells are their functional and genetic adherence. Primary cell information is comparable to physiologic significance because these cells lack the biological modifications that enable indefinite in vitro cultivation. However, primary cells pose difficulties. Their supply is constrained, they are difficult to obtain and isolate, they are intolerant of all but the most specific culture conditions, and they don't live long: Primary cells have a maximum of 15 to 20 passages, whereas immortalised cell lines live indefinitely. These issues, however, are usually manageable with meticulous optimization of  culture methods, media, and other factors. Disease-Specific Primary Cells Primary cells require unique environmental and nutritional conditions due to their high level of specialisation in order to grow and maintain the proper p

The Why and How of Serum Removal from Your Cell Culture

Image
  The most important component of cell culture is likely the culture medium, and various commercial media solutions have been developed as a consequence of years of research and development. Serum, most frequently foetal bovine serum, is one common ingredient for cell culture media. However, are you aware of the purpose of this addition and, more significantly, can your cells exist without it? We'll go over the advantages and disadvantages of utilising serum in your cell culture media as well as how to get rid of it if you decide to do so. Importance of Serum in Cell Culture To keep the cells healthy, media contains vitamins, carbohydrates, and buffering agents.  And you frequently add serum, like FBS. This is a key component of cell culture media since it contains lipids and hormones. You'll see a noticeable difference if you take the serum out of your culture medium. Consciously depriving your culture of serum will also limit cell survival and increase apoptosis, so employ t

Primary Cells: A Cruelty-Free Option?

Image
Animal use is required for preclinical investigations in life science research, which is time-consuming, costly, and causes animal cruelty. Animals being used in scientific research and tests has drawn criticism from environmentalists and animal rights activists. Several laws have also been proposed to restrict the use of animals in research. Researchers have been compelled by this to come up with alternatives that will promote compassion for animals while simultaneously reducing the number of animals exploited. In silico computer simulation and in vitro cell cultures are the two main substitutes for in vivo animal experimentation. Cell lines are now a simple tool to study nearly every subject connected to health and disease because of developments in cultural techniques. The ability to easily cultivate cells on dishes makes cell lines an effective tool for experimental studies. Cells can be easily cultivated in small containers at the workstation, and the number of cells can be simpl

The Rise of Mesenchymal Stem Cells in Oncology

Image
  Cancer researchers can improve and hone cell and gene therapy choices to provide individualised medical treatments through the immunomodulatory properties of mesenchymal stem cells. Cancer medicine and therapy developers can alter the functioning of the cells to promote cancer suppression by utilising mesenchymal stem cells' capacity to modify the tumour microenvironment. Mesenchymal stem cells , for instance, present a route to deliver anti-cancer medications to tumour locations due to their propensity to move to tumours. Additionally, researchers can control mesenchymal stem cells via antibody treatment and modify the angiogenesis process, which cancers depend on to thrive. Immunomodulatory effects of MSCs The immunomodulatory characteristics of MSCs offer researchers a powerful weapon against cancer, serving as the foundation for immunotherapy . The development of immune system cells such macrophages, dendritic cells, T cells, B cells, and natural killer cells (NK cells), whi

Dealing With Contaminated Cell Lines: Don’t Miss Your Data

Image
The reproducibility and validity of scientific findings are shaped by a multitude of factors, and precise experimental methodologies, as well as the use of identical experimental substances where applicable, must be recorded. Reproducibility necessitates the characterization of reagents to assure their purity. Cell culture is an essential component of current biomedical research. Multiple quality control techniques, including cell line identification and validation that cell lines are not contaminated, are essential to assuring that reported data is reproducible. Cell line authentication is required to guarantee that cell lines have not been unintentionally incorrectly labelled or cross-contaminated, which could contribute to incorrect disease model interpretations. The necessity of quality control of cell lines used in scientific research cannot be overstated, as it is vital for data reproducibility. Two major hazards in tissue culture are: 1.        Cell Line Authentication: The

In vitro Human Cell Culture Models for Studying Oxidative Stress and Skin Aging

Image
  Ageing is an inescapable process that causes a steady functional impairment in the large majority of organisms. Changes in the looks of skin, which becomes thin, less supple, wrinkled, and far less able to accomplish its defensive role, are one of the most visible indicators of ageing in people. Skin ageing is a multi-faceted phenomenon, and experts are still trying to figure out all of the intricate connections that occur. We do know, however, that it is influenced by both inherent (intrinsic) and external (extrinsic) variables. Intrinsic wrinkles are characterized by skin shrinkage, an enhanced predominance of the vasculature, decreased elasticity, and fine wrinkles, and are mostly genetically driven. Extrinsic causes comprise Exposure to UV radiation and pollution, which cause intense wrinkles, rough texture, and pigmentation anomalies. A mismatch of pro-and anti-oxidants causes oxidative stress, which promotes quicker skin ageing, inflammation, and disease. Currently,  researcher

Human Umbilical Cord derived Mesenchymal Stem Cells

According to The European Review for Medical and Pharmacological Sciences (2016), cells derived from the mesoderm with the ability to undergo self-renewal are mesenchymal stem cells (MSCs). These cells were first described by a team led by Friedenstein as spindle-shaped cells that adhered to the culture vessel from the bone marrow. MSCs can differentiate into several cell types such as chondrocytes (cartilage cells), osteocytes (bone cells), adipocytes (fat cells) and myocytes (muscle). 2016-published research in the Journal of Orthopaedic Surgery and Research by scientists Viganò and team explained that these cells maintain the optimum number of cells in tissues to maintain tissue homeostasis by differentiating into appropriate cells. They also release many growth factors and molecules that regulate the immune system. A team led by Sriramulu (2018) described added features of these cells in the International Journal of hematology-oncology and stem cell research that are
